Carlos Slim

Verified Timeline

Lore & Background

Carlos Slim was born on 28 January 1940 in Mexico City to Julián Slim Haddad and Linda Helú Atta, both Maronite Christians from Lebanon. His father taught him business principles early, and by age 11 he invested in a government savings bond, learning about compound interest. At 12 he made his first stock investment, buying shares of a Mexican bank, and by 15 he was a shareholder in Mexico's largest bank. He studied civil engineering at the National Autonomous University of Mexico, where he also taught algebra and linear programming, and later took economics courses in Chile. After graduating in 1961, Slim launched his career as a stock trader, often working 14-hour days. By 1965 his ventures had earned US$400,000 (equivalent to $4,086,589 in 2025), enabling him to start the brokerage Inversora Bursátil and acquire Jarritos del Sur, a bottling and soft drink company. In 1966, worth US$40 million (equivalent to $396,923,077 in 2025), he established Inmuebles Carso, a real estate agency and holding company. During the 1970s he expanded into construction, soft drinks, printing, real estate, mining, and other industries, and by 1972 he had established or acquired seven more businesses. In 1980 he consolidated his holdings as Grupo Galas. In the 1982 Mexican economic downturn, Slim invested heavily, acquiring depressed assets including Empresas Frisco, Industrias Nacobre, Reynolds Aluminio, Compañía Hulera Euzkadi, Bimex hotels, and Sanborn Hermanos. In 1984 he spent US$13 million to acquire Seguros de México, which later grew to be worth US$1.5 billion by 2007. In 1990 he led a consortium with France Télécom and Southwestern Bell to acquire Telmex from the Mexican government, which became the core of his fortune. By 2006, Telmex controlled 90 percent of Mexico's telephone lines, and Telcel operated almost 80 percent of the country's cellphones. His conglomerate now spans education, health care, manufacturing, transportation, media, mining, energy, entertainment, technology, retail, sports, and financial services.

Reader's Guide

Carlos Slim's significance lies in his transformation of Mexico's telecommunications sector and his accumulation of one of the world's largest fortunes. By acquiring Telmex during privatization, he secured a virtual monopoly that generated immense cash flow, which he reinvested across diverse industries. His conglomerate Grupo Carso accounts for 40% of listings on the Mexican Stock Exchange, giving him outsized influence over the national economy. Slim's business strategy—buying undervalued assets during crises and holding them for long-term cash flow—made his holdings nearly recession-proof. His wealth, peaking as the world's richest from 2010 to 2013, symbolizes both the potential of emerging-market capitalism and the concentration of economic power. As of 2016, he was the largest single shareholder of non-voting shares of the New York Times Company; in 2017, he sold half of his shares. As of July 2025, he remains Latin America's wealthiest individual, with a net worth of $99.1 billion. His career illustrates how privatization and strategic acquisitions can create enduring corporate empires.
