Platform comparison

Active sub-markets

Market context

The Atlanta Braves will face the Boston Red Sox on 27 May at 6:45 PM ET in a regular-season Major League Baseball fixture. The market currently reflects near-parity at 49% implied probability for a Braves victory, suggesting traders perceive marginal advantage to the Red Sox. Settlement occurs on 3 June 2026, allowing a week-long window for postponements or make-up games; cancellation without rescheduling would trigger a 50–50 split resolution.

Historically, home-field advantage in MLB regular-season games correlates with roughly 54% win probability for the hosting team. The Braves' recent performance trajectory and Red Sox roster composition will anchor trader positioning. Comparable markets on this fixture across other platforms have typically reflected 48–52% ranges for the favoured side, suggesting current pricing aligns with consensus expectations rather than outlier sentiment. Injury reports and bullpen availability—particularly for teams' closer rotations—have historically shifted single-game probabilities by 2–4 percentage points in comparable matchups.

Traders should monitor roster announcements through 26 May, including confirmed starting pitchers and any late-notice injuries to key position players. Weather conditions at the venue on game day may influence run-scoring expectations. From a regulatory standpoint, this market operates under German GlüStV provisions if accessed from EU jurisdictions, whilst US CFTC oversight applies to participants in American territories. The no-KYC threshold of $1,500 USD per trader means positions below that exposure level avoid identity verification requirements on compliant platforms, though aggregate exposure across multiple markets may trigger verification 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.
