The question is narrow: does the city’s highest temperature on May 15 land exactly at 25 degrees Celsius? Not 24, not 26. Twenty-five. That precision is what makes this contract interesting, and it’s why the market has settled into a clear lean against that outcome. The contract resolves at 2026-05-15 12:00:00. The current implied probability sits at 22% for YES (a peak of exactly 25°C) and 78% for NO (any other temperature). Total trading volume is $1,652, with $1,608 of that arriving in the last 24 hours. Liquidity stands at $39,683. At this volume level, a single significant trade can shift the price sharply before resolution. How the Contract Works: The 25°C Threshold in Chongqing YES pays out if Chongqing’s official highest temperature on May 15 is recorded at exactly 25°C. NO pays out if the daily maximum lands at any other value across the listed outcomes: 17°C or below, 18°C, 19°C, 20°C, 21°C, 22°C, 23°C, 24°C, 26°C, 27°C or higher. The resolution source is market resolution, meaning the outcome depends on officially reported temperature data for Chongqing on that date. YES (25°C peak): priced at 0.22, implying a 22% probability.NO (any other temperature): priced at 0.78, implying a 78% probability. The NO side doesn’t require any single specific outcome. It wins if Chongqing hits 24°C, 26°C, or anything else on the listed slate. The probability weight spread across 10 alternative outcomes is what makes 25°C individually hard to price above 22%. Chongqing’s climate in mid-May is transitional: the city moves from mild spring conditions toward its famously hot and humid summer. Historical mid-May highs in the municipality cluster between 22°C and 30°C, with meaningful variance year to year. Landing precisely on 25°C, rather than one degree warmer or cooler, requires a narrow alignment of atmospheric conditions. Sponsored Partner Momentum and Market Signals: Flat Trend, Heavy Last-Day Volume The momentum composite here tells a specific story. The 1-hour price change is flat at +0.0%, the 24-hour change is not available, and the trend score sits at 33.56. That combination points to a market that has settled into a position and is waiting for the forecast to either confirm or surprise. No significant data event has moved this contract in recent hours. The volume split is worth flagging directly. Total market volume is $1,652, and $1,608 of that arrived in the last 24 hours. That means nearly all trading activity is very recent, concentrated right before resolution. Liquidity at $39,683 is deep relative to total volume, but with trading this thin, a single trader adding meaningful size could move the YES price off 0.22 before May 15 arrives. This is a low-volume market, and price reliability reflects that. The 1-hour price change of +0.0% and trend score of 33.56 together signal no active repricing pressure as of 2026-05-13 09:17:01.Total volume of $1,652 classifies this as a low-liquidity market. Price can move sharply on any new forecast signal or large trade.The YES price of 0.22 has held a narrow range between 0.20 and 0.22 across the available price history. No dramatic repricing has occurred.The 24-hour volume of $1,608 represents a late surge of interest, likely driven by traders positioning as May 15 approaches.Open interest is reported at $0, which combined with thin volume suggests most activity reflects short-duration positioning rather than long-held conviction. Lines Analysis: What the Chongqing Forecast Implies The strongest signal supporting NO is simple probability distribution. Eleven temperature outcomes are listed in this market. Even if each were equally weighted, YES would hold roughly 9% probability. The 22% YES price implies traders believe 25°C is more likely than a random draw, but still well below even odds. That pricing is consistent with mid-May in Chongqing being genuinely hospitable to temperatures in the mid-20s range, while acknowledging the coin-flip nature of landing on one specific degree. What makes the NO position straightforward is that 26°C or 27°C or higher outcomes are realistic alternatives for a Chongqing May day. The municipality sits in a basin that traps heat efficiently. A warmer-than-typical air mass arriving ahead of May 15 could push the daily maximum above 25°C without much effort. Equally, a cloudy or rainy day could hold the high at 23°C or 24°C. The 25°C bull case requires the atmosphere to thread a narrow needle. Chongqing Meteorological Bureau forecasts for May 14 to 16 are the single most important input before resolution. Any forecast showing highs above 26°C or below 24°C would push YES toward 0.10 or lower.Regional weather pattern shifts, including any approaching frontal systems from the southwest or northeast, could change the projected high by two to three degrees in 48 hours.The YES price of 0.22 has not moved off its range despite the volume surge, suggesting traders who entered recently agreed with prior positioning rather than challenging it.If Chongqing’s regional forecast tightens to a range of 24°C to 26°C for May 15, YES could see modest repricing upward as the specific-degree probability increases. At $1,652 total volume, this market reflects a niche positioning exercise rather than broad forecast consensus. The data favors NO clearly, not because 25°C is impossible, but because 10 alternative