Wimbledon WTA: Serena Williams vs Maya Joint

Platform comparison

Market context

Serena Williams, 44, is set to make her highly anticipated singles comeback at Wimbledon against 20-year-old Australian Maya Joint, ranked 53rd, in the first round originally scheduled for 29 June 2026. The match, now confirmed for Tuesday, presents a stark age and experience contrast, with Williams returning after nearly four years away from competitive singles play since the 2022 US Open.

Historically, comeback players in their mid-40s at Wimbledon face steep odds, yet wildcard entries often secure favourable first-round draws against lower-ranked opponents, as seen with Marin Cilic’s 2024 return. The current 47% YES probability for Serena reflects this manageable opener, though past cases like Cilic’s show that even “manageable” matches can slip if fitness or timing falters early in the tournament.

Traders should monitor Williams’ practice court reports and any official updates on her physical readiness, as her eligibility was only recently reinstated by the ITIA. With the settlement window ending 6 July 2026, watch for pre-match announcements confirming her participation and any potential delays, which could trigger the 50-50 resolution clause if the match is not completed within seven days.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
