Michael Burry closed his December 2026 put options on Nvidia and Palantir without rolling them into later expirations, while retaining 2027 Palantir and Invesco QQQ Trust puts. He said he reduced risk across his entire portfolio during September and is comfortable holding cash while monitoring what he called an "interesting" fall market. Position sizes were cut proportionally, but Lululemon, Molina Healthcare and MercadoLibre remained his top three long holdings; Oracle, Palantir and Nebius Group remained his leading short positions, followed by Nvidia and the iShares Semiconductor ETF. Palantir and Nvidia shares fell 0.2% and 0.5%, respectively, in morning trading. An earlier tracker update also said Burry trimmed Lululemon, Molina Healthcare, MercadoLibre and Temple & Webster. Burry has criticized Palantir's financial practices, while Palantir and Nebius Group have announced a partnership naming Nebius Palantir's preferred sovereign AI infrastructure partner.
