PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket and Kalshi use different market structures (three separate binaries vs. single three-outcome market) with conflicting cancellation rules for the Draw/Tie outcome. Kalshi's cancellation protocol is not explicitly defined.Hero tip: Monitor for match postponement or cancellation announcements. If canceled with no makeup, Polymarket's Draw market pays YES while Start/Rosenborg pay NO—a rare asymmetry. Kalshi traders should request explicit cancellation guidance from the platform before the event date.

Critical divergence points:

  • Polymarket: Three separate binary markets (Start Win / Draw / Rosenborg Win). Draw market uniquely resolves YES on cancellation with no makeup. Start and Rosenborg markets resolve NO on cancellation. Resolution source: official Eliteserien statistics within 2 hours, or credible reporting consensus. Key Quote: Draw market—'If the game is canceled entirely, with no make-up game, this market will resolve to Yes.'
  • Kalshi: Single market with three mutually exclusive outcomes (Start Win / Rosenborg Win / Tie). Cancellation protocol not explicitly stated. Resolution scope: 90 minutes plus stoppage time only. Key Quote: 'If Tie is the result of the Start vs Rosenborg professional Eliteserien soccer game originally scheduled for Jul 18, 2026 after 90 minutes plus stoppage time, then the market 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.

Frequently asked questions

Prediction markets and traditional sportsbooks price events differently because they operate under distinct mechanisms. Sportsbooks set odds to balance their book and lock in profit margins, while prediction markets like those tracked here rely on trader consensus—the collective intelligence of participants buying and selling shares. Prediction market prices often reflect real-time information and can adjust faster than sportsbook lines, especially as new data emerges. However, sportsbook odds may incorporate sharper professional betting activity. Comparing the two can reveal value opportunities and help you understand how different groups assess the likelihood of this match's outcome.

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 prices to diverge even when tracking the same event. Polymarket and Kalshi may have different user bases with varying risk appetites, information access, or trading strategies. Liquidity depth varies between venues, so large trades can move prices differently on each platform. Additionally, platform-specific rules, settlement timelines, or promotional incentives can influence how traders price this market. These differences typically narrow as the event approaches and arbitrage traders exploit gaps, but temporary spreads are normal and create opportunities for informed traders.
