August 21, 2026 update: Rakuten has added the Chase Ink Business Cash to this promotion, offering the same $100 cash back or 10,000 Bilt points available with the Ink Business Unlimited. The Ink Business Cash also has the same elevated 100,000-point welcome offer and no annual fee.
Rakuten is offering a $100 bonus (or 10,000 Bilt points if you've selected Bilt as your earning preference) when applying for either the Chase Ink Business Unlimited or Chase Ink Business Cash as a new Chase for Business customer. Both Ink cards currently offer elevated 100,000-point welcome bonuses with no annual fee, making these especially appealing offers. Rakuten is also offering $25 cash back or 2,500 Bilt points on the Chase Freedom Unlimited, which stacks with that card's current welcome offer. If you're in two-player mode, however, the 40,000-point Ink referral bonus is generally the better option, provided the applicant is a brand new Chase for Business customer. If your Rakuten account is set to earn Amex Membership Rewards, you will not see these offers. Rakuten earnings must be set to cash back or Bilt points.
