Divergence Detected

Issue: Fundamental divergence in settlement criteria between marketsHero tip: Traders should be cautious due to fundamentally different resolution criteria. A match lasting 22+ games could still result in a 50-50 outcome on Polymarket if the match ends in a walkover or cancellation.

Critical divergence points:

  • limitless: Resolves to YES if total games equal or exceed 22, NO otherwise. 50-50 if match begins but is not completed or canceled before play begins. Key quote: This market will resolve to YES if the total number of games completed across all sets equals or exceeds 22.
  • Polymarket: Resolves to Elise Mertens or Naomi Osaka based on who advances. 50-50 if match is canceled, ends in a tie, delayed beyond 7 days, or ends in a walkover. Key quote: This market will resolve to 'Elise Mertens' if Elise Mertens advances against Naomi Osaka.
