Chicago White Sox vs. San Francisco Giants

Platform comparison

Active sub-markets

Market context

The Chicago White Sox will face the San Francisco Giants on 22 May at 10:15 PM ET in an MLB regular-season fixture. The market currently reflects a 100% implied probability for the White Sox, which typically signals either extremely lopsided betting action or a data-feed anomaly; MLB games rarely settle with such certainty given inherent match variance and late-inning reversals. Settlement occurs by 30 May 2026, allowing a one-week window for postponement resolution under the stated terms.

Historical precedent shows that 100% probabilities in MLB markets often precede sharp reversals once injury reports, bullpen availability, or weather updates surface within 48 hours of first pitch. The Giants' recent form and pitching matchup details—particularly starter assignment and San Francisco's home-field advantage if applicable—typically drive material repricing. Traders should monitor official MLB injury bulletins and weather forecasts for the venue, as these catalysts have historically shifted comparable games by 15–25 percentage points in the final trading window.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV provisions, sports prediction markets require specific licensing; UK-based traders face FCA oversight, whilst US participants encounter CFTC reach on certain derivatives. Platforms offering no-KYC access up to $1,500 USD typically operate under exemptions for low-value wagers, though this threshold applies per transaction rather than cumulative exposure. Traders should verify their local regulatory status before entry, as settlement certainty does not exempt compliance obligations.

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.
