Australian Open 2027

The 2027 Australian Open is the next major on the tennis calendar, and its boards are listed more than three months early. Kalshi's men's board now marks Carlos Alcaraz at 38.5%, Jannik Sinner at 33.5% and Alexander Zverev at 10.5%, with Felix Auger-Aliassime at 4% and Novak Djokovic at 3.5%. Two weeks ago Sinner led and Zverev was 20%.

Little has traded. Alcaraz's leg took $271 today, more than any other name shown, and the men's board holds $38,910 of open interest. The women's board turned $104.

Read these as opening marks rather than prices.

Left, the men's board: Alcaraz 38.5%, Sinner 33.5%, Zverev 10.5%. Right, the women's board, shown as bars because its marks add to far more than 100%: Elina Svitolina 39%, Marta Kostyuk 37.5%, Sorana Cirstea 28%, Aryna Sabalenka 27% and Elena Rybakina 18%, an order no traded book would hold.

Alcaraz is marked 38.5% on $271 today and Sinner 33.5% on $30. On a long-dated board this thin, read the marks as quotes more than prints; the five-point gap between them is new this month.

Kalshi's 2027 French Open men's board is listed and has not traded: Sinner is marked 45% and Alcaraz 39%, with Zverev at 13%, Djokovic 5.5% and Rafael Jodar 4.5%. The same two names lead both boards, in the opposite order.

Rybakina at 18%, untraded today, and Sabalenka at 27%, on $25. Both are marked below Svitolina, Kostyuk and Cirstea on a board that is listed but not yet made.

• When the boards start trading. A few hundred dollars a day on the men's side and about $100 on the women's, with the tournament in late January.
• Alcaraz against Sinner. 38.5% and 33.5% on thin marks; the order flipped this month.
• Zverev at 10.5%. Down from 20% two weeks ago.
• The women's board. Marks that sum to well over 100% mean it has no price yet. Watch for the order to settle once it trades.
• Settlement. Both Australian Open boards settle February 1, 2027.
