PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket's match completion market excludes forfeits and retirements (resolves No), while Kalshi's match outcome market includes them (resolves Yes if either player wins after a ball is played). Additionally, Polymarket's head-to-head and set markets treat retirements/defaults as advances to the winning player, creating internal inconsistency within Polymarket's own rule set.Hero tip: If the match starts but ends via retirement or default after a ball is played: Kalshi resolves Yes, Polymarket's completion market resolves No, but Polymarket's winner/set markets resolve to the advancing player. Arbitrage or hedge accordingly. For normal completion (no retirement), all platforms converge on the match result.

Critical divergence points:

  • Polymarket: Match Completion market (Q1) requires full completion through normal play. Forfeits, walkovers, retirements, cancellations, ties, and delays beyond 7 days all resolve No. However, head-to-head winner market (Q4) and set winner markets (Q6, Q12) explicitly state that if the match begins and one player advances due to retirement/default/disqualification, the market resolves to the advancing player. This creates an internal contradiction: the completion market says No for retirement, but the winner market says Yes to the advancing player. Key Quote (Completion): 'If a forfeit of any kind occurs, including but not limited to a walkover or retirement, this market will resolve No.' Key Quote (Winner): 'If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, this market will resolve to the player who advances.'
  • Kalshi: Match outcome market resolves Yes if either Aaron Funk or Petros Tsitsipas wins after a ball has been played. No explicit exclusion for retirements, defaults, or disqualifications. The logic is binary: ball played + winner determined = Yes. Key Quote: 'If Aaron Funk wins the Tsitsipas vs Funk professional tennis match in the 2026 M25 Skopje Round of 32 after a ball has been played, then the market resolves to Yes.'

This market will resolve to 'Petros Tsitsipas' if Petros Tsitsipas advances against Aaron Funk. This market will resolve to 'Aaron Funk' if Aaron Funk advances against Petros Tsitsipas. If the match is canceled (not played at all), ends in a tie, or is delayed beyond 7 days from the scheduled date without a winner determined, this market will resolve to 50-50. If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, this market will resolve to the player who advances. If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 50-50. The primary resolution source will be official information from the International Tennis Federation (ITF). A consensus of credible reporting may also be used.

Kalshi

This event covers the professional tennis match between Petros Tsitsipas and Aaron Funk in the 2026 M25 Skopje Round of 32. Resolution requires that a ball has been played in the match. If the match does not occur before play begins due to injury, walkover, forfeiture, or other cancellation, all related markets resolve to $0.50. If a player withdraws or forfeits after the match has started, that player's market resolves to No. Should the match be postponed or delayed, markets remain open and will close following the rescheduled match completion within two weeks. Each player's market resolves to Yes if that player wins the match after a ball has been played.

Frequently asked questions

Prediction markets like Polymarket and Kalshi operate on peer-to-peer trading rather than fixed odds set by a bookmaker. Traders buy and sell shares reflecting their belief in each outcome, creating dynamic prices that often respond faster to breaking news or injury reports than traditional sportsbooks. Because prediction markets aggregate many independent forecasters without a built-in margin, they can sometimes offer tighter odds and sharper pricing than conventional betting platforms, though liquidity varies by event.

Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform attracts different trader demographics, liquidity pools, and fee structures, which can cause temporary price gaps. Polymarket and Kalshi may also frame the same match outcome slightly differently—for instance, one platform might focus on set winners while the other emphasizes match winner—leading to distinct probability curves. Arbitrage traders typically exploit these spreads, but until they do, you may see Polymarket and Kalshi quoting noticeably different odds on identical outcomes.

Key catalysts include injury announcements or withdrawal news affecting either player, recent performance trends from warm-up tournaments, head-to-head history, and court surface conditions at the Skopje venue. Weather forecasts, player fatigue from back-to-back matches, and late lineup changes can all shift trader sentiment. Additionally, movement on related markets—such as odds for other M25 events or ATP rankings implications—may indirectly influence pricing as traders reassess player momentum and confidence.
