As February 24 showed, February 20, 2026, was one of the most momentous days on record in terms of insider activity for Palantir (NASDAQ: PLTR) stock.

Specifically, six high-ranking company insiders, led by CEO Alex Karp, dumped more than $137 million worth of PLTR equity within a single day.

Among them, Karp executed the single biggest sale, offloading 493,025 shares at an average price of $133.78 for a staggering total of $65.9 million. 

Interestingly, despite its massive scale, the CEO’s Palantir stock sale was only the third-largest in the last 12 months. 

Alex Karp also dumped $66 million worth of PLTR in November 2025, while Director Stephen Cohen raised a massive $310 million by offloading the equity in March of the year.

On the same day, the technology giant’s chief technology officer (CTO) and executive vice president, Shyam Sankar, raised about $22.5 million.

Lastly, though the final three trades were large in their own right, they are minuscule in comparison as they range between $520,601 and $2.67 million. These three February 20 Palantir stock insider sales were made by David Glaze, Ryan Talor, and Jeffrey Buckley.
