Analysis

5d ago

This market shows extreme mispricing with a 1,878% implied yield on the Yes side, suggesting the 7¢ price significantly undervalues Fernandez's Grand Slam chances over the next 258 days. The zero 24-hour volume and thin $596 open interest indicate severe illiquidity, making the quoted price potentially unreliable and the wide 6¢ spread a warning sign for potential traders. The dramatic 7-week rally from 1¢ to 7¢ combined with the elevated Cliff Risk Index of 13 suggests recent volatility or information flow, though the neutral regime score indicates no clear directional momentum.

Resolution rules

If Leylah Fernandez 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.
