Kalshi
The overnight low temperature in Boston on June 6, 2026, will be recorded by the National Weather Service.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, the lowest temperature in Boston on June 6, 2026 is priced as a set of binary or range-based contracts, each representing a specific temperature threshold or band. Traders buy or sell shares at prices between 0 and 100 cents, where the price reflects the implied probability of that outcome occurring. As new information emerges—seasonal forecasts, climate patterns, or real-time weather data—traders adjust positions, moving prices up or down. The contract that resolves to 100 cents (or the correct temperature band) pays out fully, while others expire worthless, creating direct financial incentives for accurate pricing.
The market resolves on Jun 7, 2026, after June 6, 2026 has concluded and the lowest temperature in Boston for that day is officially recorded. Resolution is determined by verified historical temperature data for Boston on that specific date. The outcome is typically sourced from a recognized meteorological authority to ensure accuracy and prevent disputes. Once the official low temperature is confirmed, the corresponding contract outcome is determined, and payouts are distributed to winning traders. This timing allows sufficient time for data verification before final settlement.
Several factors could shift market odds for Boston's June 6 low temperature. Long-range seasonal forecasts and climate pattern updates from meteorological agencies will influence trader expectations as the date approaches. Major weather systems—cold fronts, high-pressure systems, or unusual jet-stream behavior—visible in extended forecasts could trigger significant price moves. Historical climate data and typical June weather patterns for Boston also inform pricing. As June 2026 draws closer, short-range forecasts become more reliable, typically causing sharper market adjustments. Real-time atmospheric conditions in the days leading up to June 6 will be the most influential factor in final pricing.
