Brewers vs. Cubs Game Details
Tuesday brings the second game of a four-game NL Central series at Wrigley Field.
| Matchup | First Pitch | TV | Venue |
|---|---|---|---|
| Brewers at Cubs | 7:40 p.m. ET | TBS | Wrigley Field |
Milwaukee entered the series at 85-52 with a sizable lead over Chicago in the NL Central, while the Cubs came in at 77-60 and still firmly positioned in the National League playoff race.
Tuesday's probable pitching matchup features two left-handers. Robert Gasser is scheduled for Milwaukee at 4-5 with a 4.59 ERA and 78 strikeouts, while Matthew Boyd goes for Chicago at 8-3 with a 3.99 ERA and 76 strikeouts. MLB also confirms the 7:40 p.m. ET start on TBS.
Brewers vs. Cubs: MLB Odds
Kalshi currently makes this game about as close to a coin flip as possible.
| Team | Kalshi Price | Implied Probability |
|---|---|---|
| Cubs | ~51¢ | 51% |
| Brewers | ~49¢ | 49% |
The live order book has Chicago around 51 cents and Milwaukee around 49 cents, although the exact buy price can vary depending on which orders are available when you open the market.
That is notable because the gap between these teams over the full season has been much wider than the gap in Tuesday's market.
Milwaukee entered this series with one of baseball's best records and a substantially better run differential. Chicago has remained dangerous at home and owns one of the National League's better offenses, but the market is effectively saying Wrigley Field and Boyd's starting-pitching advantage erase nearly everything separating the clubs.
Expert Pick: Brewers to Win at 49¢
At 49 cents, Milwaukee is the side I prefer. Boyd has the better season line between Tuesday's two starters, so this is not a case of Milwaukee holding every advantage. Gasser's 4.59 ERA gives Chicago a legitimate path to putting runs on the board early. Despite that I still like the brewers to win:
Pick: Brewers YES to win (49%)
Milwaukee entered the week eight games better than Chicago and has built that advantage with a more balanced roster. The Brewers entered the series having won five consecutive series, while Chicago had dropped three straight series despite remaining in good playoff position.
The Brewers also own the stronger pitching staff overall. That matters in a game where neither starter necessarily needs to work deep for his team to win. Chicago's lineup is the main reason I would keep the position small. The Cubs lead the National League in runs and OPS, and Boyd has been good enough this year to make 51 cents on the home side perfectly reasonable.
MLB Futures Worth Trading Now
Kalshi's broader baseball board gives you more than Tuesday's game if you do not want to put the entire $25 qualifying volume into one matchup.
The MLB futures market reflects just how much separation Milwaukee has created in the NL Central. Kalshi currently gives the Brewers roughly a 93% chance to win the division, while Chicago is down around 3%.
That division contract is probably too expensive to offer much upside at this point, but other Milwaukee futures remain more interesting.
| Brewers Future | Approx. Kalshi Price |
|---|---|
| Win NL Central | ~93¢ |
| Best MLB regular-season record | ~52¢ |
| Win National League | ~22¢ |
| Win World Series | ~13¢ |
Milwaukee is around 52 cents to finish with baseball's best regular-season record, while the Dodgers sit behind them on that board. The Brewers are also roughly 22 cents to win the National League and 13 cents to win the World Series. Traditional MLB odds tell a similar story. Milwaukee is now firmly among the league's top contenders, while Chicago remains in the postseason mix but has more work to do in the division.
Those prices make more sense for traders looking for upside than paying more than 90 cents on the division.
The gap between them also makes Tuesday's 49-51 game market interesting. Season-long prediction markets view Milwaukee as the substantially stronger club, yet one night at Wrigley Field is priced almost dead even.
