Kalshi
This event tracks the minimum temperature recorded in Philadelphia on June 9, 2026, according to the National Weather Service's official Climatological Report. The outcome will be determined by the actual temperature reading from that date in Philadelphia.
Prediction market odds on Kalshi reflect aggregated trader expectations, which often differ from traditional weather analyst forecasts. While meteorologists rely on deterministic models and historical patterns, prediction markets incorporate real-time information and trader conviction through financial incentives. Comparing Kalshi odds to National Weather Service or private meteorology forecasts can reveal where the crowd sees risk differently. Markets may price in tail risks or unusual scenarios that analysts downplay, or vice versa, making the comparison valuable for understanding consensus versus outlier views on Philadelphia's June 9 low temperature.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, this event is priced through binary or range-based contracts tied to specific temperature thresholds for Philadelphia's low on June 9, 2026. Traders buy and sell shares reflecting their belief in whether the actual low will fall within or outside defined ranges. Prices move between 0 and 100 cents per share, with higher prices indicating stronger market confidence in an outcome. The contract design isolates temperature risk, allowing traders to express precise views on whether conditions will be unusually cold, typical, or warm for early June in Philadelphia.
The market resolves on Jun 10, 2026, after the close of trading on June 9, 2026. Resolution is determined by the official lowest temperature recorded in Philadelphia on that date. The outcome is typically sourced from authoritative weather data providers such as the National Weather Service or equivalent official meteorological records. Once the actual low temperature is confirmed and published, the contract settles based on whether it matches the specified outcome criteria, and traders receive payouts accordingly.
Several factors could shift odds before June 9, 2026. Major weather pattern changes—such as an unexpected cold front, high-pressure system, or tropical system—would alter temperature expectations significantly. Seasonal climate anomalies, El Niño or La Niña shifts, and long-range forecast updates from meteorological agencies can influence trader positioning. As the event date approaches, short-range model consensus typically tightens, reducing uncertainty and stabilizing prices. Real-time atmospheric data, jet stream positioning, and any unusual solar or volcanic activity could also move the market. Traders monitor all available weather intelligence to adjust their positions.
