Boston Red Sox vs. New York Mets

Platform comparison

Market context

The Boston Red Sox face the New York Mets in a regular-season MLB clash at Citi Field on 10 July, with the market currently pricing a Red Sox win at 43% YES. Historical head-to-head data frames this as a slight underdog spot for Boston; the Red Sox hold a 25–19 all-time advantage but have won just 43.2% of regular-season games against the Mets, while the Mets have posted a 4–2 record in their most recent six matchups [1][2][6]. This divergence suggests the crowd may be overreacting to short-term form, creating a potential value angle for contrarians backing the historically superior Red Sox despite the lower implied probability.

Traders should monitor starting pitcher announcements and any late-injury updates before the 7:15PM ET start, as these are the primary catalysts for probability shifts. The Mets’ higher home-run total (108 vs 80) and slightly better on-base percentage could favour them in a night game at Citi Field, but the Red Sox’s batting average remains competitive at .245 [5]. With the settlement window open until 17 July if postponed, liquidity may remain thin until lineups are confirmed, making early positions in the 43% range potentially attractive if the consensus drifts toward the Mets’ recent 54.1% implied win probability [5].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

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?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
