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

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.

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.

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.

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.

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.

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.

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.

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

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.

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