Infrastructure supports the movement of energy, water, goods, people, and data, making it the physical backbone of the global economy. As populations grow and systems age, the need for investment continues to rise.

In the U.S. alone, more than $3.5 trillion is needed by 2033 to modernize surface transportation, according to the American Society of Civil Engineers. Additional investment is required across energy, aviation, and water systems. Globally, infrastructure needs exceed $80 trillion through 2040, according to Swiss Re.

Because governments often lack the resources to fund these projects alone, private companies are playing a growing role, creating long-term opportunities for investors.
