30+ IoT Statistics, Connected Devices & Market Size Data (2026)

The Internet of Things stopped being a buzzword sometime around the pandemic and quietly turned into infrastructure. In 2026, IoT is the layer that lets a factory in Stuttgart fine-tune a torque wrench in real time, a hospital in Boston monitor a heart-failure patient from her living room, and an Amazon Echo in a London kitchen reorder dishwasher tabs before the cupboard is empty. The headline number is enormous and growing fast — IoT Analytics counts 21.1 billion connected devices at the end of 2025, on a track that points to roughly 39 billion by 2030 — but the more interesting story is the one happening at the seam where IoT, edge compute, 5G and generative AI all start to converge.

The market signals back that story up. Statista pegs worldwide IoT market revenue at US$1.18 trillion in 2026. Ericsson's November 2025 Mobility Report counts 4.5 billion cellular IoT connections globally and forecasts that figure to approach 8 billion by 2031. GSMA Intelligence projects total IoT connections of more than 38 billion by 2030, with enterprises owning 60% of the base. Below are 30+ statistics we could verify against their primary sources, organised into the themes that matter most for any business, household, or shopper navigating a world where every appliance, vehicle and wearable is starting to talk back.
