Broadcast.com Sale to Yahoo
Mark Cuban sold Broadcast.com, the streaming and radio company he co-founded, to Yahoo in 1999 for about $5.7 billion in stock and cash. The deal made Cuban one of the most notable tech-era entrepreneurs and gave Yahoo a major stake in internet audio and video streaming. The transaction is documented in SEC filings and reported by financial outlets including Forbes, which details the valuation and terms of the sale.
After the sale, Cuban used a large portion of the proceeds to invest in sports, media, and technology ventures, including becoming the owner of the Dallas Mavericks. The Broadcast.com acquisition is widely cited as one of the defining exits of the late 1990s internet boom and remains a reference point in discussions of high-value startup sales.
Other Major Ventures and Investments Sold or Exited
AXS TV and Stake Exits
Cuban has held ownership stakes in media and entertainment properties, including AXS TV, a network focused on live music and entertainment programming. He has sold or reduced stakes in several media ventures over time, often through private transactions that were not disclosed in full detail to the public.
Beyond media, Cuban has exited or scaled back interests in various technology and data companies, often reinvesting the proceeds into new startups and public equities. His portfolio moves are frequently tracked by financial analysts and reported by outlets such as Forbes, which provides updates on his holdings and investment activity.
SEC Filings and Public Disclosures
Cuban's sales of company stakes and large equity positions are often reported through SEC filings, including Form 4 and Schedule 13D submissions that detail transactions by major shareholders. These filings provide exact dates, share counts, and transaction values for sales of publicly traded company stock.
Investors and researchers can review these filings directly through the SEC's EDGAR database, which offers searchable records of Cuban's reported transactions. The data is used by analysts to understand his portfolio shifts and to infer which businesses or public companies he has exited or reduced positions in.
Current Business Interests After Major Exits
Dallas Mavericks Ownership
Cuban remains the owner of the Dallas Mavericks, an NBA franchise he purchased in 2000 after the Broadcast.com sale. The team has won multiple playoff series and reached the NBA Finals under his ownership, with Forbes regularly publishing valuations and financial summaries of the franchise.
Shark Tank and Media Ventures
Cuban is a long-time investor and panelist on the ABC show Shark Tank, where he evaluates business pitches and invests directly in startups. The show has become a platform for entrepreneurs to secure funding and public visibility, and Cuban's participation is a key part of its format and appeal.
He continues to invest in early-stage companies through his personal fund and has backed businesses in areas such as artificial intelligence, healthcare technology, and consumer apps. His current portfolio includes both public and private holdings, with transactions and stakes often reported through SEC filings and financial news sources.
