Andreessen Horowitz closes $1.1B fund for the physical side of AI
The Machine Age Fund targets chips, robotics, data centers and connected hardware — a bet that AI's next bottleneck is atoms, not algorithms.
Andreessen Horowitz closed its Machine Age Fund at $1.1 billion this month, dedicated specifically to companies building the physical infrastructure AI increasingly depends on: chips, memory, networking hardware, storage systems, data centers, robotics and connected home devices.
It's a deliberate departure from the software-first venture playbook that defined the early LLM boom. Investors are telling a consistent story this quarter — that the 'vague AI pitch' era of easy funding is over, and capital is rotating toward defensible, capital-intensive problems where AI meets the physical economy.
The fund's thesis also implicitly acknowledges a supply constraint the whole industry has been circling for two years: model capability is arguably outpacing the power, silicon and physical deployment capacity needed to actually run it at scale. Betting on the shovels, not just the gold, is no longer a contrarian position — it's becoming the consensus one.
