Confidence rating:

Margot Perot and her family are assumed to have inherited all of Ross Perot's fortune after his death in July 2019.

The fortune was valued using proceeds Ross Perot collected selling stakes in two information technology service providers he founded. He sold Electronic Data Systems to General Motors for $2.5 billion in cash and stock in 1984 and received $850 million in cash. He was paid $700 million two years later after a series of disagreements led GM to buy his shares and remove him from the company's board of directors. He founded Perot Systems in 1988, and sold it to Dell for $3.9 billion in 2009, collecting $900 million. He had a net worth of $4.4 billion when he died on July 9, 2019.

The value of his cash investments was based on an analysis of these deals, dividends, market performance, insider transactions, taxes and political and charitable contributions. Perot spent $65 million on his presidential election campaign in 1992, according to Encyclopedia Britannica. He spent $10 million running for president four years later, according to the Federal Election Commission. That year he accepted public funding that curtailed his personal contributions.

James Fuller, a spokesman for the Perot family, declined to comment on the net worth calculation.


Birthdate: 11/15/1933
Family: Widowed, 5 children
Education: Goucher College

Margot Birmingham was born in 1933 and raised in Greensburg, Pennsylvania. While she was studying sociology and anthropology at Goucher College in Baltimore, she met Texas-born Ross Perot. The pair married in 1956.

After moving to Dallas, Margot worked as a teacher while Ross Perot started working in sales for IBM. He excelled as a computer salesman and Margot soon gave him $1,000 to start his own information systems company, Electronic Data Systems.

The company eventually went public and was bought by General Motors in 1984 for $2.5 billion. Ross Perot started Perot Systems in 1988, another information technology services company, and sold the business to Dell in 2009 for $3.9 billion.

Ross Perot is best known as a candidate for President of the United States in the 1992 and 1996 elections. After self-financing much of the campaign and appearing in the 1992 debate with then Governor Bill Clinton and Vice President George Bush, Perot captured almost one-fifth of the vote. That was the best result for a third-party presidential candidate since Theodore Roosevelt's 1912 run on the Progressive "Bull Moose" Party ticket.

Ross Perot died on July 9, 2019, survived by Margot and their five children.
