Resolution criteria on PolyGram: This is a market to predict which player will win the 2025–26 NBA Rookie of the Year award. This market will resolve to "Yes" if the listed player is officially named the 2025–26 NBA Rookie of the Year. Otherwise, it will resolve to "No". If the award is not announced by December 31, 2026, this market will resolve to "Other". The primary resolution source will be official information from the NBA (https://www.nba.com).
Real-money prediction markets aggregate live odds from thousands of traders, surfacing a sharper probability than any single forecast. Odds will populate live once the order book fills (the resolution date has passed — final payout is being settled via UMA oracle).

The 2025–26 NBA season will crown a Rookie of the Year following the conclusion of the regular season and playoffs. The award recognises the most outstanding first-year player across the league, determined by a voting panel of media members and fan participation. The settlement window closes on 18 May 2026, allowing sufficient time for the NBA to announce the winner, typically occurring in June during the awards ceremony preceding the Finals.
The 0% implied probability on Polymarket's order book reflects either the absence of meaningful liquidity on this particular contract or a market consensus that the listed player carries negligible chances of winning. Historical context matters here: Rookie of the Year voting has historically favoured players on playoff teams with high usage rates and statistical prominence. Recent winners such as Paolo Banchero (2022–23) and Scottie Barnes (2021–22) were lottery picks with immediate offensive responsibilities. The current probability formation suggests traders view this contract's candidate as unlikely to meet those benchmarks—either due to draft position, team circumstances, or expected playing time.
Traders should monitor the 2025–26 season's statistical leaders among first-year players, playoff seeding outcomes, and any injury developments that might alter rookie prominence. The NBA typically announces the award in early June, with voting occurring in May. Media narratives around breakout rookies often solidify during the final weeks of the regular season, making late-April and early-May reporting critical for assessing shifting probabilities before settlement.
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.

If a dispute is filed inside the two-hour window, the outcome escalates to UMA token-holder voting, which extends settlement by roughly 48 hours. This particular market has no public resolution feed listed; disputes here are more likely if the underlying outcome is subject to interpretation, in which case the UMA token-vote arbitrates the wording of the original market question.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose. For "NBA Rookie of the Year", the considerations above apply directly — Trade size should reflect the binary nature of the payoff: even a 70% probability event resolves NO 30% of the time, so any single position can lose 100% of staked capital.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
