New York Mets vs. Cleveland Guardians

Platform comparison

Market context

The game is a straight moneyline call on whether New York or Cleveland wins, and the market’s 48% YES price implies a near coin-flip with a slight lean against the Mets. That is broadly consistent with the recent betting board, where sportsbook and model prices have oscillated around pick’em to modest Guardians edges, and the latest published probabilities have generally sat in the low-50s for Cleveland rather than showing a strong directional view.[2][10][12][13]

For context, the most recent meeting between these clubs ended Guardians 6, Mets 2 on 4 August, and ESPN’s game page recorded Cleveland as the winner in that contest.[8] Comparable markets have therefore been sensitive to small lineup and pitching changes rather than a large structural gap; when the spread and total are tight, the outright side often moves with late information, and programmatic traders usually key off the freshest moneyline rather than the run line or total as the cleaner input for a binary settlement.[2][7][12]

The main catalysts are the confirmed starting pitchers, any late scratches, and whether the scheduled first pitch remains intact, because postponement keeps the market open until a completed game is played, while a cancellation or tie resolves 50-50 under the contract terms. Current market pages show the game lined at roughly 7.5 runs and a live moneyline near pick’em, so any official lineup card release, weather delay, or last-minute rotation change can shift the implied win rate materially before the 17:10 UTC settlement window closes.[10][11][13]

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 Kalshi Fees, 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.
