Mark Cuban is one of the wealthiest people in America, with an estimated net worth of $US4.1 billion, according to Forbes– but getting there wasn’t easy.

Cuban’s journey to becoming a billionaire included living in a “dumpy” apartment, where he stayed up late eating chicken wings and teaching himself to code. His unglamorous life of an aspiring entrepreneur included taking no vacation time for seven years and stealing towels from the Holiday Inn.

The late nights ended up paying off: The businessman and investor earned his fortune with a series of shrewd business deals starting in the 1990s, most notably the sale of his streaming site for $US5.7 billion in stocks. He continues to make major moves in the industry, most recently through selling a majority stake in his two cable networks, AXS TV and HDNet Movies, to Steve Harvey and Anthem Sports for an undisclosed sum,Deadline reports.

He even has nearly $US1 billion in Amazon stock alone, according to CNBC. The billionaire has previously said that Amazon and Netflix were his biggest holdings, though this is the first time he’s offered specifics.

Cuban recently sold his two long-standing cable networks — AXS TV and HDNet Movies — to Steve Harvey for an undisclosed sum.


Steve Harvey joined Anthem Sports & Entertainment to take over the two networks from Cuban. ASX TV’s programming includes wrestling and MMA fighting, and HDNet Movies shows a variety of films.

Cuban will continue on with the two companies as an equity partner, while Anthem is taking over operational control.



The savvy investor revealed his biggest holdings were in Netflix and Amazon. He has “close to a billion dollars” in Amazon stock alone.

Cuban previously said one of the best purchases he ever made was an unlimited first-class American Airlines ticket for $US250,000 — a promotion that the airline offered from 1981 to 1994. Cuban and 25 other ticket-holders continue to enjoy free airfare for life.

Despite his sometimes lavish spending, Cuban keeps a frugal mentality much of the time. For example, he insists on buying items in bulk, especially items he knows he’ll need such as razors and toothpaste.

And he advocates for people to achieve financial independence by paying off debt and stashing six months’ worth of income in the bank.

It’s a combination of relentless work ethic and financial smarts that have not only made Cuban one of the richest people in America, but kept him that way. As he once said, “Work like there is someone working 24 hours a day to take it all away from you.”
