Baltimore Orioles vs. Minnesota Twins

Platform comparison

Market context

The Baltimore Orioles and Minnesota Twins are playing a regular-season MLB game, and this market settles on whichever club is credited with the win on the official final score. A **YES** share means Baltimore wins; a **NO** share means Minnesota wins. If the game is postponed, the market stays open until the makeup is played; if it is cancelled outright or ends tied, it resolves 50-50 rather than to either side.

The current crowd-implied **73% YES** price is noticeably higher than the latest live game estimate, where ESPN’s matchup page showed Baltimore at about **47.6%** before the contest, a reminder that prediction-market prices can move faster than one-off model snapshots.[1] The teams also came in with a mixed recent head-to-head record: TeamRankings lists Baltimore ahead **8-7** over the last three seasons, but StatMuse shows the Orioles have gone only **2-8** in their last 10 meetings with Minnesota.[14][16] Earlier this season, they split the first three games of the matchup, with Baltimore winning on 26 March and 29 March and Minnesota taking 28 March.[3][4][6]

For traders, the key catalysts are straightforward: starting pitcher confirmations, any late lineup changes, and weather-related postponement risk, because this market remains live until the game is officially completed. The game was scheduled for **11 August at 7:40 pm ET**, and recent scorelines suggest both clubs have been alternating between short, high-variance results, including Minnesota’s 9-5 win over Baltimore on 10 August and Baltimore’s 10-5 win over Texas the next day.[1][5][9] If the official result is delayed by rain, or if the scheduled game is rescheduled, the payout timing can change even when the teams themselves do not.[1]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
