Mark Cuban has an estimated net worth of $6.8 billion, according to Forbes Real-Time Billionaires, Mark Cuban profile (figures as of October 20, 2026). That is up from $4.1 billion in 2019.
Mark Cuban is an American entrepreneur and investor known for tech, media, sports, and television. He became widely known after building Broadcast.com with Todd Wagner and selling it to Yahoo for $5.7 billion in 1999. He also became a familiar face on ABC's Shark Tank, where he appeared for 13 of the show's 15 seasons. His business work later expanded into entertainment through 2929 Entertainment and into basketball with the Dallas Mavericks.
His path to wealth started with software and online media. After being fired from a software shop for closing a $15,000 sale instead of cleaning the store, he decided to build on his own. He founded MicroSolutions and later sold it in 1990. Then he started Broadcast.com so he and Wagner could watch Hoosier basketball while living in Dallas. Today, Forbes tracks his fortune at $6.8 billion on its real-time billionaires tracker as of October 20, 2026.
How Mark Cuban built his wealth
Cuban's biggest money breakthrough came from online media. In 1995, he and Todd Wagner founded Broadcast.com, a video portal that grew quickly during the early internet era. Yahoo bought the company for $5.7 billion in 1999, turning that startup into the defining deal of his career. Before that, he had already built and sold MicroSolutions in 1990, after starting it with support from former customers in Dallas.
His wealth later spread across sports, entertainment, health care, and startup investing. He was the former principal owner of the Dallas Mavericks and is now a minority owner. In December 2023, he sold 58% of the team for an estimated $2 billion, pre-tax. He is also cofounder of Cost Plus Drugs, launched in January 2022 to lower prescription drug prices. On Shark Tank, he invested more than $22 million during his time on the show.
Forbes net worth timeline
Forbes placed Cuban at $4.1 billion in 2019, then $4.3 billion in 2020, $4.4 billion in 2021, and $4.7 billion in 2022. Those estimates fit a business profile built around media, sports, and investing. Forbes also describes him as self-made. His long-running stake in the Mavericks, plus his earlier Broadcast.com windfall and other ventures, remained central parts of the picture during those years.
The Forbes estimate then moved to $4.6 billion in 2023, $5.4 billion in 2024, $5.7 billion in 2025, and $6 billion in 2026. Forbes also showed $6.8 billion on its real-time billionaires list in October 2026. That later stretch came after his December 2023 Mavericks sale while he still kept a minority stake. By then, Cost Plus Drugs and his broader investing record were also part of the story.
