61% — Will there be more than 6  Atlantic hurricanes in 2026
Leader: Above 4 at 61% · Kalshi 61% · 8 contracts · $68 volume · medium confidence

Tracks the leading outcome in a winner-take-all prediction market set with 8 outcomes.

Why this matters:
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.

Key factors:
- 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

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.

## SF Signal

- SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
- No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only.
