Serena Williams at 45: The Girl From Compton’s Courts Changed Everything

Forty-five years ago today, in Saginaw, Michigan, a girl was born who would grow up to own a sport that never saw her coming.

Serena Jameka Williams turns 45 on September 26, 2026, and if you’re looking for the right word for what she is, “tennis player” has never been big enough. She’s the standard. The blueprint. The reason a generation of Black girls picked up a racket and believed the court was theirs too.

From cracked concrete to center court

Every GOAT story has an origin, and Serena’s starts on public courts in Compton, California — cracked concrete, torn nets, her father Richard standing courtside shouting instructions while the neighborhood went on around them. Richard Williams had never held a racket before he decided his daughters would be champions. He taught himself the game from books and tapes, taught it to his wife Oracene, and then he taught it to Venus and Serena.

People laughed at that plan. Nobody’s laughing now.

The family moved to Florida in the early 1990s, the girls trained at Rick Macci’s academy, and Serena turned professional in 1995 at just 14 years old. Four years later, at 17, she won her first major singles title at the 1999 US Open. She didn’t just win — she played a kind of tennis the women’s game had never seen. Power like that, serves like bullets, movement like that, from a girl from Compton? The sport had to rearrange itself around her.

The case for the greatest

Let’s just lay the numbers out, because they still don’t feel real.

Twenty-three Grand Slam singles titles — the most by any player in the Open Era and the second-most of all time. Seven Australian Opens. Three French Opens. Seven Wimbledons. Six US Opens. She held all four major singles titles at the same time twice — the “Serena Slam” — and she did the Career Golden Slam in both singles and doubles, winning every major plus Olympic gold. She spent 319 weeks ranked No. 1 in the world, including 186 straight.

And she did it while pregnant — winning the 2017 Australian Open while two months along with her daughter Olympia, a fact the world only learned after. “I’m supposed to win,” she said later. “If I don’t win, it’s big news.”

That’s not just dominance. That’s a different category of athlete.

The second act

In August 2022, Serena told the world she was “evolving away” from tennis, in her own words — not retiring, evolving. Her last official match came at that year’s US Open. And true to the word, she didn’t slow down. She changed direction.

Motherhood became her favorite title. She and her husband Alexis Ohanian — they married in New Orleans in November 2017 — welcomed Olympia in 2017 and Adira in 2023. “I’ve been so focused on my career my whole life, but when I had a family and got married, I realized that there’s so much more to life,” she told PEOPLE. She meant it. The fiercest competitor tennis ever saw became the mom posting that being their mother is her favorite place to be.

And then there’s the boardroom. Serena started angel investing back in 2014, quietly, and brought Serena Ventures out of stealth in 2019. The $111 million debut fund backed companies like MasterClass and Tonal. This summer, she rebranded the firm as Starfire Ventures — because, as she put it, “I wanted it to be bigger than me. I wanted it to be about the team.”

Bigger than her is right. Starfire’s portfolio holds 16 unicorns. Nearly 70 percent of its companies are led by women or people of color. And the new Starfire Fund is writing $5M–$10M checks into tech and AI companies. “We are only investing in winners,” she said. “If we don’t feel the company is going to return our fund, we’re not going to invest in them.”

Read that again: a Black woman from Compton is now deciding which companies get to become the future. That’s not a second act. That’s a whole new arena, and she’s running it the same way she ran the baseline.

Why she matters

Here’s what the numbers can’t capture: Serena Williams changed what Black excellence is allowed to look like in real time, in front of the whole world, while the whole world watched her do it under pressure most of us will never know.

She took the boos, the body-shaming, the double standards, the officials who treated her differently — and she answered with trophies. She made power beautiful. She made no apologies for being exactly who she was: strong, loud, joyful, unbothered, Black. Every Black girl who ever got told she was “too much” got to watch Serena be too much all the way to 23 Grand Slams.

At 45, she’s not on the court anymore. She’s in the boardroom, at home with her babies, building the next thing. The girl from Compton’s courts didn’t just change tennis. She changed the idea of what’s possible — and she did it her way, the whole way down.

Happy birthday, Serena. The GOAT conversation starts and ends with you.
