Analysis

This contract reflects traders' assessment that the 2026 Atlantic hurricane season will produce at least 7 hurricanes, currently priced at 78% probability. The forecast is informed by historical patterns: the baseline climatological expectation for Atlantic hurricanes is 7-8 per season, and recent decades have seen elevated activity due to warmer ocean temperatures. The probability could shift significantly based on sea-surface temperature anomalies in the tropical Atlantic through summer, the strength of El Niño or La Niña conditions, and early-season storm development. The National Hurricane Center typically issues its official seasonal forecast in late May, which often serves as a reference point for market expectations. Resolution depends entirely on accurate counts from the National Weather Service through the November 30 end of hurricane season.

  • Atlantic sea-surface temperatures from June through August will influence atmospheric instability and hurricane formation rates
  • The development or persistence of El Niño conditions would suppress Atlantic hurricane activity; La Niña would favor increased activity
  • The National Hurricane Center's May 2026 seasonal forecast, releasing the official climatological prediction, typically anchors market expectations
  • Early-season hurricane counts (June-July) provide empirical data that traders use to update probabilities for the full season
  • Wind shear patterns and atmospheric moisture levels during peak season months (August-October) determine whether storm systems can intensify into hurricanes

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.
