Glazer sells 17.1K PLTR shares for $2.3M across 5 transactions; holds 375.2K post-sale

David A. Glazer executed 5 separate sales totaling 17,128 shares for $2,330,129.59 on 2026-05-20, reducing his holding by 4.4% to 375,242 shares. The blended average sale price of $136.04 sits near current price of $136.88, suggesting execution close to market levels. His prior five PLTR sales (all on 2026-02-20) all generated positive 90-day returns (+1.2% to +4.1%), indicating none were well-timed; this pattern of subsequent stock appreciation after his sales suggests he has historically sold ahead of rallies at this ticker. Cross-ticker, his broader track record shows a 75% well-timed rate on 20 prior sells with an average 90-day return of -11.4%, but that outperformance has not replicated at PLTR, where his timing has lagged.

Ryan D. Taylor sells 19.7K PLTR shares for $2.7M at avg $136.04; holds 199.8K post-transaction

Ryan D. Taylor executed 5 separate sales totaling 19,662 shares for $2,674,859.35 on 2026-05-20, reducing his PLTR position by -9.0% versus pre-transaction holdings of 219,421 shares. His cross-ticker track record shows an avg 90d return of -11.7% after prior sells with a 90d well-timed rate of 75.00%, but at PLTR specifically, 0 of 5 prior sells were well-timed at the 90-day mark—all 5 prior same-ticker sales showed positive 90-day returns (+1.2% to +4.1%), meaning the stock rose after those sales. The current price of $136.88 is -34.0% from the 52-week high of $207.52 and down -10.3% over the 30-day window, yet PLTR's fundamentals remain strong with annual revenue growth of +56.2% and net income of $870,527,000.00 on quarterly revenue of $1,632,583,000.00.

CEO Alexander C. Karp sells 397,744 shares ($54.1M) at PLTR on 2026-05-20; holds 6.43M shares post-transaction.

Alexander C. Karp executed 5 separate sales totaling 397,744 shares for $54,109,936.01 at a blended average price of $136.04. This represents a -5.8% reduction from his pre-transaction holdings of 6,830,002 shares. At the current price of $136.88, the stock is -34.0% from its 52-week high of $207.52 and down -10.3% over the past 30 days. Karp's cross-ticker track record shows 20 prior sells with an average 90-day return of -7.7% and a 90-day well-timed rate of 50.00%. His prior 5 trades specifically at PLTR, all sells executed on 2026-02-20, posted positive 90-day returns ranging from +1.2% to +3.4%, with 0 of 5 being well-timed by the sell-timing metric (a negative 90-day return would indicate well-timed selling). The company reports revenue of $1,632,583,000.00 with net income of $870,527,000.00, annual revenue growth of +56.2%, and a P/E ratio of 144.08.

Shyam Sankar sells 165,514 shares at PLTR for $22,516,875.64 across 5 transactions on 2026-05-20.

Shyam Sankar executed 5 separate sales totaling 165,514 shares for $22,516,875.64 at prices ranging from $132.95 to $136.61, reducing his holdings by -20.5% from 808,300 to 642,786 shares. His cross-ticker track record shows 20 prior sells with a 90-day well-timed rate of 75.00%, indicating he has historically sold before declines across his full trading history. However, at PLTR specifically, his prior 5 sales all showed positive 90-day returns (ranging from +1.2% to +4.1%), meaning the stock rose after those sales, and none were well-timed at the 90-day mark. The current stock price of $136.88 is -34.0% from the 52-week high of $207.52, and the 30-day price change is -10.3%, placing this sale in a period of recent weakness. PLTR's fundamentals show strong growth (annual revenue growth of +56.2%) and substantial profitability ($870,527,000.00 net income on $1,632,583,000.00 quarterly revenue), though the P/E of 144.08 reflects a premium valuation.

Stephen Andrew Cohen sold 319,934 shares of PLTR for $43,524,501.18 across 5 transactions on 2026-05-20, reducing holdings by 99.8%.

Stephen Andrew Cohen executed five separate sales totaling 319,934 shares for $43,524,501.18 on 2026-05-20, at prices ranging from $132.95 to $136.61 with a blended average of $136.04. The transaction reduced his holdings from 320,526 shares to 592 shares, representing a near-complete exit from his PLTR position. This massive, coordinated liquidation stands out sharply against his prior trading pattern at PLTR: his five most recent sales at this ticker (all on 2026-02-20) were substantially smaller and have historically underperformed on a 90-day basis, with none showing the negative 90-day returns that would indicate well-timed selling. His cross-ticker track record shows a 75.00% well-timed rate on sells, yet his PLTR-specific history shows 0 of 5 prior sells were well-timed at the 90-day mark, suggesting his timing discipline has not historically transferred to this security. The stock is trading at -34.0% from its 52-week high and -10.3% down over the past 30 days, providing context for the scale of this exit but not yet determining whether the transaction will prove prescient or premature.
