Report Overview

In 2025, the Global Smart City Market was valued at USD 1.4 trillion. The market is projected to grow at a CAGR of 21.6% during 2026–2035, reaching approximately USD 10.2 trillion by 2035. North America dominated the global market in 2025, accounting for more than 22.0% of the total market share and generating approximately USD 384.3 billion in revenue.

Growth is mainly supported by rapid urbanization, rising infrastructure spending, and stronger government focus on digital public services. In 2018, UN DESA reported that 55% of the global population lived in urban areas and estimated that this share would rise to 68% by 2050. This shift will add nearly 2.5 billion urban residents, mainly across Asia and Africa, creating significant demand for modern transport, energy, water, waste management, housing, and public safety systems.

Urban infrastructure investment is also increasing rapidly. Annual physical capital investment in cities was expected to rise from around USD 10 trillion to more than USD 20 trillion by 2025. Total urban infrastructure requirements, including buildings, utilities, and transport networks, are estimated at approximately USD 80–97 trillion by 2040. If only 10–15% of this spending is directed toward connected and intelligent systems, the smart city market could reasonably exceed USD 10 trillion by 2035.

North America is supported by early adoption of 5G, IoT, smart grids, and data-based city management. Urbanization in several advanced economies is expected to exceed 80% by 2050, while infrastructure spending commonly represents 2–6% of GDP. As the global urban population increases from 4.2 billion to approximately 6.7 billion by 2050, demand for smart mobility, utilities, governance, and public services will continue to strengthen.

By Application

Smart utilities held the leading 29.5% share, as cities depend on reliable electricity, water, and waste services. In 2024, global electricity access reached about 92%, but 655 million people still lacked power, while 2.1 billion lacked safely managed drinking water and 3.4 billion lacked safely managed sanitation. These gaps are encouraging governments to invest in smart grids, digital water networks, automated controls, and metering.

WHO and UNICEF data show that safely managed sanitation coverage increased from 48% in 2015 to around 58–59% in 2024, helping more than 900 million people gain improved services. Smart meter deployments are expected to reach nearly 3.9 billion units worldwide by 2035, supporting demand for sensors, analytics, and utility management platforms.

Smart public safety is the fastest-growing device segment as urban density increases exposure to crime, road accidents, disasters, and health emergencies. More than 55% of the global population lives in urban areas, while public order and safety spending can represent 1–2% of GDP in some high-income economies.

By Component

Hardware held a leading 54% share of the smart city component market because every digital urban service depends on physical equipment such as sensors, cameras, smart meters, controllers, and communication devices. According to the International Energy Agency, hundreds of millions of residential smart meters had already been installed worldwide by 2021, with deployment programs continuing across major economies.

Software is the fastest-growing smart city component because cities increasingly use data, automation, and artificial intelligence to improve the performance of existing infrastructure. As the number of connected sensors and meters reaches billions, municipalities require advanced platforms to process information and support real-time decisions. Software enables predictive maintenance, dynamic pricing, traffic optimization, and digital citizen services without replacing installed hardware.

Global infrastructure investment requirements are estimated at nearly USD 94 trillion between 2016 and 2040, with around 56% associated with urban areas.

Smart lighting is the fastest-growing device segment because streetlights are widely installed, energy-intensive, and relatively easy to modernize. Outdoor lighting can represent around 10–20% of municipal electricity consumption, while large cities may operate hundreds of thousands of lighting units. Replacing conventional lamps with LEDs and connected controllers can reduce energy use by up to 50–70%.

By Smart Utilities

Energy management held the leading 28% share of smart utilities because cities consume large amounts of electricity and require better control over demand, losses, and renewable energy integration. Cities account for around 75% of global energy use and nearly 70% of greenhouse gas emissions, while buildings and industries consume more than 90% of global electricity.

In 2019, worldwide final electricity consumption reached approximately 22,848 TWh. Electricity’s share of final energy demand is expected to rise from about 20% today to more than 50% by 2050 under net-zero scenarios. Smart meters, demand-response tools, and building energy platforms help utilities monitor millions of connections, forecast peak demand, and shift loads automatically.

Waste management is the fastest-growing smart utility segment as global waste volumes continue to increase. Municipal solid waste generation reached about 2.6 billion tonnes in 2022 and could rise by 50% to 3.8 billion tonnes by 2050. Waste volumes may increase by more than 90–120% across Sub-Saharan Africa and South Asia.

