Analysis

This contract tracks whether the minimum temperature will fall between 58-59°F on April 22, 2026—a historically cool outcome for late spring. At 39%, the market implies this temperature range is unlikely but plausible. The probability reflects seasonal expectations: April 22 typically sees warmer overnight lows across most US regions, making a 58-59° reading an outlier requiring unusual weather patterns like a strong cold front or arctic air mass. The contract will resolve on April 22, 2026, when actual temperature data is recorded. Market participants are pricing in the base rate for cool spring temperatures while accounting for natural variability—the outcome requires colder-than-typical conditions but remains within seasonal possibility. Volume suggests moderate trader interest in spring weather outcomes.

  • Historical climate data for April 22 shows median low temperatures of 55-62°F depending on geographic region, meaning 58-59° falls near or slightly above normal for many locations
  • Current seasonal forecast models and long-range guidance would indicate whether cold air masses are expected to persist into late April or if warming is anticipated
  • The contract's 39% price implies roughly 1-in-3 odds, reflecting real but not dominant probability—traders view this as unlikely relative to warmer April outcomes but not improbable
  • Resolution depends on official temperature measurement protocols and data source, which must be specified in contract terms to eliminate ambiguity
  • Late-season cold snaps occasionally occur in mid-to-late April across northern regions, but persistence of such patterns into April 22 is relatively uncommon in historical records

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.
