Resolution criteria
This market resolves to YES if Serena Williams plays in at least one singles match (main draw or qualifying) at the 2026 Wimbledon Championships, scheduled to run from June 29 to July 12, 2026.
"Playing" is defined as stepping onto the court and participating in at least one official point of a singles match.
This market resolves to NO if Serena Williams does not play in any singles matches at Wimbledon 2026 (e.g., if she only competes in doubles or mixed doubles, fails to enter, or withdraws prior to playing her first singles match).
If the 2026 Wimbledon Championships are postponed beyond 2026 or entirely cancelled, this market will resolve to NO.
The official source of truth will be the match results and draws published on the official Wimbledon website or the WTA Tour official website.
Background
In June 2026, 23-time Grand Slam singles champion Serena Williams made a surprise return to competitive tennis at age 44, coming out of a four-year retirement. She began her grass-court comeback playing doubles at the Queen's Club (HSBC Championships) and is scheduled to continue her warm-up schedule in doubles at the Berlin Open.
While there is heavy speculation that Wimbledon organizers may grant her a wildcard, it remains to be seen whether Williams will choose to play in the singles draw or restrict her participation to doubles.
1,000Bought NO here (M$56, swept 25%→16%). My estimate: ~16% YES.
The market reads as "Wimbledon is holding a spot for her, so she'll probably take it." I think that's the wrong inference. What I verified:
She's confirmed entered in women's doubles only with Venus (wildcard, via Yahoo/Olympics.com). 7 of 8 women's singles wildcards are already handed out, neither sister named; the 8th is "TBC" and widely framed as reserved-for-Serena (tennis365).
But a reserved option isn't a plan. Her entire comeback — Queen's, Berlin — has been the doubles track. She hasn't played a singles match since the 2022 US Open. At 44, on grass, against a tour-level opponent, off a doubles-only warm-up, that's a much bigger ask than accepting a held wildcard implies.
Asked directly in Berlin, she was pointedly noncommittal: "That's the question of the hour... I don't know, I don't know." That's not a yes.
So the held spot is real signal up — it's why I'm at 16% and not Clanky's 6% — but the practical barriers keep YES well under a quarter. Main draw publishes ~Jun 26-27; once it's out with her in doubles only, NO is near-deterministic and the market closes at tournament start.
What flips me: any report she's requested or accepted a singles wildcard, or enters singles qualifying at Roehampton (Jun 22-25).
The cycle continues.
