Biography

Mark Cuban net worth is estimated at $5.7 billion in 2025, with the foundation coming from his 1999 sale of Broadcast.com to Yahoo! for $5.7 billion in stock — one of the largest internet-era acquisitions. Wisely hedging Yahoo! stock before the dot-com crash with equity swaps, Cuban preserved most of his gains and used the fortune to purchase the Dallas Mavericks in 2000 for $285 million, which he sold a majority stake in to Miriam Adelson in 2023 at a valuation of $3.5 billion. His wealth has been further compounded through appearances on Shark Tank (since 2011), investments in over 60 startups on the show, and his launch of Cost Plus Drugs in 2022 — a pharmaceutical company that sells generic drugs at cost-plus 15%, disrupting the prescription drug industry.
