Adyen 2Q26: The New Denominator

Adyen is winning more wallet share.

Paradoxically, that makes the underlying payment cheaper.

H1 volume grew 24%, while revenue grew 21% and take rate fell to 16.2 bps.

That changes the thesis.

The question is no longer whether Adyen has better payment infrastructure. It is whether loyalty, billing, issuing and money movement can make the merchant relationship more valuable faster than payments commoditize.

My latest piece is about that new denominator.

Payments are getting cheaper. The merchant relationship has to become more valuable.

“We are no longer just a payments company. We are the complete financial operating system for modern commerce.”

There is one number in Adyen's first-half results that complicates that statement: 16.2 basis points.

Adyen processed €803.8 billion in H1, 24% more than a year ago, while net revenue increased 21% in constant currency. Digital revenue grew 15% against 17% volume growth, while even Platforms grew 40% against 42% volume. Adyen is winning more business, but the revenue attached to each euro of payment volume is declining as large merchants move into lower pricing tiers.

Six months ago we concluded that the old “architecture dividend” thesis needed an upgrade. Adyen's single platform was still differentiated, but we had confused evidence that the platform creates value with evidence that Adyen captures that value. As we wrote after Q1, “The single platform cannot merely process more volume. It has to help Adyen earn more around that volume.”

H1 is the first report that makes clear management has reached essentially the same conclusion.

The fundamental question is therefore no longer whether Adyen has superior payment infrastructure. It is whether Adyen can increase the total economics of a merchant relationship faster than scale commoditizes the underlying payment.

That is a harder question. It is also a much more interesting one.

The Merchant, Not the Transaction

The most important disclosure in H1 was not revenue or EBITDA. It was Adyen's newly disclosed customer maturity curve.

Roughly two-thirds of H1 growth came from merchants onboarded in 2024 or earlier. Typical wallet share rises from below 20% in years three through seven to above 40% after a decade, while the 300 merchants accounting for roughly 60% of growth represented more than 70% three years ago. That disclosure suggests a different way of measuring Adyen.

The traditional payment equation is straightforward: processed volume × take rate = revenue. The emerging Adyen equation is closer to merchant relationship × wallet share × workflows × products = economic value.

Consider how that might work. A merchant starts with online payments, adds more countries, then physical locations through Unified Commerce. Those transactions make Adyen's understanding of the merchant and shopper richer; Dynamic Identification and Uplift use that information to improve authorization and fraud outcomes. Talon.One can add loyalty and incentive decisioning before the transaction, Orb can meter and bill usage, while accounts, issuing and Intelligent Money Movement extend Adyen's role after the transaction.

The payment becomes the foundation rather than the entire product. There is, however, a crucial piece of information management did not provide.

Bryan Bergin asked where Adyen's existing customer base sits on the newly disclosed maturity curve: how much volume already comes from merchants above 40% wallet share versus customers earlier in their penetration journey. Management talked about diversification and continued expansion but did not give the requested mix.

That matters. Adyen has shown investors the slope of the curve but not where the installed base sits on it. If most volume remains early in the curve, the disclosure is a powerful forward indicator. If much of the business is already mature, it is more descriptive of the past. The non-answer does not prove the latter, but neither should we treat the former as established.
