Nubank Q2 2026: $1B Quarter Inflated by Tax Break

Nubank reported Q2 2026 net income of $1.06B (first-ever >$1B), revenue of $5.9B (+39%), and a record 33% return on equity, driven by high operating leverage and AI-driven risk improvements. The author highlights that Nubank's effective tax rate fell to 14.17% from 27.56% a year earlier — reapplying last year’s tax rate would reduce Q2 net income to $896M — and notes an undisclosed $500M buyback. The newsletter also references Nubank’s in-house AI model “NuFormer” (claimed ~70% reduction in predicted risk) and Razorpay’s new Vulcan foundation model for payments (trained on ~4 billion payments), framing the quarter as both a fintech financial milestone and an example of AI-enabled operating leverage.

AI Accelerates in Finance; AIE NYC Announced

The AINews newsletter highlights the accelerating adoption of AI across financial services and announces AI in Finance as the mainstage theme for the second annual AIE NYC (October 2026), with early-bird tickets and speaker applications opening. The post summarizes a newly released finance track of talks from companies including FactSet, Nubank, Intuit, Kepler, Morgan Stanley, Fidelity, and others, emphasizing provenance, governance, auditable agent loops, simulation-driven evaluations, and supply-chain vetting of AI skills. It also reports several technical developments: OpenAI open-sourced a Codex Security CLI scanner, used GPT-5.6 Sol to optimize its serving stack (reported cost and efficiency gains), and launched expanded academic access for researchers. The newsletter covers recent agent security incidents, debates over coordinated pacing/governance, progress on open models like Kimi K3, and rapid tooling/benchmark advances for agents and harnesses.

Visa launches Stablecoin Platform

Visa has launched the Visa Stablecoin Platform, a managed-service offering that enables banks and fintechs to mint, move, and manage stablecoins using Visa’s rails. The platform will initially support Open USD, a token backed by a 140-member consortium that includes BlackRock, Stripe, and Coinbase. The market reacted the same day: Circle’s stock fell about 6%, Coinbase fell about 4.5%, and Visa’s stock rose about 2%. The newsletter also highlights unrelated fintech news in the same edition — Ramp unveiling a Free LLM Router and Nubank obtaining a bank licence in Brazil — but the central item is Visa’s entry into stablecoin infrastructure and the potential shift in who captures value in the stablecoins market.
