New York Mets vs. Philadelphia Phillies

Active sub-markets

Market context

The New York Mets vs Philadelphia Phillies market is trading at **46% YES** on Polymarket, so the contract is slightly cheaper than a coin flip even though the game itself is a tight division matchup. On Polymarket, that price is paid in USDC on Polygon, with the outcome ultimately settling through the platform’s conditional token structure rather than a straight sportsbook payout.

For traders reading the number in context, 46% implies the market is giving the Mets a modest underdog chance relative to a near-even game. That sits awkwardly against the live betting screen, where published moneylines are split across sources: one listing has the Mets around **-152** and the Phillies **+126**, while another has the Phillies marginally favoured at about **-121** and the Mets at **+110**. That kind of disagreement is normal in MLB pricing, especially when line movement and pitching information are still filtering through, but it also means the Polymarket contract is reflecting a blended view rather than a single sportsbook.

The main catalysts to watch are the official line-up cards, any late pitcher change, and whether the game starts on time at Citizens Bank Park. The market description says postponements keep the contract open until the game is completed, while a cancellation or tie resolves 50-50, so weather or schedule disruption matters as much as the baseball itself. Reuters-style event coverage has repeatedly shown that late pitching scratches and weather delays are the two fastest ways to move baseball prices near first pitch, and that is the same type of dependency that can reprice a Polygon-based prediction market in minutes.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
