PLTR insider ownership: who sold, why, and what they still hold

What stands out

Two officers sold more than 25% of vested holdings: Ryan Taylor (35% of holdings, $16.6M, all under a disclosed plan) and Jeffrey Buckley (30% of holdings, $2.3M, all under a disclosed plan).Ryan Taylor: largest sale, Jan 2, 2026 · Jeffrey Buckley: largest sale, Aug 20, 2026
Three officers sold shares but ended with larger stakes, because more shares came in than were sold: Alex Karp (sold 1.79M, 3.1% of starting holdings; 3.90M added), Stephen Cohen (sold 995K, 7.7% of starting holdings; 2.02M added) and David Glazer (sold 61K, 14% of starting holdings; 102K added).Alex Karp: largest sale, Aug 20, 2026 · Stephen Cohen: largest sale, May 20, 2026 · David Glazer: largest sale, Dec 12, 2025

Percentages cover 11 of 12 officers and directors. Left out: Shyam Sankar (holdings couldn't be fully reconciled). Disclosed company stock is not an insider's whole wealth.

11 of 12 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (9 exactly, 2 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 11 of 12 officers and directors. Left out: Shyam Sankar (holdings couldn't be fully reconciled). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$869M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $869M across 5,893,957 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $659M · 76%

24%

The lighter segment is sales with no plan disclosed in the filing ($210M), including tax-related sales outside a plan.

Taxes

$478M of sales (55.1%) cite tax obligations in their footnotes, $268M of them also under a plan. Example: Jeffrey Buckley, Aug 20, 2026

Charitable gifts · 354K shares

Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertainty1 insider whose holdings couldn't be fully reconciled

Shyam Sankar: holdings couldn't be fully reconciled (difference of 599,899 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +749,899 shares on Jul 2, 2026 (Reporting Person and the Sankar Irrevocable Remainder Trust u/a/d 4/20/2020). Filing, Jul 2, 2026

Footnote: "This transaction is part of a related series of transactions undertaken on July 2, 2026 pursuant to a preexisting Rule 10b5-1 trading plan, intended to satisfy the affirmative defense conditions of Rule 10b5-1(c), entered into on March 11, 2026 by the Reporting Person and the Sankar Irrevocable Remainder Trust u/a/d 4/20/2020 (the "Remainder Trust"). The Reporting Person converted 35,000 shares of Class B Common Stock to Class A Common Stock and immediately sold the resulting shares of Class A Common Stock in the open market, and the Remainder Trust sold 150,000 shares of Class A Common Stock "

Alexander Moore: minor difference of -1 share. Difference is under 0.5% of holdings.

Lauren Stat: minor difference of -1 share. Difference is under 0.5% of holdings.

Inferred rename: "SMR Capital Holdings LP" is treated as the same holder as "75 and Sunny LP", because the old name was never reported again and the new one opened with the same balance (215,053 shares). Old name, new name

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology498 filings from SEC EDGAR, and how we read them

All 498 Forms 3, 4 and 5 filed for Palantir Technologies Inc. (SEC CIK 1321655) from Sep 22, 2020 to Oct 5, 2026, retrieved from SEC EDGAR on Oct 7, 2026. Prices are the ones reported in each filing, often weighted averages. 44 filings were left out because Palantir Technologies Inc. filed them as an owner of another company's stock.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
