The Motley Fool reported that insiders at Nvidia, Palantir, and Alphabet were net sellers over the five years beginning in October 2021, with combined net selling of about $17.5 billion. That is the publication’s compiled estimate, not an SEC-reported aggregate. Selling is worth noticing, but the total alone does not show that executives expect a downturn: individual transactions can reflect tax withholding or pre-arranged trading plans as well as discretionary sales.
How much insider selling did The Motley Fool report?
In its October 6, 2026 article, The Motley Fool calculated the following net sales and purchases for the five-year period beginning in October 2021. These are the publication’s figures; they have not been independently reconstructed from company-by-company SEC filings.
| Company | Reported net insider selling | Reported insider purchases |
|---|---|---|
| Nvidia | $6,862,723,289 | $250,000 |
| Palantir | $6,514,528,061 | $7,837,856 |
| Alphabet | $4,150,615,765 | $95,045,005 |
| Combined | About $17.5 billion | Not stated as a combined figure |
The figures put a large dollar value on reported insider transactions, but they combine activity over five years and do not identify a single shared reason for selling. Nor are they an official SEC statistic.
Why an insider sale does not automatically signal a bearish view
A Form 4 records transactions by officers, directors, and certain other insiders. Its transaction codes, footnotes, and related company disclosures matter: a disposition can be an open-market sale, a sale arranged under a pre-existing plan, or shares withheld to meet tax obligations when equity compensation vests. An aggregate dollar total does not by itself distinguish among those circumstances or establish that insiders are making a forecast about the stock.

Tax withholding and plan-based sales in a Palantir Form 4
A Form 4 filed August 24, 2026, by Palantir Chief Accounting Officer Devon Klein covers transactions dated August 20 and 21. It identifies an automatic sale to cover required tax withholding connected with vesting restricted stock units, and also reports open-market sales under a Rule 10b5-1 plan entered into March 12, 2026. The filing says the sales complied with that plan. These entries illustrate why readers should examine transaction details rather than treat every reported disposition as an unscheduled decision to reduce exposure.
Plans can be disclosed before sales take place
Palantir’s 2025 annual report says CEO Alexander Karp adopted a Rule 10b5-1 arrangement on November 21, 2025. It allowed for potential sales of up to 360,000 shares, subject to price and/or other conditions, and was scheduled to run through November 25, 2026, unless completed or expired earlier. The disclosed possibility of sales is not the same as proof that every potential sale occurred.

How to check what a reported sale means
- Find the insider filing. Look for the Form 4 associated with the transaction and note the filing date and transaction date; they may differ.
- Read the transaction details and footnotes. Check whether the filing describes an open-market sale, a tax-related disposition, or a transaction under a trading plan. Do not infer the purpose from the share count alone.
- Check company disclosures for plan context. A company report may describe when a Rule 10b5-1 plan was adopted, its conditions, and its term. That information helps distinguish a plan disclosed in advance from a one-off transaction.
- Separate the fact from the inference. A filing establishes that a reported transaction took place; it does not establish that the insider expects the share price to fall or that the transaction predicts future returns.
Alphabet’s annual report provides an example of where to look: it says actual sales under disclosed Rule 10b5-1 arrangements will be reported in Section 16 filings with the SEC. Those filings and their footnotes are more informative about a particular transaction than a cross-company aggregate.

The scale of the reported sales can prompt reasonable questions about insider activity, but the available figures do not show that insiders collectively forecast a crash. The cited transactions document sales and purchases; they do not establish a causal link between those totals and subsequent share performance. Arguments about valuation or a possible AI bubble are separate investment judgments, not conclusions proved by the transaction totals.
Recommended Free Tools
Palantir’s insider-trading policy says insiders may not trade Palantir securities while aware of material nonpublic information, subject to the policy’s stated exceptions. That restriction is not evidence that a permitted plan-based or tax-related sale reflects a bearish view; legality and motive are separate questions.
The five-year compilation ends with the period reported by The Motley Fool on October 6, 2026. Later transactions or changing valuations would require updated filings and figures; the totals should not be read as current indefinitely.
