Analysis
The market prices Sabalenka's chances of winning a Grand Slam in 2026 at 73%, reflecting her status as a top-ranked player with two Australian Open titles already, though the extremely asymmetric implied yields (52.3% for Yes vs. 382.3% for No) suggest the No side offers substantially better risk-adjusted returns at 191%. Liquidity is thin with only $3,668 open interest and $216 in 24-hour volume, creating potential execution challenges for larger positions, while the 1¢ spread and stable price movement from 72¢ to 73¢ over seven days indicate a relatively settled market with low conviction shifts despite 258 days remaining until expiry.
Resolution rules
If Aryna Sabalenka wins a tennis major (the Australian Open, the U.S. Open, the French Open, or Wimbledon) before Dec 31, 2026, then the market resolves to Yes.
