Analysis

This probability reflects the chance that the maximum temperature will fall within the 63-64°F range on April 21, 2026 at a specified location. The current 38% level suggests this outcome is considered less likely than alternatives, possibly because late April weather typically produces higher temperatures or because historical patterns for that date favor different ranges. The main drivers are seasonal temperature norms for late spring and any emerging climate patterns that might shift April conditions warmer or cooler than average. The resolution will occur on April 21, 2026, when actual maximum temperature data becomes available. Until then, the probability may shift if longer-range forecasts are issued or if patterns similar to the target date emerge in preceding weeks.

  • Historical maximum temperatures for April 21 at the target location compared to the 63-64°F range
  • Seasonal warming trajectory in late April relative to earlier spring months
  • Current market pricing across four contracts suggests the 63-64°F band ranks third or fourth among competing outcomes
  • Distance to resolution date (approximately 10.5 months away) limits availability of actionable weather forecasts
  • Runner-up contract at 31% indicates at least one competing temperature range is viewed as notably more probable

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.
