Brazil’s Nubank, Itaú Lead Latin America AI Bank Ranking
Latin America · Business
Key Facts
—Who ranks them. Evident Insights, an independent research firm, published the 2026 Evident AI Index for Banks – LATAM.
—The method. It scores the 20 largest banks on 60-plus indicators across Talent, Innovation, Leadership, and Transparency using only public data.
—The top four. All four are Brazilian: Nubank, Itaú Unibanco, Banco Bradesco, and Banco do Brasil.
—Investment reality. Over 70% of Latin American financial entities are already investing in artificial intelligence.
—What is still rare. Only 8% of large LATAM banks have advanced generative AI in production.
When a ranking names the region’s smartest banks in artificial intelligence, the method matters more than the medal. The 2026 Evident AI Index for Banks – LATAM, published by independent research firm Evident Insights, scores the 20 largest banks across four pillars using only publicly available data, then hands the top two spots to Brazilian heavyweights Nubank and Itaú Unibanco.
How Evident Insights Actually Scores the Banks
Evident Insights builds its index from millions of public data points: patents, research papers, earnings-call transcripts, and strategy documents. No bank fills out a questionnaire, and no one pays to be included.
The firm evaluates each bank on 60-plus indicators grouped into four pillars: Talent (who they hire and how they train), Innovation (patents and research output), Leadership (what executives say on the record), and Transparency (how openly they disclose their AI work). The result is a single maturity score that rewards substance over press releases.
What Nubank's Artificial Intelligence Work Changes for a Customer
Nubank, the São Paulo-based digital bank with over 100 million customers across Brazil, Mexico, and Colombia, now runs a proprietary model called NuFormer for real-time credit decisions. In practice, that means a freelancer in Mexico City who applies for a Nu credit card gets an approval or decline in seconds, not days, based on data patterns a traditional scorecard would miss.
The bank says nearly 100% of its employees use AI tools daily, and it is building what it calls a “bank native to AI.” For an ordinary user, that translates to fewer generic chatbot loops and more cases where the app already knows why you are calling before you finish typing.

Itaú Unibanco: 500 Use Cases, One App
Itaú Unibanco, Latin America’s largest bank by assets, has deployed over 500 internal artificial intelligence use cases. The ones customers actually feel are embedded in everyday channels: Pix payments initiated via WhatsApp, investment recommendations inside the Itaú app, and fraud checks that run silently behind a card swipe.
The bank’s focus is scaling AI across both customer-facing products and back-office productivity. For a small-business owner in São Paulo, that means faster loan pre-approvals and fewer documents to upload, because the system already pulls and verifies tax and invoice data from public and private registries.
Why Brazil Sweeps the Board
Brazilian banks account for 35% of the 20 institutions in the index but produced 49% of all AI use cases with reported outcomes over the past two years. The country’s mature instant-payment rails (Pix), high smartphone penetration, and a regulatory sandbox at the Central Bank of Brazil give its lenders a head start that peers in Mexico, Chile, or Colombia have yet to match.
Globally, about 85% of financial AI use cases still sit in back-office tasks: data processing, compliance screening, operational optimization. In early 2026, roughly 30% of new global use cases shifted toward agentic AI, autonomous systems that can act without a human clicking “approve.” Latin America’s leaders are watching that shift closely, but for now the customer-facing wins are concentrated in credit and payments.
The Investment Landscape: Big Spending, Early Stages
More than 70% of Latin American financial entities are already investing in artificial intelligence, and 61% of executives confirm they are increasing that investment. The returns are coming quickly: 77% of firms reported a positive return on investment within the first year of a generative AI project.
Yet the gap between intention and production remains wide. Only 8% of large Latin American banks have advanced generative AI in production, while 58% have not started any generative AI project at all.
For expat investors and fintech entrepreneurs, this signals a market still rich with opportunity but demanding patience and local partnerships.
What This Means for Expats, Investors, and Tourists
For a foreigner living in or moving to Latin America, a bank’s AI maturity directly shapes daily financial life. Faster credit approvals mean a newly arrived professional in Mexico City can get a local credit card without a years-long local credit history, because Nubank’s NuFormer model reads alternative data patterns.
For investors, the Brazilian sweep of the top four spots is a signal of where scalable fintech returns are most likely. The combination of Pix, a forward-leaning central bank, and fierce competition among digital-first and legacy lenders creates a laboratory for AI-driven products that often reach consumers before similar tools appear in Europe or the United States.
Tourists benefit more subtly. AI-powered fraud detection running behind every card swipe means fewer blocked transactions and fewer embarrassing declines at a Rio de Janeiro restaurant.
Itaú’s WhatsApp-based Pix payments also let visitors pay instantly without downloading a local banking app, a quiet convenience built on machine-learning infrastructure.
Frequently Asked Questions
Which Latin American bank ranks first for artificial intelligence in 2026?
Nubank ranks first in the 2026 Evident AI Index for Banks – LATAM, followed by Itaú Unibanco in second place. The index, compiled by independent research firm Evident Insights, evaluates the 20 largest banks in the region using more than 60 publicly available indicators across talent, innovation, leadership, and transparency.
What does Nubank use artificial intelligence for?
Nubank uses its proprietary NuFormer model for credit scoring and loan decisions in Brazil and Mexico, and has integrated AI tools across nearly all employee workflows. The bank describes its strategy as building a "bank native to AI," meaning artificial intelligence is embedded in customer-facing features like instant credit approvals as well as internal operations.
Why are Brazilian banks ahead in AI adoption?
Brazil benefits from a large digital-banking market, the Pix instant-payment system, a supportive regulatory sandbox at the Central Bank of Brazil, and heavy investment in AI talent and patents. These factors give Brazilian lenders a structural advantage that peers in Mexico, Chile, or Colombia have not yet replicated, which is why all four top spots in the 2026 Evident AI Index belong to Brazilian institutions.
