Alibaba Group Holding LtdAlibaba's rival MercadoLibre faces margin pressure from 1P expansion, potentially benefiting Alibaba as a stronger competitor
MercadoLibre's aggressive scaling of its first-party business is creating structural profitability pressures that could delay margin recovery. The company's 1P gross merchandise volume surged 69% year over year on a foreign exchange-neutral basis in the first quarter of 2026, far outpacing overall marketplace growth and driving a 300-basis-point contraction in gross margin. While the strategy strengthens assortment and pricing in categories like consumer electronics, the inventory-led model requires greater capital intensity, with logistics and warehousing costs rising alongside volume. MercadoLibre appears willing to prioritize market-share gains over near-term earnings, and as 1P continues to absorb a growing share of corporate costs, the path to margin normalization is expected to remain challenging. The company faces stiff competition from Amazon and Alibaba, both of which have expanded similar capabilities, and its simultaneous ramp-up of fintech, free shipping, and logistics spend could keep profitability under pressure for longer.
