2 prediction markets price this story:

  • Hanna — resolved “No” on 8 Oct 2026. The market resolves to Yes if a storm named Hanna becomes the first hurricane in the Atlantic between May 15, 2026, and December 1, 2026. It resolves to No if no such storm occurs or another storm reaches hurricane status first. Readers often mistake the formation of Tropical Storm Hanna for the resolution condition, but the storm must officially be categorized as a hurricane.
  • Will the name of the first hurricane in the Atlantic for the 2026 Hurricane Season be Hanna? — resolved “No” on 8 Oct 2026. The "Yes" outcome occurs if the first Atlantic storm to reach Category 1 hurricane status (winds of 74 mph or higher) is named Hanna before November 30, 2026. The "No" outcome applies if that first hurricane has a different name or if no hurricanes form in the Atlantic during the period.

Odds are the market's probability that the outcome happens, updated every few minutes. They are information about what traders expect, not a forecast we make and not investment advice.
