PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket and Kalshi offer structurally different market types on the same underlying game. Polymarket is a moneyline (winner-take-all) market, while Kalshi provides multiple spread-based markets. Resolution logic is not contradictory but operates on different settlement dimensions.Hero tip: Do not treat these as redundant markets. Polymarket tells you who wins; Kalshi tells you by how much. A Toronto moneyline win on Polymarket could resolve Yes or No on any given Kalshi spread depending on the final margin. Use Kalshi spreads to refine your confidence in margin of victory, and Polymarket to isolate winner probability. Diversify across both if you have strong conviction on both the winner and the margin.

Critical divergence points:

  • Polymarket: Binary moneyline market. Resolves to 'Toronto Raptors' if Toronto wins or 'Boston Celtics' if Boston wins, regardless of margin. If game is canceled with no makeup, resolves 50-50. Final score including overtime determines outcome.
  • Kalshi: Nine independent spread markets. Each market resolves Yes if the specified margin condition is met (e.g., 'Toronto wins by >1.5 points' or 'Boston wins by >3.5 points'). Each spread is a separate Yes/No resolution, not a single outcome.
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.

Polymarket

In the upcoming NBA Summer League game, scheduled for July 10 at 9:00PM ET: If the Toronto Raptors win, the market will resolve to "Toronto Raptors". If the Boston Celtics win, the market will resolve to "Boston Celtics". If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, this market will resolve 50-50. The result will be determined based on the final score including any overtime periods.

Kalshi

Resolution is determined by the final point differential in the Boston vs Toronto game. For Toronto victories, the market resolves Yes if Toronto wins by more than 1.5, 3.5, 6.5, 9.5, or 12.5 points. For Boston victories, the market resolves Yes if Boston wins by more than 1.5, 3.5, 6.5, or 9.5 points. Each spread threshold represents a distinct outcome; only the applicable spread(s) matching the actual final margin will resolve to Yes. Games that end in a tie or are postponed/cancelled may have different resolution procedures as specified in secondary rules.

Frequently asked questions

Prediction markets like Polymarket and Kalshi operate on peer-to-peer trading rather than fixed odds set by a sportsbook. Instead of a bookmaker managing margins, traders themselves determine prices through supply and demand, often reflecting sharper, crowd-sourced estimates. Sportsbooks typically build in a margin and may move lines based on liability management; prediction markets adjust continuously as new information arrives. This market's odds may diverge from traditional sportsbook lines, especially as the game approaches and more data becomes available.

Polymarket and Kalshi can price this market differently due to variations in their user bases, contract structures, and liquidity pools. 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 may attract traders with distinct information sets or risk tolerances, and differences in how each frames the outcome—such as margin thresholds or payout mechanics—can create price gaps. Arbitrage opportunities sometimes emerge when one platform's odds diverge significantly from the other, incentivizing traders to exploit the spread until prices converge.

Key catalysts include roster announcements, player injuries or absences, recent Summer League performance trends, and coaching decisions about lineup rotation. Media coverage highlighting either team's prospects or draft implications can shift trader sentiment. As game day approaches, weather conditions, venue factors, and late-breaking team news may trigger price movement. Trading volume often spikes closer to tip-off as new information crystallizes and traders refine their positions ahead of the final outcome.
