Market context

The Houston Astros defeated the Detroit Tigers 2–1 in their MLB game on 25 June 2026 at Comerica Park, with Tatsuya Imai striking out 10 batters and Taylor Trammell scoring the decisive home run. This outcome confirms the 100% YES crowd-implied probability for the Astros winning, as the game has already concluded and the official final statistics are recorded.

Historically, MLB markets showing 100% probability before a game’s completion have resolved correctly when the event was not postponed or cancelled, as seen in prior Astros–Tigers matchups where the under dominated with a 2–1 scoreline in three of their season games [3]. Comparable cases from 2024 and 2025 show that when a team’s win probability reaches full certainty pre-settlement, it reflects either a completed game or an insurmountable pre-match advantage, neither of which applies here given the game’s finality.

Traders should monitor any official MLB announcements regarding game cancellations or tie resolutions, though none are expected post-finality. Recent coverage from ESPN confirms the 2–1 result and Imai’s performance, eliminating uncertainty [1]. For this market’s traction, funding flows via Klarna, SEPA, and USDC on-ramps directly influence book depth, as deposit friction and withdrawal rails determine how quickly capital enters the prediction pool to lock in odds before settlement.

Methodology

We track Houston Astros vs. Detroit Tigers 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

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.
