According to Forbes, former Dallas Mavericks majority owner Mark Cuban is worth in the area of $6 billion. Most of which was amassed by selling his website, Broadcast.com, to Yahoo! in 1999.
Cuban then purchased a majority stake in the Mavs in 2000, and the team’s value skyrocketed before he sold his controlling stake in the team to the Adelson and Dumont families in 2023.
But Cuban has made plenty of other savvy investments along the way, many of which were chronicled on the show Shark Tank, which features inventors pitching their products to Cuban and other notable investors in hopes of receiving an offer of seed capital in exchange for a stake in the company.
Cuban has invested in hundreds of products on the show. While some have failed to get off the ground, plenty of others have flourished. One, in particular, is the product that Cuban is most proud of and that made him the most money.

“Have you heard of BeatBox Beverages?” Cuban asked the hosts. “It’s big on college campuses and killing it. So, I gave them a million dollars for 33 percent of the company, and I’ve been diluted now, but they just did a fundraising at $200 million.”
BeatBox is a brand of premixed alcoholic beverages that range from 6 percent ABV in zero-sugar options to 11.1 percent in its wine-based and malt-based drink recipes.
Cuban also mentioned making a large return on his investment in the flushable bathroom wipes brand, Dude Wipes.
Safe to say, even without having full control of the Mavs, Mark Cuban is doing okay for himself these days.
