Market Analysis & Outlook
Automotive IoT refers to the network of connected hardware, communication modules and software platforms that let a vehicle exchange data with other vehicles, roadside infrastructure, mobile networks and cloud-based service platforms. It spans embedded modems fitted at the factory, tethered systems that rely on a paired smartphone, and integrated systems that combine both, supporting functions from navigation and infotainment to remote diagnostics, usage-based insurance and fleet tracking. Buyers span automakers specifying connectivity at the design stage, fleet operators and insurers paying for ongoing data services, and individual vehicle owners purchasing aftermarket connectivity devices.
USD 189 billion of revenue was recorded in the global iot in automotive market in 2025. By 2034 the figure reaches USD 538 billion, a compound annual growth rate of 11.87% through the forecast period, along a series that runs USD 82 billion in 2020, USD 160 billion in 2024, USD 219.5 billion in 2026 and USD 368 billion in 2030.
Composition changes more than the total does. Embedded, at 13.93%, outgrows Tethered at 4.68%, and its share moves from 46% to 55%. Embedded stays the largest line throughout, at USD 86.94 billion in 2025 and USD 295.9 billion in 2034. Embedded and Integrated take share over the period; Tethered and Others give it up while still growing in absolute terms.
Cut by communication type, the largest line is In-Vehicle Communication: 58% of 2025 revenue, worth USD 109.62 billion, and 48% at USD 258.24 billion by 2034. Vehicle-to-Vehicle Communication grows faster at 15.15% against 9.99%, moving from 24% of revenue to 30% by 2034. Both this axis and the type one divide the same revenue, which is why they are alternative views rather than components.
The regional order runs from Asia Pacific at 38% of 2025 revenue down to Middle East and Africa at 4%. Asia Pacific is worth USD 71.82 billion in 2025 and USD 225.96 billion in 2034; North America, second at 27%, moves from USD 51.03 billion to USD 134.5 billion. Because Asia Pacific take share, the revenue added by 2034 concentrates rather than spreading across all five regions.
Coverage extends to five regions, four type lines and five segmentation axes over the full fifteen years. The 2025 total itself is arrived at by triangulating published aggregates against category proxies, not by an independent count, and the splits below are estimated on that same basis, a bound on their precision worth carrying into any use of them.

Key Takeaways
- The global iot in automotive market moves from USD 82 billion in 2020 to USD 189 billion in 2025 and USD 538 billion by 2034, the forecast period compounding at 11.87% a year.
- The largest line by type is Embedded, worth USD 86.94 billion and 46% of revenue in 2025, rising to USD 295.9 billion and 55% by 2034.
- Scenario range for 2034 runs from USD 473.4 billion in the bear case to USD 602.6 billion in the bull case, against a base-case USD 538 billion, the spread a plan built on this forecast has to absorb.
- 38% of 2025 revenue is generated in Asia Pacific, worth USD 71.82 billion and rising to USD 225.96 billion by 2034; Middle East and Africa is smallest at 4%.
- 45% of Asia Pacific's base-year revenue comes from China alone: USD 32.32 billion in 2025, rising to USD 101.68 billion by 2034, which is why it is that region's worked example.
- Fifteen years are reported, 2020 to 2034 with 2025 as the base: revenue, share and growth rate per line, per axis and per region rather than a single blended series.
Market Trends
Revenue Share, By by type
Base year 2025Embedded leads with 46.0% of by type segment revenue.
Share of by type segment revenue, most recent base year.
The global iot in automotive market is shaped over 2026-2034 by three measurable movements: a change in the type mix, a shift in where revenue sits geographically, and the 11.87% rate carrying the total.
All three are changes in mix rather than in direction: nothing contracts, and the movement is in which lines and regions absorb the new revenue.
Embedded grows at more than twice the pace of Tethered. Between 2026 and 2034, 13.93% growth in Embedded against 4.68% in Tethered pulls the type mix apart. Embedded takes its share of revenue from 46% to 55% while Tethered gives up ground, from 22% to 12%. The revenue figures behind that are USD 86.94 billion to USD 295.9 billion and USD 41.58 billion to USD 64.56 billion. Both expand; where a supplier sits on the axis still decides whether it tracks the market.
