Serena Williams, 44, is officially eligible to compete in any WTA tournament for the first time since September 2022. She was reinstated on February 22, after she completed the mandatory six-month stint in the anti-doping testing pool. She could, theoretically, show up at any WTA tournament this year.
Most people on Kalshi seem to think she will.
But here's the thing about Serena Williams: she's always been a master of controlling her own narrative. Back in 2009, after a contentious match at the French Open, she famously said: "I'm, like, drama. And I don't want to be drama. I'm like one of those girls on a reality show that has all the drama, and everyone in the house hates them because no matter what they do drama follows them."
The Evolution That Wasn't
In August 2022, Williams announced she was "evolving away" from tennis in a first-person piece for Vogue. She wanted to focus on Serena Ventures, her venture capital firm that had already invested in companies like Masterclass and Impossible Foods. She wanted to expand her family.
Williams played her last match at the US Open that September, losing in the third round to Ajla Tomljanović. Twenty-three Grand Slam singles titles. Seventy-three career singles titles. Nearly $95 million in prize money. An icon who had fundamentally changed not just tennis, but how we think about female athletes.
That was supposed to be it. And for a while, it was. Then came December 2025.
Six Months of Pee Cups
News leaked that Williams had applied to be removed from the ITIA's retired players list. Translation: she had entered the anti-doping testing pool.
This is not a casual decision. The whereabouts system requires athletes to update their location daily and be available for testing for one hour every day, no matter where they are. Drug testers can show up at 6 a.m. asking for urine samples. They watch you closely as you provide those samples. They draw blood from your arm. It's invasive, inconvenient, and absolutely necessary for maintaining clean sport.
Nobody does this for fun.
Williams' immediate response to the leak? "Omg yall I'm NOT coming back. This wildfire is crazy."
By January, during an appearance on the Today Show, she laughed and said: "If I want to put it to bed… Listen, I want to go to bed, it's early."
Then on February 19, she posted a TikTok video of herself practicing serves alone on a tennis court. The caption: "I have not done this since September 2023."
The Venus Factor
If Williams does return, she won't be the only Williams sister back on tour. Venus, now 45, returned to competitive tennis seven months ago after a 16-month absence. She's only won one match, but she's been competitive. And if there's one thing that might lure Serena back onto the court, it's the prospect of teaming up with her sister for one more run at history.
The Williams sisters have won 14 Grand Slam doubles titles together. A 15th would be remarkable for reasons beyond just the number: their combined age would be 99.
The Case for the Return Of The Queen
At 44, Williams has to know this is her last chance. Venus is showing that competitive tennis in your mid-forties isn't impossible, just improbable. And Williams has always thrived on proving people wrong.
She's also a competitor to her core. The kind of person who won 10 Grand Slams after turning 30, who reached four major finals after giving birth while dealing with a life-threatening pulmonary embolism, who won the 2017 Australian Open while pregnant without dropping a set. This is not someone who goes gently into that good night.
The Case for No
Martina Navratilova tried to return to singles at 45 in 2002 and won just one match. Williams' last tournament was at the US Open 2022, where she lost. Walking to chase one more title at 44, knowing you might fall flat on your face?
The prediction market on Kalshi resolves to "Yes" if Williams competes in any WTA official tournament in 2026. Any tournament.
Almost all signs lead to “Yes”. We’ll see.
