Airbnb co-founder Nathan Blecharczyk sold $22 million of stock into the record close

Nathan Blecharczyk, who co-founded Airbnb▲+0.24% — Airbnb, up 0.24 percent today and remains its chief strategy officer, a director and a 10 percent owner, sold 114,514 Class A shares for $21,900,783 on November 6 and 9, 2026, his Form 4↗, the SEC filing insiders must make within two business days of trading, shows ¹². Each session, his trust converted super-voting Class B shares into tradable stock, sold, and stopped at an exact floor: 20,567 shares left, both times ¹. Prices ran from $190.61 to $196.07, and he gifted another 4,077 shares ¹.

The beat that set an all-time high

The selling began the day after Airbnb's November 5 report↗: revenue of $4.87 billion, up 19 percent, earnings of $3.16 a share against $2.85 expected, and a fresh authorization to buy back up to $12 billion of stock ³⁴. Shares jumped 11 percent in late trading and closed November 6 at what veteran trader Howard Lindzon flagged on Stocktwits↗ as a weekly all-time high ³⁵. No quarter in the 12 on file at the SEC grew faster ⁶.

The sale was scheduled 14 months ago

Nothing here was improvised. A Rule 10b5-1 plan, which schedules insider trades in advance precisely so they do not signal fresh information, was adopted on August 28, 2025 ¹. EDGAR, the SEC's public filing database, lists 25 Form 4 filings↗ from Blecharczyk this year, eight in August alone, including a August 17 sale of 13,615 shares for $2.5 million ⁷⁸. The record shows a founder drip-selling into strength on autopilot.

Who bought at the top

The money question is who takes the other side of $22 million in founder stock at an all-time high, and the filing does not say ³. A $12 billion buyback is a standing bid for whoever needs to sell, which makes Airbnb itself the most natural buyer ³.

Money moved the other way that week, too: Airbnb disclosed it sold intellectual property to chief executive Brian Chesky's private AI lab for $7.1 million in cash, a company-to-founder flow The Inference traced on November 10↗ ³.

He kept $8 billion of the stock

The filing is not an exit. Blecharczyk still holds about 44.2 million Class B shares, roughly $8 billion at the November 11 close, on top of the trust floor and 74,808 direct shares; the week's sales come to about a quarter of one percent of that position ¹². Bulls can also point to the multiple: Airbnb trades above 30 times earnings against rival online-travel platform Expedia's 12, with growth accelerating ⁹.

The next Form 4 meets the buyback

The stock has since slipped to $181.13, below every price in his filing ². The next Form 4 will show whether the August 2025 plan keeps feeding shares into a market the company is paying to support, and the year-end accounts will show what the buyback actually paid ². The plan fixes his floor at 20,567 shares ¹; the cost of absorbing that supply shows up only later, in what the buyback reports paying.
