Nvidia is reportedly in talks to back OpenAI’s biggest data center bet yet with a $250 billion guarantee. It’s what it says about how Nvidia wants to grow — not just selling chips, but financing demand for them. And more financing means more data centers, which means more Nvidia chips. Nvidia and OpenAI are reportedly working out a different deal to cover that cost, according to CNBC. That makes a $250 billion guarantee nearly as big as the company’s entire balance sheet.
