New York Mets vs. Cleveland Guardians

Platform comparison

Market context

The Mets-Guardians game in Cleveland is trading close to a coin flip, with the contract at **48% YES** for New York while the latest sportsbook pricing shown in the search results ranges from a Mets edge to a Guardians edge depending on the book and snapshot. FanDuel’s research page listed the Mets at **-116** and the Guardians at **-102**, implying a slight New York lean, while other snapshots had Cleveland shorter, including **-155** at DraftKings and **-150** in analyst coverage, which is why the market looks tighter than a single line suggests.[4][2][12]

That split is consistent with the wider pattern in recent comparable coverage: prediction models have generally been close, but not uniform. numberFire, cited by FanDuel, projected a **52.5% Mets win probability**, while Dimers and related coverage gave Cleveland roughly **51.5% to 52.8%** to win, with the Mets often rated stronger only on the run line rather than straight up.[4][13][14] In other words, a 48% crowd price for the Mets sits inside the range of current model estimates rather than far from them, and the disagreement is more about which side is marginally overpriced than about a strong directional edge.[8][14]

For traders, the main catalysts are lineup confirmation, starting-pitcher status, and any weather or postponement risk before first pitch, because this market stays open only until the game is completed and would settle 50-50 if it were cancelled or ended in a tie. The settlement window extends to 13 August, so the key dependency is still the actual official result on 6 August rather than any broader series outcome, and late movement in sportsbook moneylines or totals can signal whether one side is attracting sharper action.[11][2][8]

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 Best Prediction Markets UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
