Kalshi
This market tracks whether the overnight low temperature in Washington DC on May 29, 2026, will exceed 56 degrees Fahrenheit. On Kalshi, the leading outcome—a minimum above 56°—stands at 49.0%, while a minimum between 55–56° carries 40.0% probability. Resolution will be determined by the National Weather Service's Climatological Report for that date. Watch the National Weather Service's daily temperature recordings as May 29, 2026, approaches to gauge whether seasonal warming patterns will push overnight lows above the threshold.
Prediction market odds on Kalshi reflect real-money consensus from traders betting on the lowest temperature in Washington DC on May 29, 2026. Unlike traditional weather analyst forecasts, which rely on deterministic models and historical climatology, prediction markets incorporate forward-looking trader expectations and incentivize accuracy through financial stakes. Comparing Kalshi odds to seasonal climate outlooks from NOAA or The Weather Company reveals whether traders are pricing in above-normal cold, near-normal conditions, or warmer-than-average temperatures. Market-implied probabilities often diverge from model consensus when traders have access to emerging atmospheric signals or long-range pattern shifts.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, the lowest temperature in Washington DC on May 29, 2026, is priced through binary or range-based outcome contracts that divide the possible temperature range into discrete buckets. Traders buy and sell shares corresponding to each temperature threshold, with prices reflecting the collective probability assigned to that outcome. As new weather data, seasonal patterns, or atmospheric models emerge, share prices adjust to reflect updated trader conviction. The market price directly translates to an implied probability, allowing you to see at a glance whether the crowd expects an unusually cold morning, typical late-May conditions, or above-normal warmth for that specific date in DC.
The market resolves on May 30, 2026, after the lowest temperature in Washington DC on May 29, 2026, has been recorded and verified. Resolution occurs once official temperature data for that date becomes available and is confirmed against the designated reference source. Traders holding shares in the correct outcome receive their payout, while incorrect positions expire worthless. The timing ensures that all intraday temperature readings for May 29 are captured before settlement, eliminating ambiguity about which low-temperature value applies to that calendar day.
Several factors could shift odds for the lowest temperature in Washington DC on May 29, 2026. Long-range weather pattern updates from the Climate Prediction Center or European model ensembles may signal whether a cold front or high-pressure system will dominate the region that week. Seasonal climate indices, such as the North Atlantic Oscillation or Pacific patterns, influence late-May temperatures across the eastern United States. As May 2026 approaches, medium-range forecasts become more precise, allowing traders to refine their bets. Urban heat island effects, recent spring warmth or cold snaps, and any unusual atmospheric blocking patterns will also influence market pricing as the event date draws nearer.
