The 32°C outcome has surged to 44% implied probability, up more than 21 percentage points in the last hour alone. That kind of momentum on a 24-hour weather contract means traders are repositioning hard on fresh forecast data. Here’s what the measurements are telling us: the market is not settled, and the gap between 32°C and its nearest rivals is still very much in play. The market question asks: what is the highest temperature in Guangzhou on June 26? The 32°C outcome is priced at $0.44 YES and $0.56 NO. The contract resolves on June 26 at 12:00 UTC. Total volume stands at $68,404, with $51,079 traded in the last 24 hours alone. How the Guangzhou Temperature Contract Works This contract resolves to YES on the 32°C outcome if the verified daily maximum temperature in Guangzhou on June 26 equals exactly 32°C. Resolution draws from official meteorological observation data. Every other temperature band, 27°C or below up through 37°C or higher, is a separate tradeable outcome. Buying YES on 32°C means you believe the thermometer peaks at that specific degree, not 31°C, not 33°C. 32°C YES is priced at $0.44, implying a 44% probability of resolution at that exact threshold.32°C NO is priced at $0.56, implying a 56% probability the daily high lands on any other outcome. The NO side wins if Guangzhou’s measured daily maximum lands anywhere outside 32°C. That means a cooler-than-expected day pushing the high to 31°C or below, or a hotter surge driving it to 33°C or above, both resolve this contract NO. Late June in Guangzhou sits in the heart of its humid subtropical summer, where daily highs in the low-to-mid 30s are the norm, but single-degree precision makes any one outcome genuinely uncertain. Momentum and Market Signals Sponsored Partner Sharp Moves and Thin Volume The momentum composite here is unusually strong. A trend score of 83.85, combined with a 21.5% one-hour price jump and a 17.5% 24-hour gain, points to a catalyst. The most likely driver is updated short-range forecast data for Guangzhou on June 26, probably from a regional or global numerical weather prediction model refresh. When a one-day weather market moves this sharply this close to resolution, fresh forecast numbers are almost always the explanation. Total volume of $68,404 is modest. The $41,176 in liquidity means price can shift significantly on any meaningful new bet. At this volume level, a single large trade could reprice the 32°C outcome by several percentage points. Treat the current 44% probability as directionally meaningful but not deeply anchored. The 32°C outcome has gained 21.5% in the last hour, the clearest momentum signal in this market right now.24-hour volume of $51,079 represents the vast majority of total traded volume, meaning most conviction entered today.Liquidity at $41,176 is thin enough that new forecast data or a large trade could move this price sharply before resolution.The trend score of 83.85 ranks this among the more directional short-term momentum readings for a single-day climate market.Trader sentiment sits at 44% YES and 56% NO, a mild bearish lean that the recent price surge has not yet fully overturned. Lines Analysis: Guangzhou on June Twenty-Six The case for 32°C rests on climatology and the current forecast signal. Late June daily highs in Guangzhou cluster tightly in the 31°C to 35°C range. A peak at exactly 32°C is plausible given typical synoptic patterns, and the sharp intraday price surge suggests at least one updated numerical forecast is pointing the thermometer toward that band. The data doesn’t care about the politics, and right now the data appears to be nudging traders toward the lower end of the mid-30s range. What makes NO compelling is the precision problem. Even if 32°C is the most likely single outcome, the probability of hitting exactly that degree, rather than 31°C or 33°C, is structurally limited. A slight afternoon surge from sea breeze collapse, a persistent cloud deck, or a passing convective shower could shift the measured daily maximum by one full degree in either direction. The competing outcomes at 31°C and 33°C are both live, and their combined probability mass is significant. Any updated June 26 Guangzhou forecast from a major NWP model (ECMWF, GFS, CMA) pointing above 33°C would shift volume toward the 33°C or 34°C outcomes and pressure the 32°C price downward.A forecast revision toward 31°C or below, perhaps tied to increased cloud cover or tropical moisture intrusion, would also push the 32°C outcome