Billionaire investor Mark Cuban is selling a majority stake of the Dallas Mavericks to Miriam Adelson and her family — the largest shareholders in Las Vegas Sands , a source familiar with the deal told CNBC. Adelson is selling $2 billion worth of company stock, or roughly 10% of her stake, according to an announcement from the company. Las Vegas Sands disclosed in filings Tuesday that it will buy $250 million worth of Adelson's shares. Owning a sports franchise will be a significant departure from the activities that Miriam Adelson and her late husband were known for. As a medical doctor, Miriam Adelson is also widely known for her focus on addiction.
