Market context

The Detroit Tigers face the Chicago White Sox on 31 May at 2:10 PM ET in an American League Central divisional matchup. Both clubs enter the contest mid-season with established records and roster configurations that will determine the outcome. The settlement window extends to 7 June, providing a buffer for any postponements or scheduling complications that might delay the final result.

A 0% implied probability for either side suggests the market has encountered liquidity constraints or reflects an extreme confidence in one outcome that hasn't yet materialised in trading volume. Historical precedent shows that early-season divisional games between these franchises typically settle within a 45–55% range, with home-field advantage and recent form driving modest shifts. The White Sox have struggled more consistently in recent seasons, whilst the Tigers have shown competitive improvement, yet single-game outcomes remain inherently volatile. Traders evaluating this market programmatically should flag the probability as potentially mispriced if it remains at zero, as even heavily favoured teams rarely command absolute certainty in baseball.

Key variables for conditional order logic include starting pitcher announcements (typically confirmed 24 hours before first pitch), weather conditions at Guaranteed Rate Field, and any late roster moves affecting batting lineups. Recent injury reports or bullpen availability changes can shift expected value substantially. Traders using copy-trading or bot automation should monitor MLB official sources and team injury reports through 30 May, as these catalysts directly influence win probability models used by sophisticated market participants.

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.
