Largest payment providers in Europe

No published figure covers every kind of payment provider, so the twenty providers stand in three groups, and each group is ranked by one measure. Group A ranks payment service providers and acquirers by the payment volume they processed in their latest full year. Group B ranks wallets, payment apps and buy now, pay later by active or registered users, and group C ranks neobanks, fintech accounts and money transfer services by customers.

A rank compares a provider only with the other providers of its own group, so the seventh place of Klarna says nothing about its size next to Trustly in sixth place. Most companies publish one figure for their whole group, and for Adyen, Klarna and Revolut that figure includes customers outside Europe. Each section below names the period of its figure and says when a figure covers more than Europe.

A payment service provider connects a shop to cards, wallets and bank payments through one contract and one technical integration. Most companies in this group also act as the acquirer, which means they hold the license to accept card payments for the merchant and pay out the money. The measure in this group is the value of all payments a provider processed in one year, which is the figure that acquirers report to their investors.

Adyen is a payment platform from Amsterdam that processes online, in-store and in-app payments for large merchants and platforms on one global system. Adyen processed €1,394.3 billion in 2025 and earned net revenue of €2,364.2 million, and both figures cover its business worldwide. Adyen holds a banking license from De Nederlandsche Bank and acquires the card payments of its merchants itself.

Nexi is a payment company from Milan that runs card acceptance, payment terminals and card processing for merchants and banks in Italy, the Nordic countries, Germany, Austria, Switzerland and Poland. Its Merchant Solutions business handled transactions worth €837.0 billion in 2025, and the group reported net revenues of €3,585.2 million for the year. In Germany Nexi works through Nets and Concardis, and since September 2025 it has been the sole owner of the payment gateway Computop from Bamberg.

Worldline is a French payment company with its head office at Paris La Défense, and it supplies terminals, online checkout and acquiring to about 1.2 million merchants. Worldline publishes no audited merchant sales value for the full year 2025, but its Capital Markets Day presentation put acquiring volume at €480 billion on an estimated pro forma basis for that year. In the fourth quarter of 2025 alone, Worldline acquired merchant sales of about €146 billion, and the group reported revenue of €4,030 million for 2025.

Checkout.com is a London payment processor for large online merchants and digital platforms that sell to customers in many countries. Checkout.com processed more than $300 billion in total payment volume in 2025, 64 percent more than in the year before, across its business worldwide. The company returned to full-year profitability in 2025 and raised its net revenue by more than 30 percent for the second year in a row.

Mollie is an Amsterdam payment provider for small and mid-sized online businesses, which accept cards, wallets and local methods such as iDEAL through one account. Mollie completed its purchase of GoCardless on 1 September 2026, and the combined group serves more than 350,000 businesses in more than 30 markets. Mollie publishes no payment volume, so the rank rests on GoCardless, the London specialist for direct debits and bank payments, which processed more than $130 billion of payments a year when the deal was announced.

Trustly is a Stockholm company for pay by bank, where a customer pays a merchant straight from the bank account through open banking, without a card. Trustly processed SEK 1,059.0 billion in 2025, its first year above the mark of $100 billion, and it earned more revenue in the Americas than in Europe. Trustly connects more than 9,000 merchants, among them PayPal and Booking.com, with consumers through about 12,000 banks in more than 30 markets.

A wallet or payment app lets a person pay from a phone, by entering a mobile number, scanning a QR code or tapping a terminal. Most national payment apps in Europe belong to the banks of their country and move the money as an account-to-account payment in seconds. Klarna is the one provider in this group that also lends, since a buyer can split a purchase into installments or pay an invoice later. The group is ranked by active or registered users, as each company reports them.

Klarna is a Stockholm payment company that lets shoppers pay at once, pay after delivery or pay in installments, in its app and at the checkout of partner shops. Klarna had 118 million active consumers and 966,000 merchants at the end of 2025, counted worldwide, after a record 115,000 new merchants in the fourth quarter. Klarna holds a Swedish banking license, and its shares have been listed in New York since 2025.

Wero is the wallet of the European Payments Initiative, a Brussels company owned by European banks and payment processors, and it moves money between bank accounts in seconds with a phone number. Wero had about 60 million users in September 2026, with payments between people live in Belgium, France and Germany. German online shops have accepted Wero payments since the end of 2025, and the Dutch method iDEAL is due to move into Wero by 2027.