Growth concentrates in Asia Pacific. Asia Pacific moves from 38% of revenue in 2025 to 42% in 2034, worth USD 71.82 billion rising to USD 225.96 billion. Share moves off the others in turn: North America at 27% moving to 25%, Europe at 26% moving to 24%, Latin America at 5% moving to 5%, Middle East and Africa at 4% moving to 4%, each still growing in revenue terms. Growth is therefore not something a participant inherits from the market; it depends on which regions its revenue is weighted toward.
The series never breaks trajectory. The market moves through USD 82 billion in 2020, USD 160 billion in 2024, USD 189 billion in 2025, USD 219.5 billion in 2026, USD 368 billion in 2030 and USD 538 billion in 2034. No year breaks the trajectory, and the 11.87% forecast rate compares with 18.17% recorded over 2020-2025, a continuation rather than an inflection. For a participant that makes planning a question of capturing a share of steady expansion rather than timing a discontinuity, and it is why the type and regional mixes matter more to a forecast than the headline rate does.
Market Growth Factors
Embedded carries the market's growth rate
Market Drivers
3- 01Embedded carries the market's growth rate
13.93% growth in Embedded, against 11.87% for the market as a whole, moves it from USD 86.94 billion and 46% of revenue in 2025 to USD 295.9 billion and 55% in 2034. Set against 4.68% at the other end of the axis, this is the line that decides whether the market's 11.87% holds. Where a supplier sits on this axis therefore decides whether it grows with the market or below it.
- 02Asia Pacific carries 38% of the base and keeps growing
Asia Pacific is the largest region at USD 71.82 billion in 2025, 38% of global revenue, and reaches USD 225.96 billion by 2034 on a share rising to 42%. North America adds a further 27% at USD 51.03 billion, reaching USD 134.5 billion. Between them they hold most of the base and most of the revenue added over the period, so equal-weighting the regions in a plan misstates where the growth is.
- 03The base has grown every year since 2020
Revenue rose through USD 82 billion in 2020, USD 160 billion in 2024 and USD 189 billion in 2025, a compound 18.17% across the historical period. From there the forecast carries 11.87% through to USD 538 billion in 2034. A forecast extending an observed trend is a different proposition from one proposing a turn, and that is why no ramp is applied: the 11.87% runs evenly across the period.

Drivers contribute 403 Billion and restraints remove 54 Billion, a net 349 Billion, which is the revenue the market adds between the base year and 2034. Contributions are CDI estimates, apportioned so that they reconcile with the forecast rather than being read from it.
Growth in the global iot in automotive market comes from three measurable sources over 2026-2034: the market's own compounding at 11.87%, the share gained by faster-growing type lines, and expansion in the regions taking a larger part of global revenue.
Restraining Factors
What holds the forecast back
Market Restraints
2- 01What holds the forecast back
Bear case assumes continued semiconductor and connectivity-module supply constraints alongside slower regulatory mandate rollout that delays embedded-connectivity adoption in cost-sensitive vehicle segments. On that assumption 2034 revenue lands at USD 473.4 billion rather than the USD 538 billion base case, from the same USD 189 billion 2025 starting point.
- 02Tethered grows below the market rate
With 22% of 2025 revenue (USD 41.58 billion) Tethered is where most of the market sits, and it grows at only 4.68% against the market's 11.87%. Revenue still reaches USD 64.56 billion by 2034 and share still falls to 12%: a drag on the average rather than a decline.
Market Opportunities
Where the forecast could be beaten
Market Opportunities
2- 01Where the forecast could be beaten
The upside path assumes bull case assumes faster OEM adoption of embedded-connectivity mandates and quicker 5G and V2X infrastructure buildout that pulls telematics and fleet-management revenue forward. It ends 2034 at USD 602.6 billion against a USD 538 billion base case, off the same USD 189 billion base year.
- 02The opening is on the type axis, not the regional one
Share on the type axis moves toward Embedded, from 46% in 2025 to 55% in 2034, on 13.93% growth against the market's 11.87% and revenue rising from USD 86.94 billion to USD 295.9 billion. Taking position there does not require displacing whoever holds Embedded, which is the harder and more expensive fight.
