Market context

The Boston Red Sox face the Colorado Rockies at Coors Field in Denver on 22 June 2026, with the game scheduled to begin at 8:40 PM ET. This single MLB contest determines the market outcome: a Red Sox win resolves to YES, while a Rockies win resolves to NO. If the match is postponed, the market remains open until completion; a full cancellation or tie settles at 50-50.

Historical precedent frames the current 85% YES implied probability. Last season, the Red Sox swept a three-game set against the Rockies, outscoring them 29-7[5]. Both clubs now sit near the bottom of their standings, with the Red Sox at 31-44 and the Rockies at 30-48[1]. Sportsbooks show a divergence: ESPN lists the Red Sox at -137 for the June 22 game, while the June 23 matchup features Sonny Gray at -168, suggesting a 58.4% win probability for Boston in that later contest[1][2]. The prediction market’s 85% figure significantly exceeds these sportsbook lines, indicating a notable divergence from analyst consensus.

Traders should monitor pitching announcements and lineup changes, particularly given the high-scoring nature of Coors Field. The June 22 game total is set at 11.5 runs, with the over favoured at -117[3]. Ryan Feltner, who has a 3.86 ERA in four starts since returning from the injured list, remains a key dependency for the Rockies[5]. Any late injury updates to either starting pitcher could shift the odds, as the market currently prices in a strong Red Sox advantage despite the Rockies’ home-field context.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
