Nvidia to invest up to £75 billion in OpenAI in landmark AI partnership

Chipmaker Nvidia said it plans to invest up to £75 billion in OpenAI in a landmark strategic partnership that will see OpenAI build new data centers powered by Nvidia's AI processors, while Nvidia takes an equity stake in the company. OpenAI will purchase millions of Nvidia processors to support its growing AI workloads and, in turn, bolster Nvidia’s processor business as demand for AI infrastructure expands.

The deal comes as competition among technology giants to secure access to the energy and chips required for AI growth intensifies. Nvidia chief executive Jensen Huang described the arrangement as a major step forward for the industry, saying, “This is a giant project.” The partnership positions Nvidia and OpenAI at the center of a broader shift in how AI hardware and software are funded and deployed.

Under the terms, Nvidia will invest in OpenAI in stages and receive equity in return. OpenAI, for its part, will purchase millions of Nvidia processors, a move that could generate billions of dollars in revenue for Nvidia over the life of the partnership. Bryn Talkington, a partner at Requisite Capital Management, told CNBC that the structure could be highly favorable for Jensen Huang, describing it as a virtuous loop: “Nvidia invests in OpenAI, which OpenAI then turns back and gives to Nvidia.”

The market response reflected the deal’s significance: Nvidia’s shares rose about 3.7 percent, lifting the company’s market valuation to around £3.2 trillion on the trading day.

The collaboration also reflects the international attention AI partnerships are drawing. OpenAI chief executive Sam Altman was noted to have joined U.S. President Donald Trump on his state visit to the United Kingdom last week, underscoring the high-level interest from policymakers and business leaders in AI’s trajectory.

Industry observers say the arrangement could reshape how AI workloads are financed and supplied, accelerating the deployment of new data centers and hardware that can run advanced AI models. By tying a major processor maker directly to one of the most prominent AI developers, the deal blends hardware provisioning with software development at a scale that could influence hundreds of AI projects worldwide. In an industry where access to energy, compute power, and specialized accelerators is a bottleneck, the partnership is seen as a strategic bet on keeping pace with rapid AI demand and the next generation of AI services.
