How Do Cardinals vs. Cubs Odds Compare on Polymarket and Kalshi?
Both exchanges price their MLB odds for this game in cents, so a yes share costs roughly what the market thinks the outcome is worth. Sportsbooks list Chicago near -183, or 64.7%, but that carries the house margin. Strip it out and the fair price is closer to 62%.
| Cardinals vs. Cubs market | Polymarket | Kalshi | Book equivalent |
|---|---|---|---|
| Cubs yes | 62¢ | 64¢ | -183 |
| Cardinals yes | 38¢ | 37¢ | +150 |
| Over 8 runs | 49¢ | 51¢ | Even money |
Prices move constantly, so check both order books before you commit. Two cents on a $20 bonus is small money, but shopping the exchange against the book is where the edge lives.
What Is the Cardinals vs. Cubs Pick?
Chicago sits 71-50, second in the NL Central, holds a Wild Card spot, and is 35-24 at Wrigley. St. Louis arrives 61-60, third in the division and one game over .500.
Clay Holmes starts for the Cubs with a 2.86 ERA against Matthew Liberatore's 5.15, and wind projects to blow in from right at roughly 8 mph, the most run-suppressing forecast on today's slate.
The pick I suggest yo make after redeeming Polymarket MLB referral code ACTION is the Cubs YES at 62¢ or better, with a secondary lean to the under 8. One projection model disagrees and forecasts 8.9 runs, so size that second position accordingly.
