Better International E-Commerce Stock: MercadoLibre vs. Sea Limited

Comparing MercadoLibre (NASDAQ: MELI) with Sea Limited (NYSE: SE) may be a difficult feat for investors. Both companies lead e-commerce in their respective regions and have also built successful fintech businesses around serving customers in the developing world.

Additionally, both are profitable companies with fast-growing revenue, making it likely they will succeed over time.

Still, if choosing one of these stocks, investors will probably need to take a deeper dive into each enterprise to determine which consumer discretionary stock is likely to deliver higher returns.

The case for MercadoLibre

Admittedly, MercadoLibre holds the edge when it comes to focus. For one, it operates exclusively in Latin America. This may look like a disadvantage given the political and economic turmoil that often makes doing business in the region chaotic.

Fortunately, the company has turned Latin America's challenges into competitive advantages. When cash-based customers could not buy on its site, it formed Mercado Pago to bring these shoppers into the digital financial world. With that start, it eventually emerged as a leading fintech company in Latin America.

Furthermore, logistical challenges in its region prompted it to launch Mercado Envios, improving the fulfillment and shipping options available in the region.

These, along with its other enterprises, work both separately and together to spur the company's growth. Amid those synergies, it generated $19 billion in revenue in the first half of 2026, a 50% increase from the year-ago period and a growth rate that has made MercadoLibre hard to ignore.

Still, other parts of the income statement point to issues. During the same period, net income was $883 million, down 13% over the previous year. Increased e-commerce competition led to lower margins, and rising loan volumes forced it to increase the provision for doubtful accounts to cover loans that went bad.

Nonetheless, taking a hit now in these businesses may spark long-term growth, as its competitive moves should help it gain market share. Moreover, while its 53 P/E ratio may sound high, Amazon often traded at higher P/E ratios in its growth years. That could bode well for MercadoLibre as it continues to grow.

Why investors might choose Sea Limited

Sea Limited is the MercadoLibre of Southeast Asia in many respects. Its Shopee business has become the leading e-commerce company in Southeast Asia, and like Amazon and MercadoLibre before it, Sea Limited has invested heavily in logistics to solidify that position.

Additionally, its Monee segment helps cash-based customers buy on Shopee. Like Mercado Pago, Sea Limited has also emerged as a regional fintech leader in its own right.

However, it differs from its peers in that it started as the online gaming company Garena and gained attention with its mobile game, Free Fire. It was only when founder Forrest Li saw the e-commerce opportunity that the company diversified.

Still, that makes it a less cohesive business than MercadoLibre. That lack of connection affected Sea Limited a few years ago, when it made ill-fated attempts to establish e-commerce ventures outside Southeast Asia. Most of those failed quickly, though it continues to operate in Brazil.

Fortunately, after this misstep, Sea Limited followed its peers' lead and invested more heavily in logistics in its home region. This move helped spark a recovery. Consequently, in the first half of 2026, revenue increased by 47% yearly to $14.9 billion. Its net income for that time frame, $896 million, rose by just 9% from the year-ago level. Investments in its business and fast-rising credit losses slowed profit growth.

Nonetheless, like with MercadoLibre, those moves amount to investments in its business that should pay off in the long run. Also, Sea Limited has a P/E ratio of 44, making it slightly cheaper than MercadoLibre and possibly more attractive to some investors.

MercadoLibre or Sea Limited?

Investors are unlikely to go wrong with either company. Still, if I have to choose one, I give the slight edge to MercadoLibre.

Both companies operate leading e-commerce and fintech businesses in their regions, and with opportunities for growth, revenues should continue to rise rapidly. That should help MercadoLibre and Sea Limited beat the market over time.

However, MercadoLibre started as an e-commerce enterprise and later launched other businesses to enhance its e-commerce operations. It operates enterprises that can work together or separately to capitalize on opportunities, making it a comparatively more cohesive enterprise.

In comparison, while all three of Sea's businesses performed well recently, Garena's performance is often not on par with Shopee's and Monee's, and it offers few opportunities for synergies. Amid that difference, it could make sense for investors to pay a slight premium and choose MercadoLibre.
