Anthropic explores chip design partnership with MatX after walking away from $7B acquisition

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.
