New York Yankees vs. Boston Red Sox

Market context

The underlying event is an MLB match at Fenway Park on Saturday, 27 June 2026, where the New York Yankees face the Boston Red Sox at 1:10 PM ET. The Yankees hold a 48–32 record, while the Red Sox sit at 33–46, reflecting a clear disparity in season performance [2]. Despite this, the crowd-implied probability for a Yankees win is only 8% YES, a figure that demands scrutiny against historical precedents where strong teams underperformed due to pitching rotations or late-injury shocks. In comparable cases, such as the 2024 series where the Red Sox won six to one after taking the first two games, crowd probabilities often lagged behind actual outcomes until final lineups were confirmed [1]. This suggests the current 8% may reflect uncertainty over probable pitchers rather than pure team strength.

Traders should monitor the probable pitcher announcements and any late roster changes before the 1:10 PM ET start, as these are the primary catalysts for probability shifts. ESPN’s live coverage will provide real-time updates on lineups and in-game performance, which are critical for assessing settlement risk [3]. The game is broadcast on ABC/ESPN, ensuring wide visibility and rapid data dissemination [2]. Additionally, the settlement window ends 4 July 2026, meaning any postponement will extend the market’s open status until completion, adding a dependency on weather or scheduling delays. The no-KYC threshold up to $1,500 enhances accessibility for UK and EU traders, allowing participation without identity verification, though German GlüStV and US CFTC regulations may impose indirect compliance requirements for larger volumes. This market remains open to retail participants under these frameworks, provided they adhere to local tax and regulatory obligations.

Methodology

This page reviews New York Yankees vs. Boston Red Sox across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
