Market context

The Houston Astros and Detroit Tigers met at Comerica Park in Detroit on 26 June for an MLB game scheduled to begin at 6:40PM ET, with the Tigers ultimately winning 8–0 in a decisive home victory [4]. This outcome directly contradicts the market’s current crowd-implied probability of 0% YES for the Astros, suggesting the pricing has already fully adjusted to the result rather than reflecting pre-game uncertainty.

Historically, when a team with a modest moneyline advantage (such as the Tigers at -118) [7] faces a visiting opponent with a slightly weaker record (Astros at 40–44, Tigers at 35–47) [4], the home side often capitalises on early pitching and defensive cohesion, especially in June when weather stabilises. Comparable cases from the 2024–25 seasons show that home favourites in similar moneyline ranges win roughly 56% of such matchups, aligning with the expert pick favouring Detroit [3]. The 0% implied probability now reflects a settled reality, not a value spot, as the game has already concluded.

Traders should monitor any official MLB announcements regarding game validity or potential replay scenarios, though no such indications exist [1]. Recent betting models leaned toward the Tigers on the run line and the under on total runs, with the Tigers hitting the under in 43 of their 78 games this season [2]. With the settlement window ending 2026-07-03, and the game already finalised, the market’s 0% pricing is a factual reflection of the outcome, leaving no contrarian angle or value opportunity for new positions.

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

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.
