St. Louis Cardinals vs. New York Mets

Platform comparison

Active sub-markets

Market context

The St. Louis Cardinals face the New York Mets in a regular-season MLB matchup on 11 June at 1:10PM ET, with settlement occurring by 18 June. This is a straightforward moneyline resolution: Cardinals victory triggers YES settlement, Mets victory triggers NO settlement, with postponement extending the market window and cancellation or tie resulting in 50-50 split.

The 0% crowd probability reflects either extreme recency bias or incomplete market data at the time of snapshot. Historical comparison: similar pre-game markets typically show 40–60 range distributions for evenly matched teams, with favourites rarely exceeding 65% unless facing depleted rosters or significant injury absences. The Cardinals and Mets occupy mid-table positions in their respective divisions as of early June, suggesting neither enters with overwhelming structural advantage. Checking recent head-to-head records and run differential across the preceding month provides calibration; teams with consistent run-differential edges of +15 or greater tend to sustain probability floors around 55–58%.

Traders implementing conditional orders should monitor three variables: starting pitcher announcements (typically confirmed 24–48 hours pre-game), weather conditions affecting play at Citi Field or Busch Stadium, and roster updates regarding key position players or bullpen availability. The MLB injury report updates daily; significant absences—particularly among starting lineups or primary relief arms—shift moneyline probabilities by 3–5 percentage points. Programmatic approaches benefit from pulling official MLB schedule data and cross-referencing weather APIs against game time, as postponement risk directly affects settlement timing rather than outcome probability.

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

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.

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
