Analysis

This contract asks whether the minimum temperature on May 15, 2026 will fall between 50 and 51 degrees Fahrenheit. At 27% probability, traders view this outcome as unlikely but plausible. The current market structure shows most traders expect May 15 to be warmer—the leading outcome (68-69°) reflects seasonal expectations for mid-May conditions in most US locations. The 50-51° range would require significant deviation from typical spring temperatures. What would move this probability up or down depends primarily on seasonal weather pattern forecasts and any shifts in the underlying climate model data. Resolution occurs on May 15, 2026, when the actual minimum temperature is recorded and the winning contract pays out while others expire worthless.

  • The contract resolves May 15, 2026—this date is set and unchangeable, creating a hard deadline for weather data
  • Market prices across the 6 temperature bins suggest median expectations around 68-71°, placing 50-51° in the lower tail of the distribution
  • A 50-51° minimum in mid-May would require either an unusual cold snap or measurement at a location with cooler baseline conditions
  • Current 27% probability is higher than the 17¢ price on the >71° outcome, indicating asymmetric risk perception across temperature ranges
  • Trading volume concentrates on warmer outcomes (>70°), suggesting fewer active traders betting on the 50-51° scenario

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.
