Miami Marlins vs. Kansas City Royals

Platform comparison

Market context

Miami Marlins vs. Kansas City Royals. The market is currently pricing the outcome at 68% YES, meaning crowd-implied probability sits at that level. Settlement is scheduled for 2026-09-09T23:40:00Z. Unlike a sportsbook, the price you see is set by buyers and sellers competing in a live order book — there is no house edge or bookmaker margin to fade.

Sports outcome markets resolve from official league data once the contest finishes. Pricing typically tightens through the warm-up window as line-ups, weather, and starting-pitcher data become public, then moves on goals or runs in real time.

Watch for the underlying catalysts that move this category: each official announcement, dataset release, or scheduled milestone generally produces a step change in the implied probability. Trades execute instantly on Polygon, and shares pay $1 each at resolution if your side wins.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
