Monzo is reported to be in preliminary discussions about a potential sale to Brazil’s Nubank, opening the possibility of one of the largest transactions yet involving a UK digital bank.
Sky News reported that Monzo has been approached by Nu Holdings, the New York-listed parent of Nubank, about a combination that could value the British lender at between £8bn and £10bn. The discussions are at an early stage, and there is no certainty that a transaction will be agreed.
Monzo has reportedly appointed Morgan Stanley and Qatalyst Partners to advise it. The outline structure and valuation of a possible deal remain under discussion, with neither company announcing a formal offer, timetable, or agreement.
Monzo declined to comment on the report. Nu Holdings told Sky News: “Nubank does not comment on rumours or speculation. We reaffirm our commitment to maintaining open, clear and timely communication regarding all significant business matters.”
A transaction would bring together digital banking businesses built at significant scale from different geographical bases. Monzo now says more than 16m personal and business customers use the bank, while Nubank reported 139m customers globally at the end of the second quarter of 2026 across Brazil, Mexico, and Colombia.
Monzo’s latest annual results showed revenue increasing by 39% to £1.7bn, with gross profit reaching £1bn and adjusted profit before tax of £172.6m. Customer deposits rose to £25.7bn as the bank expanded its lending, savings, subscriptions, business banking, and investment products.
Nubank has moved through a similar transition on a much larger scale. Its growth has increasingly been accompanied by rising revenue, credit balances, deposits, and profitability, giving the group greater capacity to consider expansion beyond its established Latin American markets.
An acquisition would give Nubank an immediate position in UK retail banking and an operating platform for further European growth without having to build a customer base from scratch. Monzo has already begun expanding on the continent, including a launch in Ireland and preparations for additional European markets.
The talks also create a new question around Monzo’s long-term route to the public markets. The bank has repeatedly been viewed as a potential major London flotation, while a US listing has also been discussed as an option. No formal timetable for an initial public offering has been announced.
That choice has broader implications for London. Policymakers and market operators have spent several years attempting to attract fast-growing technology and financial-services businesses to the UK equity market at a time when takeovers have removed a series of sizeable listed companies.
A sale of Monzo to an overseas banking group would not directly reduce the number of London-listed businesses because Monzo remains privately owned. It would, however, remove a prominent potential candidate from the pipeline if an acquisition were completed before a flotation.
The discussions are taking place as digital banks move into a more capital-intensive phase of development. Early growth was driven largely by current accounts, mobile applications, and customer acquisition. Larger operators are now expanding into lending, savings, investments, subscriptions, mortgages, business banking, and international markets.
That broadening of the model requires substantial spending on technology, compliance, financial-crime controls, customer service, risk management, and regulatory infrastructure. Monzo was fined £21m by the Financial Conduct Authority in 2025 over historic weaknesses in financial-crime controls, reinforcing the operational demands created by rapid expansion.
Greater scale can spread those costs across a larger customer base, one reason consolidation remains strategically attractive across financial services. Cross-border ownership can also bring access to technology, capital, and expertise that would be more expensive to build independently.
The strategic calculation for Monzo’s shareholders will therefore extend beyond the headline valuation. They must compare the certainty and structure of any proposed consideration with the potential value of remaining independent, raising further private funding, or pursuing a future listing.
Nubank would face its own questions around integration, regulation, and whether a UK acquisition would accelerate its global ambitions without distracting from growth in its core Latin American markets.
For now, those questions remain hypothetical. The companies are in preliminary discussions rather than an agreed transaction, and the reported £8bn–£10bn range is not a confirmed offer. The progress of the talks will nevertheless be watched closely across UK banking, fintech, and the capital markets because of Monzo’s size and its position among Britain’s most prominent privately owned technology businesses.
