Resolution criteria on PolyGram: This market will resolve to "Yes" if Banksy authenticates a new mural or outdoor street artwork between market creation and December 31, 2026, 11:59PM ET. Otherwise, this market will resolve to "No". Only works created between market creation and December 31, 2026 will qualify. Artworks created before this market's timeframe but revealed or posted within this market's timeframe will not qualify. A qualifying mural or street artwork must be outdoors on a structure or surface other than a canvas. Paintings on canvases or other surfaces designed for art, such as paper or board, will not qualify.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Will Banksy create a new mural or street artwork by December 31? | 79% YES | 21% NO |
Banksy, the Bristol-based street artist, has maintained an active practice of creating authenticated murals and outdoor works despite operating anonymously. The market settles affirmatively if he produces and authenticates a new mural or street artwork by year-end 2026—works must be created within the timeframe, not merely revealed, and must exist outdoors on permanent structures rather than portable surfaces. The 79% implied probability on Polymarket's order book reflects confidence in his continued output over the next two years, though this represents a meaningful tail risk of inactivity or authentication disputes.
Banksy's historical pattern shows sporadic but consistent mural creation, with notable works appearing in locations including London, New York, and internationally. He typically authenticates works through his Instagram account or official representatives, though disputes over attribution have occasionally complicated settlement of similar markets. The artist has produced multiple pieces annually in recent years, including works in 2023 and 2024, establishing a baseline expectation for continued activity. His practice of responding to current events and social commentary suggests ongoing motivation for public works.
Traders should monitor Banksy's social media channels and art news outlets for announcements of new projects. His authentication methods remain consistent but occasionally delayed, creating potential settlement ambiguity. Geopolitical events and urban development in his typical working locations could influence opportunity and visibility. The two-year window provides substantial time for production, though any extended hiatus or shift toward exclusively private commissions would pressure the current probability downward.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
