Market context

The Arizona Diamondbacks and St. Louis Cardinals faced off in their Major League Baseball clash on Wednesday, 24 June, with the game concluding under clear conditions at Busch Stadium. The Diamondbacks, sitting at 40-39 and third in the NL West, played away with a 16-22 record, while the Cardinals held a 42-35 overall mark and a strong 22-18 home advantage in the NL Central. The final result confirmed the Diamondbacks as the victors, aligning with the market’s 100% YES probability for an Arizona resolution, and the game was not postponed or cancelled, ensuring immediate settlement.

Historically, similar mid-season matchups between teams with comparable win-loss splits and home-away disparities have resolved decisively when one side holds a clear pitching advantage, as seen in the Cardinals’ -120 favourite line and the Diamondbacks’ -102 underdog status. In past cases where the home team’s record exceeded 20-18 and the away team hovered near 40-39, the outcome typically favoured the side with superior recent form, mirroring this game’s decisive finish without ties or cancellations, which would have triggered a 50-50 split.

Traders should monitor immediate post-game announcements regarding player injuries or roster changes, particularly following Matthew Liberatore’s recent struggles, which were cited as his worst start of the year prior to the game [5]. Additionally, watch for any official MLB confirmations on game statistics, as the primary resolution source relies on the event’s final official data [3]. No further catalysts are expected given the game’s completion, but any discrepancies in scoring reports could delay settlement, though none have arisen as of early Thursday.

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.
