Mark Cuban has a net worth of $6 billion, built through a sequence of entrepreneurial ventures beginning with a $6 million software sale in 1990 and accelerating to a $5.7 billion internet company exit in 1999. He is best known as the former majority owner of the NBA’s Dallas Mavericks, a longtime investor on Shark Tank, and the founder of the prescription drug discount platform Cost Plus Drugs.
Updated March 2026: According to the Bloomberg Billionaires Index, Mark Cuban’s net worth stands at approximately $6 billion, reflecting the residual value of his Dallas Mavericks stake, diversified startup investments, and the growing Cost Plus Drugs platform.
Mark Cuban was born on July 31, 1958, in Pittsburgh, Pennsylvania, to a working-class Jewish family. His father, Norton Cuban, was an auto upholsterer. From an early age, Cuban exhibited an entrepreneurial instinct: at 12, he sold garbage bags door-to-door to buy a pair of basketball shoes, later expanding into stamp trading and newspaper route ownership.
He attended Mount Lebanon High School and began his freshman year at the University of Pittsburgh before transferring to Indiana University’s Kelley School of Business, where he earned a Bachelor of Science in Management in 1981. While a student, he ran a bar, taught disco dancing lessons, and sold chain letters — each venture informing his understanding of small-scale economics and customer acquisition. After briefly working as a bartender in Indiana, he moved to Dallas in 1982 with $60 in his pocket, per Wikipedia.
Cuban’s first significant venture in Dallas was MicroSolutions, a computer consulting company he founded in 1983 after being fired from a software retailer. He taught himself programming and networking, growing MicroSolutions to $30 million in annual revenue before selling it to CompuServe in 1990 for $6 million — netting Cuban approximately $2 million after taxes, per Wikipedia.
In 1995, Cuban and longtime friend Todd Wagner co-founded AudioNet (later renamed Broadcast.com), an early internet streaming service that broadcast radio stations, sporting events, and audio content online. The timing was exceptional: as internet adoption accelerated through the late 1990s, Broadcast.com became one of the most-visited sites on the web. Yahoo acquired Broadcast.com in 1999 for $5.7 billion in stock — then the largest internet acquisition in history. Cuban’s personal stake in the transaction was worth approximately $1.4 billion at closing, per Bloomberg. He protected much of that value by purchasing put options on Yahoo stock in advance of the lockup expiration — a hedge that proved prescient when Yahoo’s share price collapsed during the dot-com bust.
In January 2000, Cuban purchased a majority stake in the Dallas Mavericks NBA franchise for $285 million, widely considered overpaying at the time. His high-profile courtside presence, willingness to engage with fans and media, and aggressive investment in player talent transformed the Mavericks from a perennial lottery team into a championship contender. Dallas won the 2011 NBA Championship, defeating LeBron James’s Miami Heat. In December 2023, Cuban sold the majority of his Mavericks stake (approximately 73%) to the Adelson family’s Las Vegas Sands for a valuation of approximately $3.5 billion, retaining 27% ownership, per Bloomberg Billionaires.
Cuban joined Shark Tank in its second season (2012) and appeared through Season 16 (2025), investing approximately $20 million across 85+ deals in startups spanning technology, consumer products, and healthcare, per IMDb records and network reporting.
His most significant post-Mavericks venture is Cost Plus Drugs, a prescription drug transparency platform he founded in 2022 that sells generic medications at dramatically reduced prices by eliminating pharmacy benefit manager markups. By 2025, the platform had expanded to include multiple therapeutic categories and was actively advocating for PBM regulatory reform before Congress, per STAT News.
Cuban married Tiffany Stewart on September 25, 2002, in Barbados. The couple has three children: daughter Alexis Sofia (born 2003), daughter Alyssa (born 2006), and son Jake (born 2010). Cuban has been notably family-focused in public interviews, citing his children as the primary reason he declined several political overtures, including reported discussions about a 2024 presidential or vice-presidential run.
The family resides in Dallas, Texas. Cuban is a pescatarian, a Pittsburgh Steelers fan, and a vocal advocate for independent political thought — he has donated to candidates from both major parties and frequently criticized partisan tribalism. In March 2026, he publicly praised emerging Democratic leaders’ policy direction, per Business Insider.
Cuban donated $6 million to Indiana University in 2024 to support rugby and athletic programs, and has funded the Fallen Patriots Fund and multiple education initiatives. He has also donated significant amounts to local Dallas charities and disaster relief efforts.
In the business world, Cuban’s trajectory is often compared to that of fellow entrepreneurs like Elon Musk and motivational figures such as Tony Robbins, who both built multi-billion dollar enterprises from early-stage ventures. His television presence alongside Gordon Ramsay — another television personality with significant business ventures — has made him one of the most recognizable business faces in American media.
Mark Cuban’s net worth is approximately $6 billion as of 2026, according to the Bloomberg Billionaires Index. His wealth is anchored by the proceeds and retained equity from the 2023 Dallas Mavericks majority stake sale, income from Cost Plus Drugs and startup investments, and assets preserved from his 1999 Broadcast.com windfall.
Cuban’s primary wealth-creation events were the 1999 sale of Broadcast.com to Yahoo for $5.7 billion and the 2023 partial sale of his Dallas Mavericks stake at a $3.5 billion franchise valuation. He amplified these gains through disciplined hedging, diversified startup investing, and the creation of new ventures including Cost Plus Drugs and 2929 Entertainment.
Mark Cuban sold the majority of his Dallas Mavericks stake (approximately 73%) to the Adelson family in December 2023 for a valuation of approximately $3.5 billion. He retains a 27% minority ownership stake in the franchise and remains involved in team decisions in a non-controlling capacity.
