By Brazil Stock Guide – TikTok Shop, the e-commerce arm of the popular social media platform, has swiftly gained ground in Brazil, surpassing expectations with $46.1 million in monthly sales just three months after its launch. This marks a staggering 4,500% increase in its transaction volume, putting significant pressure on established players like Mercado Livre (MELI34), the leader in Brazil’s online retail market.
The growth of TikTok Shop, which launched in May 2025, has been nothing short of remarkable. According to a report by Itaú BBA, in just three months, the platform saw its gross merchandise volume (GMV) surge from $1 million in May to $46.1 million by August. In June, sales hit $10.1 million, and by July, they reached $25.7 million. This meteoric rise positions TikTok Shop as a formidable competitor in Brazil’s e-commerce landscape.
Itaú BBA’s analysis points out that TikTok Shop now accounts for approximately 2% of Mercado Livre’s sales in Brazil, where the Argentine company holds a market share of over 40%. The report highlights that around 50% of TikTok Shop’s Brazilian sales come from its “Shop” tab, which mirrors the user behavior seen on Mercado Livre’s platform, further intensifying the competition.
In addition to TikTok Shop, other players like Shopee have also been expanding aggressively in Brazil, with year-on-year growth rates between 60% and 70%, compared to Mercado Livre’s 30%. Amazon (AMZN), meanwhile, continues to refine its logistics and vendor integration strategies, contributing to the growing pressure on Mercado Livre’s market dominance.
To maintain its leadership position, Mercado Livre will need to continue investing in logistics, payment systems, and loyalty programs, despite uncertainties over short-term profitability. Itaú BBA suggests that with the competitive landscape becoming increasingly volatile, Mercado Livre will have to adapt to market shifts, especially given economic challenges in Argentina.
