Barcelona"The real estate market is a ticking time bomb, and I want to bet against it." American director Adam McKay dramatized in the film The Big Short the bursting of the 2007 housing bubble around a key figure: Michael Burry, the investor who bet everything against the U.S. credit market and escaped the crisis with unprecedented gains. More than two decades after those warnings, Burry has chosen a new target: artificial intelligence.

After the bursting of the housing bubble, Burry closed the hedge fund with which he made his bets, Scion Capital, after the controversy caused by his short position against the entire real estate market. Years later, he reopened it, then under the brand Scion Asset Management. In November 2025, his fund's investment report revealed significant short positions in some of the big tech companies favored by the artificial intelligence market.

A few weeks later, however, he closed it to outside investors, alleging that his investment strategy "was not in sync with the market," which was experiencing episodes of unbridled euphoria driven by major tech stocks. Nevertheless, he maintains his public forum presence through the more than popular Substack page, Cassandra Unchained, where he publishes his reflections on the possible AI bubble and explains his personal investments. In a post last week, Burry announced that he was doubling down and "expanding his main shorts," which include Nvidia, Oracle, and Palantir.
