Analysis

4d ago

This market shows extreme illiquidity with zero 24-hour volume and only $568 in open interest, making the 2394.6% implied yield on the Yes side largely theoretical rather than actionable. The 4¢ spread is wide relative to the 11¢ price, and the Cliff Risk Index of 9 suggests significant tail risk around the September 2026 expiration—likely driven by uncertainty about whether Anthropic will pursue public markets within this 137-day window. The stagnant 7-day price action (flat at 10¢) combined with neutral regime conditions indicates minimal conviction among traders, suggesting this contract may be better suited for sentiment tracking than serious capital deployment.

Resolution rules

If Anthropic confirms an IPO before Sep 1, 2026, then the market resolves to Yes.
