Lowest temperature in Chicago on Jun 12, 2026?

Prediction market odds reflect real-money trader consensus and often diverge from traditional meteorologist forecasts because markets incorporate a broader set of information and incentivize accuracy through financial stakes.

Comparing the two reveals whether the market is pricing in more extreme outcomes than official forecasts suggest, or conversely, whether traders are more conservative. Both sources offer value: analysts provide detailed reasoning, while market odds reveal where informed participants are willing to commit capital.
