About these statistics. IoT market data varies significantly between analyst firms due to differences in scope, methodology and what counts as a “connected device”. Where figures differ between sources, we present a range rather than selecting a single number. We cite the analyst or publisher for every figure on this page and across all linked statistics pages. We do not source figures from press releases, vendor white papers or secondary aggregators without verification against primary reports. All pages are reviewed and updated quarterly. Last reviewed: June 2026.
This hub is updated quarterly. Individual statistics pages are updated monthly where new primary data is available. Next scheduled review: September 2026.

Frequently asked questions

How many IoT devices are there in 2026?
Estimates vary by methodology. IoT Analytics reports approximately 21.9 billion connected IoT devices globally in 2026, up from 18.5 billion in 2024. Statista and Transforma Insights place the figure closer to 19-20 billion for 2025, rising to over 40 billion by 2034. The higher figures from some sources include all connected endpoints; the lower figures exclude consumer devices such as smartphones and tablets. See our connected devices statistics page for a full breakdown.
How big is the global IoT market in 2026?
The global IoT market in 2026 is estimated at between $547 billion (MarketsandMarkets, narrower scope) and $863 billion (Fortune Business Insights, broader scope including services). SQ Magazine places the 2026 figure at $862.75 billion. The variation reflects differences in whether hardware, software, connectivity and services are all included. Most forecasts project the market crossing $1 trillion by 2027-2028.
What is the fastest-growing segment of the IoT market?
Healthcare IoT is growing at approximately 32.5% CAGR – the fastest among major industry verticals. Within connectivity technology, 5G IoT chipsets are growing fastest at a 34% CAGR through 2030. The sustainable energy sub-segment also posts a 30.4% CAGR forecast through 2032.
How many cellular IoT connections are there?
According to the Ericsson Mobility Report, total cellular IoT connections reached approximately 4.5 billion at the end of 2025. Of these, 2.6 billion were Broadband and Critical IoT connections (4G/5G). The forecast is for cellular IoT to approach 8 billion connections by 2030-2031, with Broadband IoT becoming the majority connection type.
How often are these statistics updated?
The hub page is reviewed quarterly. Individual topic pages are updated when new primary analyst data is published – typically monthly for fast-moving segments such as cybersecurity and cellular connectivity. Each page displays its last-reviewed date and primary sources.
