I’m not necessarily expecting a crash any time soon. (But we average a major correction, what? every 8 years? So if you keep predicting one long enough you will eventually have been right all along.) But I do feel comfortable saying OpenAI and Anthropic are overpriced. For more or less the same reason Cisco was overpriced in the late ‘90s. It’s not that what they were making wasn’t valuable; it’s that we got out over our skis a bit over how much of it the world could actually manage to consume in the immediate future.
Groupon got to pretty much 100% penetration, still crashed and burned right after IPO. I think Zynga followed a similar trajectory.
The bubble can't pop until after an IPO, and that doesn't mean "immediately after".
You can't have a run on a privately held company.
