Alexander C. Karp has filed 74 Form 4 disclosures covering a single company: Palantir Technologies (PLTR). Every trade in the record is a sale or a transaction linked to compensation mechanics. His cumulative sell value stands at $334.9 million. There are no open-market purchases, and the acquired value is zero. The pattern is consistent: sell, do not buy.
The most recent cluster of trades occurred on August 20, 2026, with a matching set on May 20 and February 20 of the same year. That cadence lines up with expiring option grants and the automatic sale of shares to cover taxes, which appear as codes M, S, and C in the filings. The August tranche alone included eight open-market sales, ranging from $88,151 to $53,597,838.95. Total cash from that day was roughly $84.8 million. The May sales were similar in scale, with several transactions between $882,141 and $30,483,391.13.
The pattern leans entirely to the sell side. Every reported disposition is an S code, an open-market sale, not a sale back to the issuer. The M and C entries have no dollar values, which is typical for exercises and conversions that produce no cash gain at filing time. Karp has not bought PLTR shares on the open market in any of the 74 filings. The direction is unambiguous: continuous liquidation of equity positions in Palantir through automated and discretionary sales.
