Analysis
This market is pricing in an extremely low probability (6%) for Deep Fission to achieve criticality within 106 days, yet the Yes-side implied yield of 6,531% signals severe illiquidity and potential mispricing rather than genuine confidence in the outcome. The $2,730 open interest with zero 24-hour volume and a 1¢ spread suggests minimal market participation, making the extreme yield figure unreliable as a true probability signal. With a Cliff Risk Index of 19 and only ~3.5 months to resolution, this appears to be a thin, speculative market where even small position sizes could generate outsized percentage returns, but traders should be cautious about the lack of depth and execution risk.
Resolution rules
If Deep Fission achieves criticality before Aug 1, 2026, then the market resolves to Yes.
