Eduardo Costantini Net Worth

Eduardo Costantini has an estimated net worth of $1.2 billion, according to Forbes Real-Time Billionaires, Eduardo Costantini profile (figures as of October 20, 2026). That is up from $1 billion in 2017.

Eduardo Costantini is an Argentine businessman best known for building real estate projects through Consultatio S.A. After working as a stockbroker and finance executive, he founded the company in 1991. It went on to develop projects in Argentina and the U.S. He also founded Consultatio Asset Management in 1991. Alongside business, he created the foundation behind MALBA, the Latin American Art Museum of Buenos Aires, which features part of his art collection.

His wealth comes mainly from real estate. Forbes says his largest asset is his nearly 70% stake in Consultatio S.A., a Buenos Aires traded developer with projects in Argentina and the U.S. Forbes also notes that he is the majority shareholder of Consultatio Asset Management, a Buenos Aires firm with over $700 million of assets under management. Big projects tied to Consultatio include Nordelta, Puertos, and a $700 million luxury residential complex near Miami.

How Eduardo Costantini makes money

Costantini built his fortune by starting companies in finance and property, then turning them into long-running businesses. After earlier roles in finance, he launched Consultatio S.A. in 1991. Forbes says he still owns nearly 70% of the company, making it his biggest asset. The firm is listed in Buenos Aires and develops projects in Argentina and the U.S., giving him exposure to both home market projects and higher-end international real estate.

Several developments explain why his name is closely tied to Argentine real estate. Through Consultatio S.A., he developed Nordelta, described as the largest real estate venture in Argentina, and later Puertos in 2010. The company also built projects in Buenos Aires, including Catalinas Plaza and Alem Plaza. Outside Argentina, he developed projects in Uruguay and, through Consultatio Real Estate in the United States, worked on Oceana Key Biscayne and Oceana Bal Harbour in Miami.

Forbes net worth and other assets

Forbes has tracked Costantini as a self-made billionaire in real estate for years. Its estimate was $1 billion in 2017, then $1.5 billion in 2022. Forbes later put him at $1.5 billion in 2025. As of October 20, 2026, Forbes' real-time billionaires tracker showed $1.2 billion. The changes match a fortune centered on his holdings in Consultatio S.A. and his broader exposure to property development and investment management.

Real estate is only part of the picture. Forbes also says Costantini is the majority shareholder of Consultatio Asset Management, a Buenos Aires firm with over $700 million of assets under management. That gives him a second major business alongside development. His foundation also supports MALBA, the Museum of Latin American Art of Buenos Aires, which displays part of his collection. The museum is important to his public profile, though his wealth is tied to business assets.
