Advanced Micro Devices (AMD) on Wednesday announced a strategic partnership with Anthropic and said it will invest up to $5 billion in the artificial intelligence company. The deal marks one of the largest direct investments by a chipmaker into an AI startup and signals AMD's accelerating ambition to challenge Nvidia's stranglehold on the AI computing market.
Under the agreement, Anthropic will deploy 2 gigawatts of AMD's next-generation Instinct MI450 Series graphics processing units in AMD Helios rack-scale solutions. The first gigawatt — a measure of power that has become the standard metric for describing AI data center capacity — is scheduled for deployment in the first half of 2027.
"We are thrilled to deepen our partnership with Anthropic and deploy AMD Helios at gigawatt scale," AMD CEO Lisa Su said in a statement.
Anthropic has experienced explosive growth this year, driven largely by the success of its AI coding assistant, Claude Code. The company reported in May that its run-rate revenue had surged past $47 billion, up from approximately $10 billion for the entirety of 2025. It closed a funding round at a $965 billion valuation the same month and has confidentially filed for an IPO with the SEC in June.
The AMD deal is the latest in a string of massive infrastructure agreements Anthropic has signed as demand for its Claude models strains its computing capacity. In May, the company forged a deal with Elon Musk's SpaceX to use all the compute capacity at the Colossus 1 data center in Memphis, Tennessee, paying $1.25 billion per month through May 2029. It also inked multi-billion-dollar agreements with Amazon and multi-gigawatt compute deals with Google and Broadcom in April.
The partnership with AMD mirrors a similar arrangement the chipmaker struck with Anthropic's rival OpenAI, where AMD issued OpenAI a warrant for up to 160 million shares of AMD common stock — equivalent to roughly 10% of the company — with vesting milestones tied to deployment volume and AMD's share price.
For AMD, the Anthropic deal represents a critical strategic win in its battle to erode Nvidia's estimated 80-90% market share in AI GPUs. The MI450 series and Helios rack-scale platform are AMD's most ambitious push yet into the high-end AI data center market, and having a customer of Anthropic's stature commit at gigawatt scale provides both validation and long-term revenue visibility.
The deal comes as the broader AI industry faces mounting scrutiny over infrastructure spending. Alphabet posted its first negative free cash flow since 2004 this week as AI capex doubled to $45 billion, and Tesla also missed earnings estimates. AMD's investment signals confidence that the AI buildout — and the demand for GPUs that powers it — has years of runway ahead.
