Prediction market · Polymarket

Overview

This market will resolve to “Over” if more than 4.5 games are played during the 2026 NBA Playoffs First Round series between the Philadelphia 76ers and Boston Celtics. Otherwise, this market will resolve to “Under”. If a partial series is played and not completed by May 31, 2026, 11:59 PM ET, this market will resolve according to the number of games played. If the 2026 NBA Playoffs are cancelled, postponed after May 31, 2026, 11:59 PM ET, or there is otherwise no winner declared within that timeframe, this market will resolve to 50-50. The resolution source for this market will be official information from the NBA; however, a consensus of credible reporting may also be used.

Edgecombe, and Boston's 108-100 Game 3 grinder from Jayson Tatum and Jaylen Brown's 25 points each—Game 4 today in Philadelphia mathematically ensures at least five total games regardless of the winner, driving trader consensus to 99.7% implied probability on Over 4.5. Jayson Tatum's strong postseason return from injury has fueled Boston's edge, but Philadelphia's home-court resilience keeps it competitive. Only an unprecedented cancellation, forfeiture, or mass injury outbreak could derail this, though such scenarios remain highly improbable.",
