Microsoft is already one of the largest OpenAI investors, but now Nvidia is investing up to $100 billion in OpenAI too. Though that may well be a form of circuitous, parasitic relationship where Nvidia invests money in OpenAI, so it can, in turn, purchase Nvidia hardware for its various data center projects. Crucially, however, this deal also marks OpenAI as one of the first customers for Nvidia's next-generation hardware. This deal will see Nvidia invest an initial $10 billion once the deal is agreed upon, with the first Nvidia hardware set to be delivered in late 2026. No matter how you look at it, it hints at a bubble, which OpenAI CEO Sam Altman accepts is very real.
