IoT in Smart Cities Market - Global Forecast 2025-2030

The IoT in Smart Cities Market size was estimated at USD 182.07 billion in 2024 and expected to reach USD 214.11 billion in 2025, at a CAGR 17.12% to reach USD 469.96 billion by 2030.

The advent of the Internet of Things (IoT) has fundamentally altered the way urban environments operate, ushering in a new era of connected intelligence that underpins efficient public services and infrastructure management. By embedding sensors, gateways and actuators throughout city systems, municipalities can gather real-time data on everything from traffic flows to air quality, enabling more responsive governance and a higher quality of life. This integration is further magnified by advances in network technologies and edge computing, which reduce latency and empower localized decision-making at the device level, ensuring that critical alerts and automated controls occur seamlessly at the point of need.

The contemporary smart city landscape is undergoing a profound transformation fueled by breakthroughs in connectivity, analytics and artificial intelligence. The rollout of 5G-Advanced networks offers unprecedented data rates and ultra-reliable low-latency communications that support immersive applications like autonomous transit and real-time public safety monitoring. Concurrently, the convergence of AI and IoT-often referred to as AIoT-enables predictive maintenance and proactive service optimization, allowing city administrators to anticipate infrastructure failures and allocate resources dynamically. Moreover, edge computing has emerged as a pivotal enabler for decentralized data processing, ensuring that mission-critical functions such as traffic signal adjustments and emergency response analytics are executed without dependence on distant cloud servers.

In 2025, the U.S. trade policy environment has exerted a notable cumulative effect on IoT device supply chains, cost structures and deployment timelines within smart city projects. At the start of the year, semiconductor components critical to sensors and controllers faced a tariff rate increase from 25 percent to 50 percent under Section 301 of the Trade Act, impacting products classified under HTS headings 8541 and 8542 and elevating procurement costs for integrated circuits used in connected traffic and environmental monitoring devices. Shortly thereafter, in early April, the administration imposed Reciprocal Tariffs that added to existing Section 301 and IEEPA levies on China-origin goods, resulting in combined duties as high as 170 percent on key hardware imports and compelling many integrators to reassess supplier strategies and localize component sourcing where feasible. Although a diplomatic agreement in mid-May reduced Reciprocal Tariffs on Chinese-origin products to 10 percent by May 14, the retention of core Section 301 and Section 232 measures has sustained elevated barriers for specialized IoT modules and advanced sensor technologies. Collectively, these shifts have prolonged lead times, injected cost volatility and accelerated the diversification of manufacturing footprints beyond traditional hubs.

The IoT market in smart cities can be dissected through multiple analytical lenses, each revealing unique value drivers and strategic imperatives. From a component perspective, hardware segments such as actuators, gateways and a variety of sensors-environmental, motion and temperature-form the foundation of connectivity and environmental awareness, while services split between managed and professional offerings enable live operation and bespoke system integration. Software capabilities center on platforms and advanced analytics, ranging from descriptive insights to predictive models that forecast maintenance windows and resource demand. When viewed by communication technology, solutions traverse cellular networks (including 5G and LTE), LPWAN protocols like LoRaWAN, NB-IoT and Sigfox, as well as WLAN standards embodied by Bluetooth and Wi-Fi. Application domains extend across energy management, public safety, smart lighting, parking, traffic management and waste systems. Meanwhile, end-use sectors such as government, healthcare, transportation and utilities underscore the diverse stakeholders driving IoT investments. Finally, deployment modes oscillate between cloud and on-premise architectures, reflecting varying priorities around latency, scalability and data sovereignty.
