Top fintech companies by revenue: the 25 largest from their own filings

This list is for people who sell to fintech companies: compliance, fraud and identity vendors, cloud and data providers, customer support and collections firms, marketing agencies and recruiters. It ranks the 25 largest fintechs by revenue from their own annual reports, shows what each one's revenue is made of, and explains where the buying happens inside a regulated financial company.

The 25 largest fintech companies by revenue

Revenue is the top line of each company's latest Form 10-K or 20-F filed by 30 October 2026, and Adyen's 2025 annual report: "net revenue" for Visa, Mastercard, PayPal and Adyen, "total net revenue" (after interest expense) for SoFi, "revenue and reserve income" for Circle, and revenue net of interest expense for Wise. Adyen's euros are converted at the Federal Reserve's 2025 average rate of $1.1306. The change compares with the prior year in the same report. Headquarters are the business addresses on file with the SEC, and Adyen's head office. "Not used" means we didn't take a headcount from the filing.

What the revenue is made of

Fintech revenue isn't one thing, which is why the order surprises people:

• Block reported $8.50 billion of bitcoin ecosystem revenue, mostly the price of bitcoin sold to Cash App customers, alongside $11.51 billion from commerce enablement and $4.18 billion from financial solutions. Take bitcoin out and Block's $15.69 billion would rank eighth, just behind Nubank's $15.77 billion.
• Circle earned $2.64 billion of its $2.75 billion as reserve income, interest on the assets that back its USDC stablecoin, so its revenue moves with interest rates.
• Visa and Mastercard report net revenue after incentives paid to clients. Visa's 10-K says it doesn't issue cards, extend credit or set cardholder rates; the issuing banks do.
• Global Payments reported its card-issuing business as discontinued operations in 2025, and its purchase of Worldpay closed in January 2026, after the year, so its 2026 revenue will look very different.
• Nubank is the largest fintech outside the US on this list, with $15.8 billion of total revenue, including $4.60 billion of credit card interest, $4.78 billion of loan interest and $2.34 billion of fees and commissions. It has 10,027 employees, 4,236 of them (42.2%) in technology.

How we built the list

1. Who counts. Companies whose main business is payments, financial software, digital banking or lending, trading or crypto, and that publish annual results. Traditional banks, card-issuing banks and insurers are left out, as are companies whose financial services are a small part of a larger business.
2. What's counted. The top line as each company reports it, including acquisitions from the date they closed.
3. Which year. The latest fiscal year reported by 30 October 2026. Visa's year ended 30 September 2025; its 2026 10-K was not yet filed.
4. What's left out. Private fintechs that don't publish annual results, however large their valuations, and listed fintechs outside the US that we didn't check, such as Worldline and Nexi in Europe and Paytm in India.

What the top results get wrong. TMA Solutions' list, second in Google for this search, ranks by market value from Statista with no date, puts private companies' valuations in the same column as listed companies' market values, and gives Tencent as $70 billion in its table and $494.59 billion in its text. Forage's list is titled 2026 but was last updated in September 2023: it shows Visa at $29.31 billion, against $40.0 billion in Visa's latest 10-K. Neither says which fiscal year a figure covers.

What the list is good for if you sell B2B

Every fintech is a regulated buyer. Payment companies, lenders and banks are supervised, and most of them will put your product through a third-party risk review before signing: security questionnaires, data protection terms and, for anything touching payments or customer data, audit reports. Build that into the timeline. Our guide to how B2B buyers build a shortlist covers what they look for.

General guidance, not taken from any one company's policies. Fintechs are lean for their revenue: Robinhood took $4.5 billion with about 2,900 full-time staff and Affirm $4.3 billion with 2,358, so a single team lead often owns a whole category of spend. Klarna's full-time headcount fell from about 4,352 in 2023 to 2,831 at the end of 2025, according to its 20-F, so check current team size before you size a deal. For the people who run these businesses, the largest banks list covers the traditional side of the market.

Worked example

Illustrative example. Clearpath (clearpath.example) sells compliance training for $8 per employee per month. Its seller sizes two accounts from their annual reports:

• Nubank: 10,027 employees. Full deployment: 10,027 x $8 x 12 = about $963,000 a year.
• Robinhood: about 2,900 full-time employees. Full deployment: 2,900 x $8 x 12 = about $278,000 a year.

The first deal is usually one function. At Nubank, the technology team is 4,236 people: 4,236 x $8 x 12 = about $407,000 a year, a budget the compliance and engineering leads can share. The seller targets the head of compliance training and the chief compliance officer's office, with the third-party risk review started in the first month. At volume, finding the right owner at each fintech is the slow part; Bebop researches each account in a list and finds the people.
