Market context

The Oakland Athletics travel to Houston on 7 June for an afternoon fixture against the Astros, with settlement determined by official MLB final statistics. The current crowd-implied probability of 0% for an Athletics victory reflects the substantial gap in recent performance between these division rivals. Houston has maintained a winning record throughout the 2026 season, whilst Oakland has struggled consistently, creating a significant disparity in expected outcomes that the market has priced to near-certainty.

Historical matchups between these teams show the Astros have dominated recent head-to-head play, winning the majority of encounters over the past two seasons. The Athletics' inability to compete effectively in divisional play has been a defining feature of their campaign, with particularly weak performances against Houston's established rotation. This historical pattern, combined with current form differentials, explains why traders have assigned minimal probability to an Oakland upset.

Key variables for market movement centre on lineup availability and pitching assignments. Any late injury announcements to Houston's starting rotation or batting order could shift the probability materially, though such developments remain speculative at this stage. The Astros' consistency in run production and defensive execution has been reliable throughout June, whilst Oakland's offensive output has remained inconsistent. Weather conditions at Minute Maid Park on game day warrant monitoring, as afternoon games in Houston occasionally see weather delays that could affect settlement timing before the 14 June deadline.

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.
