Market context

The Detroit Tigers travel to Chicago to face the White Sox on 31 May at 2:10 PM ET in an AL Central divisional matchup. The 0% implied probability reflects either technical market conditions or a significant structural imbalance in the underlying matchup that traders have already priced in decisively.

Historical context matters here: the White Sox have endured one of the worst seasons in franchise history, whilst the Tigers have stabilised their roster around young talent and mid-season acquisitions. When one team enters a game with a losing record approaching .300 and the other sits comfortably above .500, the probability gap widens substantially. The White Sox's pitching depth has been depleted by injuries and trades, and their offensive production ranks among the lowest in baseball. The Tigers, by contrast, have benefited from consistent contributions from their core and improved bullpen management under their coaching staff. Past matchups between teams in such disparate form typically see the stronger side favoured at 75–85% or higher.

Traders should monitor roster updates through 30 May, particularly any late-inning injury reports affecting either team's starting pitcher or key position players. Chicago's recent transactions—including mid-season departures of veteran players—signal a rebuild trajectory that may affect lineup construction. Detroit's recent form, documented by beat reporters covering the team, will clarify whether their early-season momentum has sustained. Weather conditions at Guaranteed Rate Field and any bullpen availability changes announced on game day could shift expectations marginally, though the structural gap between these clubs appears substantial enough to withstand minor variables.

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.
