Palantir CTO Files to Sell $50.8 Million in Stock After AI Selloff

Palantir's chief technology officer, Shyam Sankar, has filed to sell 300,000 shares with a listed market value of $50,760,000. The SEC accepted his Form 144 notice at 4:26 p.m. ET on November 10, 2026. The filing names Morgan Stanley Smith Barney as broker and gives November 10 as the approximate sale date.

The notice arrived after a bruising stretch for the stock. Palantir fell 9.73% on November 5, the same day the S&P 500 dropped 4.36% in the AI and chip selloff. That drop ended eight consecutive down sessions that began on October 27.

The shares have since steadied. They rose 5.50% on November 9, slipped 0.22% on November 10, and gained 2.12% to close at $172.40 on November 11. That close remains 17.53% below the October 9 closing high of $209.05, and the stock traded at $169.80 after hours.

What does the Form 144 actually commit to?

Very little, as filings go. A Form 144 states an intent to sell; a later Form 4 will confirm whether any shares changed hands and at what prices.

The shares originate from restricted stock units that vested between May 20, 2025 and August 20, 2025. The notice reports no Palantir sales by Sankar in the prior three months.

The form also says he relies on a Rule 10b5-1 plan, a selling schedule set in advance. He adopted it on August 10, 2026, roughly three months before the selloff. The listed value is simply the share count priced at the $169.20 close on November 9.

How large is the sale for Palantir?

Small. The block equals roughly 0.013% of the 2,306,705,341 shares outstanding listed on the form. At the November 11 close, it was worth about $51.7 million — a rounding error in the company's capitalization, though a tidy sum in almost any other context.

Sankar's Form 4 filings show a pattern of scheduled selling. He sold approximately:

• $27.5 million on November 20, 2025
• $22.5 million on February 20, 2026
• $22.5 million on May 20
• $24.1 million on July 2
• $5.4 million on August 6

That totals roughly $102 million over the period. On August 6 he converted 35,000 Class B shares and sold them at weighted average prices between about $153.40 and $157.44. He afterward reported 642,786 Class A shares held directly, 599,899 in a trust he co-manages, and 3,628,598 Class B shares — though that form notes it does not list all of his holdings.

Why did the stock fall despite strong results?

The selloff came days after an emphatic quarter. On November 2, Palantir reported revenue of $2.313 billion, up 96%. U.S. commercial revenue rose 148% to $984 million, and U.S. government revenue rose 96% to $953 million.

Management raised full-year revenue guidance to between $8.530 billion and $8.534 billion, and guided fourth-quarter revenue to $2.649 billion to $2.653 billion. The business got better while the stock got worse, which says the dispute was about price, not performance.

The multiple explains most of it. Palantir trades at about 245 times earnings and 189 times free cash flow. Executives at companies valued this high routinely sell on a schedule. Vested stock counts as income in the year it vests, and much of their wealth sits in a single stock, so a planned sale tells observers very little about their confidence.

What should investors watch next?

Sankar's filing likely covers taxes owed on vested stock under a plan set in August, while the quarter describes a faster-growing business. The principal risk sits in the share price, not the filing.

Shares are down 3.01% in 2026 from a $177.75 year-end close. The 52-week range runs from $106.37 to an intraday high of $212.94. The November 11 close sits about 11.2% above the $154.99 close on November 5; a close below that level would signal the AI selloff has resumed and would undercut the benign reading of this filing.

The next checkpoint is Sankar's Form 4. The SEC posted no filings on Veterans Day, so it will likely arrive on November 12 or November 13. A sale well above 300,000 shares, or any transaction outside the August plan, would change the assessment entirely.
