Five years before Hollywood retold their childhood in King Richard, Serena and Venus Williams were already tennis's most decorated sister act, six Wimbledon doubles trophies deep.
The film ended with two girls from Compton on the verge of stardom; the 2026 Wimbledon wild card list picks up where it left off, sending the sisters back onto the same doubles court for the first time in a decade.
Serena gives her 8-year-old daughter, Olympia, credit for talking her into it, saying, "she's always right. She's like, 'Mom, you should play with Venus.'"
Now that the pairing is locked into the women's doubles draw, the Kalshi market isn't nearly as convinced as Olympia was. The contract on Serena and Venus winning the title sits at just 8%.
A Long Layoff, a Low Ranking, and Double Duty
The skepticism starts with simple math: Serena hadn't played a competitive match in almost four years before returning this June at Queen's Club, and her one win there was just enough to put her on the doubles rankings at 593rd.
The form since hasn't settled any nerves either: she and Victoria Mboko won their opener before Mboko withdrew with a knee injury, and her next pairing, with Karolína Muchová, lost in the first round at the Berlin Open.
Days after the doubles wild card was confirmed, Serena also accepted a singles wild card, meaning she'll be splitting energy across two draws at 44. Venus, who just turned 46, has gone 1-5 in singles this year. None of that fits neatly into a spreadsheet, but it's exactly the kind of thing that keeps a number in the single digit.
Grass Is Where the Sisters Have Always Found Their Form
History pulls the other way.
Serena and Venus have won six Wimbledon doubles titles together, tied with Suzanne Lenglen and Elizabeth Ryan for the most by any pair in tournament history, though their last one came in 2016. Two of those six, in 2000 and 2002, were also won as wild cards, so this isn't unfamiliar ground.
A title this year would make them the oldest pair to win a Grand Slam doubles crown by a wide margin, well past the current record of 74 years and 303 days combined, set by Hsieh Su-wei and Barbora Strycova at Wimbledon in 2023. Serena's career win rate on grass sits at 87%, by far the best of her three surfaces, and that affinity doesn't just disappear after a layoff.
What Traders Might Be Missing
What's harder to price is everything that happens once the gates open. Hsieh and Strýcová, the pair holding that age record, were unseeded when they won in 2023, proof that an early-round run isn't a fantasy even without a favorable draw.
Add a Centre Court crowd that has never needed convincing to get loud for this family, and 8% starts to look less like a forecast and more like a floor.
The Wimbledon women's doubles tournament begins on Thursday, July 2, 2026.
Hollywood already gave their story one ending. Olympia, it turns out, might be angling for a sequel.
