Market context

The upcoming MLB fixture pits the Houston Astros against the Detroit Tigers at Comerica Park on 25 June, with the game scheduled for 6:40PM ET. This single contest forms the basis of a prediction market where a "YES" outcome resolves if the Astros secure the win. Current crowd-implied probability sits at 85% for the Astros, a figure that starkly contradicts traditional moneyline data which lists the Tigers as favourites at -114 and the Astros at -105, suggesting a significant divergence between public sentiment and professional betting models[2][3].

Historically, such a probability gap often mirrors scenarios where home-advantage metrics are overstated by retail bettors, yet professional run-line pricing indicates the Tigers hold a genuine pitching edge, priced at -1.5 for -190[1]. In comparable MLB cases, markets with 80%+ implied win probabilities for a team listed as an underdog on the moneyline frequently correct sharply once the game begins, as the initial pricing fails to account for the home team's recent back-to-back winning form and the specific pitching matchup favouring Detroit[1].

A power-user evaluating this tool programmatically must monitor the official starting pitcher announcement and the live run-line movement, as the 8.5 to 9.0 run total suggests a balanced offensive output that could invalidate the high Astros win probability if the Tigers score early[1][2]. Traders should watch for any late-injury news regarding the Tigers' rotation, as recent trends indicate Rotoworld Bet is leaning towards a Tigers moneyline play and an over on the total, which directly challenges the 85% crowd consensus[2]. The settlement window ending 2026-07-02 allows for a postponed game, but the immediate catalyst is the confirmed starting lineups and the live odds shift away from the Astros' inflated implied probability[1].

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.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
