a16z Unveils $1.1 Billion Machine Age Fund to Build Physical AI Infrastructure

Venture firm Andreessen Horowitz has raised a $1.1 billion 'Machine Age' fund specifically dedicated to accelerating the physical buildout required for next-generation artificial intelligence.

Andreessen Horowitz (a16z) has announced the creation of its new $1.1 billion 'Machine Age' fund. Designed to support startups building the physical underpinnings of the AI revolution, the capital will focus on energy generation, specialized compute data centers, high-density robotics, and industrial automation.

The fund highlights a major shift in venture capital from pure software models to capital-intensive hardware and infrastructure investments required to sustain scaling laws.

Partner Marc Andreessen noted that scaling frontier intelligence now depends as much on physical grid transformer capacity and robotic dexterity as it does on algorithmic breakthroughs.
