Airbnb, Inc. (ABNB) – Form 144 filing

Insider Aristotle Balogh has filed notice to dispose of 600 Class A shares through Fidelity on or after 7 Aug 2025. At the stated aggregate market value of $72,300, the planned sale equals roughly 0.00014 % of Airbnb’s 429.1 m shares outstanding, implying no dilution impact to public shareholders. The shares stem from a 19 May 2025 restricted-stock vesting.

The filing also discloses Balogh’s recent activity: between 29 May and 31 Jul 2025 he sold 6,875 shares for gross proceeds of about $922,808 across nine transactions, indicating a steady liquidation pattern. Form 144 is a notice of intent, not confirmation of execution; however, continued insider selling can influence investor sentiment even when volumes are immaterial to float.
