Analysis
This market prices Medvedev at just 3% to hold the #1 ranking in 259 days, implying an extraordinary 4560% annualized yield for YES holders—an extreme outlier reflecting either deep skepticism about his ability to maintain or reclaim the top spot, or severe illiquidity with only $691 open interest and zero 24-hour volume. The 1¢ spread and neutral regime score suggest pricing uncertainty rather than conviction, and the 32 Cliff Risk Index indicates meaningful tail risk, likely from Medvedev's current ranking position and the competitive ATP landscape. At 3¢, this appears mispriced relative to his historical ranking volatility and the two-year timeframe, though the zero volume warns that liquidity constraints may prevent efficient arbitrage.
Resolution rules
If Daniil Medvedev is the #1 ranked on the PIF ATP singles rankings on Dec 31, 2026 at 12:00 PM ET, then the market resolves to Yes.
