IDC expects worldwide IoT spending will maintain a double-digit annual growth rate throughout the 2017-2022 forecast period and surpass the USD1 trillion mark in 2022.
The industries that are forecast to spend the most on IoT solutions in 2019 are discrete manufacturing (USD119 billion), process manufacturing (USD78 billion), transportation (USD71 billion), and utilities (USD61 billion). IoT spending among manufacturers will be largely focused on solutions that support manufacturing operations and production asset management. In transportation, more than half of IoT spending will go toward freight monitoring, followed by fleet management. IoT spending in the utilities industry will be dominated by smart grids for electricity, gas, and water. The industries that will see the fastest compound annual growth rates (CAGR) over the five-year forecast period are insurance (17.1%), federal/central government (16.1%), and healthcare (15.4%).
The IoT use cases that will see the greatest levels of investment in 2019 are driven by the industry spending leaders: Manufacturing operations (USD100 billion), production asset management (USD44.2 billion), smart home (USD44.1 billion), and freight monitoring (USD41.7 billion). The IoT use cases that are expected to deliver the fastest spending growth over the 2017-2022 forecast period provide a picture of where other industries are making their IoT investments. These include airport facility automation (transportation), electric vehicle charging (utilities), agriculture field monitoring (resource), bedside telemetry (healthcare), and in-store contextualized marketing (retail).
IoT services will be the largest technology category in 2019 with USD258 billion going toward traditional IT and installation services as well as non-traditional device and operational services. Hardware spending will be close behind at USD250 billion led by more than USD200 billion in module/sensor purchases. IoT software spending will total USD154 billion in 2019 and will see the fastest growth over the five-year forecast period with a CAGR of 16.6%. Services spending will also grow faster than overall IoT spending with a CAGR of 14.2%. IoT connectivity spending will total USD83 billion in 2019.
