Airbnb CEO Brian Chesky used a reported Manhattan property purchase as a punch line, writing on X, "There’s at least one legal airbnb property in NYC," while linking to a Wall Street Journal post reporting that Airbnb bought an $81.5 million Park Avenue South property. So far, the public sourcing is that X post and the Journal link it points to, which is enough to explain the joke and the reaction, but not to independently verify the broader story beyond that report.
