Market context

On 7 June, the San Francisco Giants travel to Chicago to face the Cubs in a regular-season Major League Baseball fixture. In prediction markets, a YES share represents a bet on the Giants winning; a NO share bets on a Cubs victory. The current crowd-implied probability of 46% for a Giants win reflects moderate confidence in Chicago, though the market remains relatively balanced given the inherent uncertainty of a single game outcome.

Historical matchups between these franchises show competitive balance over recent seasons, with neither team establishing decisive dominance in head-to-head play. The Cubs' recent performance trajectory and roster composition relative to the Giants' current form will anchor how traders assess the underlying probability. Both teams' win-loss records at the time of the fixture, injury status of key players, and their performance in comparable late-spring matchups provide empirical anchors for evaluating whether 46% fairly prices the Giants' chances.

Traders monitoring this market should track roster announcements in the days preceding the game, particularly any late injuries to starting pitchers or offensive linchpins. Weather conditions at Wrigley Field on 7 June—wind direction and temperature affect ball carry distance—represent a material variable affecting run-scoring likelihood. Recent form data released through early June games will refine probability estimates; a team entering the fixture on a winning streak typically sees its implied probability shift upwards. The settlement window closes on 15 June, allowing time for any postponement or rescheduling before final resolution.

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.
