Market context

The New York Yankees and Boston Red Sox met at Fenway Park on 25 June 2026 for a 7:10 PM ET MLB contest, a match the Red Sox won 6–3 after Caleb Durbin’s fifth-inning two-run homer broke a tie. Despite the Yankees entering as road favourites with a 63.4% win probability per ESPN[1], the current prediction market shows a 0% implied probability for a Yankees victory, a stark divergence from sportsbook lines where the Yankees sit at -151 moneyline and -1.5 run line across DraftKings[2][5].

Historically, such a 0% market probability for a team with a clear win advantage is anomalous; comparable cases in MLB prediction markets usually reflect either a known postponement, a critical injury not yet priced by bookmakers, or a data error, as the Yankees’ 48–32 record and .600 winning percentage contrast sharply with the Red Sox’s 33–46 slump[1][3]. The 0% figure likely signals a settlement issue rather than a genuine belief in a Red Sox win, given that oddsmakers consistently favour the Yankees by 1.5 runs and set the total at 8–9 points[2][3].

Traders should monitor official MLB announcements for game postponements or cancellations, as the market remains open until completion if delayed, and resolves 50–50 only if cancelled entirely or tied[1]. Recent coverage confirms the game was played and completed, with highlights showing the Red Sox victory[7][8], suggesting the 0% probability may stem from a post-settlement data lag rather than an active trading signal. No new roster changes or weather alerts have been reported since the game’s conclusion, reinforcing that the market’s current state is likely a technical anomaly awaiting correction.

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.
