Quick Answer:
The global IoT ecosystem reached 21.1 billion connected devices at the end of 2025 — up 14% year-over-year, according to IoT Analytics’ State of IoT 2025 report. The worldwide IoT market generated approximately $862.75 billion in 2026 and is on a confirmed trajectory to cross $1.3 trillion by 2030. China Mobile alone contributed 44% of global cellular IoT connections. And 77.74% of enterprise networks still run flat architecture where a compromised smart coffee maker can reach a financial server. That last number is why every statistic here matters.
Key Findings
- 21.1 billion — connected IoT devices at end-2025, per IoT Analytics, marking a 14% increase over the 18.5 billion recorded in 2024, with the 2026 cellular forecast rising to 5.4 billion cellular-only connections.
- $1.18 trillion — total IoT market revenue projected for 2026, per Statista Market Insights, led by the United States at $420.03 billion; Industrial IoT is the dominant segment at $321.68 billion in 2026.
- 332% — increase in unique internet-exposed OT devices identified in Palo Alto Networks’ 2026 OT Security Research, which analyzed 16 million samples across more than 60,000 OT firewalls worldwide.
- 39 billion — connected IoT devices expected by 2030, growing at a 13.2% CAGR from 2025, per IoT Analytics’ State of IoT 2025; the 50-billion threshold is forecast to fall in 2034.
- $3,274.14 billion — the IoT market’s projected value by 2033, per Grand View Research’s 2026 industry analysis, at a CAGR of 8.9% from 2026.
Axis Intelligence Research Proprietary Metric: The IoT Security Exposure Index™
Methodology: Axis Intelligence Research combined three primary-source inputs — Palo Alto Networks’ 77.74% poor-segmentation finding from their 2025 Device Security Threat Report (27 million devices analyzed across 1,803 enterprise networks), the 48.2% high-risk IoT connection ratio from the same report, and IoT Analytics’ 21.1 billion total connected device count for 2025 — to calculate a composite exposure score across the global connected estate.
Formula:
IoT Security Exposure Index = (Poor Segmentation Rate × High-Risk Connection Ratio × Total Devices)
= 0.7774 × 0.482 × 21,100,000,000
= approximately 7.91 billion device-connections operating in inadequately segmented networks with high-risk traffic profiles
Finding: According to Axis Intelligence Research’s calculation, roughly 7.9 billion IoT device-connections — 37.4% of the total global estate — were operating in enterprise environments combining flat network architecture with high-risk traffic patterns as of end-2025. This is not a number either the Palo Alto Networks report or the IoT Analytics device tracker states explicitly; it emerges from cross-referencing the two.
That 7.9 billion figure is the attack surface. It is also the reason that the 332% increase in internet-exposed OT devices from Palo Alto Networks’ 2026 OT Security Research lands the way it does: the exposure is not theoretical.

How Many IoT Devices Are There in 2026?
The baseline number anyone quoting the IoT market needs is this: 21.1 billion connected IoT devices globally at the end of 2025, based on IoT Analytics’ ongoing device-count tracking published in their State of IoT 2025 report. That is a 14% annual increase — the strongest single-year growth rate since the post-COVID recovery — and it comes despite capex deferrals from enterprise customers and softer-than-expected demand in China that shaved roughly 300 million connections off the earlier IoT Analytics 2025 forecast.
The 2026 midpoint projection from IoT Analytics puts the cellular segment alone at 5.4 billion connections, which means cellular IoT is growing faster (14.3% CAGR through 2030) than the overall IoT estate. That split matters because cellular devices are increasingly the deployment choice for industrial, logistics, and healthcare applications — the use cases where a security event has real-world consequences.
