Mark Cuban is worth $5.7 billion. Here's how the 'Shark Tank' investor makes and spends his fortune.

According to Forbes, he is ranked the 570th richest person in the world.

In 1982, he started his own company, MicroSolutions, which he sold eight years later for $6 million. Cuban made $2 million off the deal, The Dallas Morning News reported.

Broadcast.com began as a radio company called Audionet. The site streamed broadcasts of sports games, political conventions, and other events. Cuban took control of the company in 1995 and netted $1 billion when he sold his shares.

To this day, it holds the Guinness World Record for the biggest purchase ever conducted over the internet.

Cuban called the plane one of the smartest purchases he's ever made. "It's obviously brutally expensive, but time is the one asset we simply don't own," he wrote for Men's Journal in 2018. "It saves me hours and hours."

He went on to add another private jet and a 288-foot yacht named "Fountainhead" to his portfolio in later years.

Cuban raised his profile by sitting courtside at Mavericks games and drew attention for his animated reactions and media outbursts.

His frequent criticisms of NBA referees have cost him a small fortune. As of February 2018, the NBA had fined him close to $2.6 million for his comments and antics over the years, The New York Times reported.

The tab included a $90,000 bottle of Armand de Brignac Champagne. Cuban also left a $20,000 tip.

"Worth every penny," he told Page Six.

A 2023 Forbes estimate valued the Mavericks at $4.5 billion. Cuban is still a minority owner of the team. 

Cuban has supported charitable organizations such as Autism Speaks, Cedars-Sinai Medical Center, the Christopher & Dana Reeve Foundation, and the Elton John AIDS Foundation.

In 2012, he donated $40,000 to save the local Greenville Avenue St. Patrick's Day Parade when the group organizing the annual event ran out of funding.

"You just can't let a Dallas tradition like that die," Cuban told local NBC News affiliate KXAS.

The Category 4 storm killed an estimated 2,975 people and left $80 billion in damage across Puerto Rico. It took 11 months to fully restore power across the island.

A 2018 Sports Illustrated report documented allegations of rampant misogyny and sexual harassment within the Mavericks organization, leading to an official NBA investigation, which uncovered "improper workplace conduct" by the team's former president and CEO, among other findings.

Cuban told Sports Illustrated that he had no knowledge of the reported toxic workplace culture since he was "not involved in the day-to-day" of the organization.

"I'm embarrassed, to be honest with you, that it happened under my ownership, and it needs to be fixed," he said.

As part of the NBA's investigation into the Mavericks workplace culture, Cuban donated $10 million to women's causes and domestic violence awareness.

Cofounded with Todd Wagner in 2003, 2929 Entertainment owns the production companies behind films like "Akeelah and the Bee" and "Good Night, and Good Luck."

The show, in which contestants competed to win $1 million of Cuban's money, was panned as a ripoff of "The Apprentice" and canceled after six episodes.

"Shark Tank" has aired for 15 seasons. Cuban joined as a "guest shark" in the show's second season and became a regular judge.

Cuban told Forbes in 2022 that he's invested $29 million in at least 85 startups and small businesses over 13 seasons of "Shark Tank." His most successful investments have been in the preschool app Brightwheel and flushable Dude Wipes.

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, Deadline reported.

Cuban continued on with the two companies as an equity partner, while Anthem took over operational control.

In 1999, Cuban paid $17.6 million for a 24,000-square-foot mansion in Dallas, where he and his family still live. The 7-acre property features 10 bedrooms, 16 bathrooms, a tennis court, a swimming pool, and a separate guest house in the back.

In 2018, Cuban also bought a $19 million vacation villa in Laguna Beach's exclusive Montage Residences community. The modern six-bedroom home has walls that disappear to open up to the outdoor space and a private pool.

Cuban told Fox Business News that he has "close to a billion dollars" in Amazon stock alone.

Cuban and 25 other ticket-holders continue to enjoy free airfare for life, The Hustle reported.

For example, he insists on buying items in bulk, especially items he knows he'll need such as razors and toothpaste.

"The money you save by investing in bulk will provide a better return on investment than any investment vehicle on the planet," he told NPR in 2013.

He also told Vanity Fair in 2017: "You're better off buying two years worth of toothpaste when it's on 50% discount. That's an immediate return on your money."

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

Cuban told Forbes in 2022 that he'd invested $100 million in the company, which, according to its website, aims "to disrupt the drug industry and to do our best to end ridiculous drug prices."

Cost Plus Drugs sells medications at the cost they purchase them for plus a set 15% markup, a pricing model that CVS then adopted in 2023.

"If we get this right, this will be the most impactful thing I've ever done," he said.

As he once said, "Work like there is someone working 24 hours a day to take it all away from you."
