Terms:
- New customers to the Raisin platform only. New customers are eligible to earn a cash bonus each quarter for all of 2026 when they deposit and maintain funds with partner banks and credit unions on the Raisin platform subject to the following terms. To qualify, sign up and initiate your first deposit between December 1, 2025, and December 31, 2025 using promo code GIFT during signup. Qualified new customers will then receive a quarterly bonus based on their Eligible Deposit balance maintained on the Raisin platform for each quarter. Quarterly bonus tiers for Eligible Deposit balances are: $20 for balances between $10,000 and $24,999, $50 for balances between $25,000 and $49,999, $100 for balances between $50,000 and $99,999, $200 for balances between $100,000 and $249,999, and $500 for balances of $250,000 or more. “Eligible Deposits” are defined as both funds on deposit and deposits initiated on the Raisin platform by the 14th day of a calendar quarter (the “Qualification Date”). To qualify for a bonus tier, your Eligible Deposit balance must remain above the minimum for a bonus tier from the Qualification Date until the end of that quarter. If your Eligible Deposit balance declines at any time during a quarter after the Qualification Date, you will be placed in the bonus tier corresponding to your lowest Eligible Deposit balance for that quarter even if you subsequently deposit additional funds in that same quarter (though such funds will count as Eligible Deposits for the following quarter). Customers may increase their Eligible Deposit balance and corresponding potential bonus tier by adding funds prior to the quarterly Qualification date (i.e., the first 14 days of the quarter). Bonus payouts for each quarter will be credited directly to your Cash Account within 30 days of that quarter’s end. This offer is available to new customers only and may not be combined with any other bonus offers. Raisin may modify or end this offer at any time and may withhold or revoke bonuses in cases of fraud, abuse, or violation of these terms or Raisin’s Terms of Service.
