Market context

The Toronto Blue Jays face the Baltimore Orioles on 31 May at 12:15 PM ET in a regular-season Major League Baseball fixture. The 3% crowd-implied probability assigned to a Blue Jays victory reflects market confidence in the Orioles' superiority in this matchup, though single-game baseball outcomes carry inherent volatility. Settlement occurs on 7 June at 16:15 UTC, with the official MLB final statistics serving as the authoritative resolution source. Should postponement occur, the market remains open until completion; cancellation without a rescheduled game or a tied result triggers a 50-50 split resolution.

Historical context for single-game baseball markets shows that crowd-implied probabilities below 5% typically reflect either substantial roster disadvantage, recent performance divergence, or pitching matchup asymmetry. The Orioles' 2024 campaign positioned them as a competitive AL East contender, whilst the Blue Jays faced mid-season roster questions. Comparable matchups in prior seasons demonstrate that crowd probability at this level rarely shifts materially absent late-breaking injury announcements or weather-related game-time complications.

Traders should monitor starting pitcher confirmation and any roster changes announced within 48 hours of game time, as these remain the primary catalysts for probability adjustment in single-game markets. Weather conditions at Rogers Centre in Toronto and any last-minute bullpen availability updates could influence in-game dynamics. The settlement window's extension to 7 June accommodates potential postponement scenarios common to late-May baseball scheduling, particularly given the Northeast's seasonal weather patterns.

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.
