Analysis

AI-generated · updated daily

This market is pricing April rain in Austin at an extremely high 88% probability with just 13 days to expiry, yet the extraordinarily skewed yield structure (491% for Yes vs. 15,766% for No) suggests severe mispricing or illiquidity concerns given the modest $2,372 open interest. The realized volatility of 105,617% and cliff risk index of 6 indicate this contract exhibits unstable pricing dynamics typical of thin markets, while the recent 5-cent price climb from 83¢ to 85¢ may reflect late positioning ahead of resolution rather than fundamental information arrival.

Resolution rules

If the total precipitation at CLIAUS in Austin in Apr 2026 is strictly greater than 3 inches, then the market resolves to Yes.
