This market tracks the highest temperature recorded in Atlanta on June 22, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with resolution based on specific temperature ranges.
Resolution is determined by the maximum temperature recorded at Atlanta on June 22, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Climate portal for Atlanta, GA. Temperature ranges are divided into six bands: 85°F or below, 86-87°F, 88-89°F, 90-91°F, 92-93°F, and 94°F or above. Each range corresponds to a distinct market outcome. Traders should note that preliminary NWS reporting may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather data sources.
Prediction market odds reflect aggregated trader expectations and often incorporate meteorological models, historical temperature patterns, and climate data faster than traditional analyst consensus. While weather forecasters typically issue point estimates or ranges based on atmospheric modeling, this market prices uncertainty through continuous trading. Comparing the implied probability from market odds to published seasonal forecasts for Atlanta in late June can reveal whether traders are pricing in more or less extreme heat than official predictions suggest.
On Kalshi, this market is priced through a continuous order book where traders buy and sell shares representing different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each contract reflects a specific temperature range or threshold, and the market price—expressed as a percentage—represents the collective probability assigned by active traders. As new information arrives, bids and asks adjust, causing the price to move and allowing participants to enter or exit positions at prevailing rates.
This market resolves around Jun 23, 2026, once June 22, 2026 has passed and the highest temperature recorded in Atlanta that day is verified. The outcome is confirmed against credible public sources that document official weather observations. Traders holding positions aligned with the verified temperature will receive payouts based on the final settlement price.
Major weather pattern shifts, updated seasonal climate forecasts, and long-range atmospheric models can significantly influence trading activity. El Niño or La Niña conditions, jet stream positioning, and historical heat wave patterns for early summer in the Southeast all serve as key catalysts. Additionally, any revision to climate normals or emerging data on urban heat island effects in Atlanta may prompt traders to reassess their positions and adjust market prices.
