Predicting the Future of IoT: Market Size, Growth, and Key Opportunities

When I was a child, I delighted in building plastic model cars and planes from kits that demanded patience, precision, and a bit of imagination. Forty years later, I find myself studying a technology that similarly brings disparate components together—this time, electronics and software—to create fully connected, end‑to‑end solutions. In the 21st century, the Internet of Things (IoT) is the modern equivalent of those childhood models, but on a global, industrial scale.

MachNation, a leading IoT research firm, has developed a detailed forecast that breaks down the industry into six layers of the IoT stack. The analysis illuminates where revenue is generated and how each layer will evolve over the next decade.

MachNation’s IoT Forecast Breaks Down Six Key Layers

1. IoT devices – the edge hardware that collects data.
2. IoT communications services – wide‑area networks that transport data from devices to systems.
3. IoT platforms – core layers for data ingestion, device management, and analytics.
4. IoT application development – designing, testing, and building solutions.
5. IoT integration services – stitching together the diverse technology pieces.
6. IoT vertical services – industry‑specific analytics and services that wrap around the core solution.

Key Forecast Findings from MachNation

IoT Growth is Fueling Opportunity in Both Emerging and Developed Markets

MachNation projects worldwide IoT revenue to jump from USD 98 billion in 2016 to a staggering USD 987 billion by 2025, reflecting a compound annual growth rate (CAGR) of 29%. While emerging regions accounted for 22% of total revenue in 2016, they are expected to represent 41% by 2025—an indicator of the rapid device adoption in these markets. Notably, per‑unit revenue in emerging regions will still trail that of developed markets by 35%, underscoring the price sensitivity and scale of opportunity in those areas.

Integration Services Dominate Today’s Custom IoT Solutions

More than one‑third of total IoT revenue in 2016 is derived from integration services, a reflection of the high degree of customization required to assemble viable solutions. Enterprises pay significant time and money to ensure that devices, platforms, and applications work seamlessly together. Vendors that can deliver pre‑integrated, tested end‑to‑end solutions are setting new industry benchmarks.

Productized Vertical Solutions Will Drive Growth by 2025

By 2025, vertical services are projected to contribute almost 40% of global IoT revenue. These offerings—combining industry‑specific applications and ancillary services—will span transportation, heavy industry, construction, healthcare, building automation, energy, security, and smart‑city sectors. Parallel growth in IoT platform revenue is also anticipated.

Rapid Expansion of IoT Platform Revenue

The segment covering application enablement and device management is among the fastest‑growing. In 2016, this category generated USD 1.1 billion, rising to USD 83.4 billion by 2025 at a CAGR of 62%. Effective device‑to‑application data transfer is essential for enterprise adoption, and MachNation’s own IoT Application Enablement Scorecard provides guidance on selecting high‑quality vendors.

Conclusion

Today’s heavily customized IoT deployments—requiring extensive integration—are paving the way for tomorrow’s productized solutions. This transition will lower deployment costs, expand adoption, and allow smaller enterprises to participate in the IoT economy.

Just as a child enjoys the satisfaction of a completed plastic model, businesses now seek pre‑integrated, proven IoT solutions for speed, safety, and cost efficiency.
