Analysis

This market asks whether any single month in 2026 will record higher average temperatures than any month in instrumental history. The 32% probability reflects significant uncertainty about whether 2026 will exceed records set in recent years, particularly 2023 and 2024. Temperature trends depend primarily on seasonal patterns, El Niño/La Niña conditions, and underlying climate warming. Current probability reflects disagreement between venues, with Polymarket pricing substantially higher. The main resolution driver is the monthly global temperature data releases from agencies like NOAA and Copernicus throughout 2026, with particular attention to Northern Hemisphere summer months (June-August) when records are most frequently set. December's final data confirmation typically occurs in January 2027.

  • Recent monthly records were set in 2023-2024; beating these requires either exceptional conditions or measurement of a sustained warming trend
  • Tropical Pacific conditions (El Niño/La Niña phase) significantly influence global temperature anomalies; current forecasts through 2026 will inform probability revisions
  • Northern Hemisphere summer months (June-August) historically see the largest monthly temperature anomalies and represent the highest-probability window for record-breaking
  • Monthly temperature releases from NOAA, Copernicus, and JMA provide the definitive data; each monthly release from May 2026 onward will resolve partial uncertainty
  • The gap between Kalshi (29%) and Polymarket (80%) suggests markets disagree on climate trend momentum and record-beating likelihood rather than factual disagreement

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 1 contract (85% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

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.
