Each offer below includes its terms and a step-by-step guide to claiming it.


No. 1: Kalshi

*Certain limitations apply. The offer is available to new users only, subject to the terms and conditions at http://kalshi.com/tc/55. 18+ only. Restrictions and eligibility requirements apply. Event contract trading involves significant risk and is not appropriate for everyone. Please carefully consider if it is appropriate for you in light of your personal financial circumstances. Kalshi products are not available in all jurisdictions. See kalshi.com/regulatory for more information.

Kalshi Promo Code: Trade $25, Get $60

Enter the Kalshi promo code MAX60 during registration to claim the Trade $25, Get $60 offer for eligible new customers. Kalshi lets you trade contracts on sporting events, politics, breaking news, economics and pop culture.

Key terms and conditions:

  • The offer is available in all states except Nevada and Washington.
  • You must be physically present in an eligible location.
  • New customers can use either the code MAX60 or an eligible referral link, but not both.
  • The offer is limited to one per Kalshi account.
  • You must provide a government-issued ID or passport, along with a selfie holding that ID.
  • Make an initial deposit of at least $10 and transact at least $25 on Kalshi's Predictions product.

  • Bonus credit cannot initially be withdrawn, must be used on Kalshi's Predictions product and expires seven days after it is granted.

How to claim:

  1. Sign up and verify: Select "Sign Up" and enter the code MAX60 during registration. Provide your date of birth, phone number, location, Social Security number and a photo ID with a selfie.
  2. Deposit: Click "Deposit Cash" in your Kalshi wallet and choose a payment method. You must deposit at least $10.
  3. Trade: Browse the available markets and transact at least $25 on Kalshi's Predictions product. A high-volume market with clear rules and near-term settlement is a good fit.
