MercadoLibre’s Post-Founder Era Opens at Full Sprint

MercadoLibre began its first full quarter without founder Marcos Galperín as chief executive by posting its fastest revenue growth in almost four years — and then watching its shares fall, because all that growth came at the cost of profit margin.

Latin America’s most valuable company changed hands at the top on January 1, 2026, when Ariel Szarfsztejn — an insider since 2017 who had run the commerce business — succeeded Marcos Galperín, the founder who built MercadoLibre over a quarter of a century. Galperín moved up to executive chairman. The handover was announced back in May 2025, so it was no surprise; the real test was always going to be the numbers that followed.

Those numbers arrived on May 7 and they were emphatic. Net revenues and financial income reached US$8,845 million in the first quarter, up 49% year-on-year — the company’s quickest expansion since 2022. Gross merchandise volume climbed 42% to US$19.0 billion, and the payments arm, Mercado Pago, processed US$87.2 billion in total payment volume, a 50% jump. By almost every top-line measure, the post-founder era opened at a sprint.

The engine is fintech, not just the marketplace

Increasingly, MercadoLibre is a bank wrapped around a shopping site. Mercado Pago ended the quarter with 83 million monthly active users, up 29%, while assets under management grew 77% to nearly US$20 billion. The credit book — the riskier, higher-margin frontier — expanded 87% to US$14.6 billion, and the credit-card portfolio more than doubled, rising 104% to US$6.6 billion, with 2.7 million new cards issued in the quarter alone.

That credit machine is what lets MercadoLibre keep buyers and sellers inside its ecosystem, and it is the clearest expression of the strategy Szarfsztejn has inherited: use financial services to deepen loyalty, then monetize the resulting volume across advertising, logistics and lending.

Growth bought with margin

The catch is profitability. Income from operations actually fell 20% to US$611 million, and the operating margin slipped to 6.9%. Net income landed at US$417 million. Earnings per share of US$8.23 came in below the roughly US$9.37 that analysts had penciled in, and investors reacted sharply: the stock fell about 11% the day after the report.

None of that reflects a business in trouble. It reflects a deliberate decision to plow the gains from scale back into free shipping, consumer credit and artificial-intelligence tooling rather than let them drop to the bottom line. It is the same playbook that built the company — spend to take share while rivals hesitate — now being run by a new hand.

Why it matters for Latin America

MercadoLibre is the region’s e-commerce and fintech benchmark, and the competitive backdrop is hardening. Amazon continues to invest across Mexico and Brazil, while Asian challengers Shopee and Temu chase the same price-sensitive shoppers. Banking incumbents and Nubank are fighting for the same wallets Mercado Pago wants to own.

The strategic logic of trading margin for growth makes sense only if the share gains prove durable and the credit book stays healthy as it scales. The first quarter under new management suggests the company has not lost its appetite for that bet. Whether the market keeps rewarding it — after years of treating MercadoLibre as a rare profitable growth story — is the tension that will define Szarfsztejn’s tenure.
