Cincinnati Reds vs. Pittsburgh Pirates

Platform comparison

Market context

The Cincinnati Reds and Pittsburgh Pirates played their MLB matchup on June 28, 2026, at 1:35PM ET, with the Pirates securing a decisive 9-4 victory. On Polymarket today, this contract resolves to "Pittsburgh Pirates" with a crowd-implied probability of 0% for the Reds, reflecting the on-chain certainty that the game has already concluded. USDC balances on the Polygon network now lock in conditional tokens that will settle to the Pirates, as the official final statistics from MLB confirm the outcome without ambiguity.

Historically, similar MLB markets where a game has finished but the market remains open for settlement show near-zero probability for the losing side once results are verified. In the June 28 series finale, Ryan O'Hearn hit two home runs as the Pirates topped the Reds, with the over/under of 9 runs seeing 13 scored, confirming the over bet won [2]. Past cases where teams scored significantly above the total, such as this 13-run game, consistently drive prediction markets to 0% for the underperforming team once the official score is recognised.

Traders should monitor the settlement window ending 2026-07-05T17:35:00Z, though no further catalysts exist since the game is complete. The primary resolution source is the official final statistics, which already confirm the Pirates' 9-4 win and the Reds' loss [4]. Recent highlights show the Pirates outpowering the Reds to salvage the series, with no postponement or cancellation affecting the result [3]. With the outcome fixed, conditional tokens will settle automatically, requiring no further announcements or schedule dependencies.
