Is MELI a Buy? What to Consider in 2026

Last updated June 2026

Short answer

There is no universal answer to whether MELI is a buy; it depends on your thesis, time horizon, and what you already own. Below is the case for MercadoLibre, the main risks to weigh, where the stock trades, and a framework to decide for yourself. This is informational, not a recommendation, and Walnut is not an investment adviser.

MercadoLibre is the largest e-commerce and fintech company in Latin America. The company operates across three main lines. Mercado Libre Marketplace is the dominant e-commerce platform in Latin America, present in 18 countries with the largest scale in Brazil, Mexico, and Argentina. Mercado Pago is the largest fintech platform in Latin America, originally built as a payments solution for the marketplace and now expanded into a full digital wallet, credit, and asset management offering. Mercado Envios provides logistics infrastructure for marketplace sellers. The combination of e-commerce, payments, and logistics creates network effects that are difficult for any single-purpose competitor to match. Founded in 1999 by Marcos Galperin in Argentina, headquartered in Montevideo, Uruguay (with operational headquarters spread across the region). Marcos Galperin is still CEO.

The case for MercadoLibre

1. Brazil and Mexico growth.

Brazil and Mexico together represent the majority of revenue and growth. E-commerce penetration in Latin America remains low compared to developed markets, providing long-duration growth runway. MercadoLibre continues to take share from offline retail.

2. Mercado Pago expansion beyond marketplace.

Mercado Pago has expanded beyond facilitating marketplace transactions to become a full digital wallet, credit provider, and asset management platform. Off-marketplace payment volume is growing fast and is now a significant share of total. Credit and investment products carry higher margins.

3. Logistics infrastructure as moat.

Mercado Envios's logistics network (fulfillment centers, last-mile delivery, cross-docking) is a structural advantage. New competitors would need to replicate decades of infrastructure investment to compete on delivery speed and reliability.

4. Argentina exposure and currency volatility.

Argentina has historically been a large revenue contributor but is volatile due to currency devaluations and inflation. MercadoLibre reports financials in USD but the underlying Argentinean operations face structural macro challenges.

The risks to weigh

Currency volatility (especially Argentina) affects reported financials. Amazon's expansion in Mexico and Brazil intensifies competition. Regulatory changes in fintech (particularly around credit) can affect Mercado Pago.

Valuation context (as of early 2026)

Revenue (TTM): ~$20 billion
Operating margin: ~12% (improving)
Net income (TTM): ~$2 billion
EPS (TTM): ~$40
P/E (TTM): ~50x
Price to sales: ~5x
Dividend yield: None
Free cash flow: Improving as marketplace and fintech mature
Geographic exposure: ~55% Brazil, ~25% Mexico, ~15% Argentina, balance other

MercadoLibre's premium valuation reflects its dominant position in Latin American e-commerce and fintech, the long-duration growth runway from low e-commerce penetration, and the strength of the combined marketplace-payments-logistics platform.

How to decide for yourself

Rather than asking whether MELI is a buy in the abstract, it tends to help to answer four questions:

Thesis: do you believe the case above, and is it still true today?
Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
Overlap: check whether you already hold MELI indirectly through an index or sector ETF before adding more.

For the full picture, see the MELI stock guide (what the company does, the ETFs that hold it, similar stocks, and the themes it fits). In Walnut you can ask its AI about MELI against your real portfolio and see your actual exposure before deciding.
