Verticals

Overview

Payment Processing & Acquiring covers merchant-acquiring processors, ISOs, and payment facilitators that enable card and digital payment acceptance. It is the largest and most established fintech category, led by scaled processors (Fiserv, FIS, Global Payments) and modern platforms (Stripe, Block/Square, Adyen, Toast) that bundle payments with software.

Revenue scales with payment volume and the shift to digital and card-based spending, producing strong recurring economics. The defining trend is the bundling of payments into vertical software (integrated payments), which has reshaped distribution and driven heavy M&A.
