Factors contributing to slower IoT market growth in 2024
Economic concerns weigh heavily on spending growth. Throughout 2023 and into 2024, economic concerns remained the top topic of CEOs during earnings calls. These concerns have generally led to reduced corporate spending, including for IoT.
Hardware spending is dragging the overall enterprise IoT spending growth rate down. Corporate curtailment of spending has hit IoT hardware the hardest. Out of the entire IoT tech stack—security, services, software, and hardware—hardware is likely to have the lowest growth rate in 2024 at 5%, according to the Global IoT Enterprise Spending dashboard. Specifically, the computers, controllers, and gateways segment is expected to experience a drop in actual enterprise IoT spending. One of the reasons is the high inventory levels that customers stockpiled in the last quarters.
Hardware companies express doubt about growth expectations in 2024. During individual interviews with over 300 exhibitors at Hannover Messe 2024, vendors with a heavy hardware footprint (e.g., large industrial automation suppliers) expressed caution when discussing their 2024 business outlooks—some citing customer inventory surplus and limited demand, which can lead to sales dips. Additionally, in May 2024, the CEOs of Siemens and Rockwell Automation—two leaders in this area—highlighted the muted industrial demands and high stock levels (particularly in China) during their Q2 earnings calls.
IoT market drivers in 2024 and beyond
IoT has a strong impact on the bottom line. According to IoT Analytics’ upcoming IoT Use Case Adoption Report 2024, enterprise IoT investments are overwhelmingly paying off—a finding likely to drive enterprise IoT market size growth in the coming years. Findings from the ongoing research show that the share of companies that report a positive ROI from IoT adoption has increased, and boardrooms are convinced about IoT’s positive impact.
Regional market drivers
China, India, and the US expected to drive market growth. In 2024, companies in China, India, and the US are expected to grow their IoT spending by 17%, 14%, and 13%, respectively. IoT Analytics forecasts higher growth for these countries in the coming years, with China and the US expected to exceed the YoY global growth average through the end of the decade and India to exceed until 2028.
Vertical market drivers
Automotive and process manufacturers to consistently outpace enterprise IoT spending growth through 2030. The dashboard projects automotive manufacturers to grow their enterprise IoT spending by 14% in 2024 and 18% in 2025. Through the decade’s end, the difference between their enterprise IoT spending growth rate and the global average is predicted to remain between 1 and 3 percentage points higher.
The automotive sector is undergoing significant change towards electric vehicles (EVs), autonomous driving, and software-defined vehicles. This transition requires substantial investment in IoT for vehicle connectivity, real-time data processing, and integration of advanced driver-assistance systems (ADAS). Moreover, car manufacturers must redesign entire factories from producing vehicles with combustion engines to putting out smart electric vehicles. As the CEO of Renault, Luca de Meo, put it in the company’s Q1 2024 earnings call, “Transforming our industrial base puts us on track to reduce production costs by 30% for ICE and hybrid cars and by 50% for EVs by 2027. For example, deploying predictive maintenance AI tools resulted this year in a €270 million saving on energy and maintenance.”
Meanwhile, process manufacturers—those that utilize chemical, physical, or compositional changes to convert raw materials or feedstock into products—are expected to grow their enterprise IoT spending by 13% in 2024 and remain 1 to 2 percentage points above the YoY growth averages through 2030. Process manufacturers use IoT with the intent to enhance operational efficiency, improve safety, foster better communication, modernize operations, achieve scalability, and provide accessible data for informed decision-making. Examples of heavy IoT investment in this sector include Dow Chemical’s deployment of private LTE networks to modernize operations and enhance efficiency across their extensive Freeport manufacturing site. Such initiatives aim to improve operational efficiency, enhance worker safety, and streamline communication and collaboration.
Technology market drivers
IoT software expected to see strong growth through the end of the decade. All three subcategories of the IoT software segment—platforms (including platforms as a service), infrastructure as a service (IaaS), and applications (including software as a service)—are set to expand strongly in the next few years, following only a slight growth dip in 2024. IaaS and applications both appear set for continued 20%+ CAGRs.
AI integration set to drive enterprise IoT software spending. The integration of IoT with other emerging technologies, such as AI and machine learning, offers advanced features like predictive analytics, real-time monitoring, and AI-driven insights. That has the potential to enhance the appeal and utility of IoT software solutions. Based on IoT Analytics’ interviews with exhibitors at Hannover Messe 2024, and in contrast with their hardware counterparts, software vendors have a positive business outlook in 2024, largely driven by the excitement surrounding AI products and their growing adoption. Major IT vendors such as Microsoft, Amazon, and SAP, as well as systems integrators like Avanade and Cognizant, highlighted a strong focus on new AI and data-related projects.
Use case market drivers
IoT-based process automation and asset/plant/operations performance optimization are top priorities for enterprises. The use cases that are expected to see the highest spending growth are IoT-based process automation and asset/plant/operations performance optimization. Both are forecasted to see the highest levels of growth in 2024 and 2025 and exceed the average YoY global growth rates through 2030. And rightly so, since the investment usually pays off. One finding of the upcoming IoT Use Case Adoption Report 2024 is that only 2% of end-users who invest in an IoT-based process automation report a negative/zero ROI.