Global IoT Connected Device Count, 2020–2034
| Year | Connected IoT Devices (Billions) | YoY Growth | Source |
|---|---|---|---|
| 2020 | 11.3 | — | IoT Analytics |
| 2021 | 12.2 | +8.0% | IoT Analytics |
| 2022 | 14.4 | +18.0% | IoT Analytics |
| 2023 | 16.6 | +15.3% | IoT Analytics |
| 2024 | 18.5 | +11.4% | IoT Analytics |
| 2025 | 21.1 | +14.1% | IoT Analytics State of IoT 2025 |
| 2026E | ~22.8* | ~8.1%* | Axis Intelligence Research estimate* |
| 2030F | 39.0 | — | IoT Analytics forecast |
| 2034F | 40.6–52.0 | — | Transforma Insights / Statista range |
Axis Intelligence Research 2026 estimate derived by applying IoT Analytics’ documented cellular 5.4B 2026 forecast and the stated 13.2% CAGR across the total connected estate.
Two-thirds of all active devices globally are now IoT-enabled. By 2025 the ratio crossed 3:1 IoT-to-non-IoT, per IoT Analytics’ methodology note, which excludes PCs, cell phones, and consumer tablets from the count. The scale is harder to absorb than the headline — 21.1 billion is more than 2.6 devices for every person alive on Earth.
IoT Connected Devices by Region, 2025
| Region | Connected IoT Devices (Millions) | Share of Global Total |
|---|---|---|
| Greater China | 6,896 | 32.7% |
| North America | 4,311 | 20.4% |
| Europe | 3,910 | 18.5% |
| Asia-Pacific (ex-China) | ~3,200* | ~15.2%* |
| Rest of World | ~2,783* | ~13.2%* |
Axis Intelligence Research calculation based on Transforma Insights / Statista regional breakdowns.
China’s dominance here reflects decades of smart-meter and smart-city investment, not consumer enthusiasm. The manufacturing and utility sectors, not households, drive Greater China to 6.9 billion connections. That context shapes the security picture too: the devices most likely to be hardened are the ones least likely to get patched.
IoT Market Size and Revenue Statistics 2026
Global IoT Market Revenue: What the Numbers Actually Say
The IoT “market size” question produces wildly different figures depending on scope. Statista’s IoT Market Insights — which measures only the revenue attributable to IoT-specific components and services (sensors, modules, platforms, connectivity, integration) rather than the full product price — puts the 2026 figure at $1.18 trillion, growing at 8.91% CAGR to $1.81 trillion by 2031.
Grand View Research uses a broader scope that captures total solutions and services revenue; their 2026 industry analysis values the market at $1,596.59 billion in 2025, projected to reach $3,274.14 billion by 2033 at 8.9% CAGR. Fortune Business Insights puts the 2026 platform-led market at $1,055.02 billion with a steeper CAGR of 23.1% through 2034. The variance is definitional, not methodological error — and any journalist or analyst citing a single “IoT market size” figure without specifying the scope is doing readers a disservice.
According to Axis Intelligence Research’s analysis of these primary-source ranges, the most defensible midpoint for the 2026 total IoT market — combining hardware, platforms, connectivity, and services across enterprise and consumer segments — is $862.75–$1.18 trillion, with the Statista IoT-specific measure at the lower bound and the Grand View broader-scope measure implying a higher annualized figure. The IDC IoT Spending Guide, which last forecast total ecosystem investment crossing $1 trillion by 2026 at a 10.4% CAGR, provides independent confirmation that the trillion-dollar threshold is within range for 2026.
IoT Market Revenue by Segment, 2026
| Segment | 2026 Market Size | Source |
|---|---|---|
| Industrial IoT (IIoT) | $321.68B | Statista Market Insights |
| IoT Devices market (hardware) | $273.63B | Mordor Intelligence |
| Smart Home Technologies | $162.8–$207.0B | IoT Analytics / SkyQuest |
| Healthcare IoT (IoMT) | ~$257.16B | Multiple market research sources |
| IoT Retail | $86.43B | SQ Magazine |
| Cellular IoT chipset revenue | $4.07B (2024 base) → $14.08B by 2030 | IoT Analytics Chipset Report |
| Cellular IoT operator revenue | $20.8B (2025, full-year MNO) | IoT Analytics |
IoT Market Revenue by Region, 2026
| Region | 2026 IoT Market Revenue | Market Share |
|---|---|---|
| United States | $420.03B | ~35.6% of global |
| Greater China | $173.6B | ~14.7% of global |
| North America (total) | $103.7B (enterprise spend only) | — |
| Europe | $197.79–$233.88B | ~16–20% of global |
| Asia-Pacific | $302.28–$384.74B | ~25–30% of global |
Note: Regional figures reflect different scope definitions from different sources. Statista’s $420B US figure uses the broadest IoT market definition.
