Market context

The Miami Marlins travel to Pittsburgh on 13 June for a regular-season matchup against the Pirates, with first pitch at 4:05 PM ET. The current 45% implied probability for a Marlins victory reflects modest confidence in Miami's chances, positioning this as a near-toss-up from the market's perspective. Settlement occurs seven days after the scheduled game, allowing time for any postponements to be resolved before the 20 June deadline.

Historical matchup data and recent form provide the baseline for evaluating this probability. The Marlins and Pirates have played 162 times since 2012, with Miami holding a slight edge in head-to-head records during competitive seasons. However, 2024 and early 2025 performance diverges significantly: Pittsburgh has shown stronger consistency in division play, whilst Miami's roster volatility and injury patterns have created unpredictability. Comparable games between these teams when Miami sits below .500 typically settle around 40–48% implied probability for the visiting team, suggesting current odds align with historical precedent.

Traders monitoring this market should track starting pitcher announcements, which typically arrive 48–72 hours before game time and materially shift probabilities. Recent roster moves, particularly any last-minute transactions affecting either bullpen depth or offensive lineup composition, warrant programmatic alerts. Weather conditions at PNC Park—particularly wind direction affecting fly-ball outcomes—and any injury updates to key position players should feed into conditional order logic. The seven-day settlement window creates arbitrage opportunities if live-game data becomes available before the formal resolution window closes.

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.
