3. AI: 56,000 sellers used AI advisors to manage advertising, nearly quadrupling in three months; the AI shopping agent has been opened on a small scale in Brazil, Mexico, and Argentina, with preliminary but encouraging test results.

Mercado Libre's brand marketing and channel signals center on advertising products, off-platform media, and user operations.

1. Advertising and brand marketing: Mercado Ads revenue rose 58% year over year, with strong demand in Brazil; beyond on-platform retail media, Mercado Libre also partners with streaming services such as Netflix and social platforms to extend commercial media from off-platform exposure to on-platform conversion, creating a full-funnel closed loop. The brand advertising product Engage+ uses AI to analyze purchase data, predict the consumers most likely to purchase in a brand category, and then direct budget toward those consumers; it has launched across six sites.

2. Users and channels: Unique buyers exceeded 93.9 million, up 22% year over year, with 9.2 items purchased per buyer; registered users in Brazil's loyalty program grew at an accelerating pace; in September, Argentina expanded MELI+ free shipping coverage for low-priced items, with repeat purchase frequency hitting a new high.

3. Products and trends: Mercado Libre's proprietary AI shopping agent is being tested on a small scale in Brazil, Mexico, and Argentina; Mercado Libre has not opened its inventory to external platforms for now and aims to complete the agentic shopping experience within its own app.

Mercado Libre's Q3 update gave sellers information across three areas: growth markets, fulfillment support, and AI operating tools.

1. Growth markets: In Brazil, item sales rose 36% year over year and units rose 45%; in Mexico, GMV rose 21% and units rose 25%; in Argentina, GMV rose 40% and units rose 19%; in other markets, units rose 44% and GMV rose 43%. In Brazil, shipped units grew more than 40% over the past five quarters, and in Mexico same-day delivery has been achieved in more than 37 core cities.

2. Fulfillment opportunities: Before peak season, Latin American fulfillment space increased nearly 20% quarter over quarter; the Dongguan China warehouse covers 60,000 square meters, has total capacity of over 5 million items, and handles a peak daily outbound volume of 500,000 items, with automated conveyance, sorting, and multi-line packing verification. These capabilities help Chinese sellers with inventory preparation and outbound operations.

3. Operating tools: 56,000 sellers used AI advisors to manage advertising, nearly quadrupling in three months; the affiliate marketing program has 12 million members. Risks and limitations include that Mercado Libre has not opened product inventory to external platforms such as ChatGPT, and seller traffic remains concentrated in Mercado Libre's own app.

The implications for factories lie mainly in order scale, fulfillment automation, and warehousing and distribution opportunities.

1. Orders and production demand: The platform sold 867 million items, up 36% year over year, with more than 93.9 million unique buyers and 9.2 items per buyer; units in Brazil rose 45%, Mexico 25%, Argentina 19%, and other markets 44%, indicating that product demand continues to expand across multiple Latin American markets.

2. Warehousing and automation: Mercado Libre's Dongguan China warehouse covers 60,000 square meters, has total capacity of over 5 million items, and handles a peak daily outbound volume of 500,000 items; it uses automated conveyance, sorting, and multi-line packing verification. In Mexico, Mercado Libre has launched an intelligent robotic fulfillment center, and the country has 17 large fulfillment centers and 124 sorting and delivery sites, with infrastructure area exceeding 2 million square meters.

3. Digitalization implications: Factories can monitor high-unit-volume categories and inventory preparation cadence across multiple markets, as well as the requirements that automated warehouse operations impose on packaging, sorting, and verification efficiency; before peak season, Mercado Libre's Latin American fulfillment space increased nearly 20% quarter over quarter, also signaling the need to prepare capacity and inventory in advance.

Service providers can focus on Mercado Libre's technology investment, fulfillment expansion, and seller operating tools.

1. Industry trends: Mercado Libre's net revenue and financial income reached USD 10.75 billion, up 45% year over year, marking 31 consecutive quarters of growth above 30%; GMV reached USD 23 billion, up 38%; advertising revenue rose 58% year over year, with e-commerce and advertising both accelerating.

2. New technology: AI investment increased by nearly USD 30 million quarter over quarter, with usage growing faster than investment; the company improved efficiency by selecting appropriate models and reducing model usage costs, and measured incremental returns using search click-through rates and conversion rates. Incremental revenue from LLM search has exceeded the additional model costs.

3. Customer pain points and solutions: 56,000 sellers used AI advisors to manage advertising, nearly quadrupling in three months; Engage+ uses AI to predict potential buyers and deliver brand advertising; on fulfillment, same-day and next-day delivery, the automated Dongguan warehouse, and Mexico's robotic fulfillment center provide entry points for service providers in warehousing, distribution, and advertising operations for sellers.

Marketplace operators can learn from Mercado Libre's proprietary AI shopping experience, fulfillment network, and advertising ecosystem.

1. Latest platform approach: Mercado Libre has made clear that it will not open product inventory to third-party AI shopping agents such as ChatGPT for now, and aims to build a complete agentic shopping experience within its own app to maintain users' habit of visiting the app directly; its proprietary AI shopping agent has been opened on a small scale in Brazil, Mexico, and Argentina.

2. Operations and merchant acquisition foundation: GMV reached USD 23 billion, up 38% year over year; items sold totaled 867 million, up 36%; unique buyers exceeded 93.9 million, up 22%. Brazil, Mexico, Argentina, and other markets all maintained growth, and Mexico's market share reached a new high.

3. Fulfillment and risk mitigation: Before peak season, Latin American fulfillment space increased nearly 20% quarter over quarter, and same-day and next-day orders rose 49% year over year; the Dongguan China warehouse and Mexico's robotic fulfillment center improved efficiency. The platform selects appropriate AI models, reduces costs, and measures CTR and conversion rates to avoid inefficient technology investment.

Researchers can focus on Mercado Libre's growth sustainability, path to AI commercialization, and choice of a closed ecosystem.

1. New industry developments: Net revenue and financial income reached USD 10.75 billion, up 45% year over year, marking 31 consecutive quarters of growth above 30%; GMV reached USD 23 billion, up 38%; advertising revenue rose 58% year over year, driven jointly by e-commerce and advertising.

2. New questions and business model: Mercado Libre has built its own AI shopping agent, currently under small-scale testing in Brazil, Mexico, and Argentina, but has not opened inventory to external platforms such as ChatGPT for now. It has chosen to complete agentic shopping within its own app, raising issues around platform traffic gateways, user habits, and ecosystem boundaries.

Policy and implications: AI investment increased by nearly USD 30 million quarter over quarter, with usage growing faster than investment, and incremental revenue from LLM search exceeding model costs; 56,000 sellers use AI advertising advisors, and Engage+ has launched in six sites; on fulfillment, Latin American fulfillment space increased nearly 20% quarter over quarter, 79% of parcels are delivered within 48 hours, and the Dongguan warehouse automation and Mexico's robotic center provide digitalization benchmarks.
