Market context

The Arizona Diamondbacks travel to Miami for a regular-season matchup against the Marlins on 10 June at 6:40 PM ET. The settlement window extends to 17 June, providing a five-day buffer for postponements or rescheduling. Current crowd-implied probability sits at 100% YES, indicating near-total consensus that the game will be completed and resolved to either team, with negligible perceived risk of cancellation or tie outcomes.

A 100% probability on game completion reflects historical MLB scheduling reliability. Since 2020, regular-season games between established franchises have been cancelled outright in fewer than 0.5% of cases, with most disruptions resulting in rescheduled make-up games rather than voids. The Diamondbacks and Marlins have played 180+ games against each other since 2000 without a tie, and weather-related postponements in early June at Miami typically result in same-season reschedules within the settlement window. This market structure essentially prices the game as certain to resolve to a winner.

For programmatic traders, the key dependency is weather tracking for the Miami area in the 48 hours preceding the match. Tropical storm systems or extreme heat advisories could trigger postponement, though the settlement window's length makes rescheduling probable. Injury announcements affecting either team's starting pitcher would shift win-probability models but wouldn't affect game completion. Monitoring official MLB communications and venue-specific weather alerts through 10 June remains the primary variable; the current 100% probability leaves minimal edge unless unforeseen cancellation risk emerges.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
