TL;DR
Kalshi’s market indicates a prediction about Chicago’s temperature on July 13, 2026, at 12am EDT. The question is whether it will be above 73.99°F, with details still emerging. This forecast is part of a broader trend of climate and weather prediction markets.
Kalshi’s market prediction indicates a 50/50 probability that Chicago’s temperature will be above 73.99°F at 12am EDT on July 13, 2026. This forecast reflects the current assessment of climate models and market data, with the outcome still uncertain and subject to change as new information emerges.
Kalshi, a regulated trading platform for event-based markets, has launched a prediction market asking whether the temperature in Chicago will exceed 73.99°F at midnight on July 13, 2026. As of now, the market shows a near-even split, indicating uncertainty among traders and climate models about the specific temperature at that time.
Experts note that long-term weather predictions at a specific hour and location are inherently uncertain, especially over a two-year horizon. The market’s current stance does not confirm a temperature but reflects collective expectations based on available climate data and trends, which can be monitored through weather prediction markets.
Kalshi’s prediction is part of a broader effort to use financial markets to gauge long-term weather and climate forecasts, which remain highly variable and subject to change with new data or climate developments.
Implications of Long-Term Weather Market Predictions
This prediction matters because it illustrates how weather and climate forecasts are increasingly being incorporated into financial markets, offering a new way to gauge future conditions. While the specific forecast for July 13, 2026, remains uncertain, the market’s activity signals ongoing interest in long-term climate trends and their potential impacts on cities like Chicago.
Understanding the limits and capabilities of such markets is crucial for policymakers, insurers, and urban planners who rely on climate data for decision-making. The prediction also highlights the inherent uncertainties in projecting specific weather conditions years into the future.

Long-Term Climate Prediction Efforts and Market Tools
Forecasting weather months or years in advance involves complex climate models with significant uncertainty. Traditional meteorological predictions typically cover days to weeks, while long-term predictions often focus on seasonal or annual trends.
Kalshi’s market for Chicago’s temperature on July 13, 2026, is part of a growing trend of using prediction markets to assess long-term climate conditions. These markets aggregate diverse data sources and trader expectations, providing a probabilistic view of future events.
Currently, climate scientists emphasize that specific hourly temperature predictions two years ahead are highly uncertain, and market data should be interpreted as indicative rather than definitive.
“Prediction markets like ours provide a unique, aggregated perspective on long-term climate expectations, but they are inherently probabilistic and subject to change.”

Limitations and Uncertainties in Long-Term Temperature Forecasts
It is not yet clear how accurately the prediction market will reflect actual conditions on July 13, 2026. The inherent unpredictability of weather, especially at specific hours and locations years in advance, makes the forecast highly uncertain. Climate models and market data can shift as new information and technology become available.
Furthermore, the current market sentiment does not guarantee the outcome; it merely reflects collective expectations based on current data, which may change significantly before the date in question.

Key Questions
How reliable are long-term weather predictions?
Long-term weather predictions, especially at specific hours and locations, are inherently uncertain. They are more reliable for seasonal or annual trends than for exact conditions at a specific time two years ahead.
What does the prediction market indicate about Chicago’s climate in 2026?
Currently, the market shows a near 50/50 split on whether the temperature will be above 73.99°F at midnight on July 13, 2026, indicating high uncertainty and no clear consensus.
Can prediction markets be used for climate planning?
Prediction markets can provide useful probabilistic insights, but their results should be combined with scientific climate data and used cautiously for long-term planning and decision-making.
Will the temperature definitely be above 73.99°F on that date?
No, it is not yet confirmed. The market reflects expectations, but actual conditions will depend on evolving climate factors and data over the next two years.
