A Capital One Walmart credit card sign is seen at a store in Mountain View, California, United States on Tuesday, November 19, 2019.

Walmart's majority-owned fintech startup OnePay said Monday it was launching a pair of credit cards with a bank partner for customers of the world's biggest retailer.

OnePay is partnering with Synchrony, a major behind-the-scenes player in retail cards, which will issue the cards and handle underwriting decisions starting in the fall, the companies said.

OnePay, which was created by Walmart in 2021 with venture firm Ribbit Capital, will handle the customer experience for the card program through its mobile app.

Walmart had leaned on Capital One as the exclusive provider of its credit cards since 2018, but sued the bank in 2023 so that it could exit the relationship years ahead of schedule. At the time, Capital One accused Walmart of seeking to end its partnership so that it could move transactions to OnePay.

The Walmart card program had 10 million customers and roughly $8.5 billion in loans outstanding last year, when the partnership with Capital One ended, according to Fitch Ratings.

For Walmart and its fintech firm, the arrangement shows that, in seeking to quickly scale up in financial services, OnePay is opting to partner with established players rather than going it alone.

In March, OnePay announced that it was tapping Swedish fintech firm Klarna to handle buy now, pay later loans at the retailer, even after testing its own installment loan program.
