Smart Cities Market Projected to Reach $1,445.6 Billion by 2030

The global smart cities market is forecast to grow from $699.7 billion in 2025 to $1,445.6 billion by 2030, representing a compound annual growth rate of 15.6%. This expansion is driven by rapid urbanization, environmental sustainability goals, and the integration of advanced technologies like IoT sensors and AI analytics to optimize resource use. The sector's growth reflects a shift toward data-driven urban management across transportation, utilities, and public services to improve the quality of life for residents.

According to a new report from MarketsandMarkets, the smart cities sector is poised for significant expansion, nearly doubling its valuation over a five-year period. The growth is underpinned by the deployment of connected infrastructure and smart grids designed to enhance energy efficiency and reduce traffic congestion. Key applications include smart waste management to minimize landfill use and intelligent transport systems aimed at lowering emissions. These solutions prioritize environmental conservation while fostering resilient urban ecosystems capable of real-time monitoring and efficient utility management.

Within the market, commercial smart buildings are expected to hold the largest share, fueled by high adoption in retail spaces and corporate office parks. These facilities utilize automated building management systems (BMS) to control HVAC and lighting, alongside AI-driven space optimization and IoT sensors for environmental monitoring. Meanwhile, passenger information management (PIM) is slated to be the fastest-growing segment in smart transportation. PIM systems leverage real-time data and AI to provide transit updates via mobile apps and digital signage, which encourages public transport use and streamlines transit networks.

The Asia Pacific region is projected to register the highest CAGR, driven by massive population increases in India, China, and Southeast Asia. Specific government initiatives, such as India’s Smart Cities Mission and China’s New Urbanization Plan, are accelerating digital infrastructure development alongside the expansion of 5G networks. Major industry vendors, including Cisco, IBM, Siemens, Microsoft, Hitachi, Schneider Electric, Huawei, NEC Corporation, and ABB, are actively pursuing growth through collaborations, acquisitions, and product launches to capture market share in this evolving global landscape.
