The 68-69°F band holds a 59.5% implied probability for the overnight low, and that number jumped nearly 39 points in the last 24 hours. That kind of momentum does not appear without a reason: observed temperatures heading into this morning confirmed a warm, humid air mass sitting over the metro area, consistent with a typical late-June pattern. The market question asks: what will be the lowest temperature in NYC on June 22? The 68-69°F outcome is priced at $0.60 YES and $0.41 NO. This market resolves at noon on June 22, 2026. Total volume stands at $13,264, with $11,281 of that trading in the last 24 hours alone. How the June 22 NYC Low Temperature Contract Works This contract resolves YES for the 68-69°F band if the verified lowest temperature recorded in New York City on June 22, 2026 falls within that two-degree range. The market resolves at 12:00 PM ET on June 22. Each competing band, from 59°F or below up through 78°F or higher, is its own YES/NO contract. Only one band pays out. YES on 68-69°F is priced at $0.60, implying a 59.5% probability that the overnight low lands in this range.NO on 68-69°F is priced at $0.41, implying a 40.5% probability that the low falls in any other band. For NO to pay out here, the overnight low in NYC must fall outside 68-69°F entirely. That means either a cooler reading of 67°F or below, or a warmer floor of 70°F or higher. A cooler reading would require a stronger-than-expected boundary layer cooling or a late frontal passage. A warmer floor would require sustained southerly flow with above-average dewpoints trapping heat through the night. Either scenario is possible, but the market has priced both as less likely than the current band. Sponsored Partner Momentum and Market Signals Point to Late-Session Conviction The momentum composite here is unambiguous. A 39.0% price surge in 24 hours, flat movement in the last hour, and a trend score of 64.61 together describe a market that found its conviction early this morning and has since stabilized. The most likely driver: observed temperature data from overnight reporting stations confirmed the warm floor that traders had been anticipating. Total volume is $13,264. With $11,281 trading in the last 24 hours, this market got serious very recently. Liquidity sits at $15,742, which is reasonable for a short-duration weather contract. Volume is below the $1 million threshold that signals deep market confidence, so the price remains sensitive to any late observation that contradicts the current read. The 24-hour price change of +39.0% and the flat 1-hour reading together suggest the market reached a consensus quickly and has not faced a meaningful challenge since.The trend score of 64.61 confirms moderate-to-strong directional conviction, not a coin-flip signal.Thin total volume means a single large trade or a surprising temperature reading before noon could reprice this contract sharply.The 68-69°F band’s implied probability of 59.5% leaves meaningful room for adjacent bands, particularly 66-67°F and 70-71°F.The market opened at $0.26 and has more than doubled, which reflects new information arriving overnight rather than a slow drift. Lines Analysis: Warm Air Mass vs. Late Cooling Risk The data right now supports the 68-69°F band. June 22 in New York City sits in the heart of early summer, when overnight lows frequently hold in the upper 60s under humid, stagnant conditions. A warm air mass overhead, combined with the urban heat island effect, makes it structurally difficult for Central Park or JFK stations to dip below 66°F unless a frontal boundary moves through. The market is pricing that physical constraint correctly. The real risk for the NO side is a surface observation that comes in cooler than expected, landing in the 66-67°F band, or warmer, pushing into 70-71°F. A late-arriving sea breeze from the south shore could push the floor higher. Meanwhile, a faster-than-forecast atmospheric clearing could allow more radiative cooling than the model suite predicted overnight. Neither is the base case, but the market’s 40.5% NO price reflects genuine meteorological uncertainty that close to a resolution. National Weather Service observations from Central Park and JFK through early June 22 will be the primary resolution inputs. Any reading below 68°F or above 69°F reprices everything.A late-night or early-morning thunderstorm can temporarily cool surface temperatures, shifting the low into the 66-67°F band.Urban heat island persistence is a YES-supporting factor. NYC rarely sees lows drop sharply on humid June nights without significant synoptic forcing.The 70-71°F band at a lower implied probability represents the warm-floor risk. Sustained southerly advection overnight would shift probability toward that band.Resolution at noon ET means any temperature data recorded before midnight through roughly 6:00 AM would capture the true overnight minimum. Total volume of $13,264 is modest. The data currently favors the 68-69°F YES side, consistent with observed warm overnight conditions. Adjacent bands remain live given thin liquidity. LINES VERDICT WARM NIGHT, NARROW WINDOW The observed temperature pattern heading into June 22 supports the 68-69°F band, and the market’s 24-hour price surge reflects traders reading the same overnight data. Here is what the measurements are telling us: the air mass is warm, the urban floor is elevated, and the math favors this band over any other single outcome. What the market says: At 59.5% implied probability, the market has priced 68-69°F as the most likely outcome but not a certainty. With resolution at noon on June 22 and thin overall volume, any surprising early-morning temperature reading before the cutoff could move this price sharply in either direction. Key unknown: The single most important input is the verified overnight low from official NYC observation stations. If that reading arrives before resolution and falls outside the 68-69°F range, the current price collapses immediately. Frequently Asked QuestionsWhat does 59.5% probability mean for the 68-69°F outcome?It means the market assigns roughly a 3-in-5 chance the NYC overnight low lands in that two-degree band. The other 40.5% is spread across all other temperature ranges, from 59°F or below up to 78°F or higher.What happens to the NO contract if the temperature misses?NO on 68-69°F pays out if the verified NYC low falls anywhere outside that band, whether cooler at 67°F or below, or warmer at 70°F or above. Any adjacent band resolving YES means this NO pays.What data or event would move this market before resolution?An official overnight low observation from Central Park or JFK falling outside 68-69°F would reprice this contract immediately. A late-night storm or unexpected sea breeze are the likeliest physical triggers.When does this market resolve?Resolution is set for June 22, 2026 at 12:00 PM ET. The verified lowest temperature recorded in NYC on June 22 determines which band pays out.Is total volume of $13,264 enough to trust this price?Volume below $1 million signals thin liquidity.

Warm Floor Holds If the urban heat island and humid southerly flow keep NYC's overnight low anchored in the upper 60s, the 68-69°F band resolves YES cleanly. Sustained moisture and stagnant air aloft would prevent meaningful radiative cooling. The market's 59.5% pricing reflects this as the base case, and morning station data confirming 68-69°F would push the price toward 85% or higher before noon. Cooler Dip Undercuts the Band A faster-than-forecast atmospheric clearing or a subtle frontal boundary passage could push NYC's low down to 66-67°F. That outcome collapses the YES price to near zero and pays out the 66-67°F band instead. With thin volume, any official observation below 68°F before resolution would reprice this market in seconds. Adjacent Bands Gain Ground The 70-71°F band represents the warm-floor alternative. If southerly advection intensifies overnight and dewpoints remain elevated, NYC's low could hold above 70°F, transferring probability away from 68-69°F. This band currently prices at a lower implied probability but becomes relevant if morning station readings trend warmer than forecast through the pre-dawn hours. Late Thunderstorm Resets the Low A convective cell moving through the metro area in the early morning hours could temporarily drop surface temperatures several degrees, pushing the overnight low below 67°F. Thunderstorm-driven cooling is notoriously difficult to forecast precisely. If a cell clips Central Park between 2:00 and 5:00 AM ET, the officially recorded low could shift to the 64-65°F or 66-67°F band, resetting this market entirely. Key macro factor: Late June in New York City sits within a climatological period of elevated overnight lows driven by urban heat retention and increasing Atlantic moisture, which systematically skews overnight minimums toward the upper-60s range compared to historical averages from earlier decades.
