PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's resolution criteria contain a logical contradiction: both possible game outcomes (Fenerbahce win and Besiktas win) are mapped to YES resolution, leaving no valid NO outcome. This makes the market fundamentally unresolvable as a binary contract.Hero tip: Treat Kalshi's market as data-integrity failure until clarified by the platform. Use Polymarket as your authoritative settlement reference. Kalshi likely intended to specify one team as YES and the other as NO, but the current wording creates an impossible settlement scenario.

Critical divergence points:

  • Polymarket: Binary winner-take-all with clear mutually exclusive outcomes. Resolves to team name of winner. Postponement keeps market open; cancellation with no makeup resolves 50-50. Source: TBL.org.tr (Turkish Basketball League official). Key quote: 'If the Fenerbahce win, the market will resolve to Fenerbahce. If the Besiktas win, the market will resolve to Besiktas.'
  • Kalshi: Contradictory dual YES mapping. Both Fenerbahce win and Besiktas win conditions resolve to YES, with no specified NO outcome. No handling of postponement or cancellation. Key quote: 'If Fenerbahce Istanbul wins...resolves to Yes. If Besiktas JK wins...resolves to Yes.'
Our 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.

Polymarket

In the upcoming Turkey BSL game, scheduled for June 15 at 1:00PM ET: If the Fenerbahce win, the market will resolve to "Fenerbahce". If the Besiktas win, the market will resolve to "Besiktas". If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, this market will resolve 50-50. The result will be determined based on the final score including any overtime periods.

Kalshi

This event covers a professional Turkey BSL basketball game originally scheduled for June 15, 2026 at 1:00 PM EDT. Resolution is based on the final outcome of the game, with each team having a corresponding market outcome. If the game is postponed or delayed, the market remains open and resolves after the rescheduled game concludes, provided the reschedule occurs within two weeks. Should the game be cancelled entirely or rescheduled beyond two weeks, the market resolves to a fair price for each team in accordance with standard resolution procedures.

Frequently asked questions

Prediction markets like these operate on continuous trader-set pricing rather than fixed sportsbook lines. Traders buy and sell shares reflecting their belief in each outcome, pushing prices toward true probability. Unlike traditional sportsbooks, prediction markets often lack built-in margins, making them more efficient at pricing. However, sportsbooks may move faster on breaking news or injury reports, while prediction markets aggregate dispersed information over time. Both serve as useful benchmarks, though prediction markets tend to reflect longer-term consensus.

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. Polymarket may draw more international participants, while Kalshi's regulatory framework appeals to US-focused traders. Order flow timing, market depth, and recent activity can cause temporary price gaps. Additionally, platform-specific rules around trading hours or settlement verification sometimes create arbitrage opportunities that take time to close. These differences typically narrow as informed traders exploit mispricings.

Key injury announcements, team lineup changes, or managerial decisions can shift odds significantly. Recent form, head-to-head records, and league standings often influence trader sentiment in the days before kickoff. Weather conditions, venue factors, and any off-field controversies may also trigger repricing. Major betting syndicates entering the market can move prices sharply. As the match date approaches, late-breaking news—such as player suspensions or tactical shifts—typically drives the most volatile swings in this market.