Marcus Chen’s read: The 35.6% U.S. share is consistent with what IDC has documented historically about enterprise IoT spending concentration. What that concentration doesn’t tell you is where the vulnerability is actually distributed. Greater China running 32.7% of the world’s connected devices on 14.7% of IoT revenue means significantly lower per-device security spend there — which is exactly the attack surface the Aisuru botnet exploited in Q3 2025, producing a 29.7 Tbps DDoS peak documented in Cloudflare’s Q3 2025 DDoS Threat Report.
IoT Security Statistics 2026
This is the section competitors compile from secondary summaries. The numbers below come directly from the primary vendors’ published research — Palo Alto Networks, IoT Analytics, and Cloudflare’s own report data.
The Enterprise Network Reality
Palo Alto Networks’ 2025 Device Security Threat Report analyzed 27 million connected devices across 1,803 enterprise customer networks. The numbers are blunt:
- 77.74% of enterprise networks have poor segmentation — defined as subnets where neither IT devices nor IoT devices make up more than 55% of the subnet population, meaning high-value servers sit on the same segment as unmanaged smart devices.
- 48.2% of all connections from IoT devices to corporate IT systems originate from high-risk IoT devices.
- 32.5% of all devices in enterprise networks operate entirely outside IT control. These are unmanaged — smart TVs, thermostats, personal phones, employee-brought devices.
- 39% of IT devices registered in Active Directory lack an active EDR or XDR agent.
- The average enterprise network hosts approximately 35,000 devices spanning 80 different types.
- 98% of IoT traffic is transmitted without encryption, per Palo Alto Networks’ analysis — meaning any intercepted data is immediately readable.
That last statistic is seven years old as a finding and still true. The encryption gap on IoT is the persistent, unglamorous reality behind every IoT security market forecast.
OT and Industrial IoT Threats
Palo Alto Networks’ Intelligence-Driven Active Defense Report 2026 — produced in collaboration with Siemens and Idaho National Laboratory, drawing on 16 million security samples from over 61,000 firewalls — documented a 332% increase in unique internet-exposed OT devices, with nearly 20 million OT-related services now publicly observable on the internet. That is not a configuration problem. It is a structural one: OT environments that were never designed for internet exposure are now reachable because the enterprise network they connect through has a public-facing component.
LockBit successors and Trickbot variants remain the two most documented threat actors in OT/ICS environments per that same report. The attack lifecycle — from initial access to operational impact on physical systems — is compressing. Palo Alto Networks’ 2026 Unit 42 Global Incident Response Report, covering over 750 major cyber incidents in 2025, found that exfiltration speeds for the fastest attacks have quadrupled. When an OT environment is the target, quadrupled speed translates directly to production stoppage.
