🏆 Who will win Reds vs. Cubs? Live MLB win probability

The Reds vs. Cubs game outcome market is giving Chicago a clear edge heading into Sunday night’s matchup at Wrigley Field. The prediction market has the Cubs at 59% to win, compared to 41% for the Reds, making Chicago the preferred side despite Cincinnati sending Chase Burns to the mound. Burns owns a strong 14-3 record with a 2.77 ERA, while Shota Imanaga will start for Chicago with an 8-9 record and 3.78 ERA. The 18-percentage-point gap suggests the market believes Chicago’s home-field advantage and overall season form outweigh the pitching matchup.

My prediction: Cubs (59%) win. The Cubs will win because their offense has been rolling, highlighted by a 17-5 blowout of the Reds on Saturday and a league-best .428 slugging percentage. With Chicago also holding a strong 39-28 home record, the combination of Wrigley Field and a powerful lineup gives the Cubs the edge despite Chase Burns’ excellent season.

💣 Who will hit a home run in Reds vs. Cubs?

The Reds vs. Cubs home run market features several intriguing options, with four hitters standing out in the prediction markets. Pete Crow-Armstrong leads the way at 24%, making him the highest-probability home run candidate after an incredible three-homer performance against Cincinnati on Saturday. Elly De La Cruz and Sal Stewart are both listed at 21%, while Alex Bregman sits at 15%. With all four hitters carrying legitimate power upside, the market is especially interesting at Wrigley Field. Crow-Armstrong’s recent production makes his 24% probability difficult to ignore.

My prediction: Alex Bregman (15%) to hit a home run. Alex Bregman is a strong home run candidate after going deep against the Reds on Saturday, giving him excellent recent momentum at the plate. With the prediction market giving him a 15% home run probability, Bregman offers intriguing value as a power play for the Cubs.

⚾ Will there be a run in the first inning of Reds vs. Cubs?

The Reds vs. Cubs NRFI/YRFI market is essentially a coin flip heading into Sunday night’s matchup, with prediction markets giving both outcomes a 50% probability. That split reflects an intriguing pitching matchup between Cincinnati’s Chase Burns and Chicago’s Shota Imanaga. Burns has posted a strong 2.77 ERA with 164 strikeouts this season, while Imanaga enters with a 3.78 ERA and 144 strikeouts. While a 50/50 market offers no clear probability edge, the combination of two quality starters makes the first inning particularly difficult to predict.

My prediction: No run in the first inning (50%). The NRFI is an appealing angle because both teams are facing quality starting pitchers in Chase Burns and Shota Imanaga. Burns owns a 2.77 ERA with 164 strikeouts, while Imanaga has a 3.78 ERA and a 2.48 ERA across five career starts against Cincinnati. With the prediction market sitting at a 50/50 split, there is no built-in edge, but the strength of both starters makes a scoreless opening frame worth targeting.
