# Palantir Insiders Sell $138M in PLTR Stock — CEO Karp's Career Sales Hit $3.28 Billion

> Six Palantir insiders sold $137.7M in PLTR stock on Feb 20, led by CEO Alex Karp ($66M), co-founder Stephen Cohen ($43.7M), and CTO Shyam Sankar ($22.5M). Karp's career selling now totals $3.28 billion.

Six Palantir Technologies insiders sold a combined $137.7 million in PLTR stock on February 20, 2026, in what ranks among the largest single-day insider selling events of 2026. CEO Alexander Karp led with $65.96 million, bringing his career insider selling total to a staggering $3.28 billion. The $138M Sell Day Insider Role Transactions Value Career Total Shares After Alexander Karp CEO 10 $65.96M $3,279M 6,432,258 Stephen Cohen Co-Founder 5 $43.74M $939M 592 Shyam Sankar CTO 5 $22.47M $865M 642,786 Ryan Taylor Chief Revenue Officer 5 $2.67M $191M 219,421 David Glazer CFO 5 $2.33M $168M 392,370 Jeffrey Buckley Executive 6 $0.52M $7M 43,108 Total: 6 insiders, 36 transactions $137.7M $5,449M Cohen Nears Complete Exit The most striking detail: co-founder Stephen Andrew Cohen sold down to just 592 shares — effectively a complete exit. After $938.7 million in career sales, the co-founder of Palantir now holds a position worth less than $80,000. For context, Cohen co-founded Palantir with Peter Thiel and Alex Karp in 2003. This near-total liquidation stands in contrast to CEO Karp, who still retains 6.43 million shares worth approximately $870 million at current prices. Karp's $3.28 Billion Pattern CEO Karp's selling is prolific even by tech CEO standards. His $3.28 billion in career insider sales places him among the most aggressive insider sellers of any publicly traded company. For comparison: 10 transactions on Feb 20 alone — selling at prices between $133.73 and $135.67 $65.96M in a single day — a routine occurrence for Karp 6.43M shares retained — still a substantial position worth ~$870M CTO Sankar: $865M in Career Sales Shyam Sankar sold $22.47 million, adding to his $865 million career total. Like Karp, Sankar maintains a meaningful retained position of 642,786 shares (~$87M). Collective Career Sales: $5.4 Billion Together, these six insiders have sold over $5.4 billion in PLTR stock over their careers. The Feb 20 sell represents just 2.5% of their lifetime liquidation — an ordinary day in what has become one of the most sustained insider selling programs in tech history. For PLTR investors, the selling is entirely within established patterns. But the scale remains remarkable: $138 million in a single day from insiders who have collectively monetized $5.4 billion in company stock.
