Resolution criteria on PolyGram: This market will resolve according to the player that finishes the 2026 WNBA regular season with the highest rebounds per game average of any qualified player. In the event of a tie for the highest rebounds per game average, this market will resolve in favor of the player who appeared in the greater number of games. If the tied players also played the same number of games, the market will resolve in favor of the player whose listed last name comes first alphabetically. Qualification for inclusion in official WNBA leaderboards (such as minimum games or statistical thresholds) will be determined according to WNBA rules and applied exactly as reflected in the official leaderboard.
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.

The 2026 WNBA regular season will determine which player finishes with the highest rebounds per game average among qualified competitors. The market currently reflects a 51% implied probability for the YES outcome, formed through Polymarket's order book as traders price the likelihood that a player will achieve a rebounds-per-game leader finish within the specified parameters. Settlement occurs on 24 September 2026, following the conclusion of the regular season.
Historically, WNBA rebounding leadership has concentrated among post players and versatile forwards, with centres typically dominating the category. Brittney Griner, Sylvia Fowles, and DeWanna Bonner have held this distinction in recent seasons, with winning averages typically ranging between 9 and 11 rebounds per game. The current 51% probability suggests meaningful uncertainty about whether the favourite candidate will sustain the necessary volume and efficiency through a full season, or whether injury, reduced minutes, or competitive pressure from emerging talent could alter the outcome.
Traders should monitor preseason roster announcements and training camp reports through spring 2026, as team construction changes directly affect individual rebounding opportunities. The WNBA draft in April 2026 and subsequent free agency period will clarify which players have access to sufficient possessions and minutes to contend for the leaderboard. Injury reports during the regular season will prove critical, given that qualification thresholds may eliminate borderline candidates, whilst the tiebreaker provisions—favouring games played, then alphabetical surname ordering—create specific edge cases worth tracking as the season concludes.
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.
