Analysis

This contract predicts whether the minimum temperature in a specific location will exceed 71°F on April 21, 2026. The 80% probability reflects the current market consensus that such a temperature is likely, with the leading outcome (78-79°F) priced substantially higher than alternatives. The probability is driven by typical seasonal patterns for late April, regional climate patterns, and historical weather variability for that date and location. The resolution will occur on April 21, 2026, when actual minimum temperature readings are recorded and compared against the contract thresholds. Traders are effectively betting on whether April 21 conditions will fall into the warm range (78-79°F) rather than cooler alternatives (71°F or below, 76-77°F) or unusually warm (80°F+). The contract reflects confidence in above-normal temperatures for that spring date.

  • Seasonal baseline: Late April typically experiences warming trends in most temperate zones, establishing a natural floor above 71°F
  • Market concentration: 80% of contract value flows to the 78-79°F outcome, indicating strong consensus on a specific narrow range rather than broader confidence in >71°F
  • Weather volatility tail risk: Spring weather patterns retain significant uncertainty; unexpected cold fronts or atmospheric anomalies could drive actual temperatures below predicted ranges
  • Historical frequency data: Local climate records for April 21 over 30+ years would show how often minimum temperatures fall into each contract band
  • Current date context: As of June 14, 2026, this contract appears misdated or references a past event; resolution mechanics depend on whether readings are historical or forecasted

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.
