For over a decade, the Amex OptBlue threshold sat at $1 million. If your Amex volume crossed that line in a rolling 12-month period, you were pushed off OptBlue and forced into a direct agreement with American Express.
That line quietly moved to $3 million on April 17, 2026. And most of the industry hasn’t updated accordingly.
Amex Raised the OptBlue Threshold From $1 Million to $3 Million
This is the first time that American Express has adjusted its threshold for a direct agreement requirement since the OptBlue program launched back in 2014.
- The new $3 million threshold is based on Estimated Annual Charge Volume (ECV), which is measured on a rolling 12 months.
- If you’re under $3 million in Amex volume, your existing processor can handle Amex alongside Visa, Mastercard, and Discover.
- If you’re already on an Amex Direct agreement, you’re not being kicked off.
- Merchants under $3 million are not eligible to move back to OptBlue (which is optional, and not automatically the right call).
The group with the most to gain here is the one that nobody is really talking about just yet: businesses sitting on an Amex Direct agreement around $1 to $3 million in volume.
They only signed a direct agreement because the old threshold forced them to. But now, there are more options at your disposal.
Exceptions to the $3 Million Threshold
It’s worth noting that the new $3 million number does not apply universally. There are two exceptions:
1). Puerto Rico and the US Virgin Islands are excluded. Businesses operating in those US territories mentioned above can continue to operate under the prior threshold.
2). Eight industry categories have no volume ceiling on OptBlue eligibility:
- Charity
- Healthcare
- Education
- Government
- Insurance
- Residential Rent
- Utilities
- Online Gambling
This isn’t new, but it’s misunderstood. If you’re a hospital system, municipality, insurance carrier, or property management company, volume has never been what determines your OptBlue eligibility.
Amex notes that not every MCC code inside a given industry qualifies. So the MCC assigned to your specific account is what dictates the qualification for your business. For example, Online Gambling and Games of Value carries its own conditions, including a minimum charge volume and a requirement for the processor to be certified separately.
Which Program Costs Less?
The standard line you’ll hear is that OptBlue is cheaper than Amex Direct. And sometimes it is, but it’s not a firm rule.
These two programs are priced in fundamentally different ways.
With Amex Direct, you pay for everything straight to American Express without a processor sitting in the middle taking a cut. What Amex quotes you is largely close to what you pay, and it stays relatively flat across all transaction sizes.
Rates could be higher here. But it’s all legit, and there’s no junk fees to sort through that inflate your effective rate. It’s pretty straightforward and transparent. (Read more: Amex Direct Statement Audit)
On OptBlue, your cost is built in layers. There’s the Amex wholesale interchange rate, plus network assessments, and your processor’s markup stacked on top.
Some processors are good about just charging you a fair per-transaction markup over interchange. While others add additional fees and hidden markups to artificially inflate your rates. So even though the base rate might seem cheaper, it could be more expensive all in.
Ticket size is another important variable that needs to be evaluated here. OptBlue rates are banded by transaction amount within each industry category, and the rates climb with the transaction amount. So a restaurant averaging $70 per transaction could sit on a much cheaper rate than a B2B distributor averaging $6,000 per transaction.
If You’re Already on Amex Direct Between $1 Million and $3 Million
Historically, it didn’t matter which program was cheaper because you didn’t have much of a choice. Your volume was either within the OptBlue range or crossed a threshold that required a direct agreement.
But the latest OptBlue eligibility change opened the door for merchants on a direct agreement. If you’re sitting somewhere in that $1M to $3M range, you could go back to OptBlue.
To be clear, American Express isn’t going to cancel your ESA because the threshold moved. Your current agreement is still valid. All that’s changed is that you’re now eligible for something you were previously locked out of.
When it Makes Sense to Move Back to OptBlue
- Your average ticket value sits in the lower or middle OptBlue bands for your industry category, which are among the cheaper rates per transaction.
- Your processor is fair, transparent, and you’ve already negotiated favorable terms with them.
- Your processor will charge your Amex volume the exact same markup as other card brands.
- Separate Amex reconciliation is costing your finance team time and money every month.
