Market context

The Chicago White Sox will travel to San Francisco to face the Giants on 22 May at 10:15 PM ET in a regular-season Major League Baseball matchup. The market resolves to the White Sox if they win, to the Giants if San Francisco prevails, and 50-50 in the event of postponement without rescheduling or a tied result. Settlement occurs by 30 May 2026.

The 100% implied probability reflects either illiquidity in the market's early phase or a technical artefact; comparable MLB head-to-head markets typically show meaningful probability separation based on recent form, injury status, and pitching matchups. Historical precedent from similar sports markets suggests that as liquidity deepens, probabilities converge toward fair value around 48–52% for evenly matched opponents. The White Sox and Giants' relative strength in late May 2026 will determine whether this probability persists or recalibrates significantly.

Traders should monitor roster announcements, particularly starting pitcher confirmation and any late-notice injuries to key position players, in the week preceding the fixture. Weather conditions at Oracle Park—notably wind direction and temperature—materially affect outcomes in San Francisco's ballpark. Under German GlüStV regulations, this market may face restrictions if offered to German residents without proper licensing, whilst US CFTC oversight applies to derivatives-like structures. The no-KYC threshold of $1,500 USD per trade means traders can access this specific market without identity verification up to that stake level, provided the platform holds appropriate regulatory standing in their jurisdiction.

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.
