PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market definition contains a logical contradiction where all three mutually exclusive outcomes (Arizona win, St. Louis win, tie) are mapped to the same resolution (Yes), rendering the market fundamentally unresolvable. Polymarket correctly defines three distinct outcomes.Hero tip: Do not trade Kalshi's version of this market in its current form. The Polymarket structure is logically sound: Arizona Diamondbacks resolves if Arizona leads after 5 innings, St. Louis Cardinals resolves if St. Louis leads after 5 innings, and Draw resolves if tied. Kalshi's market as stated cannot distinguish between outcomes.

Critical divergence points:

  • Kalshi: Market states: 'If Arizona and St. Louis tie...then Yes. If Arizona wins...then Yes. If St. Louis wins...then Yes.' All three exhaustive outcomes map to identical resolution, creating logical impossibility. No No outcome is defined.
  • Polymarket: Three distinct binary outcomes: Arizona Diamondbacks (Arizona leads after 5 innings), St. Louis Cardinals (St. Louis leads after 5 innings), Draw (tied after 5 innings). Includes explicit handling for postponements (market remains open) and cancellations (50-50 split). Primary source is official MLB statistics.

Frequently asked questions

The First 5 Innings Winner market aggregates trader positions across Polymarket and Kalshi, tracking which team bettors expect to lead after the first five innings of the Arizona Diamondbacks versus St. Louis Cardinals matchup. This market reflects real-time consensus pricing as traders buy and sell shares based on team strength, weather, pitching matchups, and other early-game factors. Cross-platform volume and odds movements reveal how prediction market participants assess the likelihood of each outcome, offering a dynamic alternative to traditional sportsbook lines for the opening half of play.

Prediction markets and sportsbooks price outcomes differently because they operate under distinct incentive structures. Sportsbooks set odds to balance action and lock in profit margins, while prediction markets aggregate decentralized trader beliefs through continuous price discovery. This market's odds on Polymarket and Kalshi may diverge from major sportsbooks because traders are directly exposed to the outcome rather than earning a commission. Prediction market prices often reflect sharper, more reactive adjustments to breaking news—such as late-inning pitcher changes or injury updates—making them useful benchmarks for comparing against traditional betting lines.

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 operates under different contract structures, liquidity pools, and user bases, which can create temporary price gaps. Polymarket may frame the outcome as a binary yes/no on St. Louis winning the first five innings, while Kalshi might emphasize a tie scenario, attracting different trader strategies. Liquidity depth, trading fees, and the timing of large orders also influence how quickly prices adjust on each venue. These differences typically narrow as arbitrageurs exploit spreads, but they can persist if one platform attracts more informed flow or if contract specifications genuinely appeal to different market segments.

Key catalysts include lineup announcements, starting pitcher confirmations, and any last-minute roster changes or injuries to star players. Weather conditions at game time—wind direction, temperature, and humidity—can significantly affect early-inning scoring dynamics. Betting market activity and sharp money flowing into one side may also shift prices as professional traders position ahead of first pitch. Additionally, pre-game commentary from analysts, recent team performance trends, and head-to-head matchup history can trigger repricing as traders reassess their edge. Monitor sports news feeds and platform activity closely in the hours leading up to game time for the most volatile price movements.