When it’s Better to Keep Your Direct Agreement in Place
- A combination of high average tickets and your MCC puts you in the most expensive OptBlue pricing bands.
- Your processor prices Amex transactions at a premium markup and won’t budge.
- You’ve negotiated competitive rates on your Direct agreement that your processor can’t beat.
- Your rolling 12-month Amex volume is close to $3 million and still growing.
Not every processor is part of the OptBlue program. So if you’re using a smaller or niche-specific provider that doesn’t offer this, you’re better off sticking with them and keeping your direct agreement in place as opposed to switching processors just to get OptBlue.
How to Leverage This Change Into Cheaper Overall Processing Rates
Moving $2 million in Amex volume to your processor is worth real money to them. It’s revenue they’re currently not earning on your account. And the ability to add it to an existing account compared to onboarding a new merchant from scratch makes it even more profitable.
This presents a great opportunity to negotiate with your processor.
Don’t stop the conversation at what they’ll charge you for the new Amex volume. Ask them what your markup will look like across all four card brands now if you ultimately bring this added volume over.
Getting cheaper rates across the board makes the move back to OptBlue even more appealing if the numbers you were running strictly on Amex volume were negligible or on the fence.
Say your processor is charging you 0.20% + $0.10 per transaction on $6 million annual Visa, Mastercard, and Discover volume. Your effective rate is roughly 2.6% here, and 2.8% on your Amex ESA. 2 bps savings may not seem like it’s worth changing anything.
But if your processor is willing to drop your markup to 0.15% + $0.05 on all cards once the Amex volume moves over, it changes the math on your conversation. If you also target other markups on your account that could put your total effective rate closer to 2%, the switch may be worth it and you’ll set up savings long-term.
What the Transition From Direct to OptBlue Looks Like
If you’re below $3M in Amex volume and decide you’d rather be on OptBlue, the change isn’t just a flip of the switch.
Despite the new OptBlue eligibility rules, you’re still under contract with Amex Direct. But the good news about these agreements is that unlike standard processor contracts, most ESAs are month-to-month or can be canceled at any time.
Mechanically, this means your processor will re-register you with American Express for OptBlue.
But your ESA account needs to remain open during the transition to ensure you can continue accepting Amex cards uninterrupted. Your processor doesn’t have the ability to close this. Once all of that volume on every sales channel has officially moved to your processor’s rails, close the account with Amex and confirm this in writing.
Amex won’t end your relationship completely because they still need access to you for any disputes or chargebacks that occurred while you were on a direct agreement. So even if you’re no longer routing transactions through an ESA, your account may need to remain open and Amex may hold some funds as a precaution depending on your chargeback history.
Fees to Watch Out For Once You’re on OptBlue
Moving from Amex Direct to OptBlue can introduce new fees and problems that you didn’t previously have. Check these line items on your first few statements:
- An Amex markup that does not match your Visa and Mastercard markup.
- Amex-branded charges like “Amex Access Fee” or “Amex Support Fee” that sound legit but are just extra markups charged by your processor.
- Misaligned MCC or ticket tiers, which quietly overcharges your OptBlue volume on every transaction.
- Amex network assessments that are higher than the published rates.
This is the type of stuff that we see all of the time when auditing statements for our clients.
Some processors are more egregious than others. So some of you might only see one of these fee scenarios applied while others can see a combination of them all.
But none are ok. These billing tactics can spike your effective rate and erase any theoretical savings you accounted for when switching to OptBlue.
Those paper savings are useless if they aren’t actually being applied once payments start flowing.
Final Thoughts
If you’re under $3 million in Amex volume and already on OptBlue pricing today, nothing changes for you except that you have more room before you hit the threshold for a direct agreement.
But if you have a direct ESA with American Express and you’re sitting between $1 million and $3 million, this change could be a cost-saver for your business.
You now have the option to leave your direct agreement and get Amex OptBlue from your current processor.
The first thing you should do is pull your last few statements and calculate the effective rates from your processor and Amex. Is there a meaningful gap? If your processor is much cheaper, you have a lower average ticket value, and you’re nowhere near exceeding the new $3M threshold, it’s worth crunching the numbers.
And savings can be amplified if you leverage the change into a reduction across all transactions run through your processor.
