Mark Cuban‘s business career has taken him from an internet broadcasting venture that sold for billions of dollars to a pharmaceutical company built around a very different proposition. According to a Forbes report, in 1999, Yahoo acquired Broadcast.com in a deal valued at $5.7 billion, turning Cuban’s early bet on online media into one of the defining transactions of the dot-com era. More than two decades later, he entered the prescription medicine market with Cost Plus Drugs, an online business intended to make the cost of medicines easier to understand and, in many cases, lower. The two ventures operate in very different industries, but both reflect Cuban’s willingness to challenge established ways of doing business.
How Broadcast.com turned Mark Cuban’s internet venture into a $5.7 billion Yahoo deal
Broadcast.com began in 1995, when Cuban and fellow Indiana University graduate Todd Wagner set up a business to deliver audio and video over the internet. The idea developed during a period when streaming media was still unfamiliar to most households and online connections were far less capable than they are today. Cuban and Wagner saw an opportunity to distribute content to people who wanted access to broadcasts beyond the reach of conventional radio and television.Their business attracted growing attention as internet companies became increasingly valuable during the late 1990s. Yahoo, already expanding beyond its original role as a web directory, agreed to acquire Broadcast.com in 1999 in a transaction worth approximately $5.7 billion. The deal was completed largely through shares, reflecting the extraordinary valuations attached to internet businesses at the time.Broadcast.com had moved from a relatively young online venture to a company acquired for billions within four years of its founding. The transaction also placed Cuban among the entrepreneurs who benefited substantially from the expansion of internet investment before the dot-com market collapsed.
Mark Cuban’s $6.8 billion fortune extends beyond his landmark internet deal
Cuban did not remain focused on online media after the Yahoo transaction. Over the years, his business interests extended into professional sport, entertainment and technology. His wealth has continued to reflect a range of holdings rather than a single business. Forbes’ profile, updated in September 2026, lists his estimated real-time net worth at $6.8 billion as of 22 October 2026. The publication also reports that he sold a 58% stake in the Mavericks in December 2023 for an estimated $2 billion before tax, while retaining a minority interest in the team.As reported by Forbes, Cuban’s route into business was not confined to technology. He has spoken about selling goods door to door as a child and taking on work, including disco lessons, to help pay for his university education. After graduating from Indiana University, he worked in the technology sector before establishing businesses of his own.His early experience with Broadcast.com remains central to his public story, but his later ventures have covered problems far removed from internet broadcasting. Cost Plus Drugs, launched in 2022, would bring him into an industry where pricing is closely tied to manufacturers, wholesalers, insurers, pharmacy benefit managers and pharmacies.
How Cost Plus Drugs aims to change the way Americans pay for prescriptions
Mark Cuban Cost Plus Drug Company launched in January 2022 with the stated aim of making prescription medicines more affordable. Cuban co-founded the venture with physician Alex Oshmyansky, who had worked on the idea of a lower-cost pharmaceutical supply model before partnering with the entrepreneur.The company operates through an online platform that allows customers to look up medicines and purchase eligible prescriptions. Its approach places an emphasis on showing how the final price is calculated, rather than presenting the cost as a single figure with little explanation of the components behind it.Under its stated pricing model, Cost Plus Drugs adds a 15% mark-up to the cost of a medicine, alongside a pharmacy labour charge and shipping. The model was designed to offer a more transparent alternative to parts of the conventional prescription drug market, where the price paid by a patient can depend on insurance arrangements, negotiated discounts and other intermediaries.
From a $5.7 billion Yahoo deal to challenging prescription drug prices
The sale of Broadcast.com and the creation of Cost Plus Drugs sit more than 20 years apart, and the businesses have little in common at first glance. One capitalised on the growing appetite for online audio and video; the other was established around the cost and availability of prescription medicines.Yet both have involved Cuban backing a business model that offered an alternative to existing arrangements. Broadcast.com sought to make media available through the internet at a time when traditional broadcasting dominated. Cost Plus Drugs aims to give customers another way to obtain eligible medicines, with a pricing formula intended to be easier to understand.
