Analysis

This contract measures the probability that the maximum temperature in a specific location will reach 79-80°F on April 21, 2026. At 43%, it reflects modest odds relative to the distribution of temperature outcomes traders expect for that date. The current pricing suggests traders see a meaningful chance of this range occurring, though cooler or warmer outcomes are also weighted substantially in the broader contract set. April weather in most temperate regions exhibits high day-to-day variability, and seasonal forecasts from meteorological services become more reliable only within 2-3 weeks of the target date. The resolution of this contract will depend entirely on the actual reported maximum temperature from the designated weather station on April 21, 2026. Historical temperature patterns, climate normal data, and approaching seasonal conditions will likely narrow uncertainty as the date draws closer.

  • The 43% probability for 79-80°F sits between higher probabilities for 87-88°F (30¢) and 89-90°F (45¢), suggesting traders expect temperatures above this range more likely than below it
  • Historical April 21 temperature records and 30-year normals for the target location directly inform baseline expectations and seasonal patterns
  • Current contract volume ($1,335 in 24-hour volume for the leader) indicates active trading but relatively modest liquidity compared to weather derivatives on major benchmarks
  • The multi-outcome structure means this 79-80°F contract competes against five other temperature bands, with the top outcome (89-90°F) commanding less than half the probability space
  • Uncertainty will collapse sharply only when April 2026 arrives; probabilistic refinement depends on 7-14 day weather forecasts, which gain skill only in early April

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.
