Market context

The St. Louis Cardinals travel to Milwaukee on 25 May for a 2:10 PM ET matchup against the Brewers in what shapes as a mid-season divisional contest. The current 35% implied probability for a Cardinals victory reflects the Brewers' standing as slight favourites in this National League Central fixture. Settlement occurs on 1 June at 18:10 UTC, allowing for weather postponements or scheduling adjustments common to late May baseball.

Historical matchup data and recent form provide the foundation for reading this probability. The Cardinals and Brewers have maintained competitive parity over the past three seasons, with neither club establishing decisive dominance in head-to-head records. Win-loss records as of late May typically show both clubs within striking distance of .500, making divisional games particularly sensitive to roster health, recent momentum, and starting pitcher matchups. The 35% Cardinals probability suggests market participants view Milwaukee's pitching depth or home-field advantage as material factors.

Traders should monitor lineup announcements and injury reports through 25 May, particularly regarding starting pitchers and key position players. Recent transactions—trades, call-ups, or disabled-list moves—can shift expected run production substantially. Weather forecasts for Milwaukee on game day merit attention, as cool temperatures and wind direction affect ball carry and scoring patterns. Deposit flows into major prediction platforms typically accelerate ahead of weekend sports events; withdrawal rails including SEPA transfers, Klarna settlements, and USDC on-chain redemptions remain active throughout the settlement window, supporting liquidity for position adjustments as new information emerges.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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.

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
