With a market cap of nearly $500 billion, Mastercard (NYSE: MA) is a true corporate giant. Indeed, it ranks as the 16th-largest American company by market cap, ahead of other financial behemoths like Bank of America, Wells Fargo, American Express, and Morgan Stanley.

But why? And perhaps more importantly, will Mastercard retain its place in the years to come? Let's find out.

Like its chief rival Visa, Mastercard has a business model based on payment processing. The company operates a vast network that facilitates payment transactions between merchants, cardholders, and card-issuing institutions.

In other words, Mastercard is the classic middleman. It charges fees for the use of its network. And while -- broadly speaking -- each individual fee is tiny, they really add up.

Over the last 12 months, Mastercard generated $29 billion in revenue. That's up about 12% from a year earlier when the company generated $26 billion in revenue. The increase is thanks to growing global payment volumes as the world steadily moves closer to a cashless society. In particular, emerging market economies continue to transition away from cash and toward cards as living standards increase and internet access expands.

Moreover, Mastercard's network benefits from economies of scale. That is, as the network grows in size, Mastercard can derive more and more profit from it, as the benefits of the network grow faster than its costs.

Indeed, over the last 10 years, Mastercard's operating margin has increased from 53% to 58%, while its net income has soared from $3.7 billion to more than $13.1 billion.

After reviewing its business model, it's no wonder that Mastercard stock has advanced by leaps and bounds. In fact, Mastercard has been one of the best stocks to own over the last 10 years, with a 10-year total return of 518%, easily outpacing the S&P 500's total return of 246% over the same period.

Supporting this excellent performance is Mastercard's solid mix of dividend payments and share buybacks. The company currently pays a modest quarterly dividend of $0.76 per share, generating a dividend yield of 0.55%. Mastercard also announced a $12 billion share repurchase plan in December of 2024, which will help drive shareholder value by reducing outstanding shares.
