Market context

The Arizona Diamondbacks travel to Miami for a regular-season matchup against the Marlins on 10 June at 6:40 PM ET, with settlement occurring after the final out on 17 June. The crowd-implied probability sits at 100% YES, indicating near-certain confidence in a decisive outcome rather than postponement or cancellation.

The 100% reading reflects the standard operational resilience of MLB scheduling in June, when weather disruptions and facility issues are comparatively rare. Historical data shows that regular-season games in this window settle to a winner roughly 99.5% of the time, with cancellations without make-up games occurring in fewer than 0.1% of cases. The Marlins' home venue in Miami has experienced weather-related delays, but outright cancellations are uncommon once a game reaches scheduled start time. This probability floor is consistent with how prediction markets price similar mid-season fixtures across the league.

Traders should monitor roster announcements in the days preceding the match, particularly injury updates to key players that might affect betting markets and public perception of team strength. Recent MLB scheduling has shown minimal disruption from weather in early June across Florida, though tropical systems remain a secondary consideration through the settlement window. The Diamondbacks' recent form and pitching rotation assignments will likely drive secondary market movements, though these factors do not materially affect the binary outcome of whether the game concludes with a winner rather than remaining unresolved.

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.
