In this second part, we turn to the engine itself: its fully integrated business model, the competitive moats that protect it, the growth drivers that lie ahead along with a DCF model that capture Meli’s intrinsic value.

For long-term investors, the beauty of Mercado Libre is not just in its individual parts, but in how they combine to create a self-reinforcing flywheel.

The commerce marketplace attracts users, driving volume through the payments network.
The payments network generates data and trust, enabling a lucrative credit business.
And the entire system is underpinned by a logistics network that provides a superior experience, locking in customers and creating an insurmountable barrier for competitors.

This is the Meli ecosystem, a masterclass in vertical integration. Let’s dig deeper into this sixteenth edition of the Expanse Stocks’ Deep Dive Brief series:

Anatomy of the Meli Ecosystem

Meli has built what I’d argue is the most compelling e-commerce ecosystem, outside of China and the US, with a large TAM - still relatively underpenetrated (14% LATAM vs 26% in US and 30% in China) - combining a population of 500mm and GDP of $5 trillions. And the thing is, they didn’t just copy Amazon’s playbook as we saw in Part I, they adapted it for Latin America’s unique challenges and created something arguably more defensible.

At first glance, the company’s strategy is simple in: build a one-stop solution for commerce and financial services in a region where traditional infrastructure has consistently failed consumers. By controlling payments (Mercado Pago), logistics (Mercado Envios), advertising, and the marketplace itself, Meli addresses the two biggest pain points that have historically plagued Latin American e-commerce: unreliable payments and abysmal shipping.

Let’s take a closer look at how Meli reports its segments: Commerce and Fintech, although the business really operates across four interconnected pillars.

The Marketplace:

Sits at the core, connecting over 100 million active buyers with millions of sellers. GMV hit roughly $51 billion in 2024 and $60+ billion YTD, generated mainly through 3P sales. While Meli is strategically expanding its 1P operations (around 6% of GMV) to sharpen pricing and enter categories like groceries, the 3P model remains the bread-and-butter. Revenue comes from seller fees, which form the foundation of its commerce business.

The Fintech Platform:

This second leg of the Meli’s ecosystem has evolved from a simple payment solution into a comprehensive financial ecosystem. Mercado Pago processed nearly $197 billion in total payment volume in 2024 with 61 millions MAUs, spanning both on-platform and off-platform transactions. This includes merchant acquiring for millions of businesses, a digital wallet for consumers, and Mercado Crédito, a rapidly growing lending business that’s expanded from under $500 million in 2020 to $10 billion today.

The Logistics Network:

This is where Meli’s physical moat lives. Mercado Envíos ensures fast, reliable delivery in markets where infrastructure is poor. The company plans to expand to 22 fulfillment centers by 2025, creating what Daniel Wu describes as “largely unmonetized” infrastructure that drives user loyalty and seller stickiness. Services like “Meli Delivery Day”—fixed-day delivery for non-urgent orders—demonstrate how the network is being optimized for both cost efficiency and customer experience.

The Advertising Business:

This fourth leg remains the most underdeveloped lever with a 6.7% market share in Latam. Ad revenue still represents just 2% of Meli’s GMV, a fraction of Amazon’s penetration (closer to 10% of 3P GMV). As the ad-tech stack matures and seller adoption grows, this high-margin business should become a meaningful earnings driver.

There’s a powerful flywheel effect going on: pretty much all of the platform’s GMV flows through proprietary payment rails and ships through their own logistics network. So, consumption on the marketplace drives payments and then adoption of consumer credit and digital wallet drives consumption in the marketplace.

This creates multiple monetization opportunities on a single transaction: marketplace fees, payment processing fees, and potentially interest income from credit products. This is a deliberate strategy to own the entire value chain in markets where you simply can’t rely on third parties to deliver acceptable service levels and not just vertical integration for the sake of it.

The playbook mirrors what we’ve seen from the largest network-advantaged e-commerce players globally: attract users with shipping subsidies and membership rewards, reduce friction for sellers with intuitive tools, and make multihoming increasingly unattractive as fulfillment speeds improve and network effects compound. The reality is that this strategy works, and MELI is executing it better than anyone else in the region.
