These ten prediction markets track the highest temperature expected in San Francisco on May 19, 2026, broken down into specific temperature bands. Rather than predicting a single number, market participants here express their expectations by taking positions across multiple overlapping ranges—each band representing a two-degree window from 48°F to 59°F. This granular approach reveals not just whether the market expects warmer or cooler weather, but also the level of confidence around specific outcomes. By examining the probability distribution across all bands, you can see whether the market consensus clusters around a particular temperature range or remains distributed across multiple scenarios. Markets like these aggregate dispersed information from weather data, seasonal patterns, and participant expertise into real-time price signals. The prices you see below reflect the collective assessment of thousands of participants who have analyzed available meteorological information. Higher prices indicate greater market confidence in those specific outcomes, while lower prices suggest skepticism. If probabilities across adjacent bands show a clear progression—for example, steadily increasing from 48°F to 54°F before declining—that suggests the market has settled on a likely range. Conversely, if probabilities are relatively flat across the spectrum, it indicates genuine uncertainty about which band will verify. These markets update continuously as new weather forecasts emerge and participants reassess their expectations. For weather-sensitive industries, event planners, and anyone with a vested interest in San Francisco's conditions that day, tracking these price movements offers insight into what informed participants collectively expect to occur.
