Market context

On 15 June at 7:45PM ET, the San Diego Padres travel to face the St. Louis Cardinals in a regular-season MLB matchup. The market resolves to the Padres if they win, to the Cardinals if they win, and splits 50-50 only if the game is postponed indefinitely or cancelled without a make-up fixture. Settlement occurs by 22 June 2026, with official MLB statistics as the authoritative source.

A 0% implied probability for either side is unusual and typically signals a data feed issue, missing odds calculation, or a market that hasn't yet attracted liquidity. Historical comparison: markets on regular-season MLB games between evenly matched teams usually settle between 45–55% for the favourite, reflecting both team strength and home-field advantage. The Cardinals hold a slight edge in recent head-to-head records, though the Padres' roster composition has shifted materially since 2024. For programmatic traders, this suggests the market may be mispriced or inactive—checking volume and bid-ask spreads before committing capital is essential.

Key catalysts include starting pitcher announcements (typically confirmed 48 hours before first pitch), injury reports released during the settlement window, and weather conditions in St. Louis that could affect play. Recent roster moves or trades affecting either team's lineup strength should be monitored via MLB.com and team official channels. Conditional order logic might gate entry until pitcher confirmation or until the market shows non-zero probability on both sides, signalling genuine trading activity rather than a stale feed.

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.
