The silent, digital nervous system of our planet is growing at an astonishing rate.
Imagine a typical morning: your smart thermostat has already adjusted the temperature to your waking preference, your wearable health monitor is sending a quiet status update to your doctor, and the city’s traffic sensors are dynamically optimizing signal times based on real-time congestion data. This isn’t a scene from a sci-fi movie; it’s the reality being built today by the Internet of Things (IoT).
How many connected devices will exist by 2030?
By the end of 2024, there will be 18.8 billion connected IoT devices globally. Fueled by advancements in AI and the expansion of 5G networks, this number is projected to double, reaching approximately 40 billion by 2030. This represents a massive digital transformation that is quietly reshaping our world, from industrial factories to our own living rooms.
Why the Number of IoT Devices Is Exploding
The staggering growth in connected devices isn’t happening by accident. It’s being driven by a powerful convergence of technological, economic, and societal factors.
The AI and Analytics Engine: IoT is no longer just about connecting devices; it’s about making them intelligent. Artificial Intelligence is at the forefront of corporate strategy, with CEOs discussing it more than any other tech topic in earnings calls.
The integration of AI, including generative AI and edge AI, allows the vast amounts of data generated by IoT sensors to be processed and acted upon in real-time. For a deeper dive into how AI is transforming industrial efficiency, check out how industrial AI agents are slashing energy costs in manufacturing.
This enables predictive maintenance in factories, personalized health insights from wearables, and smarter energy grids. As one executive from AMD noted, “We stand on the brink of an era where edge AI will reshape our world in a profound way.” For more on how edge AI is driving real-time intelligence, explore this detailed analysis on edge AI versus cloud AI.
The Connectivity Backbone of 5G: You can’t have billions of devices talking to each other without a robust, high-speed network. The rollout of 5G technology is a critical enabler, providing the high data transfer rates, increased capacity, and ultra-low latency required for advanced applications like autonomous vehicles and remote surgery.
A key development in 2024 has been the launch of 5G RedCap (Reduced Capability), which offers a cost-effective way to connect a massive number of medium-complexity devices, such as those for high-quality video surveillance. By 2030, cellular IoT connections alone are forecast to surpass 7 billion.

The Rise of Hyperconnected Ecosystems: IoT is evolving into what IBM terms the “Economy of Things” (EoT). In this new paradigm, IoT devices become digital assets that can autonomously share, monetize, and transact value.
Think of an electric fleet truck that can automatically pay for its own charging at a smart station without driver intervention. This creates new, fluid value chains that span across entire industries, dramatically increasing the utility and adoption of connected devices. For insights into how these ecosystems are driving market growth, see the rise of the industrial AI data marketplace.
