NFL Week 1 kicks off with a loaded slate, and you can maximize your trading experience with a Kalshi promo code. As of Monday, September 7, new users can claim a $35 bonus when they trade at least $25 on the platform using code SI35. The Patriots-Seahawks matchup, the 49ers-Rams game in Melbourne, and the Broncos-Chiefs division showdown all present compelling trading opportunities. Explore prediction market promos to see what other platforms offer, but Kalshi's welcome bonus stands out for its simplicity and value.

How the Kalshi Promo Code SI35 Works for NFL Week 1 Trading

The Kalshi promo code SI35 delivers straightforward terms: deposit at least $10, complete $25 in trades within seven days, and receive a $35 bonus credited to your account. You must be 18 or older and a new Kalshi user to qualify. The bonus applies regardless of whether your trades win or lose, so you can trade on Patriots-Seahawks, 49ers-Rams, or any other Week 1 matchup without worrying about the outcome affecting your bonus eligibility.

Here are the key terms to keep in mind when claiming this offer:

  • You must enter code SI35 during registration to qualify
  • A minimum deposit of $10 is required to fund your account
  • You must settle at least $25 in trades within seven days of signing up
  • Your $35 bonus credit must be used within seven days of being granted
  • Identity verification through KYC is required before trading
  • The bonus applies to all available markets, including sports events like NFL Week 1

If you trade $25 on the Patriots-Seahawks matchup and it settles, your bonus posts immediately. You could then use those funds to trade on the 49ers-Rams game in Melbourne or the Broncos-Chiefs Monday night showdown. The bonus credit expires after seven days, so plan your trades accordingly to make the most of your welcome offer.

How to Claim Your Kalshi Welcome Bonus for NFL Week 1

Signing up and claiming your bonus takes just a few minutes. Follow these steps to start trading on NFL Week 1 events:

  1. Create your account: Visit Kalshi's sign-up page and enter your email, phone number, and residential address. Enter the promo code SI35 during registration to ensure your bonus qualifies.
  2. Complete identity verification: Submit a government-issued ID and a selfie to verify your identity. This Know Your Customer (KYC) process is standard for regulated prediction markets.
  3. Fund your account: Deposit at least $10 using a supported payment method like debit card or PayPal. You can deposit more to have additional trading capital beyond the $25 required for the bonus.
  4. Place your first trade: Trade at least $25 on any available market, including NFL Week 1 games like Patriots-Seahawks, 49ers-Rams, or Broncos-Chiefs. Once your trade settles, your $35 bonus credit appears in your account.
  5. Use your bonus: Apply your bonus funds to additional trades on any Kalshi market within seven days of receiving the credit.
