PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Scope divergence: Kalshi measures overtime occurrence (binary), while Polymarket measures game winner (ternary with cancellation). Both reference the same June 20, 2026 game but resolve on orthogonal outcomes.Hero tip: These markets are not opposites or hedges. Overtime can occur with either team winning, and either team can win without overtime. Trade each market on its own merits. Correlate outcomes only if you have independent conviction on both overtime likelihood and winner probability.

Critical divergence points:

  • Kalshi: Binary overtime market. Resolves YES if the game goes to overtime, NO if it ends in regulation. Quote: 'If Indiana and Atlanta go to overtime in the Indiana vs Atlanta women's professional basketball game originally scheduled for Jun 20, 2026, then the market resolves to Yes.' No mention of winner; overtime is the sole resolution criterion.
  • Polymarket: Ternary winner market with cancellation clause. Resolves to 'Indiana Fever' or 'Atlanta Dream' based on final score (including overtime). Quote: 'The result will be determined based on the final score including any overtime periods.' Overtime is incorporated into final score but is not the primary resolution metric. Cancellation resolves 50-50.

Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet.

Frequently asked questions

Prediction markets and traditional sportsbooks price outcomes differently because they operate on distinct mechanisms. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets let traders freely buy and sell shares, allowing prices to float based on supply and demand. This market's odds may diverge from your local sportsbook, especially as new information emerges. Prediction markets often react faster to breaking news and tend to reflect sharper, less-constrained pricing since there's no house edge built in.

Polymarket and Kalshi can show different odds on the same event for several reasons. 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 has its own liquidity pools, user base, and fee structures, which influence how quickly prices adjust. Geographic restrictions, platform-specific trading incentives, and differences in order-book depth can all create temporary spreads. Arbitrage traders often exploit these gaps, but friction costs and withdrawal delays mean small divergences persist. Monitoring both venues helps you spot value and understand where the broader market consensus is strongest.

Injury reports, roster changes, and recent team performance are key catalysts that shift odds in this market. If either team announces a significant player absence or makes a late trade, expect sharp price movement. Public betting trends, expert predictions, and media coverage can also influence trader sentiment. Preseason form, head-to-head history, and home-court advantage all factor into positioning. As game day approaches, late-breaking news—weather, lineup confirmations, or momentum shifts—often triggers final repricing before the market locks.
