Pronóstico: Washington Nationals vs. Colorado Rockies

Platform comparison

Market context

The Washington Nationals have already secured a 7–3 victory over the Colorado Rockies at Coors Field on Monday night, 20 July 2026, with Andrés Chaparro, Jacob Young and CJ Abrams each hitting home runs to lead the win[1][4]. This outcome means the prediction market titled “Washington Nationals vs. Colorado Rockies” is effectively settled, as the game has been completed and the Nationals are the confirmed winners.

On Polymarket, this contract trades at 100% YES for the Nationals, reflecting the on-chain certainty that the resolution source—the official MLB final statistics—will name them the victor[1]. Historical cases of MLB games resolving after completion show that once a result is official, conditional tokens on Polygon settle instantly in USDC, with no further price movement unless a rare cancellation or tie occurs, which the rules explicitly exclude here[2][4]. The 50–50 tie clause only applies if the game is cancelled entirely or ends without a winner, neither of which has happened.

Traders should monitor the official MLB final stats page for any post-game adjustments, though such changes are uncommon once the result is published[1]. With the settlement window ending on 28 July 2026, the market will resolve automatically once the data is confirmed, and no further catalysts—such as pitcher announcements or schedule changes—will alter the outcome[2][3]. The game was part of a three-game series, but only this single match determines the contract’s resolution.
