Serena Williams | $250 Million

Serena Williams went through rigorous tennis training at the early age of three, along with her sister Venus. Both were groomed by their father to be tennis superstars. She won her first major championship in 1999, Grand Slam in 2003, and held the number one spot in the Women’s Tennis Association rankings countless times over throughout her stellar career. She and Venus had teamed up together and won a series of doubles titles.

Apart from her profession as a professional tennis player, Williams also has several investments in 66 startup companies through her company, Serena Ventures, having nearly 20 corporate partners. Her career prize money of $94 million is worth twice as much as any other athlete has made. Today, the prolific tennis player has an estimated net worth of $250 million, which will certainly increase in the following years with her business ventures.
