Amex Just Tripled Your Runway Before You Need a Direct Agreement

What the OptBlue threshold change means for merchants scaling their American Express volume

Most merchants have no idea Amex just tripled a number that used to force them into a harder, and more expensive, relationship with American Express. Here's what changed, and why it matters if you're scaling.

The Old Rule

Once your American Express volume crossed one million dollars a year, you were pushed off OptBlue and into a direct agreement with Amex, known as an Establishment Service Agreement (ESA). That relationship comes with its own underwriting, its own risk review, and its own set of hurdles.

What Changed

Effective April 17, 2026, that threshold jumped to three million dollars. Merchants processing under three million dollars in Amex volume can now stay on OptBlue, meaning their existing processor keeps handling the Amex relationship instead of the merchant dealing with Amex directly.

Why It Matters

Direct Amex underwriting has always been one of the harder walls for merchants to climb, particularly without an established U.S. operating history. This change buys growing merchants three times the runway before they have to face that wall at all.

It's Not Just Easier, It's Cheaper

OptBlue rates are consistently lower than Amex Direct rates, since Direct pricing carries higher interchange without the wholesale-rate structure OptBlue processors receive. Merchants who would have been forced into pricier Direct rates at one million dollars now keep OptBlue's better pricing all the way to three million.

The Takeaway

If you were tracking toward that old one-million-dollar ceiling and planning around it, that plan just changed for the better. It's worth revisiting your processing strategy now that the runway before a harder, pricier relationship with Amex has tripled.
