Palantir (NASDAQ: PLTR) stock insiders have been engaged in extensive selling of PLTR equity since 2026 started with the activity apparently intensifying over the last two weeks.
Specifically, between February 20 and press time on March 3, filings with the Securities and Exchange Commission (SEC) reveal that the company’s senior personnel have dumped more than $400 million worth of Palantir shares.
The largest and most recent trade of the period was made by the billionaire director Peter Thiel. According to a March 2 filing, the businessman offloaded 2 million PLTR shares for an estimated total value of $280 million.
Interestingly, such an estimate indicates that the insider trade was executed in the early morning hours, considering Palantir stock rallied through the day, rising from about $140 to its latest closing price just above $145.
Furthermore, despite its size, the March 2 sale was not the biggest Peter Thiel ever made. In September 2024, within a span of just three days, the billionaire sold more than $1 billion worth of PLTR equity.
Six Palantir stock insiders dump $137 million PLTR shares in a day
Elsewhere, despite each individual trade being significantly smaller in scale, six Palantir insiders dumped approximately $137 million worth of PLTR stock on a single day: February 20.
The biggest transaction of the day involved CEO Alex Karp selling 493,025 shares worth approximately $66 million. Simultaneously, Stephen Cohen offloaded nearly $44 million worth of equity, and Shyam Sankar sold more than $22 million worth of Palantir stock.
David Glazer, Ryan Taylor, and Jeffrey Buckley were responsible for the three smallest sales on February 20, each raising between $520,601 and $2.7 million from their insider trading.
The curious timing of monster Palantir stock insider sales
Lastly, the timing of the three late February insider PLTR stock dumps is interesting as it preceded a rather deep plunge – Palantir shares fell from $135 on the day of the trades to just under $129 on February 24, coincidentally the date the filings were made – but also a substantial subsequent rally.
Overall, despite being down 13.54% year-to-date (YTD) and 8.07% in the red in the last month in the stock market, PLTR shares have risen 9.15% within the most recent week of trading and are, at press time, changing hands at $145.25.
