This infographic breaks down the estimated $106 trillion in infrastructure investment expected between now and 2040, both by sector and by region, based on data from McKinsey & Company.

Infrastructure Investment by Region Through 2040

At a macro level, infrastructure spending will be driven by growing populations, urban expansion, and the global shift toward low-carbon and digital systems.

Africa is projected to attract $5 trillion, and Oceania roughly $2 trillion—reflecting smaller economies but growing urban infrastructure demand.

Infrastructure Investment Forecast by Sector

On a sectoral level, global infrastructure spending is forecasted to be concentrated in a few key areas, as the table below shows:

The transportation sector leads with $36 trillion expected to be invested in roads, ports, airports, railways, and other projects. Overall, transportation accounts for around one-third of global infrastructure investment through 2040.

According to McKinsey, the energy sector will require massive capital flows for renewable energy projects, grid modernization, and growing energy needs, racking up $23 trillion in estimated investment by 2040.

Digital infrastructure is the third-biggest sector attracting investment, with an estimated $19 trillion flowing into fiber networks, telecoms, data centers, satellites, and associated services by 2040.

Social infrastructure (health, education, and public facilities) will see another $16 trillion, while waste and water systems and agriculture together add $11 trillion more. The aerospace and defense sector rounds out the list at $2 trillion.
