Nubank Q1 2026: First $5 Billion Revenue Quarter, 135 Million Customers
Nu Holdings (NYSE: NU), the parent company of Nubank , reported its strongest quarter on record on May 14, 2026, posting revenue of $4.97 billion under accounting standards and $5.32 billion on a managerial basis, the first time the company has crossed the $5 billion threshold in a single quarter. Net income reached $871 million , up 41% year over year, while the customer base crossed 135.2 million globally, adding roughly 4 million users in the first three months of 2026 alone.[1] Record Scale Across Every Metric The quarter was notable not for any single data point but for the breadth of the acceleration. Nubank's total credit portfolio expanded 40% year over year to $37.2 billion , driven by a 36% increase in credit card balances, 53% growth in unsecured lending, and 38% growth in secured lending. Total deposits rose 22% to $42.4 billion , funded at 88% of interbank rates, a structural cost advantage that contributes directly to the company's industry leading efficiency ratio of 17.6% , improved from 19.9% in the prior quarter.[1][2] Return on equity held at 29% , up from 27% in the same quarter a year earlier, and the monthly activity rate reached 83%, reflecting a customer base that is deepening its engagement rather than merely growing in number. Monthly average revenue per active customer approached $16 , a 23% year over year increase that signals meaningful monetization progress beyond basic accounts.[2] | Metric | Q1 2026 | YoY Change | | | | | | Revenue (accounting) | $4.97B | +53% | | Revenue (managerial) | $5.32B | +58% | | Net income | $871M | +41% | | Total customers | 135.2M | +17% | | Total credit portfolio | $37.2B | +40% | | Total deposits | $42.4B | +22% | | Return on equity | 29% | +200 bps | | Efficiency ratio | 17.6% | 230 bps | | ARPAC (monthly) | ~$16 | +23% | The Americas Footprint Takes Shape The geographic story of Q1 2026 is the clearest articulation of Nubank's full Americas thesis. Brazil anchors the platform with more than 115 million customers , making Nubank the country's largest private financial institution, with roughly 7% of a domestic addressable profit pool exceeding $100 billion annually.[1] Mexico crossed a strategic threshold in Q1 by achieving break even, doing so faster than Brazil reached the same milestone. The Mexican customer base now exceeds 15 million , a roughly seven fold increase in four years, and the unit's monthly average revenue per active customer has nearly doubled over that period. Nubank described Mexico as now holding the position of the third largest financial institution in the country by customer count.[1] Colombia continued its expansion trajectory, approaching 5 million customers and contributing another quarter of net additions. The US market remains a deliberate long term project: in January 2026, Nubank received conditional approval from the Office of the Comptroller of the Currency (OCC) to establish a national bank under the name Nubank N.A., a milestone that opens the pathway to accepting deposits, extending credit, and eventually offering digital assets to US consumers. Management has committed to keeping US investment below 100 basis points of the consolidated efficiency ratio annually through 2027.[2][3] | Geography | Customers | Status | | | | | | Brazil | 115M+ | Largest private financial institution | | Mexico | 15M+ | Break even achieved Q1 2026 | | Colombia | ~5M | Expanding; net additions each quarter | | United States | Pre launch | OCC conditional charter approved Jan 2026 | This Americas build out is unfolding alongside, not despite, the accelerating global neobank market. A Simon Kucher study published in March 2026 found that digital first banks now serve more than 1.4 billion accounts worldwide , growing at a compound annual rate of approximately 13%, with revenue per customer up 30% from 2021 to 2025.[4] Nubank, with 135 million customers and an efficiency ratio well below 20%, sits at the profitable frontier of that wave, positioned similarly to how Revolut is targeting Mexico and Monzo has signaled US ambitions, though at a scale neither has approached in the Americas. AI as Operating Infrastructure David Velez, founder and CEO of Nubank, framed the company's artificial intelligence investment not as a feature set but as a foundational rebuild: "Our AI transformation is a core priority of Nu. We are not adding AI to banking, we are rebuilding banking around AI. NuFormer, our proprietary set of foundation models, is in production today for credit card in Brazil and Mexico, and for unsecured lending in Brazil. Our AI Private Banker functionalities already serve more than 15 million monthly active users. These capabilities have been a meaningful driver of the significant expansion of our credit portfolio over the last twelve months, enabling us to grow limits with resilience, not just speed." The NuFormer foundation model is pricing and approving every personal loan request individually in under a second, drawing on first party behavioral data from 135 million transacting customers. Engineering throughput increased 50% year over year , testing cycles ran 90% faster , and weekly token consumption reached nearly ten times the level recorded at the start of 2026, all attributed to AI native tooling embedded across the development workflow.[1] Cristina Junqueira , co founder of Nubank, captured the trajectory from a different angle in a post following the results: "We understood, from early on, that business profitability was a natural consequence of investing in the single best customer service, experience, and products. And here we are: our most profitable quarter ever, with Nu Mexico reaching breakeven even faster than Brazil, proving that our model is scalable and adaptable."
