New York, Feb 25, 2026, 16:35 EST — After-hours
Palantir Technologies Inc. (PLTR.O) shares were down 3.4% in after-hours trading on Wednesday, last at $134.19. The stock swung between $127.44 and $134.39 in the regular session and traded 52.5 million shares.
The move comes as investors digest a burst of insider transactions and a new defense-linked partnership involving the data analytics firm. Both can matter to traders trying to gauge near-term share supply and the pace of contract flow.
Software names were broadly weaker on the day. The iShares Expanded Tech-Software Sector ETF fell about 4.7%, steeper than the roughly 1% slide in the SPDR S&P 500 ETF and the 1.2% drop in the Invesco QQQ Trust tracking the Nasdaq 100.
In a Form 4 filed Tuesday, Chief Executive Alex Karp reported selling 493,025 Class A shares on Feb. 20 at weighted-average prices mostly between about $132 and $136 after RSUs for 975,000 Class B shares vested. The filing said the sales were automatic to cover tax withholding; RSUs are stock awards that vest over time, and Rule 10b5-1 plans are preset trading plans. (SEC)
Other executives disclosed similar tax-related sales around the same Feb. 20 vesting date. Chief Financial Officer David Glazer sold 17,438 shares, Chief Technology Officer Shyam Sankar sold 168,004, and President and Secretary Stephen Andrew Cohen sold 327,088, filings showed. (SEC)
Chief Revenue Officer and Chief Legal Officer Ryan Taylor sold 19,988 shares, while Chief Accounting Officer Jeffrey Buckley sold 3,936 shares in a series of transactions on Feb. 20 and Feb. 24, the filings showed. (SEC)
Separately, GE Aerospace said on Tuesday it had been awarded a Defense Logistics Agency contract to boost readiness for the Air Force’s J85 engine and would work with Palantir on the digital logistics platform. “By integrating data across the enterprise and applying AI to predict demand,” said Asha Belarski, a GE Aerospace executive.

But valuation remains the sticking point for some investors. Reuters reported earlier this month that Palantir forecast first-quarter revenue of $1.53 billion to $1.54 billion and 2026 revenue of $7.18 billion to $7.20 billion; Karp said the platform uses “granular permissioning capabilities.” “Valuation question marks won’t disappear,” said eToro analyst Zavier Wong. “Palantir remains priced for perfection, which means it will need to continue executing in future quarters.” (Reuters)
Into Thursday, traders will watch for any further insider filings and follow-up contract announcements as the sector steadies. Palantir said in its annual report that its proxy statement for the 2026 annual meeting will be filed within 120 days of its Dec. 31 year-end — a deadline of April 30. (SEC)
