The famed short seller Michael Burry is moving up the timeline for his bearish thesis on the artificial intelligence boom, stating in his Monday investment newsletter that he believes the AI bubble "may burst sooner than later." He is switching his major tech short positions to put options with June expiration dates to gain more cost-effective leverage. This includes converting Micron, Nebius, and SOXX iShares Semiconductor ETF shorts to puts, and enlarging his Palantir put position, with some expiries extending to September 2027.
