New York Mets vs. Cleveland Guardians

Platform comparison

Market context

Polymarket’s contract is trading at **48% YES** for the Mets, so the market is close to a coin flip rather than leaning decisively on either side. Because it settles in **USDC** on **Polygon** through conditional tokens, the price is the crowd’s live estimate of whether New York will be the official winner once MLB’s final result is recorded, with postponements left open until the game is actually completed and cancellations or ties resolving 50-50.

That pricing sits neatly between the teams’ recent form and the broader season profile. Cleveland has been the steadier side in the standings and had already taken the season series edge in comparable head-to-head history, while New York has shown more volatility on the road. In the immediate run-up to this game, the Mets had just beaten the Guardians **6-2** in the series opener, and ESPN listed Cleveland as a modest moneyline favourite for the next matchup, which is consistent with a market that keeps the Mets below 50% but not far from parity.[2][3]

For traders, the key catalysts are the confirmed starting pitchers, late lineup changes, and any schedule movement that could affect whether the game is played as listed at **1:10 pm ET**. The market’s resolution depends on the official final statistics, so a rainout, suspension, or doubleheader rearrangement matters more here than normal day-of chatter. Recent previews also pointed to Cleveland’s stronger recent run prevention and New York’s mixed offensive output, which helps explain why the contract has not moved far from the middle despite the Mets’ latest win.[3][13][9]

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 PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
