The first half of 2026 highlighted two competing M&A strategies in merchant acquiring.
In January, Global Payments completed its $24bn acquisition of Worldpay, doubling down on scale and processing volume. Months later, Adyen departed from its long-standing build-only philosophy with acquisitions of Talon.One and Orb, adding loyalty and billing capabilities rather than payment volume.
Both strategies have logic behind them. Both also carry significant risks. Ultimately, however, the deciding factor is neither size nor synergy – it is customer value.
Strategy one: Buying volume
The traditional acquiring playbook is built on consolidation. Acquiring competitors brings merchant portfolios, local licences, banking relationships and processing volume that would take years to build organically. In an industry with high fixed costs, greater scale should improve economics by spreading compliance, fraud prevention and technology investment across more transactions.
The approach has shaped much of the sector’s evolution, from Nexi and Worldline to Nuvei and Paysafe, with Global Payments’ acquisition of Worldpay representing its largest expression yet.
The challenge is migration. Cost synergies depend on moving merchants onto a common platform, yet payment integrations are often highly customised and business-critical. Merchants rarely welcome disruption for what appears to be a like-for-like proposition, leaving acquirers operating multiple legacy systems long after deals complete. Worse still, forced migrations can trigger customer churn, undermining the very scale the acquisition was designed to create.
Strategy two: Buying scope
The alternative strategy is to keep the payments engine intact while acquiring adjacent capabilities that deepen merchant relationships.
Adyen’s purchases of Talon.One and Orb follow this model, extending into loyalty and usage-based billing rather than acquiring transaction volume. Stripe has pursued a similar path through acquisitions in tax, reconciliation and merchant-of-record services.
The attraction is clear: broader software capabilities, greater share of wallet and stronger use of transaction data without the complexity of integrating another payments platform.
But scope carries its own risks. The success of firms such as Adyen and Stripe has been built on focus and engineering excellence around a single core proposition. Expanding into adjacent categories stretches management attention and product development while placing them against specialist competitors whose sole focus is loyalty, billing or tax software. The danger is that the differentiated payments proposition becomes diluted.
So which strategy wins?
We are deliberately not going to call it, because the honest answer is that the evidence does not yet exist, and the determining variable sits outside both deal models. The question that decides both strategies is the same: where is the customer value?
For volume deals, the test is whether the merchant ends up with something better than they had: a stronger product, broader geographic reach, better economics, a reason to migrate willingly rather than under duress. If the answer is a like-for-like offer on a different platform, history says the volume will not move, and the scale that drove the investment will stay trapped on legacy stacks.
For scope deals, the test is whether merchants genuinely want loyalty, billing or stablecoin infrastructure from their payments provider, and whether the combination produces something a specialist cannot: real-time decisioning fed by transaction data, one contract, one data model. If the answer is a bundle of adequate adjacent products wrapped around an excellent core, the core will carry the bundle for a while, and then the focus premium will erode.
It is entirely possible both succeed, in different segments: volume consolidation in the cost-driven mainstream of acquiring, scope expansion at the premium end of enterprise commerce. It is equally possible both disappoint, for the reasons their own histories suggest.
The first half of 2026 has given the industry a rare natural experiment: the two most consequential players in merchant acquiring have placed large, public and opposite bets on the value created by M&A. The deals were priced on synergies and addressable markets. They will be judged on whether merchants get a better acquiring offer. On that, only time will tell.
