Cincinnati Reds vs. St. Louis Cardinals

Platform comparison

Market context

Polymarket’s contract is trading at a **42% implied YES** price for the Cincinnati Reds, so the market is currently leaning towards St. Louis rather than a Reds win. On Polymarket, that price reflects a position settled in **USDC** on **Polygon**, with the outcome determined by the game’s official final result; if the game is postponed, the market stays open until completion, while a cancelled game or tie resolves 50-50.

Recent head-to-head results do not point strongly in either direction, which helps explain a mid-range price rather than a clear favourite. St. Louis took the first two games of a June series against Cincinnati, winning **10-3** and **6-5**, before the Reds responded later in the month by splitting a doubleheader and taking one game **7-6 in 11 innings**[4][5][1]. That mix of one-run margins and late scoring suggests this matchup has been competitive rather than one-sided, so a low-40s Reds price is consistent with a market that sees meaningful upside but no dominant edge.

For traders, the main catalysts are the confirmed line-ups, starting pitchers and any pre-game weather or delay updates, because those can affect both the probability of the game being played as scheduled and the expected scoring environment. The settlement window runs well past first pitch, so the practical risk is not the on-chain mechanics but the baseball logistics: a postponement keeps the contract alive, while only a completed official game settles it. Recent game recaps also show both clubs can generate late swings and bullpen volatility, which matters for in-play reassessment if the market remains open after a delay[2][4].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
