Sports moneyline - resolves based on official game outcome per ProphetX Prediction Rules
The outcomes listed above show how traders are pricing this question. Compare outcome prices from Kalshi, Polymarket US, Polymarket, ProphetX in one place. Each price reflects the market’s implied probability, not a guaranteed result. This event is archived; prices shown are historical.
The last available prices are Kansas City Royals: 99.0¢ on Kalshi, 99.9¢ on Polymarket, 97.6¢ on ProphetX, 99.5¢ on Polymarket US; Detroit Tigers: 1.0¢ on Kalshi, 99.9¢ on Polymarket, 3.3¢ on ProphetX, 0.5¢ on Polymarket US. Prices are quoted in cents per $1 share. Check the venue for executable prices and available liquidity. The last available price is not necessarily the final settlement price.
The largest price difference shown across venues is 99.4 percentage points. Venues have different traders, liquidity and fees, so their prices can differ. A price gap alone does not establish an executable arbitrage opportunity; compare settlement rules and the actual buy and sell prices.
For example, Kansas City Royals at 99.0¢ implies about a 99.0% chance. For a standard $1 contract, a share pays $1 if its outcome settles as correct and $0 if it settles as incorrect. A winning share bought at 40¢ earns 60¢ before fees. Check each venue’s settlement rules, fees and eligibility before trading. Historical prices alone do not identify the winning outcome.
