This market tracks the lowest temperature recorded in Atlanta on June 17, 2026, using official National Weather Service data. The outcome will be determined by the minimum temperature reading from the NWS Climatological Report for that specific date.
Resolution is based on the minimum temperature recorded at Atlanta on June 17, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Atlanta, GA. The official data source is accessed via the NWS Climate portal at the specified URL. Temperature readings are divided into six ranges: 61°F or below, 62–63°F, 64–65°F, 66–67°F, 68–69°F, and 70°F or above. Each range corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather services.
Prediction market odds often diverge from traditional weather analyst forecasts because they reflect real-time trader conviction rather than a single model's output. While meteorologists rely on physics-based simulations and historical data, this market aggregates the distributed knowledge of many participants who have financial incentive to forecast accurately. Analyst models typically issue forecasts weeks or months in advance, whereas prediction market prices update continuously as new information arrives. Over time, markets have shown competitive accuracy against expert consensus, particularly when traders have access to the same underlying data and strong incentives to correct mispricing.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares representing different temperature ranges or outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the collective willingness of buyers and sellers to transact at that level, with spreads tightening as volume increases and liquidity deepens. Kalshi's matching engine ensures transparent price discovery, and you can place limit or market orders to enter or exit positions. Real-time bid-ask spreads show the current cost of immediate execution, while historical price charts reveal how market sentiment has evolved.
This market resolves around Jun 18, 2026, once the lowest temperature recorded in Atlanta on June 17, 2026 is verifiable from credible public sources. The outcome is determined by official weather data, typically from the National Weather Service or equivalent meteorological authority. Once the event date passes and the temperature reading is confirmed, the market settles according to which outcome bracket or range the actual low temperature falls into. Traders holding winning positions receive their payout, while losing positions expire worthless.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts can significantly move this market. El Niño or La Niña conditions, polar vortex behavior, and jet stream positioning all influence June temperatures in Atlanta. As the event date approaches, shorter-range forecasts from the National Weather Service become more reliable and can trigger sharp repricing. Historical temperature records and emerging climate data may also shift trader expectations. Additionally, any unusual atmospheric events or model consensus changes in the months leading up to June 2026 will likely drive trading activity and price adjustments.