Cities are therefore adopting smart bins, digital tracking, and route-optimization systems. With urban waste expected to increase by over 1 billion tonnes between 2022 and 2050, demand for connected waste-monitoring devices will expand rapidly.

By Smart Transportation

Intelligent transportation systems held the leading 30% share of smart transportation because growing vehicle fleets and traffic congestion require real-time monitoring and control. Global motor vehicle production exceeded 90 million units in 2023, supporting more than 1.4 billion vehicles in use worldwide. Private cars account for over half of urban passenger-kilometres, generate around 75% of urban passenger transport emissions, and receive more than 95% of road space in many cities.

Severe congestion can cost economies up to 1% of GDP, while commuters in major U.S. and European cities lose dozens of hours each year in traffic. Adaptive signals, connected public transport, centralized control centres, and incident-management systems improve traffic flow. Even modest reductions in delays across millions of daily journeys can generate billions of dollars in economic and fuel savings.

Parking management is the fastest-growing device segment because inefficient parking increases congestion, emissions, and pressure on valuable urban land. In many low- and middle-income cities, over 95% of road space, including on-street parking, is allocated to private vehicles. Smart parking sensors, connected meters, digital payments, dynamic pricing, and guidance applications provide real-time space information.

By Smart Healthcare

Medical devices held the leading 55.5% share of smart healthcare because diagnosis, monitoring, and treatment depend on physical equipment used in hospitals, clinics, ambulances, and homes. Global health spending reached USD 9.8 trillion in 2021, equal to 10.3% of world GDP, while governments contributed more than USD 6.2 trillion. A major part of healthcare capital spending supports imaging systems, ventilators, infusion pumps, surgical equipment, and bedside monitors.

In high-income countries, average healthcare expenditure is around USD 4,000 per person each year. Population ageing and urban growth are increasing demand for connected devices that provide real-time monitoring, automated alerts, and remote diagnosis. These systems improve patient safety, staff productivity, and treatment capacity, supporting continued investment in medical hardware.

Systems and software are the fastest-growing smart healthcare segment because they convert data from millions of medical devices and patient interactions into useful clinical information. Healthcare represents around 10% of global GDP, and a rising portion is being directed toward electronic health records, telemedicine, analytics, and clinical decision-support tools.

By End-User

Government and municipal bodies held the leading 48% share of smart city end-user demand because they manage essential urban services and control major infrastructure and technology budgets. Global infrastructure investment requirements are estimated at around USD 94 trillion between 2016 and 2040, with more than 50% linked to transport, energy, water, and public facilities.

In the United States, public infrastructure spending reached approximately USD 625.8 billion in 2023, and nearly 80% was funded by state and local governments. These authorities purchase and operate smart traffic systems, connected lighting, public safety networks, digital utilities, and citizen-service platforms.

Transportation and logistics operators are the fastest-growing smart city end-user segment because rising passenger and freight volumes require better real-time coordination. E-commerce growth, rapid deliveries, and expanding city populations are placing greater pressure on roads, depots, and curb space.

Geopolitical Impact Analysis

Geopolitical tensions are significantly affecting the cost and delivery schedules of important smart city equipment, including IoT devices, grid systems, smart lighting, surveillance cameras, sensors, and networking products. Tariff measures tracked by the WTO and IMF show that effective duties on several information and communication technology goods have increased to around 10–25% under Section 301 and related trade actions. These tariffs directly raise the import cost of semiconductors, sensors, and communication equipment used in connected urban infrastructure.

Critical mineral supply risks are also creating uncertainty. The International Energy Agency reported that lithium prices increased by nearly eightfold during 2021–2022 before falling by more than 80% after 2023. Prices for graphite, cobalt, and nickel declined by around 10–20% in 2024 from earlier peaks. Such volatility makes pricing and capital planning more difficult for electric-bus fleets, energy storage projects, smart grids, and backup power systems.

Shipping disruptions are adding further pressure. According to UNCTAD, the Red Sea crisis forced many vessels operating between Asia and Europe to travel around the Cape of Good Hope. This diversion added approximately 12 sailing days, increased transit times by nearly 30%, and reduced effective global container capacity by an estimated 9%. Container rates on the Shanghai–Rotterdam route doubled, while prices on the Shanghai–Genoa route increased by 350% between 1 December and 1 February.

