Venture capital firm Andreessen Horowitz has raised $15 billion to bolster bets across an array of areas including infrastructure, health and what the it calls “American Dynamism,” co-founder Ben Horowitz said in a blog post on Friday.

The bulk of the capital, $6.75 billion, will go toward a growth fund and two $1.7 billion funds focused on apps and infrastructure, respectively.

“At this moment of profound technological opportunity, it is fundamentally important for humanity that America wins,” Horowitz wrote. “There is no other country that comes close to giving everyone a chance to grab that opportunity and build. If America fails to win technologically, it will lose economically, militarily, geopolitically, and culturally. And the entire world will lose as well.”

Andreessen Horowitz is dedicating $3 billion to support other venture strategies and about $1.2 billion to fund American interests such as aerospace and defense, the post said. Some $700 million is going toward biotech and health investments.

The raise is equal to 18% of all venture capital Dollars allocated in the U.S. last year, Horowitz added. It’s more than doubled the amount the firm raised in 2024.

Since its founding in 2009, Andreessen Horowitz has risen to become one of the most prominent venture capital firms, known for early investments in Facebook, Coinbase and Airbnb.

In recent years, the Silicon Valley-based firm has been betting big on defense tech, with investments in Palmer Luckey’s Anduril, Elon Musk’s SpaceX and machine parts maker Hadrian.

The sector has benefitted from President Donald Trump’s ambitious plans to reindustrialize America’s military and manufacturing base. This week, the president also called for a $1.5 trillion defense budget next year.

Both Horowitz and co-founder Marc Andreessen supported President Trump in the 2024 election, though Horowitz later said he would be donating to Kamala Harris’ presidential campaign.
