Amazon's Business Credit Cards Left American Express for U.S. Bank on August 14, 2026 — New Mastercards, the 5% Cap Rises From $120,000 to $150,000, Amex Points Had to Be Redeemed by August 12, and Every Recurring Payment on the Old Card Number Breaks
The Amazon Business Card and Amazon Business Prime Card co-brand relationship with American Express ended on August 14, 2026. Existing accounts converted to replacement Prime Business Card and Amazon Business Card products issued by U.S. Bank on the Mastercard network, with physical cards mailed in late July and early August. The core Amazon earn rate survived the move and the annual cap on it actually went up, but the account numbers changed, the redemption window on the Amex side closed on August 12, and transferred rewards were not accessible again until August 20 — a six-day gap in the middle of Q4 inventory buying season. Sellers who used the card to buy inventory, supplies or AWS capacity and had autopay or recurring vendor charges attached to the old number had to re-enter details before the cutover.
Real-World Impact
At the 5% Prime Business rate, the cap increase moves the maximum annual reward on Amazon-covered sites from $6,000 (5% of $120,000) to $7,500 (5% of $150,000) — $1,500 more per year for a seller who runs at least $150,000 of sourcing spend through the card.
Key Points
- American Express's co-brand relationship with Amazon for the Amazon Business Card and Amazon Business Prime Card ended August 14, 2026. Accounts transferred to U.S. Bank and run on the Mastercard network instead of American Express
- Replacement cards were mailed in late July and early August 2026 and became active August 14. U.S. Bank told cardholders to contact it if a card had not arrived by August 10
- Prime Business Card earns 5% back at Amazon Business, Amazon.com, AWS, Whole Foods Market and on prepaid travel; the non-Prime Amazon Business Card earns 3% on the same covered sites and prepaid travel
- The annual cap on that top rate rose from $120,000 of net purchases under the Amex program to $150,000 under U.S. Bank. Spend above the cap earns 1%
- Both cards add a dynamic 2% back on the cardholder's top three eligible spending categories each billing cycle, capped at $150,000 spent per calendar year, plus 1% on all other Mastercard purchases
- New on the U.S. Bank cards: eligible Amazon purchases can be split into fixed monthly payments at 0% APR for up to 12 months. Taking the installment option means forgoing rewards on that transaction
- Points on the Amex side could be earned through August 13 and redeemed through August 12, 2026. Unredeemed points transferred one-to-one to the U.S. Bank account but were not redeemable again until August 20
- American Express online and app access to the account ended August 14. Automatic payments scheduled after August 16, 2026 were cancelled by American Express on transferred accounts, so autopay and any bill-pay entries keyed to the old account number had to be rebuilt at U.S. Bank
- Amex-network benefits do not automatically carry over — coverages tied to American Express, such as its return protection, are not part of the Mastercard product
- Amazon stopped accepting requests for additional employee cards on the Amex program from July 2, 2026
What You Should Do Now
- 1Confirm the replacement card arrived and is activated. If it never showed up, contact U.S. Bank directly — the Amex account is closed to new activity and cannot be used as a fallback
- 2Rebuild autopay at U.S. Bank. American Express cancelled automatic payments scheduled after August 16 on transferred accounts, and a missed statement here is a credit event, not just a late fee
- 3Update the card number everywhere it is stored on file — Amazon Business purchasing, AWS billing, prep centers, freight forwarders, software subscriptions and any supplier portal set up for recurring charges
- 4Check that unredeemed Amex points landed in the U.S. Bank account after August 20 and reconcile the balance against your final Amex statement
- 5If you are financing Q4 inventory, price the new 0% APR installment option against your existing credit line, and remember that taking installments forfeits the 5% or 3% back on that purchase — on Amazon-covered spend the rewards are often worth more than the float
- 6Do not assume purchase protections carried over. Re-read the U.S. Bank benefits guide before relying on any coverage you used to get through American Express
