June 22 falls one day after the summer solstice, and the market is now pricing a 40.5% chance that the city’s daily high stays at or below 24°C. That is a notably cool outcome for one of China’s so-called furnace cities. The momentum signal tells the sharper story: price has dropped roughly 10% over the past 24 hours, driven by forecasts pointing toward warmer conditions than the ≤24°C threshold requires. The market question asks: what is the highest temperature in Chongqing on June 22? The outcome priced here, “24°C or below,” carries a YES price of $0.41. The NO side, covering all warmer outcomes from 25°C up to 34°C or higher, sits at $0.60. This market resolves on June 22, 2026 at 12:00 UTC. Total volume stands at $16,661, with $12,796 of that trading in the past 24 hours. How This Chongqing Temperature Contract Works YES pays out if official temperature records confirm Chongqing’s June 22 daily maximum at 24°C or below. NO covers every warmer outcome. The contract is a multi-outcome structure, so the competing buckets from 25°C through 34°C-or-higher each carry their own prices. For the ≤24°C outcome specifically, traders are betting the city stays unusually cool on the day after the summer solstice. YES (24°C or below): $0.41 per share, implying 40.5% probability.NO (25°C or higher): $0.60 per share, implying 59.5% probability across all warmer buckets. A reading above 24°C is enough to defeat this contract. Chongqing typically posts June highs well into the upper 20s and low 30s. For NO to pay out, temperatures simply have to behave like a normal early-summer day in a basin city known for intense heat. The barrier is not a record warmth event. It is just ordinary June weather. Sponsored Partner Momentum and Market Signals The momentum composite is bearish for the ≤24°C outcome. The 1-hour change of -7.5%, combined with a -10.0% move over 24 hours and a trend score of 62.03, points to a single driver: incoming weather forecasts for June 22 are tracking warmer than the 24°C ceiling. When short-range forecast models update and point toward 27-31°C highs, the ≤24°C bucket loses value quickly. Total volume at $16,661 is modest, and 24-hour volume of $12,796 shows most activity concentrated in the final trading window. Liquidity is $53,293, which is healthy relative to volume. Because total volume is below $1 million, a single large position can move this price meaningfully. The order book is not deep enough to absorb a strong forecast revision without repricing sharply. The 1-hour and 24-hour price drops both accelerate on the same driver: warming forecast signals for the June 22 window.Trend score of 62.03 sits above neutral, suggesting the bearish move has momentum but has not gone parabolic.Liquidity at $53,293 is sufficient for small-to-medium trades, but the thin total volume means volatility risk is elevated into resolution.Trader sentiment breakdown sits at 40.5% YES and 59.5% NO, consistent with the current price.No whale trades are recorded in this market, so price movement reflects distributed retail positioning rather than a single large bet. Lines Analysis: Chongqing’s Climate Profile vs. the 24°C Threshold Chongqing’s basin geography is the central fact here. The city is surrounded by mountains that restrict airflow and trap solar radiation. June average daily highs in Chongqing historically run from 28°C to 33°C. For the daily maximum to stay at or below 24°C on June 22, the city would need sustained cloud cover, active rainfall, or an unusually strong cold air intrusion. Early-season monsoon pulses can briefly suppress temperatures, but a full-day cap below 25°C this late in June is rare. The realistic path to a sub-25°C high requires a persistent rain event covering the entire daylight window. Without that sustained precipitation, afternoon temperatures in the basin almost always breach 24°C by early afternoon. The meteorological bar is not impossible but it is specific: cloud cover alone rarely holds Chongqing below 24°C in late June without active rainfall. Short-range weather model updates for June 22 are the single most important signal to watch.Any forecast shift toward sustained rainfall and thick cloud cover would push YES probability higher.Forecast clearing toward partly cloudy or sunny conditions would push YES probability toward the low 20s or below.China Meteorological Administration advisories for Chongqing municipality will be the resolution reference.Related market “Where will 2026 rank among