New York Mets vs. Philadelphia Phillies

Platform comparison

Active sub-markets

Market context

The New York Mets are trading at a **55% implied probability** to win this game, so the market is leaning slightly to the Mets rather than treating this as a true coin flip. In handicapper terms, that usually means the consensus view is a modest edge to New York, while any Phillies case has to come from price rather than popularity.

That sort of number fits a spot where the favourite is credible but not dominant. The Mets are sitting **34-41** and the Phillies **40-35**, with Philadelphia the stronger team on the season, yet the market still has New York favoured in this matchup[5][3]. That creates the classic contrarian tension: if the Phillies are the better side by record, a 55% Mets price can look a touch rich unless there is a clear pitching or line-up edge behind it. The same game has also been shaded low in scoring, with a total around **7.5**, which tends to support a tighter, lower-variance contest rather than a runaway favourite[2][4].

For traders, the main catalysts are the confirmed line-ups, any late pitching change, and whether the price shifts after team news is finalised before first pitch. The game is scheduled for **7:15 PM EDT** at Citizens Bank Park, and the market remains live if postponed until it is completed; only a cancellation or tie triggers a 50-50 settlement[3][5]. That means the practical value question is whether the Mets’ slight edge is already fully priced in, or whether late lineup confirmation creates a better entry on Philadelphia as the underdog side.

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

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.