outcomes collectively absorb the remaining 78% probability. Here’s what the measurements are telling us: mid-May Chongqing temperature variance is wide enough that pinning one degree is a low-probability outcome by definition. LINES VERDICT NO Favored, Thin Market The probability distribution across eleven outcomes makes any single temperature difficult to back above 22%, and Chongqing’s mid-May climate variance reinforces NO as the structurally dominant position here. What the market says: At 22%, traders see 25°C as a plausible but unlikely outcome for May 15. With resolution arriving in roughly 48 hours and volume concentrated in the last day, any shift in the Chongqing short-range forecast before 2026-05-15 12:00:00 could move this price quickly given thin overall liquidity. Key unknown: The Chongqing Meteorological Bureau’s May 14 to 15 short-range forecast is the single variable that matters most. A forecast pinpointing highs between 24°C and 26°C would justify YES moving toward 0.30 or above. A forecast outside that window collapses it. Scientific Context: Chongqing’s Climate in Mid-May Chongqing sits in the Sichuan Basin at low elevation, surrounded by mountains that limit air circulation and trap heat. May marks the transition from spring to pre-summer conditions. Average daily highs in mid-May typically range from the low 20s to the high 20s Celsius, depending on synoptic weather patterns. The city is known for high humidity and frequent cloud cover, which moderates extreme highs in spring but also suppresses cold air intrusions. A 25°C reading on May 15 is climatologically plausible, sitting near the center of historical mid-May temperature distributions. What makes it unlikely in a prediction market context is the requirement for exact precision rather than a range. The market is pricing uncertainty, not science. The climate record says mid-May can deliver 25°C. It can also deliver 23°C or 28°C with roughly comparable frequency depending on the synoptic setup. Before 2026-05-15 12:00:00, the one event that would reprice this contract meaningfully is a consensus short-range forecast placing Chongqing’s May 15 high within a one-degree band centered on 25°C. Frequently Asked Questions What does 22% probability mean here? It means traders collectively estimate a roughly one-in-five chance that Chongqing’s official peak temperature on May 15 lands exactly at 25°C, not any other listed value.What does the NO contract cover? NO wins if Chongqing’s May 15 high is anything other than 25°C, including 24°C, 26°C, 27°C or higher, or any lower value listed in the contract outcomes.What data event would move this price before resolution? A Chongqing Meteorological Bureau short-range forecast for May 15 showing a projected high within one degree of 25°C would push YES higher. A forecast far outside that range would push YES toward its floor near 0.10.When does this market resolve? Resolution is set for 2026-05-15 12:00:00, based on officially reported temperature data for Chongqing on that date.Is the $39,683 liquidity figure reliable? Liquidity is deep relative to total volume of $1,652, but with this little trading activity, the YES price can shift significantly on a single large trade. Treat the current price as directionally informative, not precisely calibrated. This analysis reflects market conditions as of 2026-05-13 09:17:01. Prediction market probabilities are volatile and shift as new data and regulatory decisions emerge, especially as the 2026-05-15 12:00:00 resolution date approaches.

Market Resolved Outcome: YES Final Price 100% Settled May 15, 2026 Duration 2 days Resolution Analysis Forecast Narrows to 25C Band If the Chongqing Meteorological Bureau's 48-hour forecast for May 15 centers on a high of 24C to 26C, traders may reprice YES above 0.30. A stable high-pressure system keeping temperatures moderate and consistent would increase the probability that the daily maximum lands on exactly 25C rather than overshooting into the upper 20s. Warm Air Mass Pushes High Above 26C Chongqing's basin geography is efficient at trapping heat. If a warmer-than-normal air mass moves into the Sichuan Basin ahead of May 15, the daily maximum could easily reach 27C or higher. That scenario collapses the YES price toward its floor near 0.10, as the 25C outcome becomes a clear miss. Cloud Cover Holds High Near 25C Chongqing experiences frequent spring cloud cover that moderates daily highs. A partly cloudy May 15 with no strong warm advection could hold the peak right in the 24C to 25C range. If forecasts tighten to that band in the final 24 hours, YES trades upward as a precise landing at 25C becomes a credible scenario. Late Frontal System Disrupts Forecast A frontal passage arriving earlier or later than forecast could shift Chongqing's May 15 high by three to four degrees in either direction within hours. If a front arrives mid-afternoon rather than overnight, the daily maximum could drop from a projected 26C to 23C or below, making the precise 25C outcome irrelevant and pushing volume into lower-temperature alternatives. Key macro factor: Chongqing's mid-May climate sits in a transitional zone between spring moderation and pre-summer heat buildup, with El Nino or La Nina phase influencing whether regional temperatures trend above or below climatological norms for the period.
