Anthropic Commits $20B to AMD Chips as AMD Pledges $5B Back Into Anthropic Stock
AMD and Anthropic swap billions in chips and stock
Anthropic has committed to buy more than $20 billion worth of AI compute capacity from AMD, while AMD has pledged up to $5 billion to buy Anthropic stock, according to the Wall Street Journal and the two companies' own filings.
The arrangement came together after the WSJ reported that hyperscalers — large cloud providers — are limiting how much computing power Anthropic can access. The Wall Street Journal report is the basis for that detail.
AMD has described the arrangement as a "strategic partnership" meant to lock in a major client.
Key numbers behind the deal
- Anthropic's commitment to AMD: over $20 billion in AI compute services.
- AMD's commitment to Anthropic: up to $5 billion in stock purchases.
- AMD's latest quarterly report lists "investment commitments of up to $5.0 billion, subject to certain contingencies, which are expected to be made through fiscal year 2028."
- The deal covers up to two gigawatts of AMD's Instinct MI450 chips, starting in the first half of 2027.
- Anthropic ran an operating loss above $8 billion in 2025 on $4.6 billion of revenue, according to the source material.
What AMD and Anthropic have said
AMD announced its original $5 billion "strategic partnership" in July, months before its September IPO prospectus laid out Anthropic's commitment to acquire more than $20 billion in AMD AI compute capacity, according to the source material.
AMD's CEO said, "We are thrilled to deepen our partnership with Anthropic."
Anthropic co-founder Tom Brown said in July, "Access to compute is central to keeping Claude at the frontier and meeting demand from our customers."
The filing detail drawing scrutiny
AMD's latest quarterly report discloses investment commitments of up to $5.0 billion through fiscal year 2028, but does not name Anthropic, even though the amount matches AMD's commitment to invest in the company, according to the source material.
Questions raised about the structure
Contractors normally provide services for payment rather than putting that money back into a client's equity. The source material notes that a skeptical reading of the two deals is that they amount to a de facto rebate through share buybacks. That interpretation is opinion, not a confirmed fact.
AMD's investment is described in the source material as helping keep Anthropic's valuation optimistic despite its losses. That is an assessment, not a confirmed outcome.
