Visa was the first credit card network—a payment infrastructure that allows a consumer's bank to "talk to" a merchant's bank when they make a purchase. Today, Visa holds more than half of US credit card market share by purchase volume, with a global business that processed about 257.5 billion transactions worth about $14T in 2025.

When you buy even something as small as a $5 latte, a global relay between banks and networks like Visa and Mastercard is triggered. It all started with a 1958 campaign from Bank of America that jump-started the credit card revolution.
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%.
Visa was previously called National BankAmericard Inc. (NBI), but as other banks began to license the network and it expanded internationally, it needed a name less associated with both Bank of America and America itself. Hock believed that the word "Visa" implied no national identification and was relatively easy to pronounce in any language.
At the time, those credit cards were called "BankAmericards." Today, Bank of America owns less than a 2% share of Visa—many other banks (as well as institutional investors) help govern and profit from the network.
Visa gets roughly 0.13% to 0.14% of each transaction. About 32% of its revenue stems from the money banks pay Visa to use its services, and roughly 26% of its revenue comes from international transaction fees.
Every tap sets off a lightning-fast relay. When someone buys coffee with their Visa, a tiny "runner" races between the coffee shop's bank, Visa's network, and their bank—all in under a second. The catch? No money has actually moved yet. Here's what really happens behind that instant "Approved."
Hock was arguably an unlikely candidate for the founder of one of the most successful banking organizations of all time. He grew up extremely poor in rural Utah without indoor plumbing, but would go on to create one of the most innovative financial technologies of the 20th century.
On a 1958 morning in Fresno, California, about 60,000 people woke up to find a strange rectangular piece of plastic on their doorstep without explanation. Those chosen for the "Fresno Drop" didn't know it yet, but Bank of America was behind the credit card delivery stunt.
Each card network charges merchants a discount rate, which is a fee merchants pay to accept cards. American Express charges higher discount fees than competitors like Visa and Mastercard as the business is more reliant on fees for operation.
Because stablecoins operate on public blockchains, transfers can occur nearly instantly without intermediaries, unlike traditional credit card networks. This has fueled stablecoins' adoption within the crypto world and in cross-border payments. Stablecoin transfer volume rose from about $3B in 2018 to roughly $18T in 2024, overtaking Visa's roughly $16T and Mastercard's $10T.
The United States is home to more than 33 million businesses, the vast majority of which are small businesses, with millions being created (and others closing shop) every year. These businesses often rely on loans, provide the goods and services that keep the economy flowing, and sometimes even grow large enough to enter public markets or provide private investment opportunities.
