American Express

American Express caters its business to wealthy cardholders

American Express cards charge high annual fees, but also offer significant rewards and credits. It's just one way the company targets affluent customers who spend higher dollar amounts per transaction and tend to have more transactions than the average cardholder. This strategy decreases the company's risk, since it actually offers credit instead of just acting as a card network.

Two of American Express' co-founders also founded Wells Fargo

Henry Wells and William Fargo formed Wells, Fargo & Co. two years after American Express was created. Wells and Fargo saw an opportunity to expand the express delivery service from the East Coast and Middle America to the West Coast. The two initially asked the American Express board to expand operations, but the board declined, so they decided to create their own company. Today, Wells Fargo is among the top four largest banks in the US.

In 1882, American Express began offering money orders to compete with the US Postal Service

Money orders were American Express' first move into financial services. USPS launched its money order service in 1864 as a way for Civil War soldiers to send money back home. Between the 1880s and 1920s, immigration into the United States surged;the American Express money order service gave immigrants a way to send money to family members living in other countries.

American Express debuted its first charge card in 1958 to give travelers access to cash abroad

The original American Express charge card was made of purple paperboard and allowed customers to book travel. Unlike credit cards, the card's balance had to be entirely paid off each month. When the card first launched, 250,000 customers used it, and 17,500 companies had agreed to accept it.

American Express is both a card issuer and a processing network

Unlike most credit card companies, American Express issues credit cards and processes payments—something called a closed-loop model. By offering both services, American Express profits from both interest and interchange fees, and also has access to more data on how customers spend their money so it can offer better perks.

Card issuers are financial institutions that open credit to customers, while card networks facilitate purchases between merchants and customers

Card issuers give customers credit cards, set rate limits, and collect payments. Card networks, on the other hand, dictate where credit cards can actually be used by managing relationships between the network and merchants. These networks make money on interchange fees, which merchants pay to accept a specific card network at their stores.

Visa, the first credit card network, still dominates competitors with a roughly 52% market share by purchase volume.

Among the major credit card companies in the US, Mastercard had about 25% of the market share in 2025. American Express had roughly 20%, and Discover had the smallest market share of about 4%.

American Express runs on a 'spend-centric' model, using perks and merchant fees to drive profit

American Express cardholders tend to spend more money per transaction than other credit card users, which makes the interchange fees merchants have to pay to accept American Express cards worth it while incentivizing other companies to pay the interchange fee as well.

See a timeline of American Express' history

Since its founding in 1850, American Express has evolved from a mail delivery service to a multinational financial services company. Small additions to the company over time, such as taking money orders and inventing traveler's cheques, were key drivers of the company's transformation.

The 'Centurion' card is American Express' highest tier, invite-only credit card

The Centurion card or "black card" debuted in 1999 and created the trend of credit card companies' most exclusive cards being black. Centurion cards are technically invite-only, but you can fill out a form to request being considered for the card. It has a $5K initiation fee and a $5K annual fee.