For smart city projects dependent on Asian electronics, cameras, and LED equipment, these conditions can increase landed hardware costs by 15–30% and extend project schedules by several weeks. Municipalities and system integrators are therefore adopting nearshoring, multi-sourcing, and phased deployment strategies to control budget and delivery risks.

Regional Analysis

North America held the leading position in the global smart city market in 2025, accounting for an estimated 22.0% share and approximately USD 384.3 billion in revenue.

Market Dynamics

Drivers

Urban infrastructure digitalization mandates

Urban infrastructure digitalization mandates could add approximately +4.0% to the baseline Smart City Market CAGR by turning traditional transport, energy, water, and building projects into continuous technology-purchasing programs. Cities represent nearly 56% of global infrastructure investment requirements through 2040, while annual infrastructure spending is estimated at around 3–4% of global GDP.

A growing portion of this expenditure is being directed toward digitally enabled assets, including sensor-equipped roads, automated power grids, connected water networks, and intelligent buildings. The expected addition of approximately 2.5 billion urban residents between 2020 and 2050 will further require municipalities to expand infrastructure while meeting climate, efficiency, and resilience targets.

Multi-year service contracts can increase recurring revenue per installed asset by an estimated 10–20%. This combination of mandatory smart features, large public infrastructure budgets, and service-based contracts supports faster and more stable growth across smart utilities, transportation, buildings, and governance platforms compared with conventional infrastructure investment.

Restraints

High sovereign borrowing costs

High sovereign borrowing costs could reduce the Smart City Market’s baseline CAGR by approximately -3.5%, as governments face greater difficulty financing large urban technology projects. Sovereign bond yields in many emerging markets increased from nearly 3–4% during the mid-2010s to around 7–9% after 2022, while several frontier economies now pay double-digit rates on new debt.

Interest payments also consume more than 10% of government revenue in a growing number of countries, leaving less funding available for smart grids, intelligent transport systems, digital utilities, and integrated city platforms.

Municipal governments often depend on central transfers, government guarantees, or public borrowing to fund infrastructure. When national budgets tighten, local capital expenditure can decline by 10–20% year on year in financially stressed markets.

Challenges

Critical digital skills gap

The critical digital skills gap imposes around -3.0% friction on potential CAGR by limiting how fast cities can design, deploy, and operate complex smart systems, even when funding exists. Per ILO labour statistics, global shortages of ICT professionals exceeded 4 million roles in 2025, with demand for data engineers, cybersecurity specialists, and cloud architects growing at more than 10% annually.

OECD skills surveys show that fewer than 30% of municipal employees in many member countries report advanced competence in data analytics or digital project management, despite rapid adoption targets for e-government and smart infrastructure. According to World Bank urban governance assessments, capability constraints are a leading reason why large cities under-execute approved digital budgets, sometimes achieving only 60–70% of planned disbursements in early program years.

Strategically, this forces reliance on external systems integrators, increases project overheads by an estimated 5–10%, and extends deployment timelines well beyond initial plans. Private vendors must invest heavily in training, managed services, and simplified tooling to compensate.

Opportunities

Outcome-based smart service contracts

In 2022, 57% of the global population lived in urban areas, with the share projected to reach 68% by 2050. More than 70% of EU residents already live in cities, which generate 23% of transport-related emissions. Residents travel an average of 27 kilometres per day for 80 minutes, while ride-hailing is used by 23% and ride-sharing by 12%.

Buildings represented around 30% of global energy demand in 2024, with residential properties accounting for nearly 70% of building energy use. Global grid investment increased from about USD 300 billion annually to USD 400 billion in 2024, while battery-storage investment exceeded USD 50 billion. Smart city growth also faces integration and security challenges. Among 33 OECD countries, 88% had interoperability frameworks, but only 67% had API standards, 61% had metadata standards, and 52% had open-source frameworks.

ENISA reviewed more than 11,000 incidents, with public administration representing 19% of targets and transport 11%. AI use in internal government operations increased from 70% to 86%, while public-service adoption reached 75%. Building electricity use rose by more than 600 TWh, or 5%, in 2024. ITU Study Group 20 introduced 57 work items, while more than 250 cities now use nearly 100 U4SSC indicators supported by 19 UN agencies.
