PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Market Type Mismatch: Kalshi provides run-total thresholds (binary Yes/No on collective scoring), while Polymarket provides a three-way winner market (Royals / Nationals / Draw). These measure different underlying events and require separate resolution logic.Hero tip: Kalshi and Polymarket are not interchangeable. A high-scoring tie resolves differently on each platform. Use Polymarket to bet on the winner after 5 innings; use Kalshi to bet on total run volume. Cross-platform arbitrage is not possible here.

Critical divergence points:

  • Kalshi: Seven binary run-total markets (over/under 0.5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5 combined runs in first 5 innings). Each resolves Yes if the threshold is exceeded, No otherwise. No winner or tie logic. Key quote: 'If Kansas City and Washington collectively score more than [X] runs in the first 5 innings... then the market resolves to Yes.'
  • Polymarket: Three-way outcome market: resolves to Royals, Nationals, or Draw based on who is ahead (or tied) at the end of the 5th inning. Includes postponement (market stays open) and cancellation (50-50 split if no makeup game). Key quote: 'This market will resolve to "Kansas City Royals" if the Kansas City Royals is winning... "Washington Nationals" if Washington is winning... "Draw" if the game is tied.'

Kalshi

Resolution is based on the combined runs scored by both teams through the completion of the fifth inning of the Kansas City vs Washington game originally scheduled for June 16, 2026 at 6:45 PM EDT. Each market outcome corresponds to a specific run threshold (0.5, 1.5, 2.5, 3.5, 4.5, 5.5, or 6.5 runs), and resolves to Yes if the combined total exceeds that threshold. If the game is postponed or delayed, the market remains open and closes after the rescheduled game concludes within two days.

Frequently asked questions

Prediction markets and sportsbooks price risk differently. Sportsbooks set odds to balance their book and lock in profit margins, while prediction markets reflect pure trader consensus—what participants genuinely believe will happen. This market aggregates bets from thousands of independent traders rather than a single operator, often surfacing sharper, less biased probabilities. However, sportsbook odds may incorporate live injury reports or late-breaking news faster. Comparing both sources helps you identify mispricings and make more informed decisions on first-five-inning outcomes.

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 uses distinct contract designs: Polymarket may frame the outcome as a binary yes/no on a specific scenario, while Kalshi structures it around run totals or head-to-head matchups. User demographics, liquidity depth, and fee structures also vary between platforms, causing traders to price the same underlying event differently. Additionally, one platform may attract sharper bettors in baseball markets, or have lower trading costs that encourage tighter spreads. Monitoring both helps you identify arbitrage opportunities and understand which platform's pricing aligns with your own view.

Lineup announcements, starting pitcher changes, and injury reports can shift odds significantly before first pitch. Weather conditions—wind speed and temperature—affect ball carry and scoring pace in the early innings. Bullpen depth and recent form of both teams' relievers matter, since the first five innings often feature starter transitions. Public betting action and sharp money flowing into one side can also trigger rapid repricing. Monitor team news, weather forecasts, and live order-book activity on both platforms to catch momentum shifts before the game starts.
