Market context

Polymarket’s White Sox–Tigers contract is pricing **Chicago White Sox at 80% YES**, which is materially above the American odds being shown across the sports books and preview sites for the same game. ESPN’s game page lists Chicago as around a **-115** favourite, while Action Network and FOX Sports show a market closer to a coin-flip leaning Detroit on some boards, with Detroit around **-132 to -225** depending on the feed and format.[8][1][3] For a Polymarket user, that gap matters because the trade is settled in **USDC on Polygon** through conditional tokens, so the contract reflects the market’s view of the straight-up winner, not the run line or total.[8]

The current price is easiest to read against the teams’ season profiles. The White Sox are listed at **39-34** in multiple previews, while the Tigers are **30-44**, which is the kind of record split that can keep a favourite elevated even when the away team is at a respectable moneyline price.[1][2][6] Comparable MLB moneyline markets often move less on headline record and more on starting pitcher confirmation, bullpen availability, and late lineup changes; that is why a high YES price can survive even when some books still shade the underdog on the day.[1][8]

The main catalysts before settlement are the official **lineups, pitching announcement, and any weather-related delay or postponement** at Comerica Park, because the market stays open if the game is merely delayed and only resolves 50-50 if it is cancelled without a make-up or ends tied.[3] Traders should also watch for any schedule update that shifts the June 19 first pitch, since Polymarket resolution depends on the completed official result rather than live betting sentiment.[3][8]

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
