Research and Markets reported that the global Infrastructure Sector Market size was estimated at $2.89 trillion in 2025, and is now expected to reach $3.92 trillion by 2030, given that it grows at a CAGR of 6.27% during the forecast period between 2025 and 2030. The COVID-19 pandemic severely impacted national economies and the financial health of governments, businesses, and individuals. Infrastructure saw lower usage rates, which led to shortfalls in financing and maintenance, as financial resources were diverted to urgent healthcare and supply chain needs. The pandemic caused both a demand and supply shock, but the global infrastructure construction output still expanded in 2020.
In a McKinsey and Company report titled “The Infrastructure Moment,” published on September 9, the necessity for a mindset shift in how governments, investors, and industry operators approach infrastructure was highlighted. McKinsey projected that an investment of $106 trillion is needed through 2040 to meet the global demand for infrastructure. Of the seven infrastructure verticals mentioned in the report, Transportation & logistics take the largest share at $36 trillion, followed by energy & power at $23 trillion. The remaining investment goes to digital infrastructure, social infrastructure, waste & water infrastructure, agriculture, and defense. Regionally, the investment needs are uneven, with Asia alone accounting for more than two-thirds, or $70 trillion. The Americas are projected to require ~$16 trillion, and Europe ~$13 trillion.
