Andreessen Horowitz Raises $15B to Cement U.S. Tech Leadership
Venture capital firm Andreessen Horowitz (a16z) raised $15 billion across multiple funds in 2025, representing roughly 18% of all U.S. venture capital deployed last year.
The new capital spans several dedicated strategies: American Dynamism ($1.18 billion), Apps ($1.7 billion), Bio + Health ($700 million), Infrastructure ($1.7 billion), Growth ($6.75 billion), and other venture-focused initiatives ($3 billion). Each is designed to bolster the firm’s long-term vision for what Co-Founder and General Partner Ben Horowitz calls “winning the key architectures of the future”—especially artificial intelligence and crypto.
“As the American leader in venture capital, part of the fate of U.S. technology rests on our shoulders,” Horowitz said. “Our mission is ensuring that America wins the next 100 years of technology—by advancing innovation in AI, biology, defense, education, and beyond.”
Andreessen Horowitz remains one of the most active backers of emerging AI startups, supporting firms such as Cursor, OpenAI, and Mistral AI, alongside investments in leading consumer and enterprise names including Figma, Okta, Roblox, and Airbnb.
Horowitz also emphasized the importance of regulatory alignment: “If we fail to push the country’s policies in the right direction, America will lose its lead in technology—and once that slips, everything else follows.”
