The wealthy, billionaire Mark Cuban may be best known as the previous owner of the Dallas Mavericks (he still retains a 27% minority stake) and former host of the show “Shark Tank”, but it turns out he has several diverse interests. A look at the website of Mark Cuban Companies shows the variety of companies he either owns outright or has invested in, and the list is impressive in both its volume and breadth.

Today, he oversees the Mark Cuban Foundation and Mark Cuban Companies, his venture capital and private equity firm. Mark Cuban Companies’ investments include businesses owned by minorities or women and those started by entrepreneurs with ties to the military. He also has a growing portfolio in the blockchain sector.
Cuban’s many business interests include health, fitness, eating well and the environment. Though he has financially backed upwards of 400 businesses, here are 10 companies Cuban is currently invested in.
Mark Cuban Cost Plus Drugs aims to produce and provide low-cost generic drugs and price them straightforwardly and transparently. A few years ago, when many people in the medical field were fed up with the corporate greed of pharmaceutical companies, Dr. Alex Oshmyansky, a physician and entrepreneur, reached out to Cuban via a cold email, and the company today has expanded to include a direct-to-consumer online pharmacy.
In 2014, Cuban invested $500,000 for a 30% stake of Gameday Couture, which started making officially licensed college apparel for women. Co-owners Kurt and Shawnna Feddersen began the Oklahoma-based company to help women look stylish while cheering for their favorite team.
By 2018, Gameday Couture had annual sales of $12 million. At the time of Cuban’s investment, Gameday Couture held licenses with more than 30 universities. In 2025, it holds over 350 licenses, including NCAA, NFL, MLS and Team USA NCAA licenses, and Cuban still owns a portion of the company.
In 2018, first-generation American Krystal Persaud decided to use her experience designing consumer electronics at a New York company to start Grouphug and emphasize sustainability. Her creation was window solar panels that connect to chargers for cell phones and other devices.
“While the sun hits your solar panel during the day, all of that energy gets stored in an internal battery, meaning you can charge your favorite devices day or night,” she said on a 2020 episode of “Shark Tank.” Sold on the promise of the concept, Cuban gave her $150,000 for a 25% stake in the company.
