Market context

The New York Yankees and Boston Red Sox faced off at Fenway Park on Thursday, 25 June 2026, in a decisive MLB matchup that concluded with the Red Sox securing a 6-3 victory. Caleb Durbin broke a fifth-inning tie with a two-run homer, while Aroldis Chapman closed the game with a final out, cementing Boston’s win over New York [1][2]. This result directly validates the current crowd-implied probability of 0% YES for the Yankees, as the event has already settled in favour of the Red Sox.

Historically, Yankees-Red Sox games at Fenway have often favoured the home side in mid-season clashes, particularly when the Red Sox leverage strong fifth-inning offence and late-game pitching. Comparable cases from the 2024 and 2025 seasons show similar patterns where a tie-breaking homer in the fifth inning shifted momentum decisively, mirroring Durbin’s impact [3][5]. The 0% probability reflects not just speculation but the confirmed outcome, framing the market as one that has already resolved rather than one awaiting future data.

Traders should monitor post-game financial flows and settlement rails, as the book depth for this market is driven by funding channels like Klarna, SEPA, and USDC that facilitate rapid deposits and withdrawals [6]. Recent announcements from MLB confirm the game’s final statistics are official, removing any ambiguity about postponement or cancellation [7]. With the settlement window ending 2 July 2026, the focus now shifts to withdrawal efficiency and the integration of payment on-ramps that sustain liquidity in the aftermath of the result [8].

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.
