Athletics vs. San Francisco Giants

Active sub-markets

Market context

The underlying real-world event is an MLB game between the Athletics and the San Francisco Giants, scheduled for 3:45 PM ET on 25 June at Oracle Park in San Francisco, where the market resolves to "Athletics" if they win and to "Giants" if they win, with a 60% crowd-implied probability favouring the Athletics[1][6].

Historical precedents in MLB prediction markets show that when a team like the Athletics faces a starter with a sub-1.30 ERA against them, such as Jeffrey Springs who holds a 1.23 ERA in three career outings versus the Giants, the implied probability often shifts sharply despite recent team form, as Springs' dominance in this specific matchup outweighs the Athletics' four recent losses[5][7]. This pattern mirrors cases where a single high-impact pitcher stabilises a team's odds, suggesting the current 60% figure may be a rational reflection of Springs' proven efficacy rather than an overreaction to the Athletics' broader slump.

Traders should monitor the official starting lineups released before 3:00 PM ET, as any change to Springs' status would drastically alter the probability, and watch for weather updates at Oracle Park, which can influence run totals and game outcomes[2][3]. Recent coverage notes that Springs is closing out the three-game set in San Francisco, making his availability the primary catalyst for this market's resolution[5]. The regulatory landscape includes German GlüStV implications for EU traders, US CFTC reach for American participants, and the "no-KYC up to $1,500" threshold, which allows immediate access to this market without identity verification for smaller stakes, enhancing liquidity for casual bettors.

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.
