Walmart Inc. has filed a lawsuit against credit card partner Capital One, accusing them of failing to meet the customer service standards outlined in their contract. The lawsuit asks the New York federal court to find that Walmart is allowed to terminate their agreement with Capital One. This legal action comes after Walmart switched their primary credit card partner from Synchrony Financial to Capital One back in 2018. Capital One began issuing Walmart cards as part of the deal in August 2019. It was expected that this partnership would negatively impact Synchrony Financial's store credit card business, with Walmart representing almost 20% of their business, leaving nearly $10 billion in balances of Walmart cards issued by Synchrony Financial. As of now, the reason behind Walmart's lawsuit remains unclear. Meanwhile, Capital One's stock price ranged between $94.44 and $95.66 on April 8th, 2023, with a volume of 2,045,893 shares traded throughout the day.