Market Challenges
The total depends on a single line
Market Challenges
2- 01The total depends on a single line
One line dominates: Embedded, at 46% of revenue in 2025 and 55% in 2034, worth USD 86.94 billion and USD 295.9 billion. That concentration means the market's own forecast is, to a large extent, a forecast for one type line.
- 02Asia Pacific is largely China
China generates USD 32.32 billion of Asia Pacific's USD 71.82 billion in 2025, 45% of the region, reaching USD 101.68 billion by 2034. A regional number that depends this heavily on one country carries that country's specific conditions inside it, which a reader treating the region as diversified would miss.
Segmentation Analysis
5 axesThe market is divided by type and by communication type, application, vehicle type and sales channel; five axes in all. Revenue does not add across them: each is a different cut of the same total.
All four type lines expand in revenue terms over the forecast period. Share is the dividing line; two take it, the others cede it.
By Type · 4 segments
Embedded Holds the Largest Type Share and Is Still the Quickest to Grow
- Largest Embedded · 46%
- Fastest Embedded · 13.9%
- Moves most Tethered · -10 pts
- Order by 2034 unchanged
| Segment | 2025 | Share | 2034 | Share | CAGR |
|---|---|---|---|---|---|
| Embedded | $86.94B | 46% | $296B | 55%+9 | 13.9% |
| Tethered | $41.58B | 22% | $64.56B | 12%-10 | 4.7% |
| Integrated | $45.36B | 24% | $140B | 26%+2 | 12.9% |
| Others | $15.12B | 8% | $37.66B | 7%-1 | 10.2% |
Embedded systems lead and are growing fastest because automakers increasingly build connectivity in at the factory to satisfy safety and eCall mandates rather than relying on a driver's paired smartphone, while tethered systems lose share as built-in modems become standard equipment; integrated systems hold a steady middle position by combining embedded hardware with app-based features. The order does not change: Embedded is still largest in 2034, and what moves is how much it holds. Every year of the series is priced on this axis, making it the reference cut for the rest of the report.
By Communication Type · 3 segments
In-Vehicle Communication Led by Communication type in 2025, with Vehicle-to-Vehicle Communication Growing Fastest
- Largest In-Vehicle Communication · 58%
- Fastest Vehicle-to-Vehicle Communication · 15.2%
- Moves most In-Vehicle Communication · -10 pts
- Order by 2034 unchanged
| Segment | 2025 | Share | 2034 | Share | CAGR |
|---|---|---|---|---|---|
| In-Vehicle Communication | $110B | 58% | $258B | 48%-10 | 10% |
| Vehicle-to-Vehicle Communication | $45.36B | 24% | $161B | 30%+6 | 15.2% |
| Vehicle-to-Infrastructure Communication | $34.02B | 18% | $118B | 22%+4 | 14.9% |
In-Vehicle communication leads because it underpins every connected-vehicle function regardless of external network availability, covering sensor fusion and ECU messaging that a car needs even with no cellular signal, while Vehicle-to-Vehicle communication grows fastest as automakers add collision-avoidance and platooning features that depend on direct vehicle-to-vehicle data exchange and roadside infrastructure investment gradually catches up with vehicle-side hardware readiness. In-Vehicle Communication remains the largest line through 2034, so the axis changes in proportion rather than in order.
By Application · 4 segments
Scale and Growth Sit in the Same Line on the Application Axis: Telematics
- Largest Telematics · 34%
- Fastest Telematics · 13.7%
- Moves most Telematics · +4 pts
- Order by 2034 unchanged
| Segment | 2025 | Share | 2034 | Share | CAGR |
|---|---|---|---|---|---|
| Telematics | $64.26B | 34% | $204B | 38%+4 | 13.7% |
| Infotainment System | $56.70B | 30% | $145B | 27%-3 | 11% |
| Navigation | $41.58B | 22% | $108B | 20%-2 | 11.1% |
| Other | $26.46B | 14% | $80.70B | 15%+1 | 13.2% |
Telematics leads and is growing fastest because fleet operators and insurers increasingly pay for continuous vehicle data such as usage-based insurance, remote diagnostics and fleet tracking rather than for one-time equipment, while infotainment's growth has slowed as smartphone mirroring displaces dedicated in-car apps; navigation keeps a steady base because automakers keep embedding safety-relevant routing features by default regardless of subscription uptake. By 2034 Telematics is still ahead, making this a shift in weight rather than a change of leader.
