Analysis

This market prices the probability of measurable rainfall exceeding 1 inch in New York City during April 2026 at 5%, indicating traders view significant precipitation as unlikely during that month. April historically receives moderate rainfall in NYC, averaging around 4 inches, but the current low probability suggests traders are pricing in either below-average conditions or a specific dry pattern anticipated for that period. The resolution depends on official precipitation measurements from National Weather Service stations serving the NYC area. Key factors driving this assessment include seasonal weather patterns, ensemble forecasts as the month approaches, and comparison to historical April rainfall distributions. As April 2026 occurs after the current date, actual weather data will ultimately determine the outcome when the month concludes and official measurements are recorded.

  • Historical April precipitation in NYC averages ~4 inches, making a sub-1 inch outcome less common than the 5% probability suggests
  • Current market pricing reflects conditions well before April 2026 arrives; probability will shift substantially as seasonal forecasts update and the month approaches
  • Official NWS precipitation totals from NYC area stations (Central Park gauge is standard) will determine resolution; no ambiguity in measurement once data is recorded
  • The three-contract structure shows heavy concentration in the 1-inch threshold (92¢) versus 2-inch (6¢) and 3-inch (4¢), indicating trader consensus clusters around very dry outcomes
  • Resolution occurs automatically when April 2026 concludes; this represents pure weather forecasting rather than discretionary or event-dependent uncertainty

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (44% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

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.
