Market context

The upcoming MLB game between the Arizona Diamondbacks and St. Louis Cardinals, scheduled for 7:45pm ET on 25 June, has been postponed, with the market remaining open until completion. This delay introduces on-ramp friction for traders seeking to deposit funds via Klarna or SEPA, as settlement uncertainty can temporarily stall withdrawal rails and reduce book depth. The current crowd-implied probability of 45% YES for Arizona reflects a cautious stance, mirroring historical cases where postponed mid-week MLB games saw initial odds swing 5–8% once lineups were confirmed and funding flows resumed.

Comparable postponed games in the 2024 and 2025 seasons showed that initial probabilities often overreacted to weather concerns before correcting once betting liquidity returned via USDC and other stablecoin rails. Traders should monitor the official MLB announcement on the rescheduled date, as dependencies like pitcher availability and stadium conditions will directly influence the final outcome. A recent update from ESPN confirms the postponement and notes both teams’ season records (Arizona 41–39), which may shape the revised odds once the game is played [5]. The catalyst for market traction will be the reactivation of deposit channels and the clarity of the new settlement window, which drives the depth of the book.

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.
