Description

This event group covers prediction markets for the winner of the 2026 Women's BNP Paribas Open (Indian Wells), a major professional tennis tournament scheduled for March 1-15, 2026.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms use identical resolution logic: a Yes/No outcome for each listed player based on whether that player wins the 2026 Women's BNP Paribas Open Singles Championship, with consistent handling of cancellation and delay scenarios.Primary resolution logic: Official BNP Paribas Open website (bnpparibasopen.com) with credible sports reporting as secondary consensus source

Core resolution logic:

  • Market resolves Yes if the specified player wins the 2026 BNP Paribas Open Women's Singles Championship
  • Market resolves No if the specified player does not win the tournament or becomes ineligible per tournament rules
  • Tournament must be completed and a winner declared between March 1-15, 2026
  • Polymarket includes an 'other player' option to capture any winner not explicitly listed

Edge cases & clarifications:

  • Tournament Cancellation: If the 2026 BNP Paribas Open Women's Singles is cancelled entirely, Kalshi markets resolve No; Polymarket resolves Other
  • Tournament Postponement: If the tournament is postponed beyond March 31, 2026, Kalshi markets resolve No; Polymarket resolves Other
  • Player Ineligibility: If a listed player becomes unable to compete per official tournament rules, their market resolves No
  • Unlisted Winner: If a player not on either platform's list wins, Kalshi markets all resolve No; Polymarket's 'other player' market resolves Yes
Timing: Resolution occurs upon official declaration of the 2026 BNP Paribas Open Women's Singles Champion, expected by March 15, 2026, with a hard deadline of March 31, 2026Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.
