This group contains markets related to the Sporting Kansas City vs. Los Angeles FC MLS game on September 12th. Markets cover spreads, over/under goals, and both teams to score, in both the full game and first half. The markets are primarily focused on predicting the final score and goal totals.
More markets for the MLS game, scheduled for September 12 at 8:30 PM ET.
The markets resolve based on whether Kyren Williams accumulates specified thresholds of combined rushing and receiving yards in the San Francisco vs Los Angeles R Pro Football game scheduled for Sep 10, 2026. Each market corresponds to a different yardage threshold (70+, 95+, and 120+). If Williams is active for the game but does not take a snap, the market settles at the fair market price determined before the game starts. Once Williams takes at least one snap—regardless of whether the play is nullified by a penalty—the market resolves based on the total yards he records during the game. These rules apply uniformly across all three markets, with each resolving to 'Yes' only if the respective yardage threshold is met.
Prediction market odds, like those found on Polymarket and Kalshi, often reflect the collective wisdom of a diverse group of traders, potentially offering a different perspective than traditional sportsbooks. Sportsbooks set lines based on their own models and aim to balance action on both sides, while prediction markets allow participants to freely express their beliefs. This can lead to discrepancies, especially when public sentiment strongly diverges from expert opinion. Typically, prediction markets are more accurate than sportsbook odds, but both offer valuable insights for informed decision-making regarding this market.
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. Prices on Polymarket and Kalshi can diverge due to several factors. Each platform attracts a different user base with varying levels of expertise and access to information. Trading volume also plays a role; lower volume can lead to greater price volatility and discrepancies. Furthermore, the specific market structures and fee schedules on each platform can influence trading behavior. For example, Polymarket currently favors Sporting Kansas City 1st Half O/U 1.5 at 99, while Kalshi leans toward Kyren Williams: 95+ rushing and receiving yards combined at n/a, showing differing sentiment.