Bizum is the mobile payment service of the Spanish banks, and a user sends money to another person by entering a mobile number in the banking app. Bizum had more than 30.6 million users in 2025, who made 1,237 million operations in the year, 13.2 percent more than in 2024. Bizum also pays in online shops, and in 2025 the Spanish banks began to connect it with payment apps in other European countries.

BLIK is the mobile payment system of the Polish banks, where a customer confirms a payment in the banking app with a six-digit code at an online checkout or a shop terminal. BLIK counted 21.6 million active users at the end of June 2026 and processed 1.6 billion transactions in the first half of that year. The same code also withdraws cash at ATMs without a card, and customers send money to each other with a phone number.

Vipps MobilePay is the Nordic wallet that formed when the Norwegian app Vipps merged with MobilePay from Denmark, and the company is registered in Oslo. Vipps MobilePay had 12.4 million users in Norway, Denmark, Finland and Sweden at the end of 2025, among them 4.74 million Danish and almost 4.7 million Norwegian users. People use the app to send money to each other and to pay in shops or online with a phone number, a QR code or a tap.

Swish is the mobile payment service of the large Swedish banks and moves money between bank accounts in real time, with a mobile number as the address. At the end of 2024, almost 9 million individuals and more than 345,000 businesses were connected to Swish, according to the Riksbank. In a survey of the Swedish central bank from September 2025, 91 percent of respondents had used Swish in the past month.

Satispay is a Milan payment app that draws money from the bank account of the user and pays in shops, online and between friends. Satispay states 6.5 million customers and more than 450,000 affiliated shops, counting physical stores and online shops together. Satispay also sells meal vouchers to employers, and its users can save and buy shares and ETFs inside the same app.

TWINT is the Swiss payment app, and a user pays in Swiss francs by scanning a QR code at the checkout and confirming the amount on the phone. TWINT passed 6 million active users in the middle of 2025, after 773 million transactions in the year 2024. Five Swiss banks own TWINT together with SIX and Worldline, and the app also pays in online shops and on public transport.

A neobank runs its current accounts and cards through an app without branches, and its customers pay with those cards every day. Money transfer services such as Wise move money between currencies and countries, and broker banks such as Trade Republic added a current account and a card to their investment app. This group is ranked by customers as each company counts them, and some companies report every registered account while others count only active customers.

Revolut is a London fintech company with current accounts, cards, currency exchange and trading in one app, and it serves customers in the European Economic Area through its bank in Lithuania. Revolut had 68.3 million retail customers and 767,000 business customers at the end of 2025, counted worldwide, and its revenue grew by 46 percent to £4.5 billion. Revolut customers moved £1.3 trillion through the app in 2025, 65 percent more than in the year before.

bunq is a bank from Amsterdam with a Dutch banking license that runs accounts for private customers and businesses through its app in many European countries. bunq passed 20 million users across Europe in September 2025, when it marked ten years since the launch of its first app. bunq became the first bank to offer Wero for payments between people and online in the Netherlands, Germany, France and Belgium, and it holds more than €10 billion in user deposits.

Wise is a London money transfer company that sends money abroad at the mid-market exchange rate and runs multi-currency accounts and cards for people and businesses. Wise had 18.9 million active customers in the year to March 2026 and moved $243.5 billion across borders in that year, 31 percent more than a year earlier. Banks and fintech companies also use the Wise Platform to offer international transfers inside their own apps.

Monzo is a London bank that runs current accounts, savings and loans through its app under a full banking license in the United Kingdom. Monzo had 15.2 million customers in the year to March 2026, 3 million more than a year earlier, and its revenue rose to £1.7 billion. Monzo has also launched in Ireland with a license from the Central Bank of Ireland, its first market in the European Union.

Trade Republic is a Berlin broker and bank with a German banking license, where customers invest in shares, ETFs and savings plans and pay with a current account and a card. Trade Republic had more than 10 million customers with €150 billion in assets in December 2025, after its customer base doubled within 18 months. In the same month, a secondary sale of shares by early investors valued the company at €12.5 billion.

N26 is a Berlin bank with a German banking license that runs current accounts, savings and cards through its app for customers in 24 markets. N26 had 5.6 million revenue-relevant customers in 2025, 16 percent more than a year earlier, and it reported revenue of €501.6 million and its first full year of net profit. N26 counts only customers who bring in revenue, so its figure is stricter than the user totals of bunq or Revolut.

