Key insights
- The author believes MercadoLibre's advertising business is undervalued by the market. Its high-quality traffic and integrated ecosystem, similar to Amazon, could drive significant margin expansion. While credit risk in Latin America remains a concern, continued growth in ad revenue could substantially boost MELI's earnings in the long term, making it a bullish signal for US investors holding the stock.
I believe the market underestimates how important Ads could become for $MELI.
Everyone focuses on ecommerce or Mercado Pago, but Ads might eventually be one of the highest margin businesses they have.
The setup is already there: - ~$29B revenue in 2025 - ~$278B TPV last year - ~78M fintech monthly active users - 120M+ annual unique buyers - Ads revenue grew something like 67% YoY in Q4
And the key thing is the traffic quality.
People on MercadoLibre usually arent browsing randomly. Theyre already searching for products and ready to buy. Thats insanely valuable ad inventory. Amazon figured this out years ago and now advertising is one of their best businesses.
Feels like MELI is slowly heading in the same direction.
The ecosystem is what makes it hard to compete with: merchant sells on MELI -> pays for sponsored placement -> uses Mercado Pago -> maybe takes credit -> ships through MELI logistics.
Every piece reinforces another piece.
What I dont think people fully appreciate is what higher-margin ad revenue can do to the earnings profile over time. Ecommerce margins are fine. Lending can get cyclical. But ad dollars layered onto an existing marketplace can scale very efficiently once merchants start depending on visibility.
And LatAm still isnt close to saturation: - ecommerce penetration still below US/China - cash usage remains high - lots of SMBs still early digitally - digital advertising market still developing
Biggest risk is still credit imo. Loan book already hit ~$12.5B and if the macro gets ugly in Brazil or Argentina, thats where pressure shows up first.
If Ads keeps scaling anywhere close to current rates, I think people are materially underestimating what MELI earnings could look like 5 years from now.
