How the Kalshi Promo Code SIBONUS Works for Monday's MLB and WNBA Games

The Kalshi promo code SIBONUS delivers a straightforward welcome offer: deposit at least $20, trade at least $20 on any available market, and you'll receive a $20 bonus. You must be 18 or older and a new Kalshi user to qualify. The code is required during registration, so enter SIBONUS when you create your account.

Here are the key terms you need to know:

Minimum deposit of $20 is required to participate
You must complete at least $20 in trades within seven days of registering
The bonus applies regardless of whether your trades on Monday's Cardinals-Reds doubleheader, Padres-Mets, Braves-Twins, or Wings-Valkyries game win or lose
Your bonus credit must be used within seven days of being granted
Account registration and identity verification are required

Let's say you trade $20 on the Dodgers-Rockies matchup at Coors Field. If your prediction wins, you keep your winnings plus the $20 bonus. If your trade loses, you still receive the $20 bonus to use on other markets. The bonus applies to any outcome, making it a straightforward way to explore Kalshi's prediction markets without worrying about your initial trade results.
