The Kalshi promo code SI35 unlocks $35 in bonus trading credit, which is 40% more than most competing Kalshi promo codes. You'll need to complete $25 in qualifying trades to claim your bonus, and you can use those trades on the Broncos-Chiefs game or any other event available on the platform. As of Monday, September 14, this prediction market promos offer represents one of the best welcome bonuses available.

How the Kalshi Promo Code Works for the Broncos vs Chiefs

The Kalshi promo code SI35 requires a minimum deposit of $10 and completion of $25 in trades within seven days of registration. Once you settle $25 worth of trades, your $35 bonus credit appears in your account and remains valid for seven days. Whether your trades on the Broncos-Chiefs game win or lose, you still receive the full $35 bonus, making this offer valuable regardless of your prediction accuracy.

Here are the key terms you should know:

You must be 18 or older and a new Kalshi user to qualify
Enter code SI35 during registration to activate the offer
Complete identity verification with a government-issued ID
Deposit at least $10 to your account
Settle $25 in trades within seven days to unlock the bonus
Your $35 bonus credit expires seven days after being credited
The bonus applies to any market, including the Broncos-Chiefs prediction contracts

Imagine trading on whether the Chiefs cover the spread against Denver. If you place a $25 trade on that outcome and it settles, your $35 bonus immediately credits to your account, giving you additional capital to explore other markets like politics, entertainment, or future NFL games. The bonus works the same way whether your Broncos-Chiefs trade wins or loses.
