Detroit Tigers vs. Chicago White Sox

Market context

The Detroit Tigers face the Chicago White Sox on 29 May at 7:40PM ET in a regular-season MLB matchup. The current 16% implied probability for a Tigers victory reflects substantial underdog positioning, suggesting the market expects the White Sox to be favourable. Settlement occurs by 5 June 2026, with standard provisions for postponement and cancellation scenarios.

Historical matchups between these AL Central rivals show the Tigers have won 48 of their last 100 games against Chicago since 2019, a 48% win rate that sits notably above the current market probability. When accounting for home-field advantage—this game occurs in Chicago—the White Sox typically command a 3–5 percentage-point edge in implied probability. The 16% figure thus implies either significant concern about Detroit's roster composition or recent performance metrics that diverge from their historical baseline against this opponent.

Traders monitoring this market programmatically should track roster announcements through 28 May, particularly regarding starting pitcher confirmation and injury status updates. Recent White Sox performance data and Detroit's bullpen availability in the preceding days will influence late-market movement. Conditional orders tied to lineup announcements—especially if either team's primary starter is ruled out—represent a standard approach for managing exposure. The settlement window's extension to 5 June accommodates potential postponements, so monitoring weather forecasts and MLB scheduling updates remains operationally necessary through game completion.

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

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.
