Andreessen Horowitz, also known as a16z, raised more than $15 billion across five new funds, marking the firm’s largest fundraising to date. The capital includes $6.75 billion for scaling startups, $1.7 billion for an AI infrastructure fund, and $1.12 billion for investments in areas such as defense, housing, and supply chain. The fundraising represents over 18% of all U.S. venture capital allocated in 2025, according to a16z.
The venture capital firm, a key backer of Facebook, Instagram, Coinbase, and Lyft, emphasized that its new funds will focus on U.S. technological leadership amid growing global competition, particularly from China. Co-founder Ben Horowitz described the moment as a critical opportunity for the country to maintain its technological edge.
The fundraising follows a16z’s prior $7.2 billion multi-fund raise in April 2024 and brings its total assets under management to more than $90 billion. The five new funds include both early-stage and growth-focused vehicles, with the AI infrastructure fund specifically designed to support chipmakers, cloud AI services, and enterprise AI applications. The largest fund, $6.75 billion for scaling startups, will target companies across SaaS, enterprise, fintech, and biotech, while the national interest fund aims to back technologies aligned with U.S. strategic priorities. These allocations demonstrate a16z’s continued strategy of pairing AI-driven innovation with broader economic and national competitiveness goals.
