New users can claim a $35 bonus when they use the Kalshi promo code SI35 during registration and complete $25 in trades. As of Tuesday, September 1, this prediction market promos offer gives you extra capital to trade on marquee matchups like LSU versus Clemson or Oregon versus Boise State. The code is required to claim this welcome offer.

How the Kalshi Promo Code Works for Week 1 College Football

The Kalshi promo code SI35 delivers straightforward terms designed to get you trading immediately on college football outcomes. You must be at least 18 years old and a new Kalshi user to qualify for this welcome offer. The code is required at registration, and you'll need to complete identity verification before you can fund your account and begin trading.

Here's what you need to know about claiming this offer:

Deposit a minimum of $10 to your Kalshi account
Complete $25 in trades on any available markets, including college football games
Finish your $25 in trades within seven days of registration
Receive your $35 bonus credit regardless of whether your trades win or lose
Use your bonus funds within seven days before they expire

Let's say you deposit $35 and immediately trade $25 on LSU to beat Clemson at 7:30 PM ET Saturday night. Whether LSU wins or loses that matchup, you'll still receive your $35 bonus once the trade settles. If you want to trade another $5 on Boise State versus Oregon at 3:30 PM ET that same afternoon, you'll meet your $25 trading requirement and unlock your bonus. Your bonus funds then give you additional capital to explore other prediction market opportunities beyond college football.