the hottest years on record?” pricing at 70% reflects the broader warm-year context that makes a sub-24°C day in late June even less probable. Total volume of $16,661 is thin. The data favors the NO side based on Chongqing’s climate profile and the downward price momentum of the past 24 hours. The ≤24°C outcome needs specific meteorological conditions that current forecasts do not appear to support. LINES VERDICT LEAN NO, WARMER OUTCOME FAVORED Chongqing’s basin climate and the summer solstice timing both work against a daily high at or below 24°C. The market’s sharp downward move over the past 24 hours reflects exactly that: forecast data is not cooperating with the cool scenario. What the market says: At 40.5% implied probability, the market has already shifted toward warmer outcomes. Thin total volume means the final forecast update before resolution could move this price by 10 to 15 percentage points in either direction. Key unknown: The single most important variable is the June 21 to June 22 overnight and morning weather pattern for Chongqing. A confirmed persistent rain event with thick cloud cover would be the only realistic path to keeping the daily maximum at or below 24°C. Scientific Context: Chongqing as a Furnace City Chongqing earned its informal designation as one of China’s three furnace cities because the Jialing and Yangtze rivers converge there inside a mountain basin. The basin traps heat and humidity during summer months. June is the transition month into peak heat, with average daily highs already approaching 30°C by the third week of the month. The summer solstice on June 21 marks near-maximum solar radiation at this latitude. A high of 24°C or below on June 22 would rank as a significant outlier for this location and date. The broader 2026 context, with the year tracking as one of the hottest on record globally, adds further pressure against the cool outcome. Frequently Asked QuestionsWhat does 40.5% probability mean for this market?It means traders currently price a 40.5% chance Chongqing's June 22 daily high stays at or below 24°C. Roughly six in ten bettors expect a warmer outcome.What happens to this contract if the temperature is 25°C?A high of 25°C defeats the 24°C-or-below outcome. The NO side, and specifically the 25°C bucket, would pay out. Any reading above 24°C resolves YES as losing.What data would move this price before resolution?Short-range weather forecast updates from China Meteorological Administration for Chongqing on June 22. A forecast shift toward sustained rainfall and cloud cover would push YES probability higher.When does this market resolve?The market resolves on June 22, 2026 at 12:00 UTC, based on the official recorded daily maximum temperature for Chongqing.Is this market reliable given the low trading volume?Total volume is $16,661, which is thin.

Persistent Rain Keeps Chongqing Cool A slow-moving rain system stalls over Chongqing on June 22, delivering thick cloud cover and steady rainfall throughout the day. Afternoon temperatures fail to breach 24°C. Short-range forecast models update to show this scenario, and YES price climbs back toward 60% as traders reprice the cool outcome as plausible. Clear Skies Push Temperatures Into the Upper 20s Forecast models confirm partly cloudy to sunny conditions for Chongqing on June 22. The basin traps solar radiation and afternoon temperatures reach 28-31°C. YES price collapses toward 10-15% as traders exit the cool-outcome position entirely before resolution. Late Monsoon Pulse Surprises Markets An unexpected cold air intrusion from northern China pushes into the Sichuan Basin overnight on June 21. Morning temperatures stay suppressed and cloud cover holds through the afternoon. The daily high barely clears 23°C and the 24°C-or-below outcome resolves YES, rewarding traders who held through the bearish momentum. Measurement Dispute at Resolution An unusual situation where official temperature station readings for Chongqing on June 22 differ between sources creates resolution ambiguity. If the China Meteorological Administration and alternative data sources report different highs straddling the 24°C threshold, resolution could be delayed or contested, creating short-term price volatility. Key macro factor: 2026 is tracking as one of the hottest years on record globally, which increases the baseline probability of above-average temperatures in Chongqing and reduces the likelihood of a sub-25°C daily maximum near the summer solstice.
