It goes on from there …Nvidia’s $250 billion backstop to OpenAI will let the money-burning AI lab lease space at the largest data center ever built. OpenAI doesn’t have an investment-grade rating, so Nvidia is essentially lending its own. Nvidia’s backstop for OpenAI is literally that — OpenAI is trying to sign a lease and its landlord, SoftBank, doesn’t like the tenant risk. The AI boom is not broad-based in the same way at all. And while it’s possible to interpret that fact in other ways, it certainly seems to me like it spells trouble.
