Market context

On 22 June at 7:07 PM ET, the Houston Astros and Toronto Blue Jays will face off in a Major League Baseball game at Rogers Centre in Toronto. In prediction markets, a YES share pays out if the selected outcome occurs—here, if the Astros win—while a NO share pays out if it does not. The current crowd-implied probability of 0% for YES suggests the market believes an Astros victory is virtually impossible, a stark contrast to their historical competitiveness.

Historically, MLB games with 0% implied probability for one side have rarely materialised, often reflecting data errors or extreme sentiment rather than reality. For instance, in the 22 June matchup, the Blue Jays won 4–2, securing their first series win and returning to 500 form at 39–39, while the Astros lost despite Jeremy Peña exiting with a hamstring cramp [2][5]. Comparable cases show that even heavily favoured teams can falter due to injuries or off-days, framing today’s 0% as potentially overconfident rather than definitive.

Traders should monitor injury updates, pitching lineups, and weather conditions before the game, as these are primary catalysts for outcome shifts. The Astros’ recent loss involved Peña’s exit, and any recurrence of such injuries could further depress their win probability [5]. Additionally, check MLB.TV and ESPN for confirmed starting pitchers and late roster changes, as these directly influence game dynamics [1]. With the settlement window ending 23 June 2026, timely information remains critical for accurate positioning.

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.
