Two ASX fintech shares stand out to me for their potentially enormous US growth opportunities. While both companies already have established businesses, their exposure to the world’s largest economy could provide another leg of growth.
For investors seeking ASX shares with international ambitions, Xero Ltd (ASX: XRO) and Zip Co Ltd (ASX: ZIP) are two names worth considering.
Xero: first moves in US$29 billion market
Xero is a cloud-based accounting software company that helps small and medium-sized businesses manage accounting, invoicing, payments, payroll and other financial tasks.
Australia and New Zealand provided Xero with its foundation, while the UK has developed into another substantial market. The company finished FY26 with 4.92 million customers globally, an impressive customer base for a company that began in New Zealand less than two decades ago.
Yet, Xero estimates its total addressable market at around 100 million small and medium-sized businesses worldwide.
The US could therefore be crucial to the next phase of growth for these ASX fintech shares. Xero had approximately 424,000 US customers at the end of FY26, leaving plenty of room to expand in one of management’s three most important markets.
The acquisition of US billing platform Melio has strengthened Xero’s US proposition by allowing businesses to manage outgoing payments directly through its platform. Management estimates the US small-business payments opportunity alone at US$29 billion.
Xero’s combination of accounting, payments and payroll gives customers more reasons to stay within its ecosystem. Its JAX artificial intelligence platform could provide another growth engine by automating financial tasks and helping customers make better decisions using their existing data.
There are risks, including intense US competition and the need to integrate Melio successfully.
Zip: US is only source of customer growth
Zip is a fintech company that provides buy now, pay later and digital payment services to consumers and merchants. It is also another ASX fintech share with a rapidly expanding US opportunity. The US is already its biggest source of growth, accounting for around two-thirds of revenue in FY26.
Total revenue increased 24.7%, including 37.3% growth in the US in Australian dollar terms. In US dollar terms, US revenue climbed 44.3%, compared with just 4.6% revenue growth in ANZ.
The US is also Zip’s only source of customer growth. US active customers increased 9.3% to 4.65 million, while ANZ active customers declined 8% to 1.88 million. For FY27, Zip expects US total transaction value growth of more than 30%.
Importantly, Zip isn’t simply growing revenue. Operating leverage is helping profits grow substantially faster. Cash gross profit rose 26.2% to $642.3 million in FY26, while cash operating profit jumped 57.9% to $268.9 million.
That combination of strong US growth and improving profitability makes Zip one of the ASX fintech shares I think investors should keep on their radar.
