Market context

Polymarket is pricing Chicago White Sox vs Detroit Tigers at **81% YES**, well above the 68% pre-game win chance shown by several sportsbook and model feeds for Detroit, which implies the contract is currently trading with a strong lean towards Chicago under Polymarket’s on-chain market structure. On Polymarket, traders are swapping **USDC** against **conditional tokens** on Polygon, so the contract price reflects the market’s live view of who will win outright, not run line or total runs, and settlement will follow the official final result from the game’s governing statistical source.

That 81% level is high relative to comparable pre-match views because public odds screens have generally made Detroit the favourite: FanDuel’s research page put the Tigers at **68.3%** to win, with Detroit around **-250** on the moneyline, while other preview pages also showed Detroit as a shorter-priced favourite. Action Network’s matchup page also listed Detroit as the moneyline favourite and showed stronger recent spread results for the White Sox despite a worse overall record, which is the kind of split that can keep prediction-market pricing away from a simple translation of sportsbook implied odds. In practice, Polymarket traders often price in roster news, lineup confirmation, or a sharper read on the game state than a static pre-game number.

The main catalysts still worth watching are the confirmed starting pitchers, last-minute lineup changes, and any weather or postponement risk, because a delay keeps the market open until the game is completed, while a cancellation or tie would settle 50-50 under the contract rules. ESPN and other pre-game feeds are tracking the matchup in real time, and once line-ups are posted the price can move quickly if a key hitter is scratched or a starter is replaced.

Methodology

We track Chicago White Sox vs. Detroit Tigers 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.