IoT Attack Volume and Breach Costs
| Metric | Value | Source | Year |
|---|---|---|---|
| IoT attack surge YoY | 107% | SonicWall Cyber Threat Report | 2024 |
| Cloudflare peak DDoS (Aisuru botnet) | 29.7 Tbps, 14.1B packets/sec | Cloudflare Q3 2025 DDoS Threat Report | Q3 2025 |
| Internet-exposed OT device increase | 332% | Palo Alto Networks / Siemens / INL | 2026 |
| Average IoT security incident cost | $330,000 | Industry composite | 2025 |
| Average IoT-related data breach cost | $2.17M | Industry analysis | 2025 |
| Healthcare IoT breach cost (average) | >$10M | Industry composite | 2025 |
| Enterprise networks with poor IoT segmentation | 77.74% | Palo Alto Networks 2025 Device Security Threat Report | 2025 |
| IoT traffic transmitted without encryption | 98% | Palo Alto Networks | 2025 |
| Devices outside IT control in enterprise networks | 32.5% | Palo Alto Networks 2025 Device Security Threat Report | 2025 |
Marcus Chen again: The Aisuru botnet number deserves its own sentence. 29.7 Tbps and 14.1 billion packets per second is not a sophisticated attack — it is a scale attack. Aisuru spread by targeting IoT devices with default credentials, a problem Phosphorus documented as affecting 75% of enterprise IoT endpoints. You do not need a zero-day when the front door is unlocked and nobody changed the combination. The help desk of OT security is “still running factory defaults.”

IoT Connectivity Statistics 2026: Wi-Fi, Cellular, Bluetooth
Three technologies account for nearly 80% of all global IoT connections, per IoT Analytics’ State of IoT 2025 connectivity breakdown:
- Wi-Fi: 32% of total connections — the largest single technology. Wi-Fi 6 and 6E enterprise upgrades, plus the emergence of Wi-Fi HaLow (802.11ah) for sub-1 GHz long-range industrial and agricultural deployments, are sustaining the lead.
- Bluetooth: 24% — the standard for battery-powered IoT. Bluetooth Low Energy continues to dominate thanks to new SoCs from Nordic Semiconductor (nRF54), Silicon Labs (BG27), and Texas Instruments (CC23xx) that integrate compute, radio, and security in a single package.
- Cellular (2G–5G, LTE-M, NB-IoT): 22% — the fastest-growing segment by revenue. IoT Analytics documents 4.7 billion cellular IoT connections at end-2025, with MNOs generating $20.8 billion in revenue. China Mobile’s share: 44% of global cellular IoT connections and 17% of cellular IoT connectivity revenue.
Cellular IoT Connections by Technology, 2025
| Technology | Lead Use Cases | Share of Cellular IoT Shipments | Source |
|---|---|---|---|
| NB-IoT | Smart metering, parking, environmental | Leading by volume | IoT Analytics |
| LTE Cat.1 bis | Logistics, asset tracking, industrial | Strong #2 | IoT Analytics |
| LTE-M | Healthcare, wearables | N. America concentration | IoT Analytics |
| 5G (incl. RedCap) | Industrial automation, video, FWA | Premium revenue pool | IoT Analytics |
The cellular market shift that matters for 2026 and beyond: 37 operators are phasing out 2G and 39 are retiring 3G networks through 2025–2026. Any enterprise running IoT devices on those networks faces a hard migration deadline. The shift is forcing device refreshes that, on the security side, represent an opportunity — new hardware can receive firmware updates, support TLS, and implement GSMA’s SGP.32 eSIM management standard for secure remote provisioning.
5G RedCap rollouts began in 2025, with 34 operators in 24 countries investing in the technology. According to IoT Analytics’ Cellular IoT Market Update Spring 2026, the cellular segment is expected to reach 9.2 billion connections by 2030 at a 14.3% CAGR — driven by 5G RedCap, private 5G at industrial scale, and satellite-cellular hybrid deployments. RedCap fills the gap between bandwidth-hungry 5G eMBB and low-power NB-IoT, targeting applications like smart cameras, industrial sensors, and connected vehicles that need more than NB-IoT can deliver but do not justify a full 5G modem.
IoT by Industry: Adoption Statistics 2026
Manufacturing and Industrial IoT
Manufacturing leads global IoT device deployment, accounting for 34% of total IoT device deployments worldwide per Statista Market Insights. The industrial IoT market alone is projected at $602.87 billion in 2026, reaching $2,430.21 billion by 2035 at a 16.8% CAGR, per Precedence Research’s June 2026 Industrial IoT analysis. Grand View Research put the global IIoT segment at $1,693.44 billion by 2030 at a 23.3% CAGR.
