3 prediction markets price this story:

• Before Oct 15, 2026 — resolved “Yes” on 13 Oct 2026. The market resolves to Yes if a hurricane with winds of at least 74 mph forms in the Atlantic Ocean before October 15, 2026. It resolves to No if no such storm develops in that region by the deadline. Readers often mistake the linked story about Mexico's Pacific Coast for the relevant event, but only storms in the Atlantic count.
• Will there be 1-3 hurricanes during the Atlantic Hurricane Season in 2026? — the market puts it at 98%, closing 1 Dec 2026. The market resolves to Yes if 1 to 3 Atlantic storms reach hurricane status between now and November 30, 2026, at 11:59 PM ET. It resolves to No if fewer than 1 or more than 3 hurricanes occur in that period. Readers often mistake the deadline as the end of the calendar year rather than the specific date and time listed.
• Category 4 or above — resolved “No” on 12 Oct 2026. The market resolves to Yes if Hurricane Isaias reaches maximum sustained winds of 130 mph or higher. It resolves to No if it does not reach that wind speed threshold.
