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

Choosing between Coupang (NYSE:CPNG) and MercadoLibre (NASDAQ:MELI) is a choice between two regional e-commerce giants. Both dominate their respective markets, but which is the better buy for long-term investors today?

Coupang has mastered the densely populated South Korean market with its proprietary logistics network. Meanwhile, MercadoLibre operates an expansive ecosystem of retail and financial services across Latin America. While both companies leverage massive user bases, they face different macroeconomic environments and competitive pressures, making this a classic match-up between established regional leaders.

The case for Coupang

Coupang operates a massive e-commerce marketplace and owned-inventory business primarily in South Korea, though it is expanding into Taiwan. It differentiates itself through its WOW membership program, providing benefits like dawn delivery where items ordered at night arrive by morning. The company also manages a proprietary payment platform and operates Farfetch to support its global luxury goods expansion.

In FY 2025, revenue reached nearly $34.5 billion, representing a growth rate of approximately 14.1% over the prior year. This follows a trend of increasing revenue from close to $24.4 billion in 2023. The company reported net income of roughly $208.0 million for the year, resulting in a net margin of close to 0.6%, which measures how much of each dollar earned becomes profit.

As of its December 2025 balance sheet, the current ratio stands at approximately 1.0x, indicating the company has just enough short-term assets to cover its short-term liabilities. The debt-to-equity ratio, which compares total debt to shareholder equity, is nearly 1.0x. Free cash flow was close to $522.0 million. Note that stock-based compensation represented roughly 26.8% of operating cash flow, which inflates reported cash generation since it is a non-cash expense added back in the cash flow statement.

The case for MercadoLibre

MercadoLibre serves 18 countries with a dual-model ecosystem that includes a third-party marketplace and direct retail sales. The company has integrated its fintech division, Mercado Pago, which provides digital accounts and credit for retail stocks and consumers across the region. Logistics are handled by Mercado Envios, a network that ensures reliable delivery in geographies that often lack traditional infrastructure.

In FY 2025, revenue reached close to $28.9 billion, a substantial 39.1% increase compared to the previous fiscal year. This growth led to a net income of approximately $2.0 billion. The company achieved a net margin of roughly 6.9%, which provides a look at how much profit is generated from every dollar of sales.

Based on its December 2025 balance sheet, the current ratio is nearly 1.2x. The debt-to-equity ratio is approximately 1.7x, meaning the company uses more debt relative to its equity to fund operations. Free cash flow was very strong at close to $10.8 billion, representing the cash remaining after the business pays for its operations and capital expenditures.

Risk profile comparison

Coupang faces significant cybersecurity and data privacy risks following a November 2025 incident that affected 33 million accounts. The company also deals with intense competition from local rivals and global players like Amazon (NASDAQ:AMZN). Furthermore, it is subject to strict Korean fair trade and labor regulations, which include ongoing investigations and potential legal liabilities for its leadership.

MercadoLibre operates in volatile economic environments where inflation and currency devaluations are common in markets like Argentina. It competes against Amazon and new low-price Asian entrants, while its fintech division faces strict oversight regarding money laundering and banking laws. The company also manages credit risk through its lending business, where inaccurate models could result in higher default rates among its borrowers.

Valuation comparison

While Coupang is cheaper based on its P/S ratio, both companies trade at a significant premium regarding their Forward P/E, which compares stock price to future earnings estimates.

Which stock would I buy in 2026?

I'd go with MercadoLibre. The breadth of what it has built across e-commerce, fintech, and logistics simultaneously across an entire continent puts it in a different category from Coupang, even accounting for Coupang's dominance in South Korea.

That is not to dismiss Coupang, though. Its core commerce business continues to grow, customer loyalty is strong, and its acquisition of Farfetch adds a luxury fashion dimension that broadens its appeal. The lingering effects of a customer data breach and currency headwinds from a weaker South Korean won are manageable headwinds rather than structural problems.

MercadoLibre, meanwhile, just crossed $10 billion in quarterly revenue for the first time, growing at the fastest pace in four years. Commerce and fintech are accelerating simultaneously across Brazil, Mexico, and Argentina, markets where digital adoption still has an enormous runway ahead. For patient investors, the size of MercadoLibre's opportunity and the pace at which it keeps capturing it make it the stronger pick right now.
