a16z Raises $1.1B Machine Age Fund
Andreessen Horowitz (a16z) launched the $1.1 billion Machine Age Fund to finance the physical infrastructure underpinning AI — from semiconductors, memory, interconnects and storage to data centers, robotics, cooling, power, materials, real estate and home AI appliances. The fund prioritizes energy-efficient, high-performance systems and supply-chain scale-up, representing a deliberate shift from a software focus to investing in physical systems that a16z calls a social and national imperative. The firm said hardware startups now account for over 20% of its deal flow and will leverage prior hardware bets (Skydio, SpaceX, Anduril, Waymo) and partners with deep data-center and hardware experience to accelerate the buildout.
