Worldpay and the Acquirers Being ReplacedWide moat
Adyen (ADYEN) — moat facet
Most of Adyen's growth is not new commerce; it is fifteen years of replacing acquirers whose scale never became a product.
Most of Adyen's growth has not come from winning new commerce; it has come from replacing legacy acquirers. Worldpay, Global Payments and the bank-owned processors hold extensive acquiring reach and enterprise relationships built over decades1, and they run on systems assembled through acquisition — different platforms in different countries, stitched together with reconciliation.
That is exactly the weakness Adyen was designed to exploit. A merchant operating in twenty countries through a legacy acquirer has twenty integrations, twenty settlement processes and no consolidated view of authorisation performance. Adyen offers one. The moat pages describe this as the single-platform advantage; competitively, it is a fifteen-year programme of displacing incumbents whose scale never converted into a coherent product.
The incumbents are not standing still, and consolidation has given them more capital to modernise with. But rebuilding a payments platform while running the old one is genuinely hard, and the record of large processors attempting it is poor — which is why the replacement cycle has run as long as it has.
Watch Adyen's net revenue growth in mature markets specifically. Growth there is displacement rather than market expansion, and it is the clearest measure of how much of the legacy base is left to take.
The replacement cycle continues to run in Adyen's favour. Legacy acquirers hold extensive reach on platforms assembled through acquisition, and rebuilding one while running the old one has a poor track record across the industry. Consolidation has given the incumbents more capital to modernise with, and has not yet produced a coherent competing product.
Much of Adyen's growth comes from replacing legacy acquirers at large merchants. Volume growing faster than revenue shows those wins arriving at lower take rates, as large merchants negotiate.
