Nu Holdings Crosses $1B Quarterly Net Income as AI and Latin Expansion Accelerate

A Milestone Quarter, Built on AI and Primary Banking

Nu Holdings reported its first-ever $1 billion quarterly net income, a symbolic threshold that validates its 13-year-old hypothesis of a branchless, technology-first bank. The company now serves 139 million customers, with activity rates hitting 83.5% and ARPAC reaching $17. As founder David Velez put it, “for the first time, we generated more than $1 billion in net income.” — David Velez-Osomo, Founder, Chief Executive Officer and Chairman · 2026-08-13 This milestone is not a discrete event but the compounding result of a strategy that has consistently prioritized primary banking relationships over short-term fee extraction. The ratio of customers using Nu as their primary account is a key driver of its credit quality and cross-sell potential.

The AI narrative is now central to Nu's operating model. The company’s foundation model, NuFormer, has been upgraded to a hybrid linear attention design and trained with Muon, the same optimizer used by frontier LLMs. According to Velez, “we recently advanced NuFormer to a hybrid linear attention design, the same architectural approach behind frontier models like Kimi K3 and Qwen3.5.” — David Velez-Osomo, Founder, Chief Executive Officer and Chairman · 2026-08-13 The model now powers underwriting, customer support, growth campaigns, and deposit pricing. A standout stat: AI agents handle over 60% of customer support conversations in Brazil, at or above human parity. The appointment of Velez to OpenAI’s board—acknowledged on the call—further signals that AI transformation is not a side experiment but a strategic pillar. This is a genuine company-unique theme, distinct from generic fintech buzzwords.

Expansion: Mexico, Croma, and the Super Core

Nu’s international story is accelerating. Earlier in August, Mexican regulators approved a full banking license, transforming Nu into the largest digital bank in Mexico with 16 million customers. Velez framed it as “Mexico is Brazil's playbook running faster.” — David Velez-Osomo, Founder, Chief Executive Officer and Chairman · 2026-08-13 The country’s digital payment adoption, aided by new central bank rules, mirrors Brazil’s PIX trajectory. Mexico already shows a higher ARPAC than Brazil at the same stage of penetration, and the full banking license unlocks deposit gathering, payroll direct deposits, and broader credit products—a classic product market fit expansion.

Meanwhile, in Brazil, Nu launched Croma, a subscription tier targeted at the “super core” segment—customers earning BRL 5,000–12,000. This is a deliberate move to deepen share of wallet in a profit pool larger than high income. As Velez noted, “Croma gives them a dedicated experience, enhanced credit offerings and a broader set of banking and lifestyle benefits.” — David Velez-Osomo, Founder, Chief Executive Officer and Chairman · 2026-08-13 The company already serves 3 out of 5 Brazilians in this bracket, so this is a monetization play on existing relationships rather than a costly customer acquisition war. Coupled with a growing SME business, Nu is systematically widening its Latin American moat.

Financial Discipline: Margin Expansion and Credit Quality

The quarter showcased an improving risk-adjusted net interest margin, which expanded to a record 12.4% from 9.5% a year ago. CFO Rob Livingston attributed the improvement to strong loan growth, seasonality, and disciplined underwriting, while also acknowledging the impact of Desenrola, a government debt renegotiation program, on cost of credit. He said, “the majority of the improvement in cost of credit came from the expected seasonal patterns we observed and disciplined underlying business performance rather than onetime items.” — Rob Livingston, Chief Financial Officer · 2026-08-13 The 15–90 day delinquency ratio improved 16bps to 4.8%, and the allowance coverage over NPL90+ stood at 244%, a level that signals resilience despite the 90+ NPL rising modestly due to seasonal migration. This is a contrast to the prior quarter’s cautious tone—the company is now confidently executing on intentional risk expansions that produce higher risk-adjusted returns.

The efficiency ratio of 19.5% remains one of the best in the industry, and management reaffirmed a ~20% full-year expectation, with long-term operating leverage intact. The transition from Guilherme Lago to Rob Livingston as CFO was smooth, and the new CFO has already absorbed the company’s ethos, emphasizing that the risk-adjusted margin is “in the same region as where we are today” for the foreseeable future.

That is what we have always meant by optimizing for the long term. It is why we can continue building for the next decade while delivering a quarter like this one.

What Changed and Why It Matters

Nu's trajectory has shifted from hypergrowth to a stage where technology, regulation, and customer behavior align. The first $1B quarter is not just a financial milestone; it validates the company’s ability to finance its own expansion while maintaining returns on equity above 30%. The global macro environment may pressure consumer credit, but Nu’s CEO is explicit: “we don't take a directional view necessarily on the economy. Our base assumption when we underwrite a loan is that the future will be worse than the past.” — David Velez-Osomo, Founder, Chief Executive Officer and Chairman · 2026-08-13 That conservative underwriting, combined with a customer base that increasingly treats Nu as their primary financial layer, provides a structural edge that peers lack.

From an investment perspective, the new strategic pivot—Croma, Mexico banking license, and AI at scale—is company-unique and supported by hard numbers. While the stock price data is not available in this context, the magnitude of the earnings beat and the upward revision in risk-adjusted margin expectations (>12% vs. prior 10.8% guide) should command attention. Nu is no longer just a regional disruptor; it is a compounding financial platform with a clear path to $100B+ in gross profit pools across Latin America. Thesuper core and SME segments add multiple expansion avenues. Whether the AI moat proves durable remains to be seen, but the evidence this quarter is strong.
