The contract resolves at noon ET on July 11, 2026, and traders have just hours to be right about a two-degree temperature band. The 82-83°F outcome holds a 35.5% implied probability, making it the single most likely outcome in a crowded field but far from a consensus call. The market question asks: what will the highest temperature in NYC be on July 11? The 82-83°F band sits at $0.36 YES and $0.65 NO. Total volume stands at $56,288, with $51,296 of that arriving in the last 24 hours. The contract closes at 12:00 PM ET today. How the Eighty-Two to Eighty-Three Degree Contract Works This contract resolves YES if the official high temperature recorded in New York City on July 11, 2026, falls between 82°F and 83°F inclusive. Any reading outside that band, whether cooler or warmer, resolves NO. Resolution follows the market’s stated source for official temperature measurement. Ten alternative outcome contracts cover the full range from 69°F or below up through 88°F or higher. YES ($0.36, 35.5% probability): NYC hits a high of exactly 82°F or 83°F on July 11.NO ($0.65, 64.5% probability): NYC’s high falls outside that two-degree window, in any direction. The NO side covers nine other outcome bands. The temperature only needs to climb to 84°F, or stall at 81°F, for NO to pay. A single degree separates this outcome from its nearest neighbors, and urban heat dynamics in July mean afternoon convection or a sea breeze can shift readings by two to three degrees within hours. Sponsored Partner Momentum and Market Signals Heading Into Resolution The momentum composite here is bearish for the 82-83°F outcome. The 24-hour price change of -5.0% combined with a trend score of 46.76 (below neutral 50) signals traders have been rotating probability mass toward adjacent bands, most likely the 84-85°F or 80-81°F outcomes, as forecast models updated overnight. Volume tells the real story on conviction. Total volume is $56,288, with $51,296 arriving in the last 24 hours alone. That means roughly 91% of all trading in this market happened today. Liquidity stands at $102,741, which is healthy relative to volume and means a single large trade won’t crater the price. Still, at under $1M total volume, this market can reprice sharply on any late-breaking forecast update or early afternoon temperature reading. The 24h price decline of -5.0% reflects forecast model updates that have likely shifted expected highs slightly outside the 82-83°F window.The 1h change of 0.0% shows the market has stabilized, suggesting traders are holding positions ahead of resolution rather than continuing to rotate.The trend score of 46.76 sits just below neutral, confirming mild bearish lean without a strong directional signal.Volume concentration in the last 24 hours indicates informed short-term traders dominate this contract, not long-term holders.Liquidity of $102,741 against $56,288 volume suggests market makers are well-capitalized relative to trading activity. Lines Analysis: What Drives the NYC Temperature Outcome July 11 falls in the heart of New York City’s warmest period. The National Weather Service climatological average high for mid-July in NYC runs between 83°F and 85°F at Central Park. That baseline puts the 82-83°F range squarely in plausible territory, which explains why it holds the plurality at 35.5%. A modest high-pressure system or lingering cloud cover from overnight convection would keep readings in this band. What makes the NO side real is the same July volatility that makes this contract interesting. Sea breeze intrusion off the Atlantic can hold coastal readings three to five degrees below inland stations. An afternoon thunderstorm can break the heat before the official daily high is recorded. Alternatively, a persistent southwest flow can push readings above 85°F before noon. The 64.5% NO probability reflects how many ways a two-degree band can miss in either direction. The National Weather Service afternoon forecast update, if released before 12:00 PM ET, would be the single most direct repricer for this contract.A confirmed high above 84°F on NWS data would collapse YES probability toward zero within minutes of resolution.A stalled morning high in the 80-81°F range, common when overnight cloud cover persists into the morning, would similarly resolve NO.Any official reading of exactly 82°F or 83°F at the primary NYC station locks in YES at resolution.Late-breaking surface observation data from ASOS stations at Central Park or JFK would be the definitive signal for holders. Total volume of $56,288 is thin by prediction market standards. The data right now favors the NO side at 