By the time she won her first Grand Slam singles title at the 1999 US Open, the takeover had officially begun. Over the next two decades she built one of the most dominant careers in sports history: 23 Grand Slam singles titles, 319 weeks at world number one, four Olympic gold medals, and the Serena Slam, completed twice. Her game was built on power and precision that the sport had never seen from a woman, but her presence was just as revolutionary. She brought muscle, emotion, fashion, motherhood, joy, rage, and unapologetic greatness into a sport that spent years trying to make her shrink, and she responded by winning more. She played through injuries that would have ended other careers, returned from a pulmonary embolism that nearly killed her after the birth of her daughter, and competed at the highest level into her forties. The GOAT conversation in tennis is not a conversation. It is a formality.

What she built alongside the titles is the part that will outlast the trophies. She became a venture capitalist, investing in companies founded by women and people of color at a moment when that capital was genuinely scarce. She spoke about the racism and sexism she encountered in the sport with a directness that made people uncomfortable, which was the point. She is married to Reddit co-founder Alexis Ohanian and is a mother to two daughters, Alexis Olympia and Adira River. In the summer of 2026 she returned to professional tennis, because when you are Serena Williams, retirement is just another decision you get to make twice.
