On Monday, April 27, 2026, the four largest retail trade groups in the country walked into Judge Brian Cogan's courtroom in the Eastern District of New York and asked him to reject a $200 billion settlement.

That is not a typo. The retailers, who would receive the money, are asking the court not to approve the deal.

What that tells you is that the headline number is doing a lot of hiding.

When the parties supposedly being made whole tell a federal judge they would rather take their chances at trial, the settlement is not a settlement. It is a structure preservation agreement.

What the Settlement Actually Does

The proposed deal lowers interchange fees, the swipe fees that merchants pay every time a customer pays with a Visa or Mastercard credit card, by 0.1 percentage points for five years. Interchange typically runs 2 to 2.5 percent of the transaction. The reduction works out to roughly $200 billion in merchant savings over eight years.

The settlement also lets merchants reject specific card categories, including commercial cards, premium consumer rewards cards, and standard consumer cards. Merchants would gain the ability to surcharge or offer discounts based on card type. The networks would walk away with the "honor all cards" rule narrowed.

That is the carrot. The stick, from the merchant point of view, is what the settlement does not do.

It does not change the structural rules that produce interchange in the first place. It does not give merchants leverage over future fee increases. It does not allow the case to proceed to trial, which retailers believe could deliver a worse outcome for the networks than the settlement does.

We have written about the underlying interchange dynamics before, including the grocery sector pay-by-bank push and the agentic commerce repricing pressure that may eventually do more damage to interchange than any antitrust judgment.

What the Retailers Said in Court

The objection is not that the settlement is too small. It is that it shifts the operational burden onto the people the antitrust action was meant to protect.

Mary Miller, representing the National Association of Convenience Stores and Circle K, made the argument plainly. "They're putting the onus on the merchants to correct" the anticompetitive structure, she said. "Merchants have a lot of work to do" under the proposed terms. "There's just something that doesn't make sense about requiring the merchants, who are arguably the ones being harmed by the anticompetitive scheme, having to do the work."

Jesse Panuccio, Walmart's attorney from Boies Schiller Flexner, was sharper. The settlement, he argued, asks Walmart to build its own rewards program to substitute for the value premium cards currently deliver. "By fiat, we have to come up with this new system that we don't have."

Debra Greenberger, representing the National Retail Federation and the Retail Industry Leaders Association, pointed at the structural tell. "If this was such a good deal, the parties should be happy to include an opt out. They didn't."

That last line is the crux. A settlement that is genuinely better than litigation should be able to withstand individual merchant choice. This one cannot.

What the Networks Said

Michael Shuster of Holwell, Shuster & Goldberg argued for Visa. He framed the abandonment of the "honor all cards" rule as "a big give" that merchants had spent two decades demanding.

That is technically accurate. The rule, which forces a merchant accepting a Visa card to accept every Visa-branded product including the most expensive premium rewards cards, has been a central merchant grievance since the 1990s. Removing it is genuinely meaningful.

The merchants' counter is operational. If a retailer like Walmart now has to decide which card categories to accept, build the technology to enforce that decision, train cashiers, communicate it to customers, and handle the disputes that follow, the cost of the "give" lands squarely on the people who already paid the inflated fees for two decades.

This is the recurring pattern in payments network reform. The networks pay headline dollars. The operating cost of implementing the change moves to merchants. The structural advantage stays with the networks.

The Judge Did Not Tip His Hand

Judge Brian Cogan posed questions throughout the hearing without revealing his position. To the merchants pushing for trial, he offered one comment that has been quoted widely since: "Be careful what you wish for."

He said he would issue a written decision "as soon as he could." The case is In re Payment Card Interchange Fee and Merchant Discount Antitrust Litigation. It has been pending in some form since 2005.

If Cogan approves the settlement, the formal antitrust route closes. Merchants will operate under the new surcharge and discount rules. The networks will pay out the $200 billion over eight years. The structural fight ends, on terms the largest merchants opposed.

If Cogan rejects it, the parties go back to negotiating, or the case proceeds toward trial. The networks face a real risk of a worse outcome. A jury that has heard two decades of evidence about coordinated fee-setting between Visa and Mastercard is not a friendly forum.

The merchants' calculation, stated openly in court, is that the trial risk is lower than the settlement cost. The networks' presence in the courtroom defending the deal suggests they agree.

The Pressure the Settlement Does Not Address

There are now three external pressures on interchange that no court order will fix.

State legislative action. Colorado's Senate just advanced SB26-134, which would prohibit interchange on the sales tax portion of debit and credit card transactions. Multiple states are watching. The structural fee model is now under direct legislative challenge in a way it was not five years ago.

Pay-by-bank rails. Real-time bank-to-bank rails like FedNow and the UK's Faster Payments cut the networks out of the transaction entirely. Grocery, the largest interchange category by absolute dollars, is moving fastest, as we covered in our grocery pay-by-bank piece.

Stablecoin settlement. Stablecoin transaction volume is now larger than Visa and Mastercard combined on settlement counts for some corridors. Most of that is wholesale, not retail point-of-sale, but the cost differential is the kind of fact that tends to migrate from one segment to the next.

A settlement that reduces interchange by 0.1 percentage points for five years does not change the trajectory of any of those pressures. It buys time. It does not buy structural protection.

What Comes Next

Watch three signals in the next 90 days.

Cogan's written decision. The hearing was Monday. A written ruling typically follows in weeks, not months. The longer it takes, the more likely the settlement is being modified rather than approved cleanly.

The Colorado bill. SB26-134 is the cleanest test of legislative appetite. If it passes the full state Senate, expect copycat bills in five to ten states within a year.

Network earnings calls. Visa and Mastercard report Q1 results in coming weeks. Watch for changes in interchange-related guidance, surcharge program commentary, and any acknowledgement of merchant-side defection to alternative rails. Their language on agentic commerce, where networks have been aggressively positioning the verifiable intent and trusted agent layers, will tell you whether they see the next decade through the lens of defending interchange or replacing it.

The $200 billion deal is not really about $200 billion. It is about whether the next two decades of card payments look like the last two.
