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

> The sales were scheduled in August 2025, but they landed the day after Airbnb's Q3 beat and a $12 billion buyback authorization, with the co-founder's trust selling down to an exact 20,567-share floor at all-time-high prices. The most natural buyer of founder stock up there is now the company's own program.

[Nathan Blecharczyk](https://theinference.org/markets/people/nathan-blecharczyk), who co-founded [Airbnb](https://theinference.org/markets/companies/airbnb) 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](https://www.sec.gov/Archives/edgar/data/1559720/000119312526455964/0001193125-26-455964-index.htm), the SEC filing insiders must make within two business days of trading, shows [1][2]. 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](https://globalbusinessnewstoday.com/articles/airbnb-q3-2026-earnings/): 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 [3][4]. Shares jumped 11 percent in late trading and closed November 6 at what veteran trader Howard Lindzon flagged on [Stocktwits](https://stocktwits.com/howardlindzon/message/668462597) as a weekly all-time high [3][5]. No quarter in the 12 on file at the SEC grew faster [6].

*Chart: **Revenue reached a record $4.87B in Q3 2026, the quarter the founder sold into** Column chart of Airbnb quarterly revenue from Q4 2023 to Q3 2026, rising to $4.87 billion in Q3 2026, the highest quarter on file*

*Quarterly revenue, US$ billions, from Airbnb's SEC filings. Q3 2026 was reported on November 5, 2026; the founder's sales settled November 6 and 9. [1][3][4][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](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001834147&type=4&dateb=&owner=include&count=40) from Blecharczyk this year, eight in August alone, including a August 17 sale of 13,615 shares for $2.5 million [7][8]. 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](https://theinference.org/markets/people/brian-chesky)'s private AI lab for $7.1 million in cash, a company-to-founder flow [The Inference traced on November 10](https://theinference.org/article/airbnb-paid-7-1-million-to-ceo-brian-chesky-s-private-ai-lab-and-approved-a-12-billion-buyback) [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 [1][2]. 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].

*Chart: **Growth bottomed at 6.1% in Q1 2025 and has climbed back to 18.9%, a 12-quarter high** Line chart of Airbnb year-over-year revenue growth for 12 quarters to Q3 2026, falling to 6.1 percent in Q1 2025 and climbing back to 18.9 percent in Q3 2026*

*Year-over-year change in quarterly revenue, percent, computed from Airbnb's reported figures in its SEC filings. Growth bottomed at 6.1% in Q1 2025 and has risen in three of the last four quarters. [6]*

## 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.

## Takeaway

A scheduled sale, a record high and a $12 billion bid: the founder's drip is now the buyback's problem.
