It's still early in the week, making it the perfect time to claim the Kalshi promo code ACTION for a $25 bonus.
Just place a first-time trade of $25, and you'll get a $25 bonus to use on anything like Braves vs. Cubs (7:40 p.m. ET, TBS) in MLB, or NFL Week 2 and CFB Week 3 games starting on Thursday night.
Tonight's big game of the night goes down at Wrigley Field, in what could be a potential playoff preview next month. On the mound, Atlanta sends the southpaw Martin Perez (8-9, 3.08 ERA) to the mound while Chicago counters with Kevin Gausman (9-12, 4.60 ERA). This will be the second game of the three-game series, and you have to wonder how much hand either side wants to show right before October. Not to mention, Pete Crow-Armstrong (the likely NL MVP) continues his pursuit of a 40-40 season, sitting just a few stolen bases away from the accomplishment.
There is a huge week of storylines on the gridiron, and it all starts with the Lions vs. Bills game on Thursday. It will be the first time an NFL regular-season game takes place at the new Highmark Stadium, and both teams posted 30+ in their respective openers, setting the stage for a high-flying shootout. In college football, Lane Kiffin returns to Oxford for the LSU vs. Ole Miss game on Saturday night. Kiffin put himself in this situation, and we, the public, get to bask in the glory of watching it all unfold.
As a CFTC-regulated prediction market, Kalshi works differently from a traditional sportsbook. Traders take "Yes" or "No" positions at prices between $0.01 and $0.99, and each position ultimately settles at either $1 or nothing, depending on the outcome.

Kalshi Promo Code Eligibility and State Availability
Traders can sign up at 18 on Kalshi, below the 21-year-old minimum standard across most sportsbooks. CFTC oversight at the federal level gives the exchange a much wider reach than legal online sportsbooks have, with California, Texas, and Georgia all in play.

Kalshi MLB Odds: Braves vs. Cubs Preview & Prediction
Let's see how the Kalshi MLB odds stack up for tonight's Braves vs. Cubs matchup:
| Market | Braves | Cubs |
|---|---|---|
| Kalshi moneyline | 46¢ | 56¢ |
| Implied win probability | 46% | 54% |
Kalshi odds are subject to change before first pitch at 7:40 p.m. ET on Tuesday, September 15, 2026.
Martín Perez has been living dangerously all season. His 3.08 ERA looks the part, but his 4.24 FIP suggests the results have outrun the process, and a 1.77 strikeout-to-walk ratio is the tell: he isn't missing bats and barely surviving contact. That works against average offenses, but not against one of the best offenses in baseball. The Cubs lead the league with a .771 team OPS, and they get Perez at Wrigley, where a lineup that grinds at-bats and puts balls in play is going to find holes.
Kevin Gausman's 4.60 ERA undersells him in the opposite direction. His 3.77 FIP and 3.22 K/BB point to a pitcher whose peripherals have been considerably better than his ledger, and he draws a favorable matchup: Atlanta hits for power (188 HR) but ranks only 12th in team OPS at .721, a profile built on slugging the ball rather than getting on base. Power lineups that don't work counts are exactly what a splitter-heavy right-hander wants to see.
