Anthropic wanted to buy MatX, an AI chip startup founded by former Google engineers, for roughly $7 billion. Then it changed its mind. Now the two companies are reportedly exploring a design partnership instead, a shift that says a lot about how the biggest AI labs are thinking about hardware strategy in 2026.
The abandoned bid is notable for its sheer size. A $7 billion offer would have represented a significant premium over MatX’s current valuation, which landed in the multi-billion dollar range after a $500 million Series B round in February 2026. That round was led by Jane Street and Situational Awareness LP, and it turned a startup barely three years old into one of the most closely watched chipmakers in the AI space.
Why Anthropic wanted MatX, and why it walked
The logic behind the acquisition was straightforward. Anthropic, which has built its business around the Claude family of models, needs specialized hardware to run those models efficiently at scale. Buying MatX would have given Anthropic instant access to a team of chip designers with deep Google TPU pedigree and a product, the MatX One, specifically engineered for large language model workloads.
MatX was founded in 2023 by engineers who cut their teeth building Google’s Tensor Processing Units, the custom chips that power much of Google’s AI infrastructure. The MatX One chip is designed to deliver higher throughput and lower latency for LLM inference and training. Shipments are expected to begin in 2027.
