Serena and Venus Williams – The Miami Dolphins/UFC
When these sisters aren’t busy tearing up tennis courts across the globe, they are also prolific businesswomen in their own rights. In 2009, they purchased a minority stake in the NFL team and still have it today.
In 2016, the Williams sisters also bought into the Ultimate Fighting Championship (UFC) along with other celebrities such as Tom Brady and fellow tennis player Maria Sharapova. The sisters both started their own clothing lines as well, with Venus owning EleVen brand and Serena having a deal with the Home Shopping Network.
