MercadoLibre Expands 1P Rapidly: Is Margin Recovery at Risk?

Read MoreHide Full Article

Key Takeaways

  • MELI is rapidly expanding its first-party business to boost assortment and pricing competitiveness.
  • MELI's first-party growth is increasing logistics, warehousing and inventory management demands.
  • MELI continues prioritizing market-share gains as margin recovery remains challenging.

MercadoLibre's (MELI - Free Report) aggressive expansion of its first-party (1P) business is emerging as a key headwind to margin recovery. While the strategy is strengthening assortment, improving pricing competitiveness and helping the company gain share across key categories, the rapid scaling of inventory-led commerce is introducing structural profitability pressures that could weigh on operating leverage for longer than anticipated.

The company's 1P gross merchandise volume grew 69% year over year on a foreign exchange-neutral basis in the first quarter of 2026, significantly outpacing overall marketplace growth. The strategy has been particularly effective in consumer electronics, where MercadoLibre has expanded its competitive position through broader selection and sharper pricing. However, unlike the higher-margin third-party marketplace model, 1P requires inventory ownership, procurement spending and greater fulfillment intensity. As the business scales, associated logistics, warehousing and inventory management costs are likely to rise alongside volume growth, creating a more capital-intensive operating profile.

Gross margin contracted 300 basis points year over year in the first quarter of 2026, with rapid 1P expansion among the key drivers of the decline. Although profitability within certain mature 1P categories has improved, the broader business continues to absorb a growing share of corporate allocations as it scales faster than the overall marketplace. This dynamic suggests margin dilution will likely persist even as scale benefits gradually emerge.

MercadoLibre appears willing to continue prioritizing market-share gains and ecosystem expansion over near-term earnings optimization. As 1P continues to outpace the broader marketplace and absorb a growing share of corporate costs, the path toward margin normalization is expected to remain challenging.

MELI Faces Stiff Competition

MELI faces stiff competition from Amazon (AMZN - Free Report) and Alibaba (BABA - Free Report) , both of which have expanded logistics and inventory-led commerce capabilities to strengthen user engagement and pricing competitiveness. 

Amazon continues to scale its first-party retail network despite persistent fulfillment cost pressures, and its scale advantage sets a high bar for efficiency. Alibaba has likewise increased investments across direct retail and supply-chain infrastructure, navigating similar margin trade-offs as it defends its share. 

Unlike Amazon and Alibaba, MELI is expanding 1P while simultaneously ramping fintech, free shipping and logistics spend, which could keep profitability under pressure for longer.
