Andreessen Horowitz Raises $15B Across Funds, Capturing 18% of U.S. Venture Capital in 2025

Andreessen Horowitz has raised more than $15 billion in new capital reinforcing its position as one of the most influential venture firms shaping the future of technology in the United States.

The new funds span multiple strategies, including American Dynamism ($1.176 billion), Apps ($1.7 billion), Bio + Health ($700 million), Infrastructure ($1.7 billion), Growth ($6.75 billion) and other venture vehicles totaling roughly $3 billion.

Altogether he firm accounted for more than 18% of all venture capital allocated in the U.S. in 2025.

“Giving People a Shot” as a Venture Mandate

In a blog post titled “Why Are We Here? Why Did We Raise $15B?” co-founder Ben Horowitz framed the raise not simply as a capital event but as a reaffirmation of the firm’s founding philosophy.

Venture capital, Horowitz argued, exists to give people a shot — an opportunity to build, contribute and create value regardless of background, identity, or circumstance.

He contrasted this model with systems that promise equality of outcome but ultimately suppress opportunity arguing instead that the freedom to pursue success even imperfectly, has delivered compounding benefits for society over time.

America’s Role in Global Technological Leadership

Horowitz tied this philosophy directly to the American system, which he described as the most consistent engine in history for expanding opportunity and improving the human condition.

Over the past 250 years, he wrote, the rise of the United States has coincided with unprecedented access to economic and technological opportunity.

At a moment of rapid technological change, Horowitz warned that American leadership is not guaranteed. If the U.S. fails to lead in foundational technologies, it risks losing ground economically, militarily, geopolitically and culturally — with consequences extending far beyond its borders.

AI and Crypto as Strategic Battlegrounds

Andreessen Horowitz views artificial intelligence and crypto as the core architectures that will define the next era of innovation. The firm plans to deploy capital across these technologies while applying them to sectors critical to human flourishing, including healthcare, biology, defense, public safety, education and entertainment.

Crypto received particular attention as an area where U.S. leadership is under threat. Horowitz pointed to early signs that unclear regulation and policy missteps could push innovation offshore weakening America’s competitive position.

Capital, Policy, and the Next 100 Years

Beyond investing, a16z sees policy engagement as essential to sustaining technological leadership. Horowitz argued that without supportive regulatory frameworks, even the strongest innovation ecosystems can erode.

With this latest fundraise, Andreessen Horowitz signaled its intention to invest in what it calls “generational companies” — while working to ensure the economic and strategic benefits accrue to the United States, its allies, and the broader global economy over the next century.
