Market context

The New York Yankees and Boston Red Sox face off in an MLB game on 26 June at 7:10pm ET, with the Yankees favoured to win. While the prediction market currently implies a 0% chance for the Yankees, this stark divergence clashes with sportsbook lines and analyst consensus that heavily favour New York. FanDuel lists the Yankees at -112 moneyline with a 58.1% win probability, while DraftKings prices them at -118, and Rotoworld’s model projects a Yankees victory with an 8.5-run total over as the primary bet [1][2].

Historically, such extreme prediction-market underpricing against a clear favourite often signals a data error or a misunderstanding of the resolution rules rather than a genuine market inefficiency. Comparable cases in MLB markets show that when sportsbooks and models align on a 58–60% win probability for one side, a 0% implied probability on a parallel platform is anomalous and usually corrected once the discrepancy is flagged by traders. The Yankees’ 90-run scoring advantage, 4–2 season-series lead, and superior pitching profile further undermine the 0% claim [3].

Traders should monitor the official starting pitchers and any late injury reports before the 7:10pm ET start, as these are the primary catalysts for line movement. Recent line data shows the Yankees’ moneyline shifting from -120 to -115 following the Red Sox’s 6–3 win the previous night, indicating the market is adjusting for recent form [3]. With the total set at 8.5–9 runs and extreme over-dollar tracking, the game’s run environment is a key dependency to watch alongside the final pitching announcements [1][3].

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.
