Market context

The upcoming MLB clash between the Oakland Athletics and the San Francisco Giants, scheduled for 9:45pm ET on 24 June at Oracle Park, pits two teams in contrasting recent form. The 51% crowd-implied probability favouring the Athletics barely reflects their precarious position: they have lost three of their last five games, including a 3-1 defeat to the Giants on 23 June, and sit at 11-16 overall. Conversely, the Giants are 15-16, having won their last meeting, though they have also lost three of their previous five outings. Historically, such marginal probabilities in head-to-head MLB matchups often resolve to the home side when the away team carries significant injury baggage, as the Athletics do with Brent Rooker (10-day IL) and Zack Gelof (day-to-day) missing or limited, while the Giants are without Heliot Ramos and Harrison Bader.

Traders must monitor pre-game starting line-up confirmations and weather updates, as the Athletics’ projected batting order wOBA of .324 suggests a lineup considerably missing its usual firepower compared to their .338 season average[3]. The absence of Rooker, a key offensive driver, is critical, and any late confirmation of his replacement could shift the line significantly. Additionally, the Giants’ bullpen grades as the 6th-worst in the league, a vulnerability that could be exploited if the game extends beyond the starter’s pitch count, which projection systems limit Tyler Mahle to 78 pitches[3]. With the over/under set at 8.5 runs, defensive frailties—particularly the Athletics’ weakest infield defence—will be a decisive factor[3].

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.
