What Is American Express (Amex)? Understanding the Global Payments and Financial Services Company
What Is American Express (Amex)?
When people see an American Express card, they often think of it simply as a credit card brand.
But American Express, commonly known as Amex, is much more than a company that provides credit cards. It operates across payments, card issuing, merchant services, lending, banking, travel, rewards and business expense management.
That makes American Express different from companies that primarily operate payment networks.
Understanding what Amex actually does helps explain its cards, rewards programs, merchant relationships and financial services, as well as its position in the global payments industry.
American Express in Simple Terms
American Express is a global payments and financial services company headquartered in New York.
Founded in 1850, the company has evolved from its early transportation and financial-services businesses into a technology-driven payments company serving consumers, small businesses, large corporations and merchants around the world. American Express: Who We Are
Today, Amex operates through four major business areas: U.S. Consumer Services, Commercial Services, International Card Services, and Global Merchant and Network Services.
The company describes this as an integrated payments platform.
That word integrated is important.
American Express can participate in several parts of a payment transaction rather than operating only as the network connecting separate banks and businesses.
The Amex Business Model
To understand Amex, it helps to look beyond the card itself.
American Express can:
- Issue cards directly to consumers and businesses
- Operate its own payment network
- Maintain direct relationships with merchants
- Provide credit and financing
- Offer rewards and membership services
- Provide travel and lifestyle benefits
- Help businesses manage expenses and payments
- Provide banking and other financial services
This gives the company relationships with both sides of a transaction: the customer using the card and the merchant accepting it.
That structure also allows American Express to build products and services around the spending relationship rather than treating payment processing as a standalone activity.
How an Amex Payment Works
Consider a customer paying for a $500 hotel stay with an American Express card.
The customer uses the card, the hotel accepts American Express, and the transaction moves through the Amex network.
If American Express issued the card, it also manages the cardholder relationship and takes responsibility for the associated credit risk.
At the other end, Amex maintains a relationship with the merchant and can provide payment processing and additional services.
That creates a more direct connection between the cardholder, merchant and payment network.
American Express says its integrated model can provide information from both sides of the transaction, supporting areas such as fraud prevention, credit decisions and personalized services.
How American Express Makes Money
American Express has several sources of revenue rather than relying on a single payment-processing fee.
Its business generates revenue from card spending, lending, fees and merchant-related services.
In 2025, American Express reported $72.2 billion in total revenues net of interest expense, an increase of 10% from 2024. The company said growth came across spending, lending and fee revenues.
Merchant-related revenue is another important part of the model. Merchants pay for accepting and processing American Express transactions, while Amex also provides services such as fraud prevention, marketing capabilities and data analytics.
Lending provides another revenue stream.
Because American Express issues cards and offers financing products, it can earn interest from customers who carry balances or use other forms of credit.
The company also charges fees on various products and services.
This combination of payment, lending and fee-based revenue gives Amex a business model that extends well beyond operating a card network.
The Membership Model
One of American Express’s most recognizable features is its membership-based approach.
The company does not simply try to put a card in a customer’s wallet. It aims to build a broader relationship around spending, rewards, travel, dining and other services.
American Express refers to this as its Membership Model, with products and experiences designed to increase the value of staying within the Amex ecosystem. American Express shareholder information
Depending on the card and market, that ecosystem can include:
- Membership Rewards
- Travel services
- Airport lounge access on eligible products
- Dining experiences
- Hotel and airline partnerships
- Purchase-related benefits
- Business expense-management tools
- Digital financial services
The business logic is straightforward: useful benefits can encourage customers to use their cards more frequently, while greater spending can increase the value of the customer relationship.
Why Amex Has a Strong Premium Presence
American Express has built a significant presence in premium consumer and business payments.
That does not mean every Amex product is a premium card. The company offers products for different customer segments.
However, travel, dining, rewards, service and other experiences have played an important role in its strategy.
This gives Amex another way to compete in payments.
Instead of competing only on whether a card can complete a transaction, the company can build value around what happens before and after the payment.
That includes rewards, merchant offers, travel services, customer support and partnerships.
In 2025, American Express added 12.5 million new proprietary cards and ended the year with 152.8 million cards-in-force across its global network, according to its 2026 proxy filing. The company also reported more than 170 million American Express-accepting merchant locations worldwide.
American Express Cards: Credit and Charge Products
American Express is historically associated with charge cards, but its current portfolio includes both charge and conventional credit products.
A traditional credit card generally allows customers to carry a balance from one billing period to another, subject to the card’s terms and interest charges.
