Andreessen Horowitz Raises $1.1B Machine Age Fund Targeting AI Infrastructure

Andreessen Horowitz has closed a $1.1 billion fund specifically dedicated to AI infrastructure investments, branded the Machine Age Fund. The fund signals sustained conviction from one of the most influential VC firms that infrastructure — compute, networking, storage, and the platforms connecting them — remains the critical bottleneck and investment opportunity in the AI stack. For startups building in the infrastructure layer, this represents a well-resourced backer actively seeking deployment targets in that space. Developers and engineering teams should expect continued rapid expansion of AI-native infrastructure tooling and services as this capital flows into the ecosystem. It also reinforces the multi-year capital cycle underpinning the current AI build-out, suggesting infrastructure constraints won't ease through organic market correction alone.