By Vehicle Type · 2 segments
Passenger Cars Led by Vehicle type in 2025, with Commercial Vehicles Growing Fastest
- Largest Passenger Cars · 68%
- Fastest Commercial Vehicles · 13.8%
- Moves most Passenger Cars · -4 pts
- Order by 2034 unchanged
| Segment | 2025 | Share | 2034 | Share | CAGR |
|---|---|---|---|---|---|
| Passenger Cars | $129B | 68% | $344B | 64%-4 | 11.6% |
| Commercial Vehicles | $60.48B | 32% | $194B | 36%+4 | 13.8% |
Passenger cars lead in absolute revenue simply on unit volume, since global light-vehicle production far exceeds commercial fleet volumes, but commercial vehicles are growing faster because fleet operators can quantify a direct payback from telematics-driven fuel savings, route optimization and driver-safety monitoring, making IoT adoption an operating-cost decision there rather than a discretionary feature. Commercial Vehicles grows fastest here, so its share rises while Passenger Cars gives ground. By 2034 Passenger Cars is still ahead, making this a shift in weight rather than a change of leader.
By Sales Channel · 2 segments
OEM Holds the Largest Sales channel Share and Is Still the Quickest to Grow
- Largest OEM · 72%
- Fastest OEM · 13.3%
- Moves most OEM · +6 pts
- Order by 2034 unchanged
| Segment | 2025 | Share | 2034 | Share | CAGR |
|---|---|---|---|---|---|
| OEM | $136B | 72% | $420B | 78%+6 | 13.3% |
| Aftermarket | $52.92B | 28% | $118B | 22%-6 | 9.3% |
OEM-fitted systems lead and are growing fastest because automakers now build connectivity in at the factory to support over-the-air updates and embedded safety mandates, leaving aftermarket devices to serve mainly older vehicles already on the road; aftermarket still grows in absolute terms as fleet owners retrofit existing vehicles, just at a slower pace than the OEM channel expands. By 2034 OEM is still ahead, making this a shift in weight rather than a change of leader.

North America Market Analysis
The 2nd-largest region covered — 2 points of share move elsewhere by 2034, while revenue still grows 2.6×.
- Rank 2 of 5
- 2025 share 27%
- By 2034 25%
- Revenue $51.03B → $135B
In North America, 27% of global revenue puts 2025 at USD 51.03 billion on the way to USD 134.5 billion by 2034. Among the five regions it ranks second by revenue in both years.
Share settles at 25% in 2034, a shift in share rather than in direction: revenue climbs every year while the market's centre of gravity moves elsewhere.
Within the region the type split tracks the global one; 46% of 2025 revenue in Embedded, fastest growth of 13.93% in Embedded. Revenue for North America is broken out by every segmentation axis and by country in the full report.
United States
Sets the pace for North America at 85% of it, growing 2.6×.
- In region 1 of 3
- Of region 85%
- Of global 23%
- Revenue $43.40B → $114B
USD 43.4 billion of North America's 2025 revenue is generated in the United States, the region's largest market, reaching USD 114.3 billion by 2034. Because it is 85.05% of the region in the base year, North America's totals move with this one country rather than with a spread of them. The region itself runs USD 51.03 billion to USD 134.5 billion over the same period, and this is the market carrying the country-level detail in the full report.
The type pattern in the United States is the global one: 46% of 2025 revenue in Embedded, 55% by 2034, against 13.93% growth in Embedded taking it from 46% to 55%. Because the country carries 85.05% of North America, a movement in its own mix shows up in the regional totals rather than being averaged away by neighbouring markets. Revenue by type for the United States is reported separately in the full report.
