Nubank’s FY2025 Strength; Meta Tests Stablecoin Distribution
Nubank published its FY2025 results, which the newsletter characterizes as confirming the company’s combination of rapid growth and strong profitability, driven by a structural cost advantage versus incumbent Brazilian banks. The piece highlights Nubank’s low monthly cost-to-serve ($0.80) compared with roughly $5–$12 at legacy banks and frames the primary investor question as whether current valuations leave room for future returns given Latin American macro and credit-cycle risks. Separately, Meta is reported to be re-entering the stablecoin/payments space with a distribution-first approach (testing stablecoin payments across its apps) rather than issuing currency itself; the newsletter notes Stripe has been discussed as a potential launch partner for Meta’s stablecoin efforts.
Nubank’s FY2025 financials validate a profitable, low-cost digital banking model in a major emerging market, influencing investor views on fintech valuations and credit risk; Meta’s stablecoin strategy (and possible Stripe partnership) signals platform-level moves in payments/commerce rails that could reshape distribution and settlement models relevant to digital commerce and platform monetization.

MercadoLibre growth, card networks back stablecoins, Revolut AI desk
The newsletter analyzes three fintech developments: MercadoLibre’s multi-product “super app” flywheel across e-commerce, fintech, logistics, advertising and credit, arguing the company remains in early growth stages after its latest financials and a valuation gap versus the author’s $2,190 fair value estimate. It also reports that major card networks (Visa and Mastercard) are moving into stablecoins, signaling deeper payments-layer engagement with crypto-linked rails. Finally, Revolut reportedly built a trading desk powered by Claude AI in 30 minutes, illustrating rapid product iteration enabled by LLMs and raising questions about AI-driven product strategies in finance. The piece includes a bonus deep dive on Nubank and broader implications for finance, AI and payments infrastructure.
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.
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.
