Venture capital firm Andreessen Horowitz announced Friday it has raised $1.1 billion for a new fund focused exclusively on AI hardware infrastructure — a bet that the physical buildout of AI's backbone is the next trillion-dollar opportunity.
The 'Machine Age Fund' will invest across the full AI hardware stack: chips, memory, networking, storage, data centers, cooling systems, robotics, and home AI appliances. In a blog post, the firm described the opportunity as "a once-in-a-generation chance to rearchitect these as platforms, all the way down to the electricity."
The fund targets what a16z calls a structural supply crunch. "The hardware industry supply side is used to growing 20% to 30% per year at most; not the triple-digit growth that's needed to catch up with demand," the firm said. "This will change, quickly."
The launch comes as AI infrastructure spending has exploded, with hyperscalers like Microsoft, Google, and Amazon collectively committing hundreds of billions of dollars to data center buildouts. a16z argues that the bottleneck is no longer software or models but the physical infrastructure to run them.
The Machine Age Fund is separate from a16z's existing $3 billion AI infrastructure fund, which focuses on AI software for technical buyers. The new fund specifically targets hardware and physical infrastructure, filling a gap that has grown more acute as AI models become larger and more compute-intensive.
