Chewy vs. MercadoLibre: Which E-Commerce Stock Is a Better Buy in 2026?

The article compares Chewy, a U.S. online pet retailer, and MercadoLibre, a Latin American e-commerce and fintech platform. MercadoLibre shows stronger revenue growth at 39.1% in 2025 versus Chewy's 6.2%, but both face challenges: Chewy has thin margins and single-digit growth, while MercadoLibre sacrifices profitability for expansion and faces credit risks. The author favors MercadoLibre as a long-term buy despite volatility, while viewing Chewy as steadier but requiring veterinary acquisitions to prove value.
