GMO stated the following regarding Palantir Technologies Inc. (NASDAQ:PLTR) in its fourth quarter 2025 investor letter:

"The other eight U.S. Information Technology stocks that we held short delivered an average performance of more than 63%. Palantir Technologies Inc. (NASDAQ:PLTR), which was the single biggest detractor from absolute returns at the total portfolio level, was up a spectacular 135% for the year and is, somewhat bewilderingly, trading at a price/sales ratio well in excess of 100. Indeed, one of the reasons we remain excited about the Equity Dislocation Strategy is that there are plenty of stocks that continue to surf a wave of speculative excess."