Starling Bank from London reported 6.2 million accounts in the year to March 2026, a count that includes accounts that other banks run on its Engine software. The ranking leaves Starling out because that count mixes its own customers with the customers of other banks, and no separate figure is published. The Paris business account provider Qonto serves small companies and freelancers and states more than 750,000 business customers in eight markets, fewer than N26.

Several payment providers that European merchants and consumers use every day have their seat in the United States, so they stay outside the European ranking. PayPal, which runs its European business from Luxembourg, had 439 million active accounts and $1.79 trillion in payment volume in 2025 worldwide. Stripe, with its European head office in Dublin, reports total payment volume of $1.9 trillion for 2025 across all its markets.

Fiserv accepts card payments for merchants in Germany through its unit TeleCash and reported revenue of $21.2 billion in 2025 without a separate European volume. Global Payments completed its purchase of Worldpay, an acquirer with a large business in the United Kingdom, in January 2026. Apple Pay publishes no user figure for Europe, and neither does Google Pay, because both wallets run on the cards that banks issue. Paysafe has its seat in London and its shares listed in New York, and it reported annualized transaction volume of $167 billion in 2025 across its business worldwide.

Visa is a card scheme, which means it sets the rules and runs the network that connects the bank of the cardholder with the acquirer of the merchant. A merchant signs a contract with an acquirer such as Adyen or Nexi, and a consumer gets the card from an issuing bank, so neither of them contracts with the scheme. International card schemes carried about 61 percent of card payments in the euro area in 2022, and 13 euro area countries rely on them for every card transaction. Both international schemes have their seat in the United States, and Mastercard runs its European business from Waterloo in Belgium.

European banks and central banks want more card and wallet payments to run on European systems, because in 13 euro area countries every card payment uses an international scheme. The European Payments Initiative built Wero for this purpose, on top of instant transfers between bank accounts in euros. National apps such as Bizum, Vipps MobilePay and the Portuguese MB WAY work together in the European Payments Alliance, which is connecting its apps with Wero for payments across borders. Vipps MobilePay names the goal of interoperability for more than 130 million users across Europe during 2026. Guy de Blonay, a fund manager at Jupiter Asset Management, wrote in 2020 for finews.ch (in German) that the five largest payment providers held more than 75 percent of the US market and less than 40 percent in Europe.

A merchant compares payment providers on price and on the payment methods that they accept in each country where the merchant sells. Price comes either as a blended rate per transaction or as interchange plus, where the provider passes on the interchange and scheme fees and adds its own margin. Larger merchants often connect two or more providers through payment orchestration, so that a declined payment can be retried with the second provider. Subscription businesses look for providers that handle recurring payments and card updates, and merchant acquiring covers the contract behind every card payment.

Adyen from Amsterdam is the largest payment service provider with its seat in Europe, with €1,394.3 billion in processed volume in 2025. Nexi from Milan follows with transactions worth €837.0 billion in its Merchant Solutions business in the same year. The US companies PayPal and Stripe process more money worldwide than either of them, but neither publishes a figure for Europe alone.

The Netherlands is home to Adyen, Mollie and bunq, and Sweden is home to Klarna, Trustly and Swish. The United Kingdom has Checkout.com, Revolut, Wise and Monzo, Italy has Nexi and Satispay, and Germany has Trade Republic and N26. France has Worldline, Spain has Bizum, Poland has BLIK, Norway has Vipps MobilePay and Switzerland has TWINT, while Wero comes from Brussels.

The largest merchant acquirers with their seat in Europe are Adyen, Nexi and Worldline, which accept card payments for merchants under their own licenses. By their own figures, Adyen and Nexi alone handled more than €2.2 trillion in 2025, and Worldline estimated its acquiring volume at €480 billion. Global Payments with Worldpay and Fiserv with its German unit TeleCash are US acquirers with large merchant businesses in Europe, and neither publishes a European volume.

Revolut is the largest neobank in Europe by customers, with 68.3 million retail customers worldwide at the end of 2025. bunq from Amsterdam follows with more than 20 million users across Europe, and Monzo from London had 15.2 million customers in the year to March 2026. Among the German app banks, Trade Republic passed 10 million customers, and N26 reported 5.6 million customers who bring in revenue.

Revolut earned £4.5 billion in 2025, more than any other of the twenty providers, followed by Worldline with €4,030 million and Nexi with net revenues of €3,585.2 million. Adyen earned net revenue of €2,364.2 million in 2025, and Monzo reported £1.7 billion in the year to March 2026. Revenue measures what a provider earns from fees and interest, so a provider with a high volume and low fees ranks higher by volume than by revenue.
