Pittsburgh Pirates vs. St. Louis Cardinals

Platform comparison

Active sub-markets

Market context

The Pirates and Cardinals meet again in St. Louis after Pittsburgh was shut out 7-0 on Wednesday, a result that followed St. Louis’s 10-5 win in the series opener the night before. That split matters for pricing because the market is not asking who has the better season profile, but who is more likely to take the next nine innings. Recent head-to-head form still tilts towards St. Louis: the Cardinals have won four of the last five against Pittsburgh, which helps explain why a 28% implied probability on the Pirates looks like a clear underdog spot rather than a coin-flip range.

For traders running this like a live tool, the main inputs are starting pitchers, line-up confirmation, and whether either club rests regulars in a day game after a night game. Programmatically, the cleanest approach is to track official line-ups once posted, then compare any late scratches against expected batting order strength and bullpen usage from the previous two games. Wednesday’s result also matters operationally: Pittsburgh’s relievers were used to protect the shutout, so a model should discount availability if there is overlap in high-leverage arms. The recent scorelines, from ESPN and MLB.com’s game and scoreboard pages, give the most immediate context; anything that moves the opening line will usually be driven by confirmed starters or late roster news rather than the raw series score alone.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), 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.

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.
