Pronóstico: Miami Marlins vs. St. Louis Cardinals

Platform comparison

Market context

The Miami Marlins and St. Louis Cardinals faced off in a Sunday afternoon MLB clash on 28 June 2026 at 2:15 PM ET, with the Cardinals securing a narrow 2–1 victory. On Polymarket today, this contract resolves to "St. Louis Cardinals" with certainty, meaning the "Miami Marlins" outcome sits at 0% implied probability, reflecting the on-chain settlement of the conditional token for the winning side.

Historically, similar MLB prediction markets where one team wins by a single run have resolved decisively once the final box score is confirmed, leaving no room for ambiguity or tie outcomes. In past seasons, when a team like the Cardinals covers the run line by winning two or more runs, the market clears instantly; here, the one-run margin still triggered full resolution because the game did not end in a tie or cancellation, aligning with the 50–50 clause only applying to those specific scenarios.

Traders should monitor the official MLB final statistics portal for any post-game corrections, though the ESPN box score already confirms the 2–1 result[4]. With the settlement window ending 5 July 2026, no further announcements are expected unless the game is officially postponed or cancelled, which it was not. The Palm Beach Post’s pre-game analysis noted the Cardinals’ -130 moneyline as the favoured outcome, which the result validated[2]. USDC balances on Polygon now reflect the resolved conditional tokens, closing the market with no open positions.
