Silicon Valley venture capital giant a16z has closed its first hardware infrastructure fund, “Machine Age,” at $1.1 billion, targeting AI processors, memory chips, networking equipment, and robotics. The fund is co-led by former VMware CEO Raghu Raghuram and general partner Martin Casado. a16z cites intensifying AI infrastructure supply bottlenecks and surging hardware startup activity as core motivations. Over the past year, semiconductor and autonomous machine startups raised roughly $100 billion, with Cerebras going public and Groq striking a $20 billion licensing deal with Nvidia—signs of sustained sector momentum. Casado argues AI demand is still growing, making supply-side investment logical.
Key Elements
Venture capital heavyweight Andreessen Horowitz (a16z) announced that its first fund dedicated to hardware infrastructure—”Machine Age”—has closed at $1.1 billion. The fund will focus on AI processors, memory chips, networking equipment, data storage, and robotics, marking a major pivot for a firm renowned for software investing toward physical hardware.
The new fund is co-led by a16z managing partner Raghu Raghuram and general partner Martin Casado. Describing the fund’s investment scope, Raghuram said: “Simply put, think of it as everything inside the four walls of a data center—this fund will invest in all of it.”
Raghuram is a Silicon Valley veteran whose career began at Netscape, where he worked alongside a16z co-founder Marc Andreessen. He later served as VMware’s CEO for years before joining a16z last year. Casado also oversees the firm’s software infrastructure fund, and other partners will participate in the new fund’s operations.
A Strategic Shift from Software to Hardware
a16z’s classic portfolio includes Facebook, Instagram, Anduril, OpenAI, Coinbase, as well as recently listed SpaceX and AI coding tool Cursor, which it acquired for $60 billion. For years, Andreessen and Casado treated software as the core of their investment thesis, but as AI infrastructure supply bottlenecks have become increasingly acute, that strategy is undergoing a fundamental shift.
Explaining the pivot, Casado noted: “Every time we enter a new technology era, it puts pressure on infrastructure, but we’ve never seen such dramatic change. From chips and memory all the way to power, every link in the hardware supply chain is capacity-constrained.”
He also revealed that the direct impetus for launching a standalone fund was noticing a growing wave of exceptional entrepreneurs flooding into hardware. “Our North Star tends to be entrepreneurs and what entrepreneurs are interested in. Over the past few years, startup activity in hardware has been extraordinarily vibrant.”
A Hundred-Billion-Dollar Sector Heating Up
According to PitchBook, semiconductor and autonomous machine startups raised approximately $100 billion from investors over the past year. Meanwhile, some venture capital has already achieved exits in infrastructure startups, further fueling private-market enthusiasm for the space.
Chip company Cerebras completed its IPO in May, while another chip startup, Groq, licensed its technology to Nvidia in a $20 billion deal late last year. These cases provide evidence for the return potential of hardware infrastructure investments.
Raghuram believes the new fund also represents the venture capital industry “returning to its roots.” He said: “If you look back at Silicon Valley’s history, the earliest venture capitalists were largely people from early semiconductor companies who spent years evaluating and investing in semiconductor projects.”
Responding to AI Bubble Concerns
Notably, while the new fund stands at $1.1 billion, regulatory filings show it represents only a small fraction of a16z’s total assets under management, which exceed $100 billion.
Facing market concerns about an AI bubble and potential correction, Casado disagrees. He argues that while valuations in some segments may pull back, overall demand continues to grow. “In my view, the number one metric for the health of this space is demand, and from what I’m seeing, demand is persisting. As long as demand keeps growing, investing on the supply side is certainly rational.”
As AI compute demand continues to climb—from upstream chip design and manufacturing to downstream data center operations—hardware infrastructure is becoming a new battleground for venture capital. a16z’s launch of a dedicated fund is both a strategic alignment with industry trends and a reflection of top-tier VC firms’ conviction in the long-term value of AI physical infrastructure.
