On May 5, 2026, Guangzhou's high temperature will be a matter of public record, but until that day arrives, the question of what that temperature will be remains open to interpretation. This event aggregator brings together five related prediction markets that all hinge on the same meteorological outcome: the highest temperature recorded in Guangzhou on May 5, 2026. Whether you're a weather enthusiast, a data analyst interested in crowd forecasting, or simply curious about how prediction markets price uncertain events, these markets offer a window into collective intelligence about a concrete, verifiable outcome. The five markets cover temperature points between 16°C and 20°C—a realistic range for Guangzhou in early May—with each market asking a specific question: whether the day's high will be exactly 17°C, 18°C, 19°C, 20°C, or 16°C or below. Because these outcomes are mutually exclusive (the temperature can only have one final value), the prices across all five markets should reflect the combined probability mass assigned to each temperature point. By reading across all five markets, you can see where forecasters believe the temperature distribution is concentrated. If you notice prices that seem inconsistent with one another, that inconsistency itself is valuable information—it may suggest where the crowd sees the greatest uncertainty or where one particular market has attracted different levels of attention. As you explore the prices below, consider what weather patterns are typical for Guangzhou in early May, whether any unusual seasonal factors might influence the forecast, and how distributed prediction markets might capture information that traditional weather models might overlook.
