Across Polymarket and Kalshi, the consensus probability that global temperature will increase between 1.20°C and 1.24°C stands at 69.0%. Resolution will be determined by NASA's official Global Land-Ocean Temperature Index data for June 2026, expected to be released by mid-July 2026. Watch for NASA's publication of the June 2026 temperature anomaly data, scheduled for release by August 1, 2026, which will immediately settle this market.
This market will resolve according to the value reported by the Global Land-Ocean Temperature Index for June 2026 when it is released. An anomaly within a named bracket for June 2026 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for June 2026 is later revised. The primary resolution source for this market will be the figure found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Jun" in the row "2026" (https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt). If NASA’s “Global Temperature Index” is rendered permanently unavailable, other information from NASA may be used. If no information for June 2026 is provided by NASA by August 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.
Each outcome resolves to Yes if the Land Ocean-Temperature Index for June 2026 falls within the specified range. The six outcomes cover consecutive temperature bands: below 1.03, 1.03–1.09, 1.10–1.16, 1.17–1.23, 1.24–1.30, and above 1.30, allowing traders to bet on the magnitude of temperature anomaly for that month.
Prediction market prices reflect real-money consensus from thousands of traders and differ from traditional climate model forecasts. While meteorological agencies issue deterministic projections based on atmospheric physics, prediction markets incorporate uncertainty, geopolitical risk, and market sentiment. The June 2026 event allows direct comparison: if markets price lower temperature increases than climate models suggest, it may signal trader skepticism about model accuracy or expectations of cooling events. Conversely, higher market prices could reflect tail-risk concerns absent from baseline forecasts.
The June 2026 Temperature Increase market resolves on Jul 17, 2026. Resolution depends on official global temperature anomaly data released after the month concludes, typically from established climate monitoring agencies. The exact measurement methodology—whether using satellite data, surface station networks, or blended indices—determines which outcomes settle in-the-money. Traders should monitor announcements from relevant authorities as June ends to understand how the final temperature increase will be calculated and which prediction market outcomes will be deemed correct.
Major catalysts include updated climate forecasts, El Niño or La Niña transitions, volcanic activity, and solar cycle changes. Unexpected weather patterns or atmospheric anomalies reported in early 2026 will shift market expectations. Policy announcements affecting emissions or geoengineering could also influence prices. As June approaches, preliminary monthly temperature data and real-time weather developments will drive volatility. Scientific publications revising climate sensitivity estimates or new satellite measurements may trigger repricing. Traders should track meteorological agencies, climate research releases, and geophysical events throughout the prediction window.
