Early Life

He was born July 31, 1958, in Pittsburgh, Pennsylvania. He grew up in a Jewish working-class family in the suburb of Mount Lebanon. He has two brothers, Brian and Jeff. Cuban found his entrepreneurial spirit early. When he was 12, he sold garbage bags to make enough money to buy an expensive pair of basketball shoes. Later, he made money selling stamps and coins.

When he was 16, he took advantage of a newspaper strike at the Pittsburgh Post-Gazette by going to Cleveland to get newspapers and bringing them to Pittsburgh.

Cuban skipped his senior year of high school and enrolled at the University of Pittsburgh, where he joined the Pi Lambda Phi fraternity. After one year at Pitt, he transferred to Indiana University. He graduated from IU's Kelley School of Business in 1981 with a B.S. in Management.

Early Career

On July 7, 1982, Cuban moved to Dallas, Texas, where he worked as a bartender and as a salesperson for Your Business Software, one of the earliest PC software retailers in Dallas. He was fired less than a year later when he met with a client to procure new business instead of opening the store.


Cuban founded MicroSolutions with support from his previous customers at Your Business Software. MicroSolutions was initially a software reseller and system integrator. One of Cuban's largest clients was Perot Systems.  He grew the company to more than $30 million in revenue. In 1990, he sold MicroSolutions to Compuserve for $6 million. He netted about $2 million on the deal after taxes.

American Airlines Unlimited Pass

On the night the deal closed, Mark and his co-founders and friends went to a steakhouse to celebrate. During drinks someone asked Mark what he was going to do with his new wealth. The steakhouse had a phone on the table. Mark picked up the phone, dialed American Airlines, and purchased an unlimited lifetime pass for $250,000. He later purchased a companion pass for $150,000. By 1994, American Airlines had discontinued offering these passes, but Mark was still able to fly anywhere in the world on a moment's notice for free without a reservation. American stopped offering the passes after one owner used his to fly more than 40 million miles.

American allows its remaining 20-30 lifetime pass owners to gift the passes to someone else one time. Mark ultimately gifted his pass to his father, and then after his father passed away, the pass was gifted to a friend.

Predicting the Dotcom Bubble Burst

Mark's smartest financial move of all time was being able to foresee that the dotcom bubble would eventually burst. On the day the Broadcast deal officially closed, Yahoo's stock was trading at $163 per share. Six months later, when Cuban's lockup agreement expired, the price per share was roughly the same.

However, Cuban's firm belief that the internet bubble was about to burst led him to sell 100% of his Yahoo shares as soon as he was his lockup expired.

This move netted Mark $2.5 billion in cash.

Over the next year and a half as the bubble eventually burst, Yahoo's stock price slid from $100 to $70 to $50 to $30.

By October of 2001, Yahoo hit an all-time low of $8.11 per share. That's a 95% drop compared to $163 a share when Cuban sold. In other words, Mark's $2.5 billion worth of stock could have become worth as little as $125 million. Still a nice fortune, but not enough to buy an NBA team, movie studio, cable network, private jets…

Dallas Mavericks

Mark bought the Dallas Mavericks from Ross Perot for $285 million in 2000. Mark had no partners in the deal. The Mavericks won the 2011 NBA Championship.

Additionally, "Shark Tank"  has won three Primetime Emmy Awards for Outstanding Structured Reality Program while Cuban has been a part of it.
