IDC predicts that global spending on Internet of Things (IoT) will reach $737 billion in 2016 and rise to $1.29 trillion in 2020 at a CAGR of 15.6% over the 2015-2020 forecast period.
The increase will be fuelled by organizations as they invest in the hardware, software, services, and connectivity that enable the IoT.
The industries which are expected make the largest IoT investments in 2016 are Manufacturing ($178 billion), Transportation ($78 billion), and Utilities ($69 billion). Consumer IoT purchases, the fourth largest market segment in 2016, will become the third largest segment by 2020.
Meanwhile, Cross-Industry IoT investments, which represent use cases common to all industries, such as connected vehicles and smart buildings, will rank among the top segments throughout the five-year forecast. The industries that will see the fastest spending growth are Insurance, Consumer, Healthcare, and Retail.
“A fairly close relationship exists between high growth IoT use cases in consumer product and service oriented verticals like retail, insurance, and healthcare,” said Marcus Torchia, research manager, IoT, with IDC’s Customer Insights and Analysis team. “In some cases, these are green field opportunities with tremendous room to run. In other verticals, like manufacturing and transportation, large market size and more moderate growth rate use cases characterize these verticals. As a whole, the IoT opportunity is a diverse developing market place for vendors and end users alike.”
From a technology perspective, hardware will remain the largest spending category throughout the forecast, followed by services, software, and connectivity. And while hardware spending will nearly double over the five-year timeframe, it represents the slowest growing IoT technology group. Software and services spending will both grow faster than hardware and connectivity. Hardware spending will approach $400 billion by 2020. Modules and sensors, that connect end points to networks, will dominate hardware purchases, while application software will represent more than half of all IoT software investments.
The regions which will lead the IoT spending includes Asia/Pacific (excluding Japan)(APeJ)) followed by the United States, Western Europe, and Japan.
Nearly a third of IoT purchases in APeJ will be made by the manufacturing industry, while Utilities and Transportation will change places as the second and third largest IoT industries by the end of the forecast. In the United States, Manufacturing will be the industry with the largest IoT investments throughout the forecast but with a lower share (roughly 15%) of total spending. In Western Europe, Consumer IoT spending will overtake Transportation and Utilities to become the second largest IoT industry in 2020.
