The market resolves on Jun 7, 2026, after the lowest temperature for Philadelphia on June 6, 2026 has been recorded and verified. Resolution depends on official temperature data from a designated meteorological source, typically the National Weather Service or equivalent weather station serving the Philadelphia area. The exact temperature reading on that date determines which outcome bracket or threshold is correct, and traders holding the winning contract receive their payout. Early closure or data disputes are rare but possible if severe weather or measurement issues arise.
Major signals include updated seasonal forecasts, atmospheric pattern shifts, and long-range weather models issued by NOAA and international meteorological centers. A developing El Niño or La Niña phase, polar vortex anomalies, or jet stream positioning in early June could push temperatures warmer or cooler than climatological norms. Real-time weather alerts, heat waves or cold snaps in the preceding weeks, and changes in solar activity may also influence trader positioning. As June 6 approaches, short-range forecasts become more precise, typically causing sharper odds adjustments in the final days before resolution.
