On May 18, 2026, Seattle's highest temperature will be recorded and settled against these prediction markets. The eight markets grouped here each represent a different temperature range—from 39°F or below up through 50–51°F—allowing you to see at a glance what outcome the prediction market participants expect most likely. These markets are interrelated: exactly one outcome will occur when the temperature is recorded, and the market prices across all eight options will reflect the collective assessment of where the thermometer will rise to on that day. When you examine the prices below, keep in mind that a higher market price indicates traders see that outcome as more probable. For example, if the 50–51°F market shows a price of 35¢ while the 42–43°F market shows 22¢, it suggests market participants believe the high will reach the 50s rather than the low 40s. The sum of all eight prices should approach $1, since exactly one will resolve to yes and the others to no. Any deviation below $1 usually reflects the liquidity or activity in the market at that moment. These prices update in real-time based on new information—news about high-pressure systems, ocean currents, or seasonal patterns—so returning to this page over the next few days will show you how expectations shift as May 18 approaches. For traders interested in weather-based forecasting or simply curious how probability markets price uncertain natural events, this Seattle temperature range market serves as an educational example of price discovery in action.
