## About

This market resolves to whichever player wins the 2026 US Open Women's Singles tournament, scheduled for August 23 to September 13, 2026. Each listed player is a separate outcome, and if a player is eliminated the corresponding line resolves No. Polymarket carries most of the volume at roughly $6.9 million, with Kalshi adding around $634,000 and smaller books on Gemini, Limitless, and Polymarket US.

Aryna Sabalenka is the consensus favourite at 23.5%, ahead of Iga Swiatek at 18.0% and Coco Gauff at 13.5%. Behind that top trio, Naomi Osaka sits at 8.5%, Mirra Andreeva at 6.5%, and Jessica Pegula at 6.0%, with the rest of the field priced at 4.5% or lower. The gap between Sabalenka and Swiatek is about 5.5 points, signalling a clear but not overwhelming favourite in a field with several credible contenders.

Cross-platform pricing is broadly aligned at the top, but Polymarket consistently prints the cheapest lines on the leaders: Sabalenka at 20.5% versus 24.0% on Polymarket US, Swiatek at 16.0% versus 19.0% on Gemini, and Gauff at 11.3% versus 14.0% on Gemini. The takeaway: books agree on the pecking order, but Polymarket prices the favourites noticeably lower than Gemini and Polymarket US.
