Resolution criteria on PolyGram: This market will resolve to “Yes” if Zohran Mamdani ceases to be the mayor of New York City for any period of time between taking office and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. If Zohran Mamdani does not take office as the 111th Mayor of New York City, succeeding Eric Adams, as currently scheduled for January 1, 2026, by February 1, 2026, 11:59 PM ET this market will resolve to “Yes.” An announcement of Zohran Mamdani's resignation/removal before this market's end date will immediately resolve this market to "Yes", regardless of when the announced resignation/removal goes into effect.
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
| Zohran Mamdani out as mayor of NYC before 2027? | 8% YES | 92% NO |
Zohran Mamdani, a New York State assemblymember representing parts of Brooklyn and Queens, won the 2025 mayoral election and is scheduled to take office as New York City's 111th mayor on 1 January 2026. This market tests whether he will remain in that position through the end of 2026, with resolution triggered if he fails to take office by 1 February 2026 or announces resignation or removal before the settlement date. The current order book on Polymarket implies an 8% probability of early departure, reflecting base-rate expectations for mayoral continuity in major US cities.
Historical precedent suggests sitting mayors rarely exit office within their first year absent serious scandal or health crisis. Eric Adams, Mamdani's predecessor, faced federal indictment in September 2023 but remained in office through his term. Jimmy Carter's brief mayoral tenure in Atlanta (1964–1970) and Michael Bloomberg's three full terms in New York (2002–2013) demonstrate that once inaugurated, mayors typically serve their intended duration. The 8% probability appears calibrated to account for unexpected legal jeopardy, severe health events, or unforeseen political circumstances rather than routine governance challenges.
Traders should monitor developments in Mamdani's background vetting, any federal or state investigations affecting him, and his transition team's operational readiness ahead of the January inauguration. The New York Times and Gothamist have covered his campaign and policy positions; any adverse reporting or legal filings would likely move the probability upward. The tight window between election and inauguration (roughly five weeks) also creates technical risk around swearing-in procedures, though this remains a low-probability scenario.
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.
The mechanics for trading "Zohran Mamdani out as mayor of NYC before 2027?" are the same as any other PolyGram political event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$50K in lifetime turnover and $24K of resting liquidity puts this market in the below the median by volume for politics contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.
The market has been open for 6 months — long enough that the order book is mature and price is well-anchored to fundamentals.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
As of today, traders on Polymarket price this outcome at 8%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
