How the Kalshi Promo Code Works for Lions vs. Bengals

The Kalshi promo code SIBONUS delivers a welcome bonus when you sign up and meet the trading requirements. You must be at least 18 years old and new to Kalshi to qualify for this offer.

The bonus applies regardless of your trade outcomes

For Lions vs. Bengals, you could place your qualifying trades on game outcomes, player performance metrics, or any other available markets on the platform. If you trade $25 on whether Detroit's backup quarterback completes a certain number of passes and that trade settles, you'll unlock your bonus.

The key is completing $25 in settled trades within the seven-day window. After that, your bonus funds arrive in your account and you can deploy them across Kalshi's full marketplace of real-world event contracts.
