Market context

On 14 June 2026, the Miami Marlins will host the Pittsburgh Pirates in a regular-season Major League Baseball fixture at loanDepot park in Miami. A YES share in this market represents a bet on the Marlins winning; a NO share represents a bet on the Pirates. The current crowd-implied probability of 63% YES suggests traders view the Marlins as moderate favourites, though the outcome remains genuinely uncertain. The settlement window extends to 21 June, allowing time for any postponements to be resolved before final determination.

The Marlins and Pirates occupy different competitive positions within the National League Central. Miami has historically underperformed relative to payroll, whilst Pittsburgh has cycled through rebuilding phases that have occasionally produced competitive windows. Head-to-head records between these clubs show relatively balanced results over recent seasons, with home-field advantage typically conferring a modest edge. The 63% probability reflects neither a dominant favourite nor a toss-up, suggesting the market is pricing in the Marlins' home advantage and recent form without overweighting either factor.

Traders should monitor roster updates and injury reports in the days preceding the match, particularly regarding starting pitchers and key position players. Weather conditions at game time—Miami's June climate frequently produces afternoon thunderstorms—could affect play quality and game duration. Any late-season trades or roster moves announced by either franchise between now and 14 June may shift the probability, as would unexpected managerial decisions or public statements about player availability. The settlement mechanism accounts for postponements, ensuring the market remains open if weather forces a reschedule.

Methodology

We track Miami Marlins vs. Pittsburgh Pirates on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