64.5%, reflecting the genuine difficulty of hitting a precise two-degree band in a city where July temperature variability is high. The 82-83°F outcome is the most likely single band, but most of the probability mass sits elsewhere. LINES VERDICT Narrow Miss More Likely Than Not The 82-83°F band is the most probable single outcome, but a 35.5% implied probability means the market has already concluded it is more likely to miss than hit. July heat dynamics in NYC make two-degree precision genuinely difficult. What the market says: At 35.5% implied probability, the market prices this as a real but minority outcome. With resolution arriving at noon ET today, any volatility in the final hours will be driven entirely by observed temperature data, not forecast shifts. Key unknown: The official high temperature reading from the primary NYC observation station before 12:00 PM ET is the only fact that matters now. Any confirmed reading outside 82-83°F immediately resolves this contract NO. Scientific Context: NYC July Temperature Patterns New York City’s July temperature record shows high variability driven by urban heat island effects, Atlantic sea breeze penetration, and synoptic weather patterns. The climatological average high in early-to-mid July at Central Park runs near 83-84°F, placing the 82-83°F target band just below the long-run mean. Years with strong Bermuda High influence push highs consistently above 86°F. Years with active Atlantic storm tracks keep highs in the 78-82°F range. The market’s spread across ten outcome bands accurately reflects this real-world variability. No single two-degree band captures more than roughly 35-40% of historical July days, which is consistent with the current market pricing. Frequently Asked QuestionsWhat does 35.5% probability mean for the 82-83°F outcome?It means the market prices roughly one-in-three odds that NYC's official high on July 11 lands in exactly that two-degree band. The other 64.5% of probability is spread across nine alternative temperature ranges.What does the NO contract pay out on?NO pays if NYC's official high temperature on July 11 falls anywhere outside 82-83°F. That includes readings of 81°F or below, or 84°F or above. Nine other outcome bands cover the full temperature range.What data would move this market before resolution?Any updated National Weather Service observation or ASOS station reading showing the NYC high already recorded outside 82-83°F would immediately collapse YES probability. This contract resolves at 12:00 PM ET today.When does this market resolve?The contract resolves at 12:00 PM ET on July 11, 2026, based on the official highest temperature recorded in New York City during that period.Is the volume reliable enough to trust the price?Total volume is $56,288, well under $1M. Prices can shift sharply on a single trade or new temperature data. Liquidity of $102,741 provides some stability, but this is a thin market by prediction market standards.How is the Smart Money Index calculated?We aggregate the live positions of the top 50 Polymarket whales (ranked by 30-day tracked volume) into one composite reading per market.

Morning High Locks In A dry morning with light winds and a persistent high-pressure ridge pushes NYC temperatures to exactly 82-83°F before a sea breeze arrives. The official station records the high before noon, and the two-degree band captures the day's peak. YES probability surges to near certainty in the final minutes before resolution. Heat Pushes Past Eighty-Four A strengthening southwest flow advects warm air from the mid-Atlantic into NYC overnight and through the morning. Surface temperatures climb past 84°F at Central Park before 11:00 AM ET. The 84-85°F or 86-87°F outcome contracts surge while the 82-83°F band resolves NO. Sea Breeze Caps the High An Atlantic sea breeze penetrates Manhattan by mid-morning, holding coastal station temperatures at 82-83°F even as inland areas push warmer. If the primary resolution station sits in a cooled corridor, the two-degree band captures the official high and YES resolves at full value. Morning Thunderstorm Breaks the Heat Early An overnight mesoscale convective system leaves residual clouds and cooled surface air across NYC into the morning. Temperatures stall in the 78-81°F range, never reaching 82°F before noon. The low-end outcome bands (80-81°F or 78-79°F) capture the resolution, and the primary outcome resolves NO from the cool side. Key macro factor: No significant El Nino or La Nina signal is currently driving NYC July temperature anomalies above or below the climatological baseline for this specific date.
