Market context

On 9 June, the Atlanta Braves will travel to face the Chicago White Sox in a regular-season Major League Baseball fixture. In prediction-market terms, a YES share represents a Braves victory, whilst a NO share represents a White Sox win. The current crowd-implied probability of 91% YES reflects strong consensus that Atlanta will prevail. When you purchase a YES share at that price, you're essentially betting that the Braves' superior roster strength and recent form will materialise in this single game; conversely, a NO share at 9% reflects the perceived likelihood of a White Sox upset.

The Braves have consistently ranked among baseball's stronger franchises over the past three seasons, whilst the White Sox have struggled with roster construction and competitive depth. Historical matchups between these teams, combined with the Braves' track record in June fixtures, provide context for why traders have priced this outcome so heavily in Atlanta's favour. However, individual games remain inherently volatile; pitching matchups, injury status, and weather conditions can shift outcomes substantially even when one team enters as a heavy favourite.

Traders monitoring this market should track roster updates through early June, particularly any late-breaking injuries to key players or unexpected lineup changes. Pitching assignments—announced typically 24 to 48 hours before game time—carry material weight in baseball prediction markets. Weather forecasts for the Chicago area on 9 June may also influence play, as wind direction and temperature affect ball carry distance. The settlement window extends to 16 June, allowing for postponements without market closure, though cancellations without rescheduling would trigger a 50-50 split 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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
