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).Dallas Mavericks forward Cooper Flagg's dominance as the No. 1 overall pick in the 2025 NBA Draft has propelled him to a 100% implied probability on Polymarket for 2025-26 Kia NBA Rookie of the Year, cemented by yesterday's official announcement earning him the Wilt Chamberlain Trophy over former Duke teammate Kon Knueppel in a tight voting battle (56-44 first-place votes). Flagg's record-setting rookie campaign—21.0 PPG, 6.7 RPG, 4.5 APG, 1.2 SPG, including the youngest 50-point game in NBA history—outshone a stacked class amid late-season surges like his 51-point outburst. While Knueppel led in threes, Flagg's all-around impact and Mavericks' contention sealed trader consensus; realistic challenges now limited to unprecedented recount or eligibility issues.
