Using the 2025 edition, TSG has published new insights on the country’s merchant acquiring landscape below. Read additional findings and insights.
- The top five players processed an estimated $8 trillion in card volume in 2024. All five players have a strong bank sales channel, as they are either bank-owned or have bank partners/clients from other areas of their business.
- Nearly 60% of the volume represented in the directory is processed by these top five players, and almost 90% of the volume represented in the directory is processed by the top twenty-five listed players
- Authorize.net (a Visa solution) is the payment gateway with the most partnerships among the acquirers listed, partnering with 41% of these players, a similar percentage as last year
- 41% of the players listed sell Fiserv’s Clover point-of-sale products. This is up from 38% of providers that listed Clover as an available smart POS offering.
- It’s impressive to have over a million domestic clients—only Square, Stripe, QuickBooks Payments, Global Payments, and Worldpay hit that threshold.
- With its predominant focus on restaurants, Toast continues to amass considerable market share, registering as the 14th largest provider by processing volume.
- Integrated sells – 72% of the top 50 listings by volume utilized the ISV sales channel.
