AMD to invest up to $5 billion in Anthropic; AI startup to buy up to 2 GW of chips

Advanced Micro Devices will sell Anthropic tens of billions of dollars' worth of AI servers and invest as much as $5 billion in the Claude maker, in a deal that would strengthen its foothold in a market dominated by rival Nvidia.

The announcement on Wednesday ‌marks the latest ⁠so-called circular ⁠deal in the AI industry, where chipmakers invest in AI firms that are among their biggest customers. Nvidia has been in talks to invest $30 billion in ChatGPT creator OpenAI.

Buying AMD chips would secure Anthropic much-needed AI computing capacity. The startup has emerged as one of the leaders in Silicon Valley's artificial intelligence race, thanks to strong adoption of its enterprise tools such as Claude Code. "It's strategically significant, as each win deepens AMD's credibility as the number-two to Nvidia and supports the slow, steady share gains underpinning its AI growth story," said Emarketer analyst ⁠Jacob Bourne.


Anthropic ‌will buy up to two gigawatts of AMD's latest-generation Instinct MI450 chips, starting in the first half of 2027, the companies said. AMD's investment in Anthropic will be tied to achieving certain ⁠deployment milestones.

AMD executives have said 1 gigawatt of computing power, enough for roughly 750,000 U.S. homes, can cost double-digit billions of dollars.

Shares of the Santa Clara, California-based company rose 2.4%. The stock has more than doubled in value so far this year.

In October, AMD announced a multi-year deal with OpenAI that would also bring in tens of billions of dollars in annual revenue while giving the ChatGPT creator the option to buy up to roughly 10% of the chipmaker.

Anthropic needs computing capacity

"Access to compute is central to keeping Claude at the frontier and meeting demand from our customers," ‌Tom Brown, co-founder and compute head at Anthropic, said on Wednesday.

The startup has moved aggressively in recent months to overcome capacity constraints for its services. It agreed in May to rent the full computing power of SpaceX's Colossus 1 facility ⁠in Memphis, which houses more than 220,000 Nvidia processors and gave it 300 megawatts of new capacity.

Meta Platforms is also in talks to lease computing power to Anthropic in a potential deal worth up to $10 billion over two years, a source familiar with the matter said last week.

Under the latest deal, Anthropic would use some of the AMD chips at its own data centers and lease additional capacity through cloud providers and new AI cloud companies, according to the Wall Street Journal, which first reported the news.

AMD was in talks to provide a financial backstop for Anthropic's future data-center leases, the report said.