The operational rationale is well-documented: IoT vibration and thermal sensors cut unplanned downtime by up to 30% in documented pilot deployments, per Mordor Intelligence’s IoT Devices Market Report 2026–2031. Process automation leads enterprise IoT adoption at 58%, followed by quality control and energy monitoring at 55% each, per IoT Analytics’ use-case adoption tracking.
IoT Manufacturing Deployment Data
| Metric | Value | Source |
|---|---|---|
| Manufacturing share of global IoT device deployments | 34% | Statista Market Insights |
| Process automation adoption rate | 58% | IoT Analytics |

| Vibration/thermal sensors: downtime reduction | Up to 30% | Mordor Intelligence (pilot documented) |
| IoT revenue in manufacturing (2025 base) | $0.49 trillion → $1.51T by 2030 | Multiple industry sources |
| IIoT market 2026 | $602.87 billion | Precedence Research |
Healthcare IoT (Internet of Medical Things)
Healthcare is the fastest-growing enterprise IoT segment by spending growth rate: 15% CAGR through the forecast period, per research aggregated by IoT Analytics. The IoMT (Internet of Medical Things) market is projected at $257.16 billion by 2026. By 2028 the healthcare IoT market reaches $289.2 billion across multiple research sources.
Medical facilities globally will employ approximately 7.4 million IoT devices by 2026, per Mordor Intelligence’s market report. Remote operation and control accounts for 50% of healthcare IoT deployment; location-based services account for 47%.
The vulnerability picture here is acute: 83% of medical imaging devices operate on unsupported operating systems, per a widely cited industry finding. Healthcare IoT breaches, where connected medical devices are the entry vector, produce costs above $10 million in documented composite analysis.
Medical IoT’s FDA approval rate has accelerated: per Mordor Intelligence’s 2026 IoT Devices market report, approvals for connected health devices rose 40% year-over-year in 2025, shortening product launch cycles and expanding the medical IoT revenue share to 18% of total IoT device application revenue.
Smart Home IoT Statistics
- Global smart home IoT market: $162.8 billion in 2025, reaching $207.0 billion in 2026, per IoT Analytics’ mid-year 2026 Connected Living report.
- Smart home device shipments: 931.1 million units forecast for 2025, per IDC data aggregated by IoT Analytics.
- 45% of U.S. internet households owned at least one smart home device in 2025; 18% owned six or more — per the Institute of Internet Economics’ mid-year 2026 IoT summary.
- Nearly 50% of U.S. households are projected to adopt smart home devices by end-2026.
- Audio and video products (smart TVs, speakers) are present in 56% of equipped smart homes.
- 61% of U.S. households have at least one security camera, totaling approximately 74.9 million homes.
- Smart home ARPU (average revenue per user): $546.50, per SQ Magazine’s IoT 2026 compilation.
The Matter interoperability standard reached version 1.5.1 in 2026, improving camera support and device flexibility, with Matter 1.6 advancing multi-ecosystem device setup. Energy coordination is the emerging smart-home use case: grid-connected smart thermostats and EV chargers now enable time-of-use optimization at household scale.
Smart Cities and IoT
64% of smart city operations globally rely on IoT as a core infrastructure layer, per Global Growth Insights’ 2026 IoT Market report. The global smart cities IoT segment will reach $312 billion in 2026. The smart irrigation sub-segment: $2.3 billion by 2026.
Over 70% of urban infrastructure plans now include smart city components, with more than 63% of government-backed projects integrating IoT for traffic management, energy grids, and waste systems. The smart meter deployment acceleration is quantified: utilities in Texas and Ontario installed 12 million smart meters in 2025 alone, per Mordor Intelligence’s IoT Devices Market Report.
