According to the latest market research study published by P&S Intelligence, the U.S. public–private partnership market was valued at USD 34.8 billion in 2024 and is poised to reach USD 61.4 billion by 2032, progressing at a solid CAGR of 7.5% between 2025 and 2032. This growth trajectory is powered by the urgent need for infrastructure modernization, greater innovation, and the integration of private-sector expertise into public projects.

What was once limited to transportation and energy now spans sectors like healthcare, education, and digital technology. A notable surge in PPP initiatives in 2025 reflects the government’s intensified focus on attracting private investments to bridge public funding gaps. For instance, 924 PPPs were launched in the higher education sector alone over the past two decades, targeting online and international programs and fast-track bootcamps.

The private sector’s participation has become crucial to address outdated systems and drive operational excellence. As governments commit to modernizing infrastructure while navigating fiscal constraints, the PPP model continues to offer mutually beneficial, scalable solutions across sectors.

Key Insights

• The transportation sector dominates the market with a 65% share, driven by the need to revamp highways, bridges, railroads, and airports. In October 2024, USD 2.4 billion was approved for 122 railway infrastructure upgrades in 41 states and Washington, D.C.
• The fastest-growing segment is technology & telecommunications, fueled by rising demand for broadband networks, smart city projects, and digital infrastructure development.
