A “The Big Short” trader sees Anthropic's slowdown as a stress test for the AI boom

By TheStreet · October 30, 2026.

TheStreet's headline says a trader known from "The Big Short," the film about the 2008 mortgage crisis, argues that Anthropic's slowdown is putting the AI boom to the test. We only have the headline and the article's URL. We do not have the content, the figures behind this alleged slowdown, or the trader's name. For that reason, we will not take them as fact or fill in the gaps.

Our take is deliberately cautious. A voice famous for betting against bubbles pointing at a specific company is a market opinion, not an operational data point. For the argument to hold, we need to see exactly what has slowed: revenue, growth rate, demand or computing capacity. And it must be compared with prior expectations, because growth below what was priced in is not the same as a decline.

More broadly, the AI cycle mixes two planes that should not be confused. One is financial valuation, which can correct sharply and trigger a painful short-term adjustment. The other is real-world adoption of the technology, which moves at a different pace and is measured in usage, productivity and use cases that work. A stock market correction does not reverse the latter, although it can reshuffle who funds and who leads.

Our thesis is that headlines like this are useful as a gauge of expectations, not as a verdict on the technology. If the article provides verifiable numbers on the slowdown, it will merit deeper analysis. Until then, neither euphoria nor alarm: the long-term question of whether AI will ultimately generate real value and abundance will not be answered by one quarter's share price.
