About This Event
In 2026 If the NOAA's National Hurricane Center records more than X hurricanes of hurricane category 1 or above between January 1, 2026 and December 01, 2026, then the market resolves to Yes. The market will expire at the sooner of the occurrence of the event, or one day after December 01, 2026. The market will expire at the sooner of the occurrence of the event, or one day after December 01, 2026.
Current Market Outlook
Kalshi traders are pricing a 64% chance that 2026 will produce more than 4 Atlantic hurricanes. That is a moderate confidence bet, meaning the market sees above-average hurricane activity as the baseline expectation, but not a slam dunk. For context, the 1991-2020 average is 14 named storms and 7 hurricanes per season. A threshold of 5 hurricanes is well below the historical average, which is why the market leans yes.
Key Factors Driving the Odds
The primary factor is the current state of ENSO. The Pacific is transitioning from El Niño to neutral conditions, with La Niña possible by late 2025. La Niña reduces wind shear over the Atlantic, which typically fuels more hurricanes. The 2024 season, which ran during a weak La Niña, produced 18 named storms and 11 hurricanes, well above the 5-hurricane threshold.
Second, Atlantic sea surface temperatures remain elevated. The 2023-2024 anomaly of 1-2 degrees Fahrenheit above the 1991-2020 average has not fully dissipated. Warmer water provides more fuel for tropical cyclones, and the heat content in the Atlantic main development region is still running high.
Third, there is a statistical baseline. Since 2010, only three seasons (2013, 2014, 2022) have had 4 or fewer hurricanes. The last 10 seasons averaged 8.2 hurricanes. The market is essentially pricing in that a 5-hurricane season is a low bar, and the current climate regime makes a quiet season less likely.
What Could Change These Odds
The biggest risk is a rapid shift to El Niño conditions before summer 2026. El Niño increases Atlantic wind shear and suppresses hurricane formation. If the ENSO forecast flips, expect the odds to drop toward 50%.
Another risk is a quiet early season. The Atlantic typically sees 2-3 hurricanes by September 1. If August 2026 passes with zero hurricanes, the probability will fall sharply, as the season would need to produce 5 hurricanes in three months. That is possible but historically rare.
The key date to watch is the NOAA seasonal outlook, usually released in late May 2026. That forecast will incorporate the latest ENSO and SST data, and the market will react to it.

Overview
This prediction market concerns the total number of Atlantic hurricanes (category 1 or higher on the Saffir-Simpson scale) recorded by the National Hurricane Center (NHC) between January 1, 2026 and December 1, 2026. Hurricanes are tropical cyclones with sustained winds of at least 74 mph. The market resolves to Yes if the count exceeds a specific threshold X, which is set by the market creator. This type of market allows participants to bet on seasonal hurricane activity, which has significant implications for insurance, energy, and emergency management sectors.
Historical Context
The Atlantic hurricane season officially runs from June 1 to November 30, with most activity occurring between August and October. The NHC has recorded hurricanes since 1851, but reliable satellite-era records began in 1966. The 30-year average (1991-2020) is 14 named storms, 7 hurricanes, and 3 major hurricanes (category 3+). However, individual years vary dramatically. 2020 saw a record 30 named storms and 14 hurricanes, while 1983 had only 4 named storms and 3 hurricanes. El Niño years tend to suppress Atlantic hurricane formation due to increased wind shear, while La Niña years enhance activity. Climate change is expected to increase the proportion of intense hurricanes, though the total number may not rise significantly. The most active season on record for hurricanes is 2020 with 14, while 2005 had 15 hurricanes. The 2023 season had 20 named storms and 7 hurricanes, slightly above average.
Why It Matters
Hurricane frequency directly impacts the insurance and reinsurance industries, which face billions in claims each year. A single active season can cause $50-$100 billion in damages, as seen in 2017 (Hurricanes Harvey, Irma, Maria) and 2022 (Hurricane Ian). Insurers raise premiums or withdraw from high-risk areas like Florida and the Gulf Coast after bad seasons. Energy markets also react: hurricanes can shut down 40-60% of Gulf of Mexico oil production, spiking gasoline and natural gas prices. The 2021 Hurricane Ida caused widespread power outages and refinery closures. For coastal communities, each hurricane brings risk of storm surge, flooding, and wind damage. Emergency management agencies use seasonal forecasts to pre-position supplies and personnel. The prediction market provides a real-time, aggregated view of expected activity, which can inform hedging strategies for commodities and catastrophe bonds.
Current Status
As of early 2026, the Atlantic hurricane season has not yet begun. The 2025 season ended with 12 named storms and 6 hurricanes, below the 30-year average. NOAA's Climate Prediction Center will issue its first 2026 outlook in May 2026. Current conditions show a weak La Niña in the Pacific, which typically favors above-average Atlantic hurricane activity. Sea surface temperatures in the Atlantic Main Development Region remain above normal, providing more fuel for storms. The market will resolve based on NHC records from January 1 to December 1, 2026.
Frequently Asked Questions
How does NOAA define a hurricane?
A hurricane is a tropical cyclone with maximum sustained winds of 74 mph (119 km/h) or higher. The NHC uses the Saffir-Simpson scale, with Category 1 starting at 74 mph and Category 5 at 157 mph.
What factors influence the number of Atlantic hurricanes each year?
Key factors include sea surface temperatures, El Niño/La Niña conditions, wind shear, African easterly waves, and the Atlantic Multidecadal Oscillation (AMO). Warmer water and low wind shear increase hurricane formation.
When does the Atlantic hurricane season start and end?
The official season runs from June 1 to November 30. However, storms can form outside these dates; for example, Hurricane Alex formed in January 2016. The market covers January 1 to December 1.
What is the difference between a named storm and a hurricane?
A named storm is a tropical storm with winds of 39-73 mph. It becomes a hurricane when winds reach 74 mph. The market counts only hurricanes (category 1 and above), not all named storms.
How accurate are seasonal hurricane forecasts?
NOAA and CSU forecasts have improved but can miss by 2-4 storms. The 2020 season was underpredicted by 10 named storms. Forecasts are more reliable for overall activity than for landfall locations.
What happens if a hurricane forms in December?
The market expires on December 1, 2026, so storms after that date are not counted. Late-season hurricanes are rare but possible; for instance, Hurricane Epsilon formed in October 2020.
