Analysis

This question asks whether the maximum temperature in a specific location will reach 88–89°F on June 5, 2026. The 41% probability reflects traders' assessment that this narrow temperature band is more likely than not to occur, with most alternative outcomes scattered across neighboring ranges (86–87°F at 26%, 90–91°F at 16%). Temperature outcomes depend on seasonal weather patterns, atmospheric conditions, and local geography. The resolution will occur on the specified date when the daily maximum is recorded and compared against the contract bounds. Traders are pricing in a warm but not extreme day, with the largest share of probability mass in the 86–91°F zone. Uncertainty remains significant because weather forecasts become less precise beyond 10–14 days, and small shifts in pressure systems or cloud cover can move daily highs by several degrees.

  • The modal outcome (88–89°F) commands only 41% of total probability, meaning 59% of traders favor temperatures outside this band
  • The five contracts together cover a 7-degree range from below 86°F to 92–93°F, with the bulk of volume in the 86–91°F cluster
  • No single alternative outcome exceeds 30%, indicating genuine disagreement about the likely maximum rather than consensus with scattered bets
  • Historical climate data and seasonal norms for the location on June 5 will anchor baseline expectations
  • Trading volume is concentrated in the top two contracts ($409 and $336 per 24h), suggesting active price discovery for the most probable outcomes

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.
