Payment processors and networks authorize, clear, and settle electronic payments — credit cards, debit cards, digital wallets, and cross-border transfers. Global non-cash transaction volumes reached approximately 1.4 trillion transactions in 2023 and are forecast to grow at a 15% CAGR to roughly 2.8 trillion by 2028 (Capgemini World Payments Report 2024). est. Visa alone processed 257.5 billion transactions on $14.2 trillion of payment volume in its fiscal year 2025 (ended September 2025). The five companies here span three distinct business models: card networks (V, MA), digital payment platforms (PYPL, XYZ), and bank/capital-markets payment infrastructure (FIS).
The card networks (V, MA) carry no credit risk, hold no consumer deposits, and lend no money. They earn a fee — measured in basis points — on every transaction that touches their rails. PayPal and Block sit on top of those same rails as overlay platforms, adding checkout, peer-to-peer transfer, and merchant services. FIS sells the back-office plumbing that banks and capital-markets firms use to process payments and trades.
When a consumer taps a card at a store, the transaction travels from the merchant's bank (acquirer) through the network (Visa or Mastercard) to the consumer's bank (issuer). The network authorizes, clears, and settles the transaction. The network charges three categories of fees: service fees based on payment volume, data processing fees per transaction switched, and international transaction fees on cross-border volume. From these gross fees, the networks pay back client incentives — rebates to large issuers and merchants — which reduce net revenue. Visa's client incentives were $15.8B in FY2025, roughly 28% of gross revenue (Visa FY2025 10-K). The networks take zero credit risk — that sits with the issuing bank.
Visa's FY2025 net revenue breakdown: service revenue $17.5B, data processing $20.0B, international transactions $14.2B, other $4.1B, minus client incentives of $15.8B = net revenue of $40.0B (Visa FY2025 earnings release). Mastercard's CY2024 net revenue was $28.2B with a similar structure (Mastercard CY2024 10-K).
PayPal operates as a two-sided network connecting 439 million active accounts (CY2025) to merchants. It charges merchants a percentage of each transaction — the "take rate" — which was approximately 1.66% ($0.02 per dollar) in 2025 (PayPal CY2025 10-K). PayPal's total payment volume was $1.79 trillion in CY2025. Revenue splits into transaction revenue ($29.8B) and value-added services including credit ($3.4B). PayPal also owns Venmo (peer-to-peer) and buy-now-pay-later via the Paidy and Happy Returns acquisitions.
Block operates two ecosystems: Square (merchant point-of-sale, $228B GPV in CY2024, serving 4+ million sellers) and Cash App (57 million monthly transacting actives in the U.S.). Square charges merchants per-transaction fees (typically 2.6% + $0.10). Cash App generates revenue from peer-to-peer instant-transfer fees, Cash App Card interchange, Bitcoin trading, and Afterpay (buy-now-pay-later). Full-year 2024 revenue was $24.1B, but gross profit was $8.9B — the difference is largely pass-through Bitcoin revenue (Block CY2024 10-K).
FIS sells software and processing services to banks and capital-markets firms. After selling 55% of its merchant-acquiring business Worldpay in January 2024 (and announcing sale of the remaining 45% stake for $6.6B in 2025), FIS now has two segments: Banking Solutions ($6.89B revenue in CY2024) providing core banking, digital channels, and card processing to financial institutions; and Capital Markets Solutions ($2.98B) providing trade processing, treasury, and risk management to buy-side and sell-side firms. Revenue is predominantly recurring (subscription and processing fees). FIS is also acquiring Global Payments' Issuer Solutions business for $13.5B, expected to close H1 2026 (FIS Q1 2025 earnings release).
Payment networks are not capacity-constrained in the traditional sense. Unlike power plants or semiconductor fabs, the cost of processing an additional transaction is near zero once the network exists. Visa's VisaNet processes over 65,000 transactions per second at peak, and scaling is a software/hardware investment, not a physical-resource bottleneck. The binding constraints are:
No new card network has achieved meaningful scale in decades. China's UnionPay succeeded domestically through government mandate but has limited penetration outside China. Discover was acquired by Capital One in 2025. Real-time payment rails (FedNow in the U.S., UPI in India, Pix in Brazil) are government-sponsored alternatives that bypass card networks entirely — U.S. uptake of FedNow remains nascent.
Demand for electronic payment processing is growing at low-to-mid-teens percentages globally (15% CAGR in non-cash transaction counts, per Capgemini). est. The ability to process transactions is effectively unlimited for incumbent networks — marginal cost per transaction is near zero. Growth accrues to whoever already holds the network position.
Pricing direction: Average take rates for the card networks have been roughly stable over the past decade despite regulatory pressure (Durbin Amendment, EU interchange caps). Visa's effective yield is approximately 15.5 basis points on payment volume ($40B net revenue / $14.2T = ~28 bps gross, ~15.5 bps after client incentives). est. The networks offset individual fee-rate compression with three levers: (1) higher transaction counts from cash displacement and contactless adoption, (2) cross-border volume growing faster than domestic (higher fee rates), and (3) value-added services — fraud detection, data analytics, tokenization — priced separately and growing 20%+ annually for both networks. est. PayPal's take rate has been declining (1.66% in 2025 vs. higher historically, down ~4.8% per year over five years) as it shifts toward larger merchants and branded checkout competes with unbranded processing. est.
