MercadoLibre crossed $10 billion in quarterly revenue for the first time in Q2 2026 (the quarter ended June 30, reported in early August). The stock is 31% below its 52-week high. That is a wide gap for a company posting its best growth numbers since 2022.

Q2 2026 net revenue and financial income reached $10.17 billion, up 50% year over year, the fastest pace in four years, with Brazil continuing to show the strongest trends. The quarter before, net revenue and financial income were $8.85 billion, up 49% year over year, also the fastest pace in almost four years. Back-to-back acceleration at this scale is rare.

More Than an E-Commerce Company

The fintech operation is growing faster than the marketplace. The credit portfolio reached $16.4 billion in Q2, growing 75% year over year, with non-performing loans near historical lows at 7.0% total and 4.6% for credit cards. Fintech monthly active users reached 88 million, up 30% year over year. Assets under management grew 68% year over year, reaching $23 billion.

The advertising business may be the most underappreciated line. In Q2, MercadoLibre surpassed 10% share of the digital advertising market in Latin America for the first time, with net revenue growing 62% year over year on an FX-neutral basis. Its AI-powered ad tool reaches sellers on WhatsApp, analyzes campaigns in real time, and delivers fully automated recommendations with zero human intervention. One in three sellers who engage with it make a direct campaign change within the conversation. This is a high-margin revenue line that barely registers in most analyst models of the stock.

The Catalyst: November 4

MercadoLibre reports Q3 earnings on November 4, 2026. Analysts project Q3 revenue of approximately $10.35 billion, Q4 of $11.66 billion, and full-year revenue of $40.83 billion. The sequential revenue line implies continued acceleration into year-end, which would mark the company’s longest sustained growth streak in four years.

The average 12-month analyst price target is $2,264, with a high estimate of $2,800. Nineteen analysts recommend buying the stock. Zero suggest selling.

What Could Go Wrong

The margin compression is real. EBIT margin compressed to 6.7% in Q2, down 550 basis points year over year, due to heavy AI, logistics, and credit investments. Management has made clear it is optimizing for market share and long-term engagement, not near-term profitability. Investors who disagree have been voting with their sell orders. Currency risk in Brazil and Mexico adds uncertainty that FX-neutral growth numbers can obscure.

The company raised $1 billion in 10-year notes in September, adding to debt as it funds expansion. Higher leverage in a rising-rate environment is not a comfortable position even for a business growing this fast.

The Bottom Line

MercadoLibre is growing revenue at 50%, running one of the fastest-growing digital ad businesses in Latin America, and holding a $16 billion credit portfolio with NPLs near historical lows. Latin America represents one of the largest e-commerce growth opportunities in the world. E-commerce penetration is roughly half the level seen in the US, UK, and China, with no structural reason that gap should persist. The stock’s 31% discount to its high reflects margin anxiety, not a deteriorating business. With Q3 earnings on November 4 and analysts projecting another acceleration, the next six weeks will test whether the discount is justified.
