Detroit Tigers vs. Chicago White Sox

Market context

The Detroit Tigers face the Chicago White Sox on 31 May at 2:10 PM ET in a regular-season Major League Baseball matchup. The market currently shows zero probability assigned to either outcome, reflecting either minimal trading activity or a technical reset ahead of the settlement window closing on 7 June. Resolution hinges on official MLB final statistics; postponement extends the market's life, whilst cancellation without a make-up game or a tie triggers a 50–50 split.

Regulatory frameworks governing this market's accessibility vary by jurisdiction. Under German GlüStV provisions, sports prediction markets face stricter licensing requirements than financial derivatives, affecting EU trader participation. The US CFTC maintains broad reach over prediction contracts settled in dollars, though the agency has historically exercised discretion regarding low-value sports wagers. Most platforms operating under no-KYC thresholds up to $1,500 USD per transaction treat baseball markets as lower-friction entry points; this particular contract's modest notional value likely qualifies, meaning traders can establish positions without full identity verification provided cumulative exposure remains beneath that ceiling.

Traders should monitor roster announcements and injury reports from both clubs in the week preceding the fixture. Recent form matters: the White Sox's 2024 season performance and the Tigers' divisional standing will influence sharp money positioning. Weather conditions at the venue and any late bullpen adjustments announced on game day can shift implied probabilities sharply in the final hours before first pitch. Official lineups typically confirm 24 hours prior to start time.

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.

How does resolution work?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