Charge-card products have traditionally been structured around paying the billed balance in full, although the specific features of modern Amex products vary.
The distinction is useful because American Express’s history includes a major role for charge cards, while its current business also includes revolving credit and other financing products.
What American Express Does for Businesses
Amex is not only a consumer card company.
Businesses are an important part of its model, ranging from small companies to large corporations.
American Express provides commercial cards, expense-management products, business financing and other payment solutions designed to help companies manage spending and financial workflows.
These services can cover areas such as:
- Employee spending
- Business travel
- Corporate expenses
- Supplier payments
- Expense reporting
- Working-capital needs
The company has also expanded its commercial technology capabilities. Its acquisition of Center, an expense-management platform, is an example of how Amex is moving beyond traditional card products.
This reflects a broader shift in financial services: payment companies increasingly compete to manage the financial processes surrounding a transaction, not just the transaction itself.
The Merchant Side of Amex
The merchant relationship is another important part of the American Express model.
Amex works with merchants that accept its cards and provides more than basic transaction processing.
Its merchant services can include:
- Payment acceptance
- Fraud prevention
- Transaction processing
- Marketing tools
- Customer insights
- Data analytics
- Business services
These relationships matter because American Express needs both sides of its ecosystem to remain valuable.
Customers need places where they can use their cards, while merchants benefit when Amex customers bring spending to their businesses.
That creates a two-sided network in which cardholders and merchants reinforce the value of the platform.
How Large Is the Amex Network?
American Express has a substantial global network, although its scale should not be measured using exactly the same metrics used by every other major payments company.
In 2025, American Express reported:
- $1.897 trillion in network volume
- $1.670 trillion in billed business on cards issued by Amex
- 152.8 million cards-in-force across its network
- 86.6 million proprietary cards-in-force
- More than 170 million accepting merchant locations worldwide
The network is also not limited to cards issued directly by American Express.
The company works with third-party financial institutions that issue Amex-branded cards or acquire merchants onto its network.
In 2025, third-party-issued cards accounted for 66.2 million cards-in-force, while worldwide processed volume from third-party-issued cards and alternative payment solutions reached $227.2 billion.
This shows how Amex has expanded its network beyond its traditional direct-issuance model.
Technology Is Becoming More Important
American Express may be best known for cards, but technology is increasingly central to its business.
Payment authorization, fraud detection, mobile applications, digital wallets, customer service, data analytics and expense management all depend on technology infrastructure.
Artificial intelligence is also becoming part of the company’s view of the future of payments.
In its 2026 shareholder letter, American Express discussed the potential for AI and software agents to discover products, make decisions and complete transactions on behalf of consumers and businesses. American Express shareholder information
If this develops at scale, the role of payment companies could change.
Customers may increasingly rely on digital systems to select payment methods based on factors such as rewards, security, preferences and price rather than manually choosing a card for every transaction.
Where Amex Fits in the Global Payments Industry
American Express occupies a distinctive position in the payments industry because its business crosses several financial-services categories.
It operates a payment network, but it also has direct relationships with cardholders and merchants.
Its activities extend into:
- Consumer payments
- Commercial payments
- Credit and lending
- Merchant services
- Rewards
- Travel
- Dining
- Expense management
- Banking
- Data and technology
That makes it more accurate to describe American Express as an integrated payments and financial services company with a global card network than simply as a credit-card company.
The distinction matters because the company’s performance depends on several interconnected relationships.
Consumer spending affects card volume. Card volume affects merchant activity and network economics. Credit products create lending revenue but also expose the company to credit risk. Rewards and services can influence customer engagement, while merchant acceptance affects where customers can use Amex.
Why Amex’s Business Model Matters
American Express illustrates how modern payment companies have expanded beyond the basic act of moving money from one account to another.
The card is the most visible part of the business, but behind it sits a much larger ecosystem connecting consumers, businesses, merchants, financial services and technology.
That model also helps explain why Amex has invested heavily in rewards, travel, business payments, merchant services and digital capabilities.
In 2025, the company generated record revenue of about $72 billion, while card spending, lending and fee revenue all contributed to growth.
The future of American Express will therefore depend on more than the number of cards it issues.
Its long-term position will also be shaped by consumer spending, business payments, credit conditions, merchant acceptance, technology and how the wider payments industry evolves.
American Express is ultimately not just a card brand. It is a global financial ecosystem built around payments, credit, merchants, rewards, services and technology.
That broader structure is what makes Amex different and what makes the company worth understanding as part of the global payments industry.
