Pronóstico: Washington Nationals vs. Colorado Rockies

Platform comparison

Market context

The Washington Nationals have already secured a 7-3 victory over the Colorado Rockies in the July 20 MLB game at Coors Field, with Andrés Chaparro, Jacob Young and CJ Abrams each hitting home runs to lead the win[1][2][5]. Because the game has been completed and the Nationals won, the prediction market resolving to “Washington Nationals” is effectively settled at 100% YES, matching the crowd-implied probability.

Historically, when a game finishes before a prediction market’s settlement window closes, the outcome is determined by the official final result rather than future uncertainty; this mirrors past MLB markets where completed games resolved instantly once the final score was confirmed by the league[1][3]. In comparable cases, a 100% YES probability for the winning team post-game reflects the absence of any remaining risk, as no postponement or cancellation can alter an already-finished result.

Traders should watch for any official MLB confirmation that the game is final and not subject to replay or protest, though such scenarios are rare in regular-season MLB[1]. With the Nationals’ 51-50 overall record and 31-19 road form contrasting the Rockies’ 3-7 last-10 slump and extensive injury list—including starters Jose Quintana and Jaden Hill on the IL—the pre-game line already favoured Washington, and the result now locks in the outcome[3]. No further announcements or schedule changes can affect this market, as the event is complete.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
