Analysis

This probability reflects market expectations that 2026 will produce at least three Atlantic hurricanes reaching major (Category 3+) intensity. The 85% confidence level sits well above historical averages, driven by Atlantic sea surface temperatures and atmospheric conditions entering the season. The related contracts show meaningful uncertainty at the extremes: only 42% probability for four-plus major hurricanes and 16% for six-plus, suggesting consensus around a moderately active season rather than an exceptional one. The Atlantic hurricane season runs June through November, with peak activity typically in August-September. The National Hurricane Center's official seasonal forecast, released in early June, will provide the first major update to current market pricing and incorporate the latest climate model data.

  • Atlantic sea surface temperatures relative to climatological baseline during boreal summer 2026
  • Atlantic Meridional Overturning Circulation (AMOC) strength and warm-water anomalies in development zones
  • El Niño / La Niña / neutral ENSO conditions, which suppress or enhance Atlantic hurricane formation
  • Saharan dust patterns and African tropical wave genesis frequency during peak season months
  • Actual storm track and intensity data from June-November 2026 will steadily resolve uncertainty toward season end

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