In the United States, connected and IoT-enabled automotive systems fall under a layered oversight structure rather than a single regulator. The National Highway Traffic Safety Administration oversees the safety implications of embedded connectivity and software features through the Federal Motor Vehicle Safety Standards, while the Federal Communications Commission governs the radio-frequency modules, telematics units, and wireless transceivers these systems rely on, requiring equipment authorization before sale. Suppliers must also account for federal and state privacy expectations around vehicle-generated data, alongside voluntary cybersecurity guidance from NHTSA and standards bodies such as SAE International. Conformity typically involves demonstrating compliance with relevant SAE and ISO standards for automotive electronics and cybersecurity management.
Competition in the United States runs between the suppliers this study tracks: Thales SA, Texas Instruments, TomTom, Cisco, Intel Corporation, NXP Semiconductors, Vodafone, AT&T, Continental AG, Robert Bosch GmbH, HARMAN International, Qualcomm Technologies, Verizon Communications and Aptiv PLC. One line leads on both counts here: Embedded holds 46% of 2025 revenue and compounds fastest at 13.93%. Per-company positioning and share at country level are in the full report only.
Canada
2nd-largest in North America, growing 2.6×.
- In region 2 of 3
- Of region 10%
- Of global 2.7%
- Revenue $5.10B → $13.45B
2.7% of global revenue is generated in Canada; USD 5.1 billion in 2025, reaching USD 13.45 billion in 2034, and 9.99% of North America.
Mexico
3rd-largest in North America, growing 2.6×.
- In region 3 of 3
- Of region 5%
- Of global 1.4%
- Revenue $2.55B → $6.73B
Within North America, Mexico accounts for 5% of regional revenue and 1.35% of the global total, worth USD 2.55 billion in 2025 and USD 6.73 billion by 2034.
Europe Market Analysis
The 3rd-largest region covered — 2 points of share move elsewhere by 2034, while revenue still grows 2.6×.
- Rank 3 of 5
- 2025 share 26%
- By 2034 24%
- Revenue $49.14B → $129B
Europe holds 26% of the global iot in automotive market in 2025, worth USD 49.14 billion with USD 129.12 billion projected for 2034. By revenue it sits third across the study, and the ranking does not change between 2025 and 2034.
Share settles at 24% in 2034, a shift in share rather than in direction: revenue climbs every year while the market's centre of gravity moves elsewhere.
Embedded leads here as it does globally, at 46% of 2025 revenue, and Embedded again grows fastest at 13.93%. Revenue for Europe is broken out by every segmentation axis and by country in the full report.
Germany
The largest market in Europe, growing 2.6×.
- In region 1 of 3
- Of region 30%
- Of global 7.8%
- Revenue $14.74B → $38.74B
USD 14.74 billion of Europe's 2025 revenue is generated in Germany, the region's largest market, reaching USD 38.74 billion by 2034. 30% of the region in the base year makes it the largest market here without making it the region. Set against USD 49.14 billion and USD 129.12 billion for the region, it is why this market rather than a smaller one is the one reported in full.
Composition here matches the global split: the largest line is Embedded at 46% of 2025 revenue, easing to 55% by 2034, and the fastest is Embedded at 13.93%, from 46% to 55%. With 30% of Europe concentrated here, a change in this country's mix is visible in the regional figures instead of being diluted by its neighbours. Revenue by type for Germany is reported separately in the full report.
In Germany, automotive IoT hardware is regulated within the European Union's type-approval framework, administered nationally by the Kraftfahrt-Bundesamt, which confirms that connected vehicle systems meet EU vehicle safety and cybersecurity requirements, including the UNECE regulation on cybersecurity management systems that now underpins EU type approval. Wireless communication modules must additionally satisfy the Radio Equipment Directive and carry CE marking before being placed on the market. Data generated by connected systems is subject to the General Data Protection Regulation, requiring suppliers to establish a lawful basis for collection and clear disclosure to vehicle owners. Suppliers are expected to document conformity assessments and maintain technical files demonstrating adherence to harmonised standards.
Competition in Germany runs between the suppliers this study tracks: Thales SA, Texas Instruments, TomTom, Cisco, Intel Corporation, NXP Semiconductors, Vodafone, AT&T, Continental AG, Robert Bosch GmbH, HARMAN International, Qualcomm Technologies, Verizon Communications and Aptiv PLC. Embedded is both the largest line, at 46% of 2025 revenue, and the fastest-growing at 13.93%.

