MercadoLibre, Inc.MELI posted impressive second-quarter 2026 net revenue and financial income of $10.2 billion, representing a 50% year-over-year increase. However, operating income fell 17% to $683 million, pulling operating margin down 550 basis points to 6.7%, although it contracted only 20 basis points sequentially. Net income margin also contracted 310 basis points year over year to 4.6%. The margin pressure reflects MercadoLibre’s deliberate decision to prioritize investments in engagement, growth and scale over near-term profitability.
The clearest test of whether that sacrifice is paying off comes from Brazil. A year after MercadoLibre lowered its free-shipping threshold, conversion remained 1.1 percentage points higher year over year. New buyer cohorts are purchasing more items across more categories and showing higher retention. The economics of free shipping are also improving as scale and logistics efficiencies make more lower-priced shipments profitable.Â
MercadoLibre has extended this strategy through PIX discounts for buyers and lower take rates for sellers in selected categories. While these actions weigh on near-term profitability, they improved price competitiveness and helped active sellers grow 29% year over year. Meanwhile, items sold per unique buyer increased 14%, including 19% growth in Brazil.Â
The payoff is also visible in broader commerce activity. Gross merchandise volume increased 36% year over year on an FX-neutral basis, while items sold advanced 45%. Unique active buyers reached 89.3 million, up 26%, with Brazil showing the fastest growth as the impact of the lower free-shipping threshold continued to compound.
Deeper engagement carries economic value. Users who participate in both MercadoLibre’s marketplace and Mercado Pago generate more GMV, purchase across more categories and are substantially more profitable than users of either service alone. Management said contribution profit per ecosystemic user is multiples of that generated by marketplace-only and fintech-only users combined.Â
For now, the growth-for-margin trade-off is producing measurable behavioral gains. Higher conversion, purchasing frequency, retention and seller participation indicate that MercadoLibre’s investments are deepening engagement, while improving shipping economics provide early evidence that some of the initial margin pressure can ease as scale builds.