lower.Observed morning temperatures in Guangzhou on June 26 will be the strongest leading indicator for afternoon peak, and traders should watch early station reports closely.Thin liquidity means resolution-day price discovery could be rapid and sharp once early observational data becomes available. The market is pricing uncertainty, not science. With $68,404 in total volume, this is a lightly traded single-day contract where forecast revisions and real-time observations drive price more than deep liquidity. The 44% probability on 32°C is a reasonable reflection of climatological base rates for this exact temperature band, slightly boosted by whatever forecast signal drove today’s surge. LINES VERDICT OUTCOME UNCERTAIN, MOMENTUM FAVORS THIRTY-TWO The sharp intraday surge points to a credible forecast signal for 32°C, but single-degree precision on a summer day in Guangzhou makes this genuinely a coin-flip-plus scenario. The data favors watching, not declaring. What the market says: At 44% implied probability, the market has moved decisively toward 32°C over the last 24 hours, but the majority of probability mass still sits on other outcomes. Thin liquidity means this price could shift dramatically in the final hours before the June 26 resolution. Key unknown: The single most important input is the verified peak temperature reading from Guangzhou meteorological stations on June 26. Any late-morning forecast update pointing clearly above 33°C or below 31°C would reprice this contract immediately. Frequently Asked QuestionsWhat does 44% probability mean for the 32°C outcome?It means traders currently estimate a 44% chance that Guangzhou's official daily maximum on June 26 lands exactly at 32°C. More than half the market expects a different temperature band to win.How does the NO contract resolve on this market?NO on 32°C resolves YES if the Guangzhou daily high on June 26 lands at any temperature other than 32°C, whether that is 31°C, 33°C, or any other listed outcome band.What data or event would move this market's price most?Updated short-range weather model forecasts for Guangzhou on June 26, particularly from ECMWF or CMA, and real-time morning temperature station readings on resolution day are the primary price drivers.When does this market resolve?The market resolves on June 26, 2026 at 12:00 UTC, based on verified official meteorological data for Guangzhou's daily maximum temperature.Is this market liquid enough to trust the price signal?Total volume is $68,404 with $41,176 in liquidity. That is thin. A single large trade can shift the price by several percentage points, so treat the 44% probability as directional, not deeply anchored.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.

Market Resolved Outcome: YES Final Price 100% Settled Jun 26, 2026 Duration 2 days Resolution Analysis Forecast Locks In Thirty-Two Multiple updated NWP model runs converge on a Guangzhou peak in the 32°C range for June 26, driven by moderate cloud cover limiting afternoon heating. Traders pile into the 32°C outcome on resolution day. Thin liquidity amplifies the move and the probability climbs well above 50% before the final reading is confirmed. Heat Surge Pushes Past Thirty-Three A late-June ridge of high pressure clears cloud cover over the Pearl River Delta on June 26. Afternoon temperatures accelerate past 32°C and peak at 33°C or 34°C. The 32°C outcome collapses as volume shifts to higher-band contracts, and NO holders on 32°C collect. Cloud Cover Caps the Day at Thirty-One Tropical moisture or a mesoscale convective system moves through the Guangzhou area on June 26, keeping the afternoon high at 31°C. The 32°C outcome resolves NO. The 31°C contract, currently a lower-priced alternative, surges to the winning position as real-time station data confirms the cooler peak. Instrument or Data Reporting Anomaly Official meteorological station data for Guangzhou reports a reading that conflicts with forecast consensus, perhaps due to urban heat island variation between stations or a late data revision. The resolution source faces ambiguity. Market price oscillates sharply in the final minutes as traders interpret which reading governs official resolution. Key macro factor: Late June places Guangzhou in its peak summer monsoon transition window, where synoptic-scale patterns from the western Pacific subtropical high directly govern daily temperature maxima and introduce day-to-day variability of plus or minus two to three degrees Celsius.