Asia Pacific Market Analysis
The largest region covered, and the one gaining the most — it picks up 4 points of share by 2034, while revenue still grows 3.1×.
- Rank 1 of 5
- 2025 share 38%
- By 2034 42%
- Revenue $71.82B → $226B
Asia Pacific holds 38% of the global iot in automotive market in 2025, worth USD 71.82 billion with USD 225.96 billion projected for 2034. Among the five regions it ranks first by revenue in both years.
42% of global revenue sits here by 2034, up from the 2025 level, on growth above the market's own 11.87%, and with a bigger contribution to the revenue added over the period than the base-year figure suggests.
Within the region the type split tracks the global one; 46% of 2025 revenue in Embedded, fastest growth of 13.93% in Embedded. Revenue for Asia Pacific is broken out by every segmentation axis and by country in the full report.
China
The largest market in Asia Pacific, growing 3.1×.
- In region 1 of 3
- Of region 45%
- Of global 17.1%
- Revenue $32.32B → $102B
China is the largest market within Asia Pacific, generating USD 32.32 billion in 2025 and projected to reach USD 101.68 billion by 2034. At 45% of the region in 2025 it leads, but a majority of Asia Pacific's revenue is generated in other markets. The region itself runs USD 71.82 billion to USD 225.96 billion over the same period, and this is the market carrying the country-level detail in the full report.
China buys along the same lines as the market globally; Embedded first at 46% of 2025 revenue and 55% in 2034, Embedded fastest at 13.93% on a share moving from 46% to 55%. Since 45% of Asia Pacific's revenue is generated here, the regional numbers inherit this market's mix rather than smoothing it out. Revenue by type for China is reported separately in the full report.
In China, connected automotive devices are regulated primarily by the Ministry of Industry and Information Technology, which oversees telematics terminals, in-vehicle wireless modules, and connected-vehicle data handling under its automotive and telecommunications equipment rules. Radio-emitting components generally require type approval and China Compulsory Certification before sale, alongside conformity to national standards issued through the Standardization Administration. Given the sensitivity of vehicle-generated data, suppliers must also navigate the Cybersecurity Law and the Data Security Law, which impose requirements around data localisation, security assessment, and cross-border transfer approval for connected-vehicle information. Compliance generally requires coordination between telecommunications, industrial, and cybersecurity authorities rather than a single approval pathway.
The suppliers tracked in this study (Thales SA, Texas Instruments, TomTom, Cisco, Intel Corporation, NXP Semiconductors, Vodafone, AT&T, Continental AG, Robert Bosch GmbH, HARMAN International, Qualcomm Technologies, Verizon Communications and Aptiv PLC) compete in China across the type lines above. Embedded is both the largest line, at 46% of 2025 revenue, and the fastest-growing at 13.93%.

- In region 2 of 3
- Of region 20%
- Of global 7.6%
- Revenue $14.36B → $45.19B
7.6% of global revenue is generated in Japan; USD 14.36 billion in 2025, reaching USD 45.19 billion in 2034, and 20% of Asia Pacific.
South Korea
3rd-largest in Asia Pacific, growing 3.1×.
- In region 3 of 3
- Of region 12%
- Of global 4.6%
- Revenue $8.62B → $27.12B
4.56% of global revenue is generated in South Korea; USD 8.62 billion in 2025, reaching USD 27.12 billion in 2034, and 12% of Asia Pacific.
Latin America Market Analysis
The 4th-largest region covered, holding its share flat through 2034, while revenue still grows 2.8×.
- Rank 4 of 5
- 2025 share 5%
- By 2034 5%
- Revenue $9.45B → $26.90B
Latin America holds 5% of the global iot in automotive market in 2025, worth USD 9.45 billion rising to USD 26.9 billion in 2034. It is a marginal region on this axis, fourth by revenue throughout the period.
5% of global revenue sits here in 2034, below the 2025 level, a shift in share rather than in direction: revenue climbs every year while the market's centre of gravity moves elsewhere.