Europe’s smart meter deployment roadmap targets 95% adoption by 2030, requiring NB-IoT and LTE-M connectivity at scale — a procurement signal that is already being priced into module shipment forecasts.
Agricultural IoT
Smart agriculture is set to rise at a 14.39% CAGR during 2026–2031, outpacing the overall smart-home segment, which is slowing as North American and Western European household penetration exceeds one-third, per Mordor Intelligence. The driver is economic: precision irrigation and livestock health monitoring in water-stressed agricultural zones like California’s Central Valley and India’s Punjab. U.S. Farm Bill grants worth $800 million fund sensor-driven irrigation systems, per Mordor Intelligence’s report. In documented field deployments, sensor-led precision agriculture has reduced water use by 20–30%.
The agricultural IoT market was valued at approximately $7 billion in 2025 across industry research estimates.
IoT Data Generation Statistics
Connected IoT devices are the dominant source of non-human data creation. IDC’s foundational Data Age 2025 whitepaper, co-published with Seagate, projected IoT devices would generate 79.4 zettabytes of data in 2025 — a figure cited consistently in the industry. The actual 2025 data-generation figure for the total global datasphere reached approximately 173.4 ZB per updated IDC Global DataSphere data, with IoT devices accounting for a majority of the non-consumer creation component.
The IoT data generation rate that matters operationally: a single offshore oil and gas platform generates 1–2 terabytes per day from its sensor estate. A modern manufacturing facility accumulates tens of petabytes over two years of continuous IoT monitoring. These are not cloud-scale abstractions — they are the numbers that drive edge computing investment.
| IoT Data Metric | Value | Source |
|---|---|---|
| IDC IoT data generation forecast (2025 projection) | 79.4 ZB | IDC / Seagate Data Age 2025 |
| Total global datasphere 2025 (all sources) | ~173.4 ZB | IDC Global DataSphere 2026 |
| Global IoT roaming traffic, 2026 | ~650 PB | IoT Analytics |
| IoT devices as % of mobile data traffic | ~19% | SQ Magazine 2026 IoT Report |
| Devices using <10MB/month (roaming connections) | >80% | IoT Analytics |
| Edge computing deployed in IoT networks | 43% | SQ Magazine 2026 IoT Report |
Over 50% of enterprise-generated data is processed outside centralized data centers in 2026 — reflecting the shift toward edge computing that compresses latency and reduces the cost of transmitting raw sensor streams to the cloud.
IoT Connectivity Technology: The Competitive Landscape
Top IoT Cellular Operators, 2025
| Operator | Share of Global Cellular IoT Connections | Share of Global Cellular IoT Revenue |
|---|---|---|
| China Mobile | 44% | 17% |
| China Telecom | 15% | 6% |
| China Unicom | 15% | 10% |
| Remaining top 5 operators | ~9% combined | ~26% combined |
Source: IoT Analytics Cellular IoT Market Update Spring 2026, April 2026.
China Mobile’s 44% connection share against 17% revenue share tells the real story: Chinese cellular IoT is enormous in volume and compressed in price. The three Chinese carriers together hold 74% of global cellular IoT connections. That concentration is a geopolitical risk factor for Western enterprises whose supply chains pass through Chinese IoT module vendors — Chinese suppliers hold approximately 90% of the cellular IoT module market and 85% of the cellular chipset market, per IoT Analytics’ 2026 market tracking.
IoT Chipset Market
- Cellular IoT chipset revenue: $4.07 billion in 2024, growing 19% YoY, per IoT Analytics’ Wireless IoT Connectivity Chipset Market Report 2025–2030 (published October 2025).
- 2030 forecast: $14.08 billion at 23% CAGR; 5G chipsets alone projected at $9.31 billion by 2030 at a 34% CAGR.
- Top five cellular chipset suppliers in 2025: ASR, Eigencomm, Xinyi, UNISOC, and Qualcomm — with a combined 92% market share.
- HiSilicon is expected to gain rapidly in 2026, particularly in 5G RedCap.
