Predicting annual tornado counts falls under the category of Weather Derivatives. While it is a serious topic for the insurance and reinsurance industries, it is a relatively niche and specialized subject for the general public and general-purpose prediction markets.

April 9, 2026 - April 12, 2026, the price of '1200-1249' surged from 2.75c to 20.8c, and '1250+' surged from 20c to 31c, likely due to severe spring tornado outbreaks in mid-April, causing the market to significantly revise the expected annual total upwards. March 25, 2026 - March 28, 2026, the price of '950-999' surged from 9.5c to 19.85c, and '1200-1249' surged from 6c to 17c. The reason is a massive influx of irrational speculative buying pushing up 'Yes' prices across the board, causing the total implied probability to severely detach from fundamentals. March 12, 2026 - March 15, 2026, the price of '<950' surged from 10c to 20.5c. The reason is likely the market overreacting to updated forecasts predicting a return of El Niño by summer/fall; traders may be aggressively betting on suppressed late-year activity, ignoring the currently active spring season.

April 18, 2026 05:58 - April 18, 2026 16:48, the 45+ bracket experienced extreme volatility, crashing from 51c to 9c before violently rebounding to 46.5c. This was caused by real-time review additions on Rotten Tomatoes triggering sharp score fluctuations, prompting market panic and subsequent correction over whether the score could hold the 45% threshold. April 16, 2026 - April 17, 2026, prices across all brackets plummeted. For instance, the Yes price for 55+ collapsed from 83c to 22.5c, and 60+ fell from 58c to 11.5c. This was caused by the official review embargo lifting or wider early reactions confirming poor film quality, leading to a complete reversal in market sentiment. April 15, 2026 - April 16, 2026, prices for multiple brackets (e.g., 55+, 60+, 65+, 70+) surged significantly. The Yes price for 55+ rose from 42c to 76c, 60+ jumped from 26.5c to 56c, and 65+ spiked from 25.5c to 58c. This was driven by the review embargo lift or early critic leaks, leading to an overall market upgrade and heavy buying of passing-grade brackets.

April 15, 2026 - April 17, 2026, the price of 'Thrash' surged from 48c to 98.5c, while major competitors like 'Untold: Jail Blazers', 'Jumanji: Welcome to the Jungle', and 'Beast' plummeted from around 25c to under 1c. This is because mid-week Netflix daily charts clearly showed 'Thrash' consistently taking the #1 daily spot, solidifying its victory.
