Anthropic's $7 Billion Takeover of MatX Falls Through
Anthropic (anthropic on 164news.com) had planned to acquire chip startup MatX for a staggering $7 billion, but subsequently walked away from the deal. This news was reported by Reuters on August 28, 2026, citing sources familiar with the negotiations.
The discussions initially focused on an acquisition but shifted towards a partnership. However, the reasons behind Anthropic’s decision to abandon the purchase remain unclear. Reuters’ report relies on anonymous sources and has not been officially confirmed by either company.
MatX: A Specialized AI Chip Startup
MatX, founded in 2023 by Reiner Pope and Mike Gunter, is a small but specialized company. Pope led AI software development for Google’s tensor processing units (TPUs), while Gunter was a lead designer on the TPU hardware. They developed processors tailored for large language model training rather than general-purpose computing.
The startup raised a substantial $500 million Series B in February, with investors including Jane Street, Leopold Aschenbrenner’s Situational Awareness fund, Marvell, Spark Capital, and the Collison brothers. MatX aims to offer processors that significantly outperform Nvidia’s GPUs for specific tasks, with volume shipments scheduled for 2027.
Valuation Disparity
Interestingly, Reuters reported that MatX is currently raising funds at around $4 billion, which is nearly three-quarters of the $7 billion acquisition price discussed earlier. This disparity highlights the value a buyer places on control and time in such deals.
Anthropic has been actively developing silicon capabilities and had previously confirmed an in-house chip team. They are also in talks with Samsung for custom part manufacturing. The financing landscape has expanded dramatically, with Broadcom seeking over $60 billion in debt to fund its chips destined for Anthropic, and AMD committing $5 billion alongside a two-gigawatt deployment.
Market Trends and Strategic Choices
The market has responded similarly, with startups like Etched—which follows a similar model—raising $500 million at a $5 billion valuation, and several accelerator startups collectively raising about $1.6 billion this year.
Given these trends, a partnership agreement is not necessarily a retreat for Anthropic. Acquiring MatX would have presented challenges with design integration while simultaneously launching chips into data centers. A supply agreement provides the necessary silicon without organizational complexities. It also allows MatX to continue selling its products to other customers, which is crucial for its Series B investors who likely did not back it as a single-customer supplier.
