Marcos Galperin Net Worth

Marcos Galperin has an estimated net worth of $7.7 billion, according to Forbes Real-Time Billionaires, Marcos Galperin profile (figures as of October 20, 2026). That is up from $1.6 billion in 2019.

Marcos Galperin is an Argentine technology entrepreneur best known for co-founding MercadoLibre in 1999. Before that, he worked at YPF and also spent time as a summer intern at JPMorgan. MercadoLibre began as an online marketplace and grew into a major e-commerce platform across Latin America. After leading the business for 26 years, he stepped down as CEO in 2026 and became executive chairman.

His wealth is tied to MercadoLibre, which operates in 18 Latin American countries and Portugal. The company went public on the Nasdaq in 2007, a key step in turning its regional growth into major value. Forbes tracked his fortune at $7.7 billion on its real-time billionaires tracker as of October 20, 2026. He is self-made, and Forbes places him in the Technology industry, with wealth built from e-commerce.

How Marcos Galperin makes money

Galperin made his fortune by building MercadoLibre, the company he co-founded in 1999. Forbes describes it as an e-commerce platform and notes that it became the eBay of Latin America. That business spread across 18 Latin American countries and Portugal, giving it a broad regional base. MercadoLibre's 2007 Nasdaq listing helped bring public market value to the company and turned its founder's stake into the main source of his wealth.

His early work outside MercadoLibre included time at Argentine oil company YPF and a summer internship at JPMorgan. Later, MercadoLibre grew large enough that eBay became its largest shareholder with 18%. In 2016, eBay sold that stake for more than $1 billion. In 2026, Galperin moved from the CEO job to executive chairman after 26 years leading the company.

How Forbes' estimate changed

Forbes' annual estimates for Galperin moved sharply as MercadoLibre grew and markets changed. Its World's Billionaires List placed him at $1.6 billion in 2019, $2 billion in 2020, and $6.1 billion in 2021. The estimate then fell to $3.9 billion in 2022 before rising again to $4.9 billion in 2023. Those swings show how closely his fortune is linked to the public value of the company he founded.

The rebound continued in later years. Forbes put his wealth at $6.3 billion in 2024 and $8 billion in 2025, then at $7.2 billion on the 2026 World's Billionaires List. Forbes' real-time tracker later showed $7.7 billion in Oct 2026. Over that stretch, the big drivers were the scale of MercadoLibre's e-commerce business, its public market valuation, and Galperin's long-running leadership role before his 2026 transition.
