Chicago White Sox vs. Detroit Tigers

Market context

Polymarket is pricing the White Sox side at **6% YES**, which leaves Detroit heavily favoured in the contract on USDC-settled, Polygon-based conditional tokens. The underlying game is Chicago at Detroit, with first pitch listed for 1:40 p.m. ET, and the market will resolve on the official result unless the game is postponed, cancelled, or finishes tied, in which case the contract’s 50-50 fallback applies.

That price is materially below the broader betting market’s read. Recent previews have Detroit around -120 to -160 on the moneyline, while Chicago has been quoted from about +100 to +132, implying a White Sox win probability well above 6% after vig; one market snapshot also showed near-even public betting splits despite those odds, which matters less than the price itself but does explain why the contract is not completely dead. Comparable cases on Polymarket usually trade at a few per cent when the away side is a clear underdog, because that still leaves room for a single bullpen collapse, late lineup change, or weather-related restart to swing the settle outcome.

For a trader, the main catalysts are the confirmed line-up cards, starting pitching, and any postponement risk close to first pitch, because those are the factors most likely to move the on-chain price before the 17:40 UTC settlement window closes. The game is also dependency-sensitive: if it is suspended or rescheduled, the market stays open until completion, so the real risk is not just which club wins, but whether the scheduled contest is finished cleanly under MLB’s official final statistics.

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.
