Palantir (PLTR) CEO Alexander Karp Sells Shares After RSU Vesting
What Happened
Alexander C. Karp, Palantir’s Chief Executive Officer, had 975,000 restricted stock units (RSUs) incrementally vest on May 20, 2026. Following vesting he converted Class B shares into Class A and sold 397,744 Class A shares in multiple open‑market trades that same day to cover required tax withholding. The reported sales generated approximately $54.11 million in proceeds (sales executed at prices ranging roughly $132.48–$136.835; weighted averages reported per trade line).
Key Details
- Transaction date: May 20, 2026 (Form 4 filed May 22, 2026 — timely filing).
- Sales executed: 397,744 shares sold across multiple open‑market trades; reported weighted sale prices per tranche between $132.95 and $136.61; total proceeds ≈ $54.11M.
- RSU vesting: 975,000 RSUs vested (each RSU = 1 share of Class B common stock); 397,744 of those were converted to Class A and sold.
- Purpose of sales: Automatic sales to cover tax withholding obligations; trades conducted under a Rule 10b5‑1 trading plan.
- Shares retained after sales: approximately 577,256 vested shares remained (975,000 vested − 397,744 sold), though the Form 4 states it does not disclose all holdings — see issuer proxy for full ownership details.

Context
This was not a discretionary open‑market sell indicating a trade for liquidity/taxes: it was a routine tax‑withholding sale tied to RSU vesting and executed under a prearranged 10b5‑1 plan. For derivative/RSU activity: the filing shows conversion/exercise entries reflecting the vesting and conversion of RSUs into Class B/Class A common stock, with the converted Class A shares sold immediately to satisfy withholding.
