Cincinnati Reds vs. St. Louis Cardinals

Active sub-markets

Market context

The Cincinnati Reds travel to St. Louis on 7 June for a regular-season Major League Baseball fixture against the Cardinals, with first pitch scheduled for 2:15 PM Eastern Time. The market resolves to the Reds if they win; to the Cardinals if St. Louis prevails. Should the game be postponed, the market remains open until completion. Cancellation without a rescheduled make-up game, or a tied result, triggers a 50–50 split resolution. The settlement window closes on 14 June at 18:15 UTC, providing a one-week buffer beyond the scheduled fixture date.

The 68% implied probability favouring Cincinnati reflects their recent form relative to St. Louis within the National League Central division context. Historical matchups between these rivals show competitive balance, though seasonal strength and roster composition shift annually. Traders should monitor pre-game roster announcements, particularly regarding starting pitcher assignment and injury status for key position players, as these factors materially influence win probability in single-game markets. Weather conditions at Busch Stadium—temperature, wind direction, and precipitation risk—can affect play and should be tracked through National Weather Service updates in the days preceding the fixture.

From a regulatory standpoint, this market operates under differing frameworks depending on trader jurisdiction. UK-based participants fall under the Gambling Commission's purview; EU traders may encounter German GlüStV restrictions on unlicensed betting platforms. US CFTC authority extends to certain prediction market operators, though sports-outcome markets occupy a distinct regulatory space. Many platforms offer no-KYC access up to $1,500 notional exposure per market, meaning traders below that threshold avoid identity verification requirements—a material accessibility feature for casual participants, though settlement and withdrawal procedures remain subject to platform-specific compliance protocols.

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.