The type mix reported at global level applies here, with Embedded the largest line at 46% of 2025 revenue and Embedded the fastest-growing at 13.93%. Per-axis and per-country detail for Latin America sits in the full report.
Brazil
The largest market in Latin America, growing 2.8×.
- In region 1 of 2
- Of region 55%
- Of global 2.8%
- Revenue $5.20B → $14.80B
55.03% of Latin America's base-year revenue comes from Brazil; USD 5.2 billion, rising to USD 14.8 billion by 2034. Its 55.03% of base-year regional revenue leads the region, though enough sits elsewhere that Latin America is not a proxy for it. Against regional totals of USD 9.45 billion in 2025 and USD 26.9 billion in 2034, it is the country the full report breaks out in detail.
Brazil buys along the same lines as the market globally; Embedded first at 46% of 2025 revenue and 55% in 2034, Embedded fastest at 13.93% on a share moving from 46% to 55%. Since 55.03% of Latin America's revenue is generated here, the regional numbers inherit this market's mix rather than smoothing it out. The full report reports Brazil by type separately.
In Brazil, wireless-enabled automotive components must obtain homologation from Anatel, the national telecommunications regulator, before any radio-frequency module can be sold or installed in a vehicle. Vehicle-level standards and safety requirements are set by Contran, while Inmetro administers certification of electrical and electronic automotive parts against applicable technical regulations. Suppliers of connected systems must also comply with the Lei Geral de Proteção de Dados, Brazil's general data protection law, which governs the collection and processing of telematics and location data generated by IoT-enabled vehicles. Taken together, market entry for connected automotive hardware depends on coordinated approval across telecommunications, vehicle-safety, and data-protection authorities.
Thales SA, Texas Instruments, TomTom, Cisco, Intel Corporation, NXP Semiconductors, Vodafone, AT&T, Continental AG, Robert Bosch GmbH, HARMAN International, Qualcomm Technologies, Verizon Communications and Aptiv PLC are the suppliers covered in Brazil. One line leads on both counts here: Embedded holds 46% of 2025 revenue and compounds fastest at 13.93%.
Argentina
2nd-largest in Latin America, growing 2.8×.
- In region 2 of 2
- Of region 15%
- Of global 0.8%
- Revenue $1.42B → $4.04B
Within Latin America, Argentina accounts for 15.03% of regional revenue and 0.75% of the global total, worth USD 1.42 billion in 2025 and USD 4.04 billion by 2034.
Middle East and Africa Market Analysis
The 5th-largest region covered, holding its share flat through 2034, while revenue still grows 2.8×.
- Rank 5 of 5
- 2025 share 4%
- By 2034 4%
- Revenue $7.56B → $21.52B
In Middle East and Africa, 4% of global revenue puts 2025 at USD 7.56 billion with USD 21.52 billion projected for 2034. Among the five regions it ranks fifth by revenue in both years.
By 2034 the share stands at 4%, while nothing contracts here; other regions simply grow faster, which shows up as relative weight rather than as falling revenue.
Segment composition follows the global pattern: Embedded largest at 46% of 2025 revenue, Embedded fastest at 13.93%. Middle East and Africa is reported axis by axis and country by country in the full study.
Saudi Arabia
The largest market in Middle East and Africa, growing 2.8×.
- In region 1 of 2
- Of region 35%
- Of global 1.4%
- Revenue $2.65B → $7.53B
The largest single market in Middle East and Africa is Saudi Arabia, at USD 2.65 billion in 2025 and USD 7.53 billion in 2034. Its 35.05% of base-year regional revenue leads the region, though enough sits elsewhere that Middle East and Africa is not a proxy for it. Against regional totals of USD 7.56 billion in 2025 and USD 21.52 billion in 2034, it is the country the full report breaks out in detail.
Composition here matches the global split: the largest line is Embedded at 46% of 2025 revenue, easing to 55% by 2034, and the fastest is Embedded at 13.93%, from 46% to 55%. With 35.05% of Middle East and Africa concentrated here, a change in this country's mix is visible in the regional figures instead of being diluted by its neighbours. Saudi Arabia carries its own type breakdown in the full report.
