Market context

The St. Louis Cardinals face the Milwaukee Brewers on 25 May at 2:10 PM ET in a regular-season Major League Baseball fixture. The current crowd-implied probability of 33% for a Cardinals victory reflects moderate confidence in the Brewers' chances, though both clubs remain competitive within the National League Central division. Settlement occurs on 1 June 2026 at 18:10 UTC, allowing a week buffer beyond the scheduled game date for official statistics confirmation and any weather-related postponements.

Historical matchup data between these franchises shows relatively balanced outcomes over recent seasons, with neither team commanding a decisive edge in head-to-head records. The Cardinals have maintained inconsistent form in May fixtures across multiple years, whilst the Brewers have demonstrated stronger early-season performance. Current divisional standings and recent win-loss streaks as of late May will materially influence market pricing; traders should monitor roster announcements, particularly regarding starting pitcher assignments and injury status updates, which typically emerge 24–48 hours before game time. Weather forecasts for the game location become increasingly relevant as the scheduled date approaches, given that rain or severe conditions could trigger postponement under MLB protocols.

From a regulatory standpoint, this market's accessibility varies by jurisdiction. Under German GlüStV provisions, traders in that territory face stricter KYC requirements regardless of stake size. US CFTC reach extends to certain prediction market operators, though sports-outcome markets occupy a distinct regulatory space from derivatives. The "no-KYC up to $1,500" threshold commonly cited by platforms typically applies to aggregate account activity rather than individual market positions, meaning traders should verify their platform's specific compliance framework before participation.

Methodology

We track St. Louis Cardinals vs. Milwaukee Brewers on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
