Pittsburgh Pirates vs. St. Louis Cardinals

Platform comparison

Active sub-markets

Market context

The Pittsburgh Pirates and St. Louis Cardinals are scheduled to meet in MLB action, and the market will settle on whichever club is credited with the official win. The crowd price at 0% YES is best read as a stale or miskeyed signal rather than a live view of the matchup, because baseball results resolve strictly on the final score and make-up arrangements if the game is postponed. Comparable Cardinals-Pirates meetings have recently leaned St. Louis’ way: ESPN reported a 10-5 Cardinals win on 30 April 2026, part of a four-game sweep in Pittsburgh, and StatMuse shows the Cardinals have gone 5-0 in their last five against the Pirates. That sort of short-run head-to-head form is not decisive, but it is the cleanest recent frame for interpreting a low or uninformative probability.

For traders, the relevant catalysts are the same ones that move any MLB moneyline-equivalent market: confirmed starters, late line-up scratches, bullpen availability, and whether weather or scheduling creates a delay or postponement that pushes settlement past the original date. MLB.com’s Pirates scoreboard and game pages are the most direct live reference for status changes, while the final official statistics will govern settlement if the game is completed. On access, this type of market is generally visible to users without full identity checks up to the platform’s no-KYC threshold of $1,500, although that does not alter how the event resolves. In a regulatory context, German GlüStV rules can restrict access for German residents, and US CFTC reach is relevant where the platform or user falls within US derivatives oversight, but those are venue and eligibility issues rather than factors in the result itself.

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.
