Andreessen Horowitz is betting the next AI winners will be found in silicon, not software.
Andreessen Horowitz launched "Machine Age," a new fund targeting AI supply chain bottlenecks in chips, robots, and hardware, betting that infrastructure constraints will define the next phase of AI growth.
"The whole market started copying it," said Aabhas Sharma, chief technology officer and president at Hebbia, an AI startup that a16z backed with $130 million in 2024, describing the competitive pressure in AI software. The fund announcement, reported by the Wall Street Journal, expands the firm's hardware portfolio beyond existing stakes in SpaceX and Anduril.
The fund targets the physical layer of AI — semiconductor manufacturing, robotics, and industrial hardware — where supply constraints have become the primary bottleneck for AI deployment. The firm's existing AI investments include Hebbia, which raised $130 million in a round led by a16z in 2024, and the fund is expected to deploy capital across early-stage and growth-stage hardware companies.
The move positions a16z to capture value from the AI infrastructure buildout, which has become the dominant theme in venture capital as companies race to secure chip supply and manufacturing capacity. The fund's focus on supply chain bottlenecks suggests the firm sees sustained demand for AI hardware despite concerns about AI spending sustainability.
The fund's launch comes as AI hardware spending has become the defining investment theme in technology. Nvidia's data center GPUs remain the critical constraint for AI model training and inference, with demand outstripping supply since 2023. The chipmaker's dominance has created a supply chain bottleneck that spans wafer manufacturing, advanced packaging, and power infrastructure.
The "Machine Age" fund appears designed to capture value across this supply chain. By investing in chip designers, robotics manufacturers, and industrial hardware companies, a16z is positioning itself to benefit from the physical buildout that AI requires, rather than just the software layer where competition has intensified.
The competitive landscape for AI hardware investment has grown crowded. Sequoia Capital, Lightspeed Venture Partners, and other top-tier firms have all launched dedicated AI infrastructure funds. a16z's existing portfolio includes SpaceX, the rocket company, and Anduril, the defense technology startup — both of which depend on advanced hardware and manufacturing capabilities.
For investors, the fund signals continued conviction in the AI infrastructure buildout. Publicly traded companies in the AI hardware supply chain — including Nvidia, TSMC, and robotics manufacturers — could benefit from increased capital flows into the sector. The fund's focus on supply chain bottlenecks suggests a16z expects the hardware crunch to persist, which would support sustained pricing power for chipmakers and component suppliers.
The fund also reflects a broader shift in venture capital strategy. As AI software startups face increasing competition and compressed margins, hardware companies with proprietary manufacturing advantages and long-term supply contracts are becoming more attractive investment targets. This trend is visible in the recent surge of funding for robotics startups and semiconductor supply chain companies.
Hebbia's experience illustrates the competitive pressure in AI software. The startup, which popularized AI-powered document analysis for Wall Street, has seen its core product replicated by larger rivals including Harvey and Rogo. Sharma said the company's new product version is designed to stay ahead of the market, but the competitive dynamics underscore why a16z is diversifying into hardware.
The fund's success will depend on identifying companies that can solve the most acute supply chain constraints. Advanced packaging capacity, power delivery systems, and robotics automation are among the areas where bottlenecks are most severe. a16z's track record with hardware investments — including its early backing of SpaceX and Anduril — gives the firm credibility in this space.
