Terms:

• New customers only. Earn a cash bonus (the “Base Bonus”) when you deposit and maintain funds with partner banks on the Raisin platform. Customers will receive a Base Bonus of $50 for depositing between $10,000 and $24,999; $125 for depositing between $25,000 and $49,999; $250 for depositing between $50,000 and $99,999; $500 for depositing between $100,000 and $199,999; and $1,000 for depositing $200,000 or more.
• Customers may earn an additional bonus by setting up a recurring deposit within 14 days of their initial deposit (the “Recurring Deposit Bonus”). To qualify, the recurring deposit must be established within 14 days of the initial deposit date and it must execute at least two (2) times within 90-days of the initial deposit. Recurring Deposit Bonus eligibility is determined by your Base Bonus tier:
  • Customers depositing between $10,000–$24,999 with aggregate recurring deposits of $100 or greater receive a $10 bonus
  • Customers depositing between $25,000–$49,999 with aggregate recurring deposits of $250 or greater receive a $25 bonus
  • Customers depositing between $50,000–$99,999 with aggregate recurring deposits of $500 or greater receive a $50 bonus
  • Customers depositing between $100,000–$199,999 with aggregate recurring deposits of $1,000 or greater receive a $100 bonus
  • Customers depositing between $200,000+ with aggregate recurring deposits of $2,000 or greater receive a $200 bonus
• Customers are eligible to earn the Recurring Deposit Bonus associated with their Base Bonus tier or any lower Recurring Deposit Bonus tier. For example, a customer with an initial deposit of $200,000 (qualifying for the highest Base Bonus tier) whose aggregate recurring deposits total $500, is eligible for the lower tier and will receive the $50 Recurring Deposit Bonus. However, setting up a recurring deposit greater than your Base Bonus tier’s required threshold will not qualify you for a higher Recurring Deposit Bonus.
• The Recurring Deposit Bonus is paid in addition to the Base Bonus. To qualify for the Base Bonus and Recurring Deposit Bonus, your first deposit must be initiated between June 1, 2026, and June 30, 2026, by 11:59 PM ET, and the promo code SUMMER26 must be entered at the time of sign-up. Only funds deposited within 14 days of the initial deposit date and maintained with partner banks on the Raisin platform for 90 days will be eligible for the Base Bonus. Bonus cash will be credited directly to your Cash Account within 30 days of meeting all qualifying terms. 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.
