Global Payments

Global Payments generates $9.2B revenue, edging out #9 Worldpay by $200M, while processing 200B+ transactions through its integrated software ecosystem. The 2019 $21.5B TSYS acquisition created an end-to-end giant serving 100+ countries — a deal 16% larger than Worldpay's separation. Its per‑merchant revenue is 25% higher than the typical rival, reflecting a focus on high‑value embedded payments.
