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

Investors often debate whether to prioritize specialized niche leaders or regional giants. Choosing between Chewy (NYSE:CHWY) and MercadoLibre (NASDAQ:MELI) requires deciding which growth engine is a better buy today.

Chewy focuses on the essential pet care market in the United States, providing everything from food to healthcare services. MercadoLibre serves as the dominant e-commerce and fintech hub for Latin America. The comparison exists because both represent digital-first leaders in the consumer discretionary space that rely on high customer loyalty.

Chewy sells nearly 190,000 pet products and services to roughly 21.7 million active customers. In its latest annual report, filed for the fiscal year 2025, the company highlighted its position among retail stocks while expanding its physical clinic network. It maintains relationships with roughly 4,000 brands and supports nearly 20,000 veterinary practices via its PracticeHub platform. The Autoship program continues to drive recurring sales from loyal pet parents.

In FY 2025, revenue reached nearly $12.6 billion, representing growth of approximately 6.2% compared to the previous year. The net income for this period was roughly $222.8 million. This result represents a net margin, or the percentage of revenue remaining after all expenses, of approximately 1.8%. These figures show a business that is consistently profitable while continuing to expand its footprint in the pet healthcare space.

As of its February 2026 balance sheet, the debt-to-equity ratio was nearly 1.1x, which compares total debt to shareholder equity. The current ratio, which measures the ability to pay short-term bills with current assets, was roughly 0.9x. Free cash flow, or the cash remaining after capital investments, reached nearly $562.4 million. Note that stock-based compensation represented roughly 43.1% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.

MercadoLibre operates a massive ecosystem in Latin America, combining its e-commerce marketplace with its fintech division, Mercado Pago. The marketplace serves as a hub for third-party sellers, while the fintech arm provides digital accounts, payment processing, and credit services. According to its latest annual report, filed for the fiscal year 2025, the company also leverages a proprietary logistics network, Mercado Envios, to ensure fast delivery. This integrated approach, which includes the Meli+ loyalty program, helps drive high engagement among its 131 million unique buyers.
