OpenAI is committing $10 billion to AMD chips to diversify away from Nvidia dependence.
AMD's stock surged approximately 43% following reports that OpenAI is acquiring a 10% stake in the chipmaker, with the deal including a commitment for 6 gigawatts of AMD Instinct GPUs—one of the largest single AI hardware supply agreements ever. The announcement comes just over two weeks after Nvidia announced a $100 billion investment in OpenAI. Under the agreement, OpenAI will deploy 6 gigawatts of AMD Instinct GPUs over multiple product generations, beginning with the MI450 series in the second half of 2026, extending through AMD's future GPU platforms and deepening a partnership that started with the MI300X and MI350X lines. To align company incentives, AMD has issued warrants for up to 160 million shares—roughly 10% of its total equity—that vest as deployment milestones are achieved and are tied to both AMD's stock price performance and OpenAI's ability to scale its infrastructure.
AMD's CFO Jean Hu stated that the partnership could deliver "tens of millions of dollars in revenue for AMD" and be "highly accretive to earnings." For AMD's CEO Lisa Su, the deal represents validation of the company's comeback story, with her saying that the partnership "brings the best of AMD and OpenAI together to create a true win-win, enabling the world's most ambitious AI buildout." For OpenAI's Sam Altman, the partnership serves as a strategic hedge—a way to diversify supply beyond Nvidia while securing long-term compute capacity. The financial markets responded immediately, with AMD's market capitalization jumping nearly $70 billion over the weekend as its stock surged around 37% between the market close on Friday and the open on Monday. At the time of writing, AMD was trading approximately 43% higher than before the partnership details were announced, with options data showing nearly $6 million in bullish AMD call positions purchased just days before the news broke.
Nvidia currently controls around 94% of the GPU market and an estimated 80% of the AI GPU market, largely due to its mature CUDA software ecosystem and unparalleled scale in data center deployments. However, AMD's new Instinct MI300X accelerators are beginning to close the gap, delivering competitive performance-per-watt and lower cost per TFLOP, particularly for inference-heavy workloads. Major hyperscalers such as Microsoft, Oracle, and Amazon Web Services have begun exploring AMD as a viable second-source option for AI computing. While analysts suggest the deal may shift market sentiment more than immediate performance, Wired noted that OpenAI's endorsement has "instantly elevated AMD's relevance in the AI chip race."
The OpenAI-AMD partnership signals a potential structural shift in the balance of power across the AI hardware industry, with OpenAI now holding equity ties with both Nvidia and AMD as a strategic hedge against relying on a single supplier. For the first time in years, Nvidia faces a credible rival backed by both capital and customer demand, representing not merely a financial transaction but a turning point in the ongoing race for AI dominance.
