MercadoLibre Deepens AI-Powered Digital Banking as Fintech Drives 45% Revenue Surge

Artificial intelligence has stopped being a laboratory promise for MercadoLibre and become the visible engine of its business. Latin America's largest e-commerce and fintech platform is deepening its bet on AI-powered digital banking, integrating the technology into credit, customer service, and advertising. Whether you run a business in Houston, Cypress, Monterrey, or Bogotá, what is happening at MercadoLibre signals the direction digital commerce is taking across the region.

The news matters because it shows one of the region's largest companies treating AI not as an add-on but as core infrastructure. Below we break down exactly what the sources say, with no embellishment and no invented figures.

The AI Behind a 45% Revenue Surge

According to PYMNTS, MercadoLibre reported 45% year-over-year growth in net revenue during the fourth quarter. The same source notes that the advertising business grew 67% year over year in the same period, one of the company's fastest-expanding segments.

Chief Financial Officer Martin de los Santos tied that performance directly to investment in artificial intelligence. According to PYMNTS, de los Santos said: "Both of these are increasingly supported by the tangible impact of our investments in artificial intelligence." In other words, the executive attributes the lift in both revenue and advertising to the tangible impact of AI on the company's operations.

Mercado Pago and the Digital Banking Ambition

According to Yahoo Finance, MercadoLibre is expanding Mercado Pago from a payments platform into a broader financial services provider. The same source reports that the company integrates large language models and other AI tools to support credit underwriting and financial advisory services, with the stated goal of becoming the largest digital bank in Latin America.

Yahoo Finance frames this strategy as strengthening the links between the company's e-commerce marketplace and its financial services. The logic is direct: the more tightly shopping, payments, and credit are woven into one ecosystem, the greater the customer stickiness. A customer who shops, pays, and obtains credit on the same platform has fewer reasons to go elsewhere.

According to Yahoo Finance, MercadoLibre has 72 million active users. That user base is the ground on which the company builds its financial bet: every active user is a potential credit, payments, and advisory customer, and AI is the tool that lets the company serve at that scale without multiplying staff in the same proportion.

9 Million Inquiries, 87% Resolved Without Humans

The most concrete example of AI in action is the Mercado Pago assistant. According to PYMNTS, this AI assistant, launched in October, handled 9 million customer inquiries during the fourth quarter. Of that total, the same source reports that 87% were resolved without human support.

According to PYMNTS, the Mercado Pago assistant handles tasks such as transfers, bill payments, and general inquiries. Resolving nearly nine of every ten inquiries automatically, at a scale of millions, demonstrates that AI customer-service automation is no longer theoretical: it is a production operation sustaining the daily experience of millions of users.

AI Across the Operation: Sellers, Advertising, and Search

MercadoLibre's use of AI is not limited to banking. According to PYMNTS, the company uses AI-powered bidding algorithms and automated campaign tools for its advertising business, the same segment that grew 67% year over year. The same source reports that MercadoLibre also applies AI tools for merchant acquiring and identification.

According to PYMNTS, the company also has a Seller Assistant that creates videos, handles inquiries, and improves product listings. For a seller operating on the platform, this means that tasks that once required time and technical knowledge now have automated support.

On the buyer side, PYMNTS reports that MercadoLibre uses AI-enhanced search personalization for buyers in Argentina. Each of these pieces — advertising, merchant acquiring, seller assistance, and search personalization — points to the same pattern: AI is being embedded directly into commerce and finance, not as an optional layer but as part of the operating fabric.

Regional Scale and the Risks the Sources Do Not Hide

According to PYMNTS, MercadoLibre serves 18 countries in Latin America. That geographic breadth turns every AI improvement into a change that propagates across much of the region's digital commerce simultaneously.

But the growth is not without friction. According to Yahoo Finance, MercadoLibre's digital banking and credit strategy carries concrete risks: credit quality exposure, regulatory risk, and potential margin pressure stemming from the very investment in AI and product development. Using AI to decide who receives credit broadens reach, but it also amplifies the consequences of an assessment error. The sources present the bet clearly: high potential, accompanied by real risks the company must manage.

What This Means for Your Business

Here is the point that matters most for a business owner. What MercadoLibre does at regional scale previews how your customers will behave. When a platform with 72 million active users resolves 87% of its inquiries with AI and credits its growth to that same technology, it is teaching an entire region to expect conversational, immediate, AI-mediated answers.

The concrete problem: as AI becomes the layer that mediates between your customers and their buying decisions, businesses that AI does not recognize simply vanish from the conversation. When someone asks ChatGPT, Claude, Perplexity, or Google AI Overviews for the best provider of your service in your city, the business the AI names wins the customer. Most local businesses are invisible to these answer engines because their website lacks the structured signals AI needs to cite them with confidence.

That is where our AI Search Optimization (AEO) service comes in. The deliverable is direct: we audit your presence across ChatGPT, Claude, Perplexity, and Google AI Overviews, identify which signals are missing (schema markup, FAQ content, authoritative citations, consistent NAP data, and a llms.txt file), and hand you a prioritized plan so AI names you when a customer asks. While giants like MercadoLibre embed AI into every touchpoint, your job is to make sure that same AI knows your business exists.

"The giants are putting AI at the center of their business. If AI cannot name your business when a customer asks, it does not matter how good you are — for that conversation, you do not exist."
