Mercado Livre is winning Latin America’s ecommerce race. Winning it profitably is becoming more difficult. The company, known as Mercado Libre (Nasdaq: MELI) outside Brazil, is expected to report another quarter of exceptional expansion. The total value of goods sold through its platforms is forecast to rise by about 42% in dollar terms, including growth of roughly 38% in Brazil in local currency, according to BTG Pactual.
Yet profitability is moving in the opposite direction. The operating margin is expected to fall to 7.5% in the second quarter, about 4.6 percentage points below a year earlier. Mercado Livre is still capturing more business, but each additional sale is producing less operating profit. The squeeze is largely deliberate. Mercado Livre plans to invest R$ 57 billion, or about $11 billion, in Brazil in 2026, 50% more than last year. It intends to open 14 fulfillment centers, expanding its Brazilian network to 42 facilities, and hire 10,000 employees across logistics, technology and financial services.
That spending may be necessary. Amazon is expanding its local fulfillment capacity and faster-delivery services, while Singapore-based Shopee continues to build its logistics infrastructure and financial operations. Mercado Livre is no longer investing solely to enter new markets or capture customers. It is also paying to defend a position it has already won.
Market leaders are supposed to use scale to make growth cheaper. Mercado Livre is instead growing as quickly as a challenger while investing as though its leadership were under threat. That does not mean the strategy is misguided. A denser logistics network, stronger advertising revenue and the expansion of digital financial platform Mercado Pago could eventually allow earnings to rise faster than sales.
Investors, however, have been waiting for that operating leverage while earnings estimates have been revised lower. Mercado Livre trades at about 43 times estimated earnings for 2026 and 32 times those for 2027. Those valuations can be justified by exceptional growth, but only if today’s spending produces tomorrow’s margin recovery rather than merely preserving market share.
Mercado Livre is provisionally scheduled to report its second-quarter results on August 5. Management’s explanation of when its investments will begin to generate higher returns may matter more than another impressive sales figure. The company has already proved that it can outgrow its rivals. Its next test is showing that leadership is a source of operating leverage, rather than a bill that becomes larger every year.
