**The market-implied 71.5% probability on “No” for a Banksy Instagram post by September 30 stems primarily from the artist’s long-standing pattern of highly infrequent activity on the platform.** The @banksy account maintains just 154 total posts despite millions of followers, with new uploads typically reserved for confirming major new murals, installations, or direct responses to controversies rather than routine updates. A September 18 post calling out Guess for unauthorized use of the “Flower Thrower” image fits this established cadence, offering no signal of accelerated posting in the final ten days of the month. Traders weigh the absence of announced projects, guild-style precursor signals, or confirmed statements against the short remaining window, while acknowledging that an unexpected London installation or legal development could still trigger a last-minute confirmation post.
