Detroit Tigers vs. Chicago White Sox

Market context

The Detroit Tigers face the Chicago White Sox on 31 May at 2:10PM ET in an AL Central divisional matchup. Polymarket currently prices this contract at 0% YES, indicating traders assess negligible probability of a Tigers victory. This extreme pricing reflects either exceptional confidence in White Sox superiority or minimal liquidity depth in the conditional token pair (USDC-denominated) on Polygon, where even modest YES positions would move the price substantially upward from zero.

Historical context suggests such floor-level probabilities warrant scrutiny. In MLB regular-season games between comparable teams, Polymarket contracts rarely settle below 5% for either side unless one team faces catastrophic roster depletion or the matchup involves a pronounced talent gap. The Tigers and White Sox, both mid-table AL Central sides, typically generate more balanced implied odds. The 0% reading may reflect a data lag, thin order books on the YES side, or a recent roster development that hasn't yet propagated across all prediction platforms.

Traders should monitor starting pitcher assignments before the 31 May fixture. Recent injury reports from both organisations, available through MLB's official transactions feed and team announcements, directly influence perceived win probability. Additionally, the settlement window extends to 7 June at 18:10 UTC, providing buffer time for postponements—relevant given late-May weather patterns in the Midwest. Any shift in pitching matchups or unexpected roster moves could trigger significant repricing of this contract's conditional tokens.

Methodology

We track Detroit Tigers vs. Chicago White Sox on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
