Pronóstico: Chicago White Sox vs. Boston Red Sox

Platform comparison

Market context

Polymarket is pricing Chicago White Sox vs Boston Red Sox at **46% YES** on the Chicago side, with the contract settled in **USDC on Polygon** through conditional tokens rather than by sportsbook grading. That makes the 46% crowd price a direct read on where traders think the White Sox’s win probability sits, with the market staying open until the game is officially complete and reverting to a 50-50 outcome only if it is cancelled or ends in a tie under the stated rules.

Form and matchup data help explain why the contract is near coin-flip territory. ESPN lists Chicago at 47-42 and Boston at 40-48, but Boston has recently outperformed its record in the head-to-head, taking a 14-2 win on 5 August after earlier wins of 2-1 and 5-0 in the same stretch of meetings.[1][5][8][9] That recent series matters because traders often anchor to the latest run of results when pricing short-horizon MLB contracts, especially when one club has a stronger overall record but the other has the more efficient pitching line: ESPN’s snapshot shows Boston with a lower team ERA and WHIP, while Chicago has generated more offence and home runs.[1]

For traders, the key catalysts are late lineup news, starting pitcher confirmation, and any schedule movement that could trigger a postponement or a made-up completion under the market rules. The market’s settlement window extends beyond first pitch, so rain delays and rescheduling remain relevant even after the game starts; a clean finish is what matters for resolution.[1] Reuters reported Boston’s 14-2 win on 5 August as the opener of the series, which is the most recent result to feed momentum-based pricing, but the next meaningful move in the contract will come from pre-game roster and pitcher announcements rather than from long-term standings noise.[5]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
