More than half of the world’s population already lives in cities. By 2050, that figure will be 70%. These are two UN statistics that are always shared, as they help highlight the importance of urban environments in demographic patterns. Cities have become the main population hubs, which in turn creates new challenges and requires new decisions. In this context, smart cities are emerging both as a potential tool and as a focal point for investment in solutions that address the challenges of both the future and the present.
Smart city investments
Global investment estimates for smart cities show that this is a growing market and one that is already moving multibillion dollar volumes.
A projection by Fortune Business Insights concluded that in 2024 the global smart cities market had already reached a capitalization of 767.75 billion dollars, a figure that would exceed 4.6 trillion by 2032, representing growth of 25.2% in less than a decade. DataM Intelligence’s figures are somewhat different, although they also point to large amounts. Their projections indicate that by 2032 the market will reach 907.12 billion dollars, with investment growth of 25.70% between 2025 and 2032.
Either way, investment opportunities and spending lines tied to smart city projects have continued to grow over recent decades, placing the cities that have embraced the concept in a leading position compared with other urban areas. It could almost be said that smart cities are in a more advanced economic position than other cities. They are able to attract both public and private investment, drawing in resources and reinforcing their role as centers of attraction. But what do smart cities invest their money in?
Investment areas
To begin with, it is important to understand what is meant when discussing a smart city project. It is not just about adding technology or automating certain services, but about a cross-cutting integration that delivers benefits for all urban stakeholders.
Urban management is streamlined, while benefits and improvements with a direct and tangible impact on citizens are also delivered. For example, smart city investments promote sustainable development, understood in the broadest sense of the concept. Waste and traffic management are improved, but opportunities are also created for access to quality jobs and for making urban spaces more resilient. This is where developments such as the cognitive city, come into play, enabling the city itself to be responsive.
This is why the investment areas attracted by smart cities span many different fields and make it possible to capitalize on a wide range of potential resources and tools. As concluded by a study carried out by researchers from Singapore, the Netherlands, the United Kingdom, and China, “the enormous resources poured into their development consist of financial capital, but also natural, human and social resources converted into infrastructure and real estate.”
How smart cities attract capital
However, cities must keep in mind that this is a competitive market, one in which they compete with other smart cities for both private and public investment. After all, public funds are limited, and once an allocation is used up, no further distribution is possible; the same is true for private investment, which is also finite. Cities must showcase their strongest investment opportunities and understand the high interest areas that attract the most attention.
At present, the projects generating the greatest interest, at least according to investment analyses, are those focused on the digitalization of energy and transport. Smart management of urban infrastructure is another area that stands out. In a way, this is not surprising, as these are the areas where cities face the greatest challenges.
Which smart cities receive the most investment
Likewise, the distribution of investment also varies by geography. According to analysis by Fortune Business Insights, North America dominated the market in 2023, with a 40.87% share.
However, other markets are making a strong push through public fund investment, which is accelerating the development of their smart cities and driving digitalization. The European Union is one of the bodies backing this approach, with several public investment programs focused on achieving urban development goals before 2030. In fact, several European cities, such as Warsaw (Poland), Vilnius, (Lithuania), or Bucharest (Romania), rank among those that have risen the most in the Smart City Index.
Several countries in the Middle East are also making significant urban investments, positioning them as an upward trend in smart city spending. DataM Intelligence highlights the public-private investments of Saudi Arabia, the United Arab Emirates, Oman, Qatar, Kuwait, and Bahrain in this area, with an announced cumulative expenditure of 67 billion dollars between mid-2024 and early 2025.
