Andreessen Horowitz Secures Over $15 Billion in New Capital

Andreessen Horowitz has revealed it has raised more than $15 billion in fresh funding, a sum that accounts for more than 18% of all U.S. venture capital allocated in 2025, according to co-founder Ben Horowitz. This latest round pushes the firm’s assets under management past $90 billion, placing it on par with Sequoia Capital as one of the world’s largest venture capital firms. Notably, a16z has cultivated close relationships with sovereign wealth funds, including at least one from Saudi Arabia.

With a workforce numbering in the hundreds and offices in California, New York, and Washington D.C., Andreessen Horowitz has expanded its reach globally, now employing staff across six continents. In December, the firm launched its first Asian office in Seoul, focusing on its crypto initiatives.

Breakdown of New Funds

The newly raised capital is distributed among five funds: $6.75 billion for growth-stage investments, $1.7 billion each for applications and infrastructure, $1.176 billion dedicated to “American Dynamism,” $700 million for biotech and healthcare, and an additional $3 billion for other venture strategies. The scale of these funds prompts questions about both the sources and destinations of such significant capital.

Funding Sources and Notable Investors

Andreessen Horowitz has traditionally kept details about its limited partners and performance metrics private. When asked about its investor base and capital returns, the firm declined to comment. However, it is public knowledge that CalPERS invested $400 million in 2023, marking the first time the firm accepted funds from a major California pension plan—likely due to differing views on transparency. Additionally, Sanabil Investments, part of Saudi Arabia’s Public Investment Fund, includes Andreessen Horowitz in its portfolio.

International Ties and Political Influence

The firm’s connections to Saudi Arabia are well established. In 2023, Marc Andreessen and Ben Horowitz appeared alongside WeWork’s Adam Neumann at a conference sponsored by a major Saudi sovereign fund, discussing their $350 million investment in Neumann’s real estate startup, Flow. At the event, Horowitz described Saudi Arabia as a “startup country,” noting that its leader is referred to as “his royal highness” rather than a founder.

Marc Andreessen has also become a frequent presence at Mar-a-Lago since Donald Trump’s 2024 election win, where he has reportedly contributed to discussions on technology, business, and economic policy. Early last year, he took on an “unpaid intern” role in Elon Musk’s Department of Government Efficiency, helping vet candidates for the incoming administration—including for defense and intelligence roles. Meanwhile, Scott Kupor, a16z’s first hire, was appointed Director of the U.S. Office of Personnel Management in the summer.

Strategic Focus: “American Dynamism” and AI

A16z’s current investment strategy centers on “American Dynamism,” targeting sectors such as defense, aerospace, public safety, housing, education, and manufacturing. This portfolio closely mirrors the priorities of the U.S. Department of Defense, with investments in companies like Anduril (autonomous defense systems), Shield AI (military drones), Saronic Technologies (autonomous naval vessels), and Castelion (hypersonic missiles). The firm is betting on a resurgence of American manufacturing, especially as it notes that the U.S. could deplete its missile stockpile in just over a week in a potential conflict with China over Taiwan, with a three-year timeline to replenish supplies.

Another major focus is artificial intelligence, where a16z has made significant investments across the AI ecosystem. The firm has backed infrastructure providers like Databricks, foundational model developers such as Mistral AI, OpenAI, and xAI, and application companies including Character.AI and others.

Track Record and Industry Impact

Andreessen Horowitz has a history of high-profile successes. Its $25 million investment in Coinbase grew to an $86 billion valuation at the company’s 2021 IPO. Other notable wins include Airbnb (which went public at over $100 billion), Slack (acquired for $27.7 billion), and GitHub (sold to Microsoft for $7.5 billion). According to Tracxn, the firm’s portfolio features 115 unicorns, 35 IPOs, and 241 acquisitions. The firm has also been active in cryptocurrency investments, though details on those returns are less transparent.

In a recent blog post, Ben Horowitz stated, “As the American leader in Venture Capital, the fate of new technology in the United States rests partly on our shoulders.” He described the firm’s mission as “ensuring that America wins the next 100 years of technology.”

Whether a16z will achieve this ambitious goal remains to be seen. What is clear is that the firm has become exceptionally skilled at raising massive sums—$15 billion in this latest round—to support its vision of American technological leadership, with influence stretching from Riyadh to Mar-a-Lago to the Pentagon. The strategy is bold, and so far, it’s proving effective.