In Saudi Arabia, automotive IoT components are regulated through the Saudi Standards, Metrology and Quality Organization, which sets conformity requirements for automotive electronic and electrical parts entering the market, often aligned with international standards adopted locally. Wireless communication modules additionally require type approval from the Kingdom's telecommunications regulator, the Communications, Space and Technology Commission, before they may transmit locally. Suppliers must demonstrate conformity through recognised testing and certification schemes and affix the required conformity mark to qualifying components. As connected-vehicle data handling expands, suppliers are also expected to align with the Kingdom's personal data protection regime governing how telematics and location information is collected and stored.
Competition in Saudi Arabia runs between the suppliers this study tracks: Thales SA, Texas Instruments, TomTom, Cisco, Intel Corporation, NXP Semiconductors, Vodafone, AT&T, Continental AG, Robert Bosch GmbH, HARMAN International, Qualcomm Technologies, Verizon Communications and Aptiv PLC. Volume and growth sit in the same line — Embedded, at 46% of 2025 revenue and 13.93% growth.
United Arab Emirates
2nd-largest in Middle East and Africa, growing 2.8×.
- In region 2 of 2
- Of region 25%
- Of global 1%
- Revenue $1.89B → $5.38B
1% of global revenue is generated in the United Arab Emirates; USD 1.89 billion in 2025, reaching USD 5.38 billion in 2034, and 25% of Middle East and Africa.

Competitive Landscape
Position on the Type Axis Decides Competitive Standing
Suppliers in scope: Thales SA, Texas Instruments, TomTom, Cisco, Intel Corporation, NXP Semiconductors, Vodafone, AT&T, Continental AG, Robert Bosch GmbH, HARMAN International, Qualcomm Technologies, Verizon Communications and Aptiv PLC.
The type axis, not the regional one, is where competition happens. 46% of 2025 revenue, worth USD 86.94 billion, is in Embedded, still 55% of the total in 2034; that is the position least likely to change hands. Embedded, compounding at 13.93% against 4.68% for Tethered, is where share changes hands over the forecast period. Those are different problems, and a supplier strong in one is not thereby strong in the other; that is what sustains a field this size in a USD 189 billion market.
In automotive IoT, the deciding capabilities are semiconductor and module manufacturing scale, since automotive-grade components must pass multi-year qualification cycles most suppliers cannot repeat quickly; established relationships with automakers that shorten those qualification cycles on future platforms; network-operator partnerships that secure global data-roaming coverage for connected services; and software-platform breadth spanning infotainment, telematics and over-the-air update management rather than a single point product. The largest suppliers compete on qualified manufacturing scale and OEM design-in relationships, while smaller and regional players compete on faster integration for aftermarket and fleet-retrofit channels the larger suppliers serve less directly.
Geographic reach is the other axis of competition. Asia Pacific alone accounts for 38% of 2025 revenue, so a supplier absent there is absent from the largest part of the market whatever its position elsewhere; North America adds a further 27%.

Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
Automotive IoT revenue in this study is built bottom-up from the installed base of vehicles receiving embedded, tethered or integrated connectivity, multiplied by connectivity-module average selling price and the recurring data or subscription fee attached to each unit. Fleet-telematics volumes are estimated from commercial-vehicle parc figures and reported attach rates for usage-based insurance and remote-diagnostics programs. This bottom-up build is checked against top-down automotive-electronics and connected-services expenditure reported by tier-one suppliers and mobile network operators; where the two diverge, the unit-price or attach-rate assumption feeding the bottom-up build is revisited rather than the two figures being averaged. Regional splits follow vehicle production volumes and connectivity-mandate timing by market.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research for this market targets procurement and product-planning executives at automakers and tier-one suppliers who set connectivity specifications, telematics service providers and mobile network operators who price data plans, and fleet-management and insurance buyers who set attach-rate expectations for commercial vehicles. Regulatory contacts covering eCall and connected-safety mandates in Europe and China are included given how directly those rules affect embedded-adoption timing. Sampling weights toward China, the United States, Germany and Japan, the four markets that combine the largest vehicle production volumes with the earliest connectivity mandates, supplemented by aftermarket and insurance-channel contacts in markets where retrofit adoption still leads OEM fitment.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