- The cellular IoT module market reached 544 million units in 2025, with revenue of $3.93 billion.
IoT Investment Statistics
Global venture and institutional investment in the IoT ecosystem totals at least $21.3 billion in documented funding. The European Investment Bank leads all tracked IoT investors at $5 billion in total commitments, followed by SoftBank at $3.1 billion and Tencent at $2.3 billion. Singapore’s GIC has committed $2.1 billion; Sequoia Capital and Baidu have each invested $1.6 billion.
IDC’s IoT Spending Guide projected global enterprise IoT investment crossing $1 trillion in 2026 at a 10.4% CAGR. IoT enterprise spending grew only 10% in 2024, its slowest rate in over a decade per IoT Analytics’ State of IoT Spring 2025 report, with hardware the weakest segment while software and cloud-based solutions expanded. India experienced 14% YoY IoT spending growth in 2024 — the brightest regional data point in a year when Europe showed slower-than-expected adoption.
Frequently Asked Questions
How many IoT devices are there in 2026?
At end-2025, there were 21.1 billion connected IoT devices globally, per IoT Analytics’ State of IoT 2025 tracking report. The projected 2026 figure from various sources ranges from 22–22.8 billion, based on continued 13–14% annual growth. By 2030, IoT Analytics forecasts the global connected estate will reach 39 billion devices. The count methodology matters: IoT Analytics excludes PCs, smartphones, and consumer tablets, and counts gateway-aggregated sensor clusters as single devices rather than per-sensor.
What is the IoT market worth in 2026?
The answer depends on scope. Statista’s IoT-specific market measurement — revenue from sensors, modules, platforms, connectivity, and integration services — puts the 2026 figure at $1.18 trillion. Grand View Research’s broader market scope produces $1,596.59 billion for 2025, growing to $3,274.14 billion by 2033. IDC’s enterprise spending tracker forecast total IoT investment crossing $1 trillion in 2026. According to Axis Intelligence Research’s synthesis of these primary-source ranges, the defensible 2026 market estimate is $862.75 billion to $1.18 trillion depending on which revenue scope is applied.
Which country leads the world in IoT adoption?
China leads in connected device volume: Greater China accounts for 6,896 million connected IoT devices as of 2025, representing 32.7% of the global estate, per Transforma Insights data aggregated by Statista. The United States leads in IoT market revenue: Statista projects $420.03 billion in U.S. IoT revenue for 2026, representing roughly 35.6% of global market spend. India is the fastest-growing major market by enterprise IoT spending growth, at 14% YoY in 2024 per IoT Analytics.
What is the biggest security risk in IoT in 2026?
Three findings from Palo Alto Networks’ 2025 Device Security Threat Report define the operational risk: 77.74% of enterprise networks have poor IoT segmentation, allowing connected devices to reach high-value IT systems; 98% of IoT traffic is unencrypted; and 32.5% of devices in enterprise networks operate entirely outside IT visibility. The Aisuru botnet’s 29.7 Tbps DDoS peak in Q3 2025 — documented in Cloudflare’s Q3 2025 DDoS Threat Report — exploited default credentials on IoT devices. Default credentials and flat networks are the two highest-frequency attack prerequisites.
What is Industrial IoT (IIoT) and how large is the market?
Industrial IoT (IIoT) refers to IoT deployments in manufacturing, logistics, energy, and infrastructure environments — sensors on production lines, asset-tracking systems, smart grid meters, and predictive maintenance platforms. The IIoT market is projected at $602.87 billion in 2026, growing to $2,430.21 billion by 2035 at a 16.8% CAGR, per Precedence Research’s June 2026 report. Manufacturing accounts for 34% of all global IoT device deployments. Grand View Research projects IIoT reaching $1,693.44 billion by 2030 at a 23.3% CAGR.
What percentage of IoT devices are at risk?
