PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's game winner market contains a logical contradiction where both possible outcomes (Boston win and Los Angeles win) resolve to Yes, making the market unresolvable. Polymarket and Predict maintain consistent binary logic.Hero tip: Do not trade on Kalshi's game winner market. The resolution logic guarantees Yes regardless of game outcome, eliminating price discovery. Polymarket and Predict offer sound binary markets with proper edge-case handling for postponements and cancellations.

Critical divergence points:

  • Polymarket: Binary winner market resolves to team name (Red Sox or Angels). Postponement keeps market open; cancellation/tie resolves 50-50. Primary source: official MLB statistics within 24 hours, fallback to credible reporting consensus.
  • Kalshi: CRITICAL FLAW: Market states both 'If Los Angeles A wins... resolves to Yes' AND 'If Boston wins... resolves to Yes'. This logical contradiction means the market always resolves Yes, regardless of actual game outcome.
  • Predict: Binary winner market resolves to team name (Red Sox or Angels). Postponement keeps market open; cancellation/tie resolves 50-50. Primary source: official MLB statistics within 24 hours, fallback to credible reporting consensus.
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 sports events through different mechanisms. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets rely on trader consensus—buy-and-sell pressure from participants with real money at stake. Prediction market odds often reflect sharper, more dynamic pricing because traders can enter and exit positions continuously, whereas sportsbook lines update less frequently. This market's prices on Polymarket and Kalshi may diverge from major sportsbooks, especially as new information emerges closer to game time. Comparing both sources helps identify value and understand where smart money is positioned.

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. Polymarket and Predict attract different trader demographics, liquidity pools, and fee structures, all of which influence how prices settle. Polymarket's larger user base and higher volume can produce tighter, more efficient pricing, while Predict may see less frequent updates or different risk appetites among its participants. Geographic restrictions, platform UI design, and promotional incentives also shape which outcomes traders favor on each venue. These differences create temporary arbitrage opportunities; savvy traders monitor both platforms to exploit pricing gaps before they close.

Key catalysts include injury announcements to star players, bullpen availability, recent team form, and weather conditions at game time. Lineup changes, trades, or unexpected roster moves can shift odds significantly. Public betting action and sharp money flows on sportsbooks often precede prediction market moves, so monitoring line movement there offers early signals. Pregame commentary from analysts and real-time updates during warm-ups can also trigger repricing. Close attention to team news and Vegas action will help traders anticipate and capitalize on price shifts leading up to first pitch.
