> I don’t know why anyone would want to invest in OpenAI on the open market

I can only assume hype. That’s why Sam Altman has the job he has. You don’t see the CEO of Anthropic going on the Tonight Show. He’s there to bring OpenAI to the forefront of people’s minds, and uninformed investors will follow.

All catches up to you eventually though.

Hasn't seemed to catch up with Tesla, which is still highly valued despite making a pretty mediocre car compared to the competition. Even if one makes the argument that Tesla vehicles are of good quality, it's still a high valuation that seems to show no sign of dropping.