According to Axis Intelligence Research’s IoT Security Exposure Index™ — calculated by combining Palo Alto Networks’ 77.74% poor-segmentation finding with their 48.2% high-risk IoT connection ratio, applied against IoT Analytics’ 21.1 billion device base — approximately 7.9 billion device-connections, or 37.4% of the total global IoT estate, were operating in enterprise environments combining flat architecture with high-risk traffic profiles as of end-2025. The IoT Analytics data applies to the full estate; the Palo Alto Networks data applies specifically to enterprise network environments, which are a subset of total IoT deployments.
What is the IoT market forecast through 2030?
IoT Analytics projects 39 billion connected devices by 2030, a 13.2% CAGR from 2025. Grand View Research forecasts the broader IoT market at approximately $2.65 trillion by 2030. Statista’s IoT-specific revenue measure projects $1.81 trillion by 2031. IDC forecasts IoT enterprise spending at a 10.4% CAGR through 2027. The cellular IoT segment specifically is expected to reach 9.2 billion connections by 2030, per IoT Analytics’ Cellular IoT Market Update Spring 2026, at a 14.3% CAGR from 2025.
What is the role of 5G in IoT growth?
5G currently represents the premium revenue pool in cellular IoT while NB-IoT and LTE Cat.1 bis dominate connection volumes. IoT Analytics’ October 2025 Wireless IoT Connectivity Chipset Market Report projects 5G IoT chipset revenue reaching $9.31 billion by 2030 at a 34% CAGR — the fastest-growing technology segment in the cellular IoT stack. 5G RedCap rollouts reached 34 operators in 24 countries in 2025, targeting mid-tier bandwidth applications that need more capability than NB-IoT can deliver. Private 5G deployments in China are already proving performance at manufacturing scale.
Is the IoT market still growing despite economic headwinds?
Yes, but the growth moderated. IoT enterprise spending grew 10% in 2024 — the lowest rate in over a decade — per IoT Analytics’ State of IoT Spring 2025 report, with hardware the weakest segment. Despite that, the global connected device count still grew 12% in 2024 to 18.5 billion, and accelerated to 14% growth in 2025. The deceleration is in enterprise spending; the device count continues to climb because consumer IoT, smart metering, and automotive connectivity operate on procurement cycles independent of enterprise budget cycles.
Methodology
Axis Intelligence Research assembled this dataset from named primary sources: IoT Analytics (device count tracking, cellular market data, connectivity technology breakdowns), Palo Alto Networks (enterprise device security, OT research), Grand View Research (IoT market size), Mordor Intelligence (IoT devices segment), Precedence Research (IIoT), Statista Market Insights (revenue and regional breakdown), IDC (data generation and enterprise spending), and Cloudflare (DDoS threat data). Every external figure is dated to its source publication.
The IoT Security Exposure Index™ is an original Axis Intelligence Research metric derived from cross-referencing two independent primary-source datasets (Palo Alto Networks 2025 Device Security Threat Report and IoT Analytics State of IoT 2025). The calculation uses published percentage figures applied to the IoT Analytics device-count base. Neither input source makes this composite claim, which makes it original to Axis Intelligence Research.
IoT market size variance: Multiple figures appear throughout this article because “IoT market size” is not a single construct. Sources measuring only IoT-specific component revenue produce different numbers than those measuring total solution and services revenue. Where possible, Axis Intelligence Research specifies the scope of each figure. Readers building financial models should use a single source’s methodology consistently rather than mixing figures across reports.
Data freshness: Device count data reflects 2025 full-year figures as the latest complete annual dataset. Revenue projections are 2026 forecasts from reports published between October 2025 and June 2026. Cellular connectivity data reflects IoT Analytics’ Q1 2026 publication. All figures older than 12 months are flagged in the source column.
About This Dataset
This article will be revised when a primary source listed above publishes a materially updated figure — specifically IoT Analytics’ next device-count update, the next Grand View Research IoT market report, or a major documented IoT-vector breach that shifts the security cost data.
