This market tracks the lowest temperature recorded in Denver on June 16, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Denver, CO, which measures the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at Denver, CO on June 16, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS website under the Boulder forecast office, Observed Weather section. Temperature ranges are divided into six bands: below 50°F, 50-51°F, 52-53°F, 54-55°F, 56-57°F, and above 57°F. Each band corresponds to a distinct market outcome. Preliminary NWS data may contain rounding and conversion nuances, so traders should rely on the final published daily climatological report rather than real-time or third-party weather services. The latest version of the data for the specified date should be used for resolution.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares tied to specific temperature thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each contract represents a binary outcome—for example, whether the minimum temperature will exceed 57 degrees—and the market price reflects the last matched trade. As new information emerges or trader conviction shifts, the odds adjust in real time. Higher trading volume typically narrows spreads and increases price accuracy, making active markets more reliable indicators of true probability.
This market resolves around Jun 17, 2026, once June 16, 2026 has passed and the actual lowest temperature in Denver is verifiable from credible public sources. The outcome is determined by comparing recorded weather data against the specific temperature thresholds embedded in each contract. Traders who correctly predicted the temperature range receive their winnings, while incorrect positions expire worthless. Resolution typically occurs within hours of the event, allowing quick settlement and payout.
Several factors could shift odds significantly before resolution. Updated seasonal climate forecasts, El Niño or La Niña patterns, and long-range weather models may prompt traders to adjust positions. Breaking news about atmospheric conditions or unexpected cold fronts could trigger sharp price movements. As June 16 approaches, near-term weather forecasts become more reliable and may cause rapid repricing. Major trader entries or exits can also move the market, especially if volume remains modest. Monitoring meteorological updates and tracking order-book depth helps traders anticipate these shifts.
