Analysis
This market is pricing in an extremely high probability (93%) that Anthropic will have the top-ranked LLM by April 25, 2026, with only 6 days to expiry, yet the implied yield on a "No" outcome reaches an absurd 83,206%—a clear sign of severe illiquidity and extreme tail risk pricing rather than genuine market consensus. The 7-cent price appreciation over one week combined with a realized volatility of 398% and cliff risk index of 13 suggests this contract has experienced sharp moves near expiration, and the tight 1¢ spread masks the underlying fragility given the $18.9K volume is barely above open interest. With 2.1 information arrivals per hour and only days remaining, any new AI benchmark results or model release could trigger a dramatic repricing, making the "No" side a potentially lucrative but highly speculative bet despite its punitive odds.
Resolution rules
If Anthropic has the top-ranked LLM on Apr 25, 2026, then the market resolves to Yes.
