Walmart vs. Swipe Fees: The Legal Battle That Could Change How You Pay

Emily Jones · 2026-09-22

Imagine you're running a retail business. Every time a customer swipes a credit card, a chunk of that sale goes to the card networks—Visa, Mastercard—and the banks. These are called swipe fees, or interchange fees. For years, merchants have argued these fees are too high and lack transparency. In 2005, a massive class-action lawsuit was filed, and after years of litigation, a settlement was reached in 2013. But now, Walmart and other retailers are saying that settlement is unconstitutional. Why? Because they're being forced to stay in a class they never wanted to be part of. They argue this violates their due process rights under the Fifth Amendment. Let's break down what this means for businesses and consumers. ### The Swipe Fee Settlement: A Quick Refresher Back in 2005, a group of merchants sued Visa, Mastercard, and several major banks, alleging that they conspired to fix swipe fees. The case dragged on for years. Finally, in 2013, a settlement was approved: the card networks agreed to pay $5.7 billion and to temporarily reduce swipe fees by about 0.1% for eight months. Merchants who accepted the settlement gave up their right to sue over these fees in the future. But not all merchants were happy. Many, including Walmart, had already opted out of the settlement. They wanted to pursue their own lawsuits. However, the settlement's terms forced them back into the class, meaning they couldn't sue separately. That's the crux of the current legal challenge. ### Why Walmart and Others Call It Unconstitutional The merchants argue that being forced into a settlement class they explicitly opted out of violates their due process rights. Under the Constitution, you can't be bound by a judgment if you weren't adequately represented or if you didn't have a chance to opt out. But here, the settlement was structured so that even those who opted out were still bound by the release of claims. That's a problem. As one legal expert put it, "It's like being forced to join a club you never wanted to join, and then being told you can't leave." The retailers are asking the courts to declare this aspect of the settlement unconstitutional. If they succeed, it could reopen the door for individual lawsuits against the card networks, potentially leading to billions more in damages. ### What This Means for Your Business If you're a business owner, you might be wondering how this affects you. First, swipe fees are a significant cost. In the U.S., merchants pay over $100 billion annually in swipe fees. That's money that could be used to lower prices, hire more staff, or invest in your business. Any change that reduces these fees could be a big win. Second, this legal battle could set a precedent for how class-action settlements are handled. If merchants can opt out and still sue, it gives them more leverage. But it also means more uncertainty for the card networks, which might pass on costs to consumers. So, it's a double-edged sword. ### The Road Ahead The case is currently in the appeals process. The Supreme Court may eventually weigh in. In the meantime, merchants and card networks are watching closely. Some experts believe that if the settlement is overturned, it could lead to a new wave of lawsuits and potentially a renegotiation of swipe fees. Others think it might push Congress to act, passing legislation to regulate interchange fees. Either way, the outcome will shape the future of electronic payments in the U.S. > "The current system is broken. Merchants are tired of being squeezed by hidden fees.
