MercadoLibre, Inc. and Nu Holdings Ltd. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between MercadoLibre, Inc. and Nu Holdings Ltd..

MercadoLibre, Inc. business model: MercadoLibre makes money in two ways. Commerce (Mercado Libre) charges sellers commissions on marketplace sales, collects shipping and fulfillment fees through Mercado Envios, sells advertising through Mercado Ads, and runs some first-party retail. Fintech (Mercado Pago) charges merchants fees on online and in-store payments (QR codes and Point card readers) and earns interest on consumer loans, merchant loans and credit cards. Mercado Pago also holds user deposits: assets under management reached $23 billion in Q2 2026. Payment processing grew out of the marketplace, but most of Mercado Pago's volume now comes from outside it.

Nu Holdings Ltd. business model: Nubank earns revenue mainly from interest on credit card balances, personal loans, payroll and secured loans, and from yield on the securities it buys with customer deposits. Fee and commission income adds interchange on card spending, late fees, and commissions from insurance, investments and marketplace sales. The model depends on acquiring customers cheaply (largely by word of mouth), serving them through an app at a low monthly cost, and then raising average revenue per active customer (ARPAC, about $15 a month in Q4 2025) by cross-selling credit, savings, investment and insurance products.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of MercadoLibre, Inc. stack up against those of Nu Holdings Ltd..

MercadoLibre, Inc. competitive advantage: MercadoLibre's main edge is that commerce, payments, credit and logistics all sit inside one company. It runs its own fulfillment centers, delivery fleet and Meli Air cargo flights, so it controls delivery speed in markets where postal services are unreliable. Mercado Pago gives it transaction data it uses to underwrite loans for people with thin credit files, and that credit in turn drives more marketplace spending. Rivals usually compete on just one front. Amazon competes in commerce, Nubank in banking, and Shopee and Temu on price.

Nu Holdings Ltd. competitive advantage: Nubank's edge is cost and scale. It runs without branches, reported a cost to serve below $1 per active customer per month and a record efficiency ratio of 19.9% in Q4 2025, and gains most new customers through referrals. Transaction and deposit data from more than 130 million customers feed its underwriting models, and that data advantage grows as more Brazilians use Nubank as their primary account.

Future prospects matter as much as current results. The growth strategies below explain how MercadoLibre, Inc. and Nu Holdings Ltd. each plan to expand from here.

MercadoLibre, Inc. growth strategy: Growth is coming from three places. First, buyer frequency: unique active buyers rose 26% to 89.3 million in Q2 2026 after Brazil's free-shipping threshold was lowered. Second, fintech depth: Mercado Pago monthly active users grew 30% to 88 million, quarterly payment volume topped $100 billion, and the credit book reached $16.4 billion. Third, higher-margin add-ons such as Mercado Ads and the Meli+ subscription.

Nu Holdings Ltd. growth strategy: Nubank is growing by deepening products for existing customers (secured and payroll loans, investments, insurance, small-business banking), scaling Mexico after its 2026 bank launch and Colombia, and entering the US through a sponsor bank while its national bank charter is finalized.
