Eisman Bets the AI Boom Depends on Two Companies


Steve Eisman is warning that the artificial intelligence boom has become increasingly dependent on the fortunes of just two companies: OpenAI and Anthropic.

Eisman Bets the AI Boom Depends on Two Companies

Steve Eisman made his name shorting the housing market before it collapsed. Now he's looking at artificial intelligence and seeing the same problem every bubble has. Too much weight on too few legs.

The AI boom rests on OpenAI and Anthropic. That's it. Two companies. Eisman thinks this is a structural weakness. He's probably right but that won't stop anyone from buying Nvidia at 60 times earnings because a chatbot wrote them a poem about their ex-girlfriend.

OpenAI runs ChatGPT. Anthropic runs Claude. If either one implodes or gets regulated into the ground or decides to pivot into selling artisanal coffee, the entire AI trade could collapse faster than your cousin's cryptocurrency portfolio in 2022. But retail traders don't care about concentration risk. They care about charts that go up and to the right.

Eisman built his career on identifying systemic fragility. Housing prices were propped up by subprime mortgages bundled into securities nobody understood. Now AI valuations are propped up by two private companies nobody can actually invest in. The parallel isn't perfect but it rhymes enough to make him nervous.

Every tech investor on Twitter will call this FUD. They'll say Eisman is old and doesn't understand transformer models or AGI timelines or whatever buzzword makes them feel smarter than they are. Then they'll buy more stocks tangentially related to AI and pray that Sam Altman doesn't wake up one day and decide to become a goat farmer.

The funniest part is that Eisman isn't even shorting anything here. He's just pointing out that pinning a multi-trillion dollar market rally on two companies that could get killed by a regulatory filing or a bad model release is maybe not the most robust investment thesis ever constructed. But what does he know. He only called the last generational collapse. Your Reddit DD probably has better edge.
