During 2026, the Atlantic hurricane season will produce various hurricanes that meet or exceed Category 1 intensity as monitored by the National Hurricane Center.
Resolution is based on the count of Atlantic tropical storms recorded by NOAA's National Hurricane Center between January 1, 2026 and December 1, 2026, where tropical storms are defined as systems with maximum sustained wind speeds of 39 miles per hour or above. The market resolves Yes if the total exceeds any of the specified thresholds: 10, 12, 14, 16, 18, 20, 25, or 30 storms. Each threshold represents a separate resolution condition, with higher thresholds indicating more active storm seasons. The market expires at the sooner of the event occurrence or one day after December 1, 2026.
On Kalshi, this market is priced using a continuous double auction, meaning buyers and sellers set the prices for contracts representing different outcomes. Traders are incentivized to offer prices that accurately reflect their beliefs about the likelihood of each scenario. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of a contract represents the probability of that outcome occurring, with higher prices indicating greater perceived likelihood. As more trades occur, the market price converges towards a consensus view. This dynamic pricing mechanism allows for a fluid and responsive assessment of the potential for an active Atlantic hurricane season.
This market resolves around Dec 2, 2026, with the outcome confirmed once the final count of named tropical storms in the Atlantic basin during the 2026 season is verifiable from credible public reporting. The National Hurricane Center (NHC) is the primary source for official storm data, and their reports will be used to determine the number of storms that occurred. The resolution will be based on the official NHC storm reports, ensuring a transparent and objective determination of the final result for this market.
Several factors could significantly influence this market between now and resolution. Early seasonal forecasts released in the spring of 2026 will likely cause price adjustments. The development of El Niño or La Niña conditions in the Pacific Ocean, which strongly influence Atlantic hurricane activity, will be a key driver. Unexpected changes in sea surface temperatures in the Atlantic, particularly in the Main Development Region, could also shift the market. Finally, any major advancements in hurricane forecasting technology or changes in climate patterns could impact traders’ assessments and move this market.
