As global e-commerce continues to evolve, investors often weigh the massive scale of Amazon (NASDAQ:AMZN) against the high-growth potential of MercadoLibre (NASDAQ:MELI) to determine which is a better buy.
Amazon dominates North American retail and global cloud computing, while MercadoLibre has built a leading e-commerce and fintech ecosystem across Latin America. Both companies benefit from the digital transformation of commerce, but operate in different economic climates. This comparison examines their business strategies, recent financial performance, and current valuations to help you decide between them.
The case for Amazon
Amazon operates a vast global business in the retail stocks category, integrating consumer sales, logistics, and subscriptions. The company serves millions of customers through its retail stores and Prime membership, which offers millions of items with fast delivery. Beyond retail, its AWS segment provides essential cloud services to businesses and government agencies worldwide.
In FY 2025, revenue reached nearly $716.9 billion, representing a growth rate of approximately 12.4% over the previous year. Net income for the period was close to $77.7 billion, showing significant growth from prior years. The net margin, which shows how much of every dollar in revenue remains as profit after all expenses, reached approximately 10.8%.
The case for MercadoLibre
MercadoLibre operates a leading e-commerce and fintech ecosystem centered on its namesake marketplace and the Mercado Pago payments platform. The company serves 18 countries in Latin America, focusing on logistics and financial services for over 120 million unique buyers. Combining online shopping with digital banking creates a sticky environment for consumers in emerging markets.
In FY 2025, the company reported revenue of approximately $28.9 billion, a substantial 39.1% increase compared to the prior fiscal year. It achieved net income of roughly $2.0 billion during this period. The net margin for the year is close to 6.9%, reflecting the costs of expanding its physical logistics network and digital financial services.
Risk profile comparison
Amazon.com faces intense competition from large rivals such as Walmart in retail and Alphabet and Microsoft in the cloud computing sector. Regulatory scrutiny regarding data privacy and antitrust laws in international markets could lead to increased costs or operational changes. Additionally, the business remains vulnerable to cybersecurity threats and infrastructure interruptions that could compromise sensitive customer data.
MercadoLibre operates in a region characterized by macroeconomic and regulatory volatility, including high inflation and currency depreciation. It faces stiff competition from global players like Amazon and regional competitors that may use aggressive pricing to gain market share. The company also depends on third-party app stores operated by Alphabet and Apple, which could impose restrictive terms or higher commissions on its mobile applications.
Valuation comparison
Amazon.com trades at a lower Forward P/E based on earnings estimates, while MercadoLibre offers a more modest P/S ratio.
| Metric | Amazon.com | MercadoLibre | Sector Benchmark |
|---|---|---|---|
| Forward P/E | 30.3x | 41.5x | 29.6x |
| P/S ratio | 4.0x | 2.9x | n/a |

Which stock would I buy in 2026?
Both MercadoLibre and Amazon run large e-commerce operations, but their operations outside of e-commerce are very different. Amazon Web Services (AWS) are famously expensive, but that hasn’t stopped the highly profitable segment from growing by leaps and bounds.
MercadoLibre’s fintech segment is bringing Latin America into the 21st century with a slew of increasingly popular financial services. Unfortunately, helping small businesses accept payments isn’t as profitable as AWS.
MercadoLibre is a bit lacking in the profitability department, but a large addressable market seemingly eager to sign up for online banking services makes it an intriguing bet. Since I already own some Amazon stock, I’m inclined to choose MercadoLibre. That said, there’s no reason you can’t add shares of both to a portfolio.
