Market context

The Houston Astros and Detroit Tigers face off in a Major League Baseball game at 1:10pm ET on 27 June, with the market currently pricing a 0% chance for the Astros to win. This near-zero probability mirrors historical patterns where underperforming road teams as underdogs face heavy favourites at home, particularly when the combined score line is set low. In the last five Astros road games as underdogs, the under has hit 4-1 times, while the Tigers have seen the under land 6-4 in their last ten home games as favourites, suggesting a tight, low-scoring contest that heavily favours the home side[6].

Traders should monitor player availability and late-inning pitching announcements, as injuries to key hitters like Riley Greene or Jeremy Pena could shift momentum instantly. Recent odds data from FanDuel shows Greene priced at +280 and Pena at +290, indicating their impact on the game’s outcome is already factored into the book depth[4]. The settlement window closes on 4 July 2026, and any postponement will keep the market open until completion, meaning funding flows via Klarna or USDC rails must remain liquid to support on-ramp friction during delays. Watch for official injury reports from MLB’s governing body, as these are the primary catalysts that will drive book depth and payment traction in the final hours[8].

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

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.
