a16z creates a $1.1B Machine Age fund focusing on hardware to “open the throttle and accelerate the physical buildout of AI”
Andreessen Horowitz has launched a new “Machine Age” fund with $1.1 billion raised. The firm's aim with the new fund is to “open the throttle and accelerate the physical buildout of AI.”

Context & Ripple Effects
a16z had already allocated capital to AI infrastructure in its 2024 fund set and, in January 2026, expanded a $1.25B infrastructure fund to $3B after backing companies early in their development. The Machine Age vehicle narrows that broader infrastructure thesis toward the physical systems needed to support AI demand.
The move also extends the firm’s earlier multi-strategy fund allocation to AI infrastructure into a dedicated hardware mandate. Coverage across financial and technology outlets frames the fund around AI supply constraints, making the financing vehicle itself a signal that infrastructure bottlenecks have become an investable category.
First-order effects
AI hardware builders gain access to a dedicated $1.1B pool from a16z, rather than competing solely within its broader AI-infrastructure allocation.
a16z adds a specialized vehicle alongside its enlarged infrastructure fund, giving it another route to make early hardware investments as AI usage and token consumption expand.
Second-order effects
Other venture firms pursuing AI infrastructure deals face stronger competition for early-stage hardware companies, particularly where a16z can pair the new mandate with its existing infrastructure portfolio.
Hardware founders can pitch financing around physical AI capacity rather than only model development, widening the set of projects treated as core AI investments.
Third-order effects
If dedicated funds continue to form around physical AI capacity, AI investing will increasingly be organized by infrastructure layers—from capital and compute to the hardware that supplies them—rather than as a single software category.
The shift raises the importance of financing capacity constraints as a determinant of which AI companies can scale, concentrating influence among investors able to fund both early companies and infrastructure-heavy buildouts.
The trend: AI venture capital is moving from broad software exposure toward specialized financing for the physical infrastructure that supports growing model usage.
Amazing to see A16Z, founded on “software is eating the world”, to lead in investing in the physical world! They co lead our round at @unconvAI . I'm AI, the model is the hardware. Always has been. LFG!
Chips, memory, interconnects, storage, robotics. Compute hardware infrastructure is undergoing the largest transformation in 30 years. Whatever innovation challenges lie ahead, computer science will be central to the solution. And we've raised $1.1B to help that along.
New $1.1b fund for physical AI. We are witnessing a reinvention of compute infrastructure at historically unprecedented magnitude and breadth. It's time to build the Machine Age. @a16z
AI is a world-defining category alongside the microprocessor, the steam engine, and electricity. Every one of them required an entirely new physical world to be built. We raised $1.1B to build this one.
$1.1B into the “Machine Age” is another signal of where capital thinks this is going, the next phase of AI isn't only about better models. It's more compute, more autonomous software, more agents acting on behalf of people and companies, and eventually more machines transacting

The world's AI infrastructure is going to be reinvented. The data centers, the racks, the cooling, the power. It's the largest infrastructure opportunity in the history of computing. We raised $1.1B for it.
Spoke to @RaghuRaghuram about Andreessen Horowitz's new $1.1 billion fundraise. When I asked him why it wasn't a carve out from the existing mega-$15B raise from earlier this year, he said it's due to different capital cycles for startups building in the physical AI world More
As @bhorowitz said: “You need a whole new infrastructure and never has it been more high impact as it is on this one. So not only do we need new chips, new system software, we need new ways of doing power, we need to replace copper. It's absolutely everything.” 💪💪💪 (also how
