Nubank Adds 10m Mexican Customers In First Year, Confirming LatAm Expansion Roadmap

Nubank confirmed in its quarterly disclosure that the Mexican operation has added 10 million customers since the formal banking-licence operational launch one year ago, in a milestone that comfortably ahead of the company's internal twelve-month target and confirms the São Paulo-headquartered digital-banking group's pan-Latin-American expansion roadmap is delivering on schedule.

The Mexican customer-acquisition pace — averaging roughly 830,000 net new customers per month across the year — represents the fastest country-launch trajectory the company has run, comfortably exceeding the equivalent profile from the original Brazilian launch and the more recent Colombian expansion. The credit-product attach rate has firmed faster than expected: roughly 30% of Mexican customers now hold an active credit product, against an internal underwriting model that had assumed reaching 30% would take eighteen months rather than twelve.

The unit-economics profile has materially improved across the cohort. Customer-acquisition costs in Mexico have declined as the brand has scaled and the referral-driven acquisition channel has compounded; net interest income per active customer has firmed steadily across the four quarters; and the credit-loss-rate experience has tracked at the conservative end of the company's underwriting model, with the better-than-expected loss-rate evidence substantially supporting the case for accelerated credit-product expansion through the next phase.

Strategically, the Mexican success substantially strengthens the case for the wider Latin American expansion now in active planning. Argentina is the most-discussed next-launch market, with regulatory engagement progressing through the relevant licence-application gates over the past several quarters; Chile and Peru are both on the strategic-planning horizon for 2027 launches. Beyond the regional-Latin-American focus, the company's longer-term US-market entry — telegraphed but not formally confirmed — remains a more open question that will likely be addressed at the full investor-day cycle later in the year.

For investors, the Mexican milestone confirms the case that Nubank's product-and-acquisition model travels effectively across Latin American markets without requiring substantial structural redesign for each launch. The implication for the consensus model is that the regional addressable-market sizing — which has historically been the principal valuation question for the company — is now meaningfully easier to underwrite than it was twelve months ago. The Mexican performance, more than any other single data point, has crystallised the case that the company is now genuinely operating as a pan-regional digital-banking group rather than a Brazilian bank with international ambitions.
