The city earns its reputation as one of China’s “furnace cities” through brutal summer heat that regularly pushes daily highs well above 30°C. Yet the prediction market for July 3 tells a more complicated story: the single-outcome contract for 28°C sits at just 29.5% implied probability, while traders have spread their bets across a wide temperature range from 24°C or below all the way to 34°C or higher. The market is pricing uncertainty, not science. This contract asks one specific question: will Chongqing’s highest temperature on July 3 land exactly at 28°C? The YES price sits at 0.30, the NO price at 0.71, and the market resolves at 2026-07-03 12:00 UTC+8. Total volume is $4,942, with all of that activity recorded in the last 24 hours. This is a brand-new, thin market where a single large trade can move the price meaningfully. How the Contract Works: Chongqing High Temperature on July 3 This contract resolves YES if Chongqing’s official highest temperature on July 3, 2026, is recorded at exactly 28°C. Any other reading, whether 27°C, 29°C, 30°C, or anything else across the full range of listed outcomes, resolves this specific contract NO. The resolution source is the market itself, which will rely on official meteorological data for Chongqing. The contract closes at 12:00 UTC on July 3. YES (28°C exactly): priced at 0.30, implying a 29.5% probability.NO (any other temperature): priced at 0.71, implying a 70.5% probability. The NO side pays out if Chongqing’s daily high lands anywhere other than 28°C. Chongqing’s July climatology skews warm: historical averages for early July put daily highs in the 32°C to 36°C range. A reading as low as 28°C would require a significant cooling event, cloud cover, or precipitation to suppress afternoon temperatures. The barrier for NO is simply the breadth of the temperature distribution: with outcomes spread across ten discrete bins, any single bin carries a structural ceiling on its probability. Sponsored Partner Momentum and Market Signals: A Thin Book With Fresh Activity The momentum composite here is flat but directionally neutral. The 1-hour price change is zero, the trend score sits at 41.31 (below the midpoint of a 0-100 scale), and the 24-hour change is unavailable because this market opened within the last 24 hours. The driver is straightforward: this contract launched today, July 1, and all trading activity reflects initial positioning ahead of a 48-hour resolution window. Total volume is $4,942, with all $4,942 recorded in the last 24 hours. Liquidity sits at $39,470, which is the most meaningful number here: the order book is roughly eight times deeper than the volume traded so far. That means the price of 0.30 is reasonably stable at current levels, but the volume itself is well below the $1 million threshold. Any coordinated repositioning from a single trader, or a sharp shift in the weather forecast for Chongqing on July 2, could move this contract several cents in either direction quickly. The 28°C outcome opened at 0.23 on July 1 and has since moved to 0.30, a gain of roughly 30% in absolute price terms since open.The 1-hour momentum is flat at 0.0%, suggesting the initial buying wave has paused as of the July 1 evening snapshot.Trader sentiment reads as strongly bearish for YES: 29.5% YES versus 70.5% NO reflects that most capital has gone to the NO side.The trend score of 41.31 places this contract in slightly bearish territory relative to a neutral reading of 50.Volume below $1 million means this price is not a heavily tested consensus. New weather forecast data or a single large bet could shift it sharply before July 3. Lines Analysis: What the Chongqing Climate Data Actually Says Here’s what the measurements are telling us. Chongqing’s July climatology is well-documented. The city sits in the Sichuan Basin, which traps heat and moisture during summer months. July daily highs in Chongqing typically range from the low 30s to the upper 30s Celsius. A high of exactly 28°C on July 3 would represent a below-average reading for this time of year. That does not make it impossible: frontal systems, heavy rainfall, or unusual cloud cover can suppress afternoon temperatures even in early July. But 28°C sits on the cooler end of the plausible distribution. The structural challenge for NO here is not that 28°C is unlikely. It is that NO captures every outcome that is not 28°C. The temperature could land at 35°C and NO still pays. The temperature could land at 27°C and NO still pays. With ten discrete outcome bins in this market, the probability mass for any single bin is naturally capped. The market has distributed that cap at about 30% for 28°C, which implies traders believe warmer outcomes (29°C, 30°C, 31°C, 32°C, 33°C, 34°C or higher) collectively hold the majority of probability weight. Given July climatology for Chongqing, that distribution makes intuitive sense. China Meteorological Administration forecasts for Chongqing in the July 1-3 window are the single most important input for repricing this contract before resolution.Any forecast showing a frontal boundary or precipitation event over Chongqing on July 3 would push the 28°C and 27°C bins higher and pull the 32°C-plus bins lower.Any forecast confirming clear skies and high pressure over the Sichuan Basin would do the opposite: push probability mass toward the warmer bins.The 30°C and 31°C outcome contracts are the most natural alternatives to watch: if those contracts gain volume, it signals trader consensus is moving toward a hot, dry July 3.Resolution is hard and fast at 12:00 UTC on July 3. There is no ambiguity about the timeline. The data doesn’t care about the politics, and in this case there is no politics. This is a pure meteorological bet on a 48-hour forecast for one of China’s hottest cities. Total volume of $4,942 is thin. The 28°C contract sits at a price that is plausible given the multi-bin structure of the market, but it is not a signal of strong conviction in either direction. The liquidity backstop of $39,470 means the price is stable for now, but the forecast data released on July 2 will do the real repricing work. LINES VERDICT LEANING NO, STRUCTURALLY Chongqing’s July climatology runs warmer than 28°C in most years, and the multi-bin structure of this market means any single temperature outcome carries a probability ceiling. The 28°C contract at 29.5% is priced about right for a below-average outcome in a city known for furnace-level July heat. What the market says: A 29.5% implied probability on the 28°C outcome reflects the mechanical reality of a ten-bin temperature market: no single outcome can dominate. Price volatility is real here given the thin $4,942 in total volume and the 48-hour window before the July 3 resolution. Key unknown: The China Meteorological Administration forecast for July 3 in the Sichuan Basin, specifically whether a frontal system or precipitation event arrives before afternoon peak temperatures. That single data point will reprice every temperature bin in this market. Frequently Asked QuestionsWhat does 29.5% probability mean for the 28°C outcome?It means traders currently assign roughly a one-in-three chance that Chongqing's official high on July 3 lands exactly at 28°C. Nine other temperature bins share the remaining probability.How does the NO contract pay out here?NO pays out if Chongqing's July 3 high is anything other than exactly 28°C. That includes every listed outcome from 24°C or below up to 34°C or higher.What data event would most move this contract's price?The China Meteorological Administration's July 2 forecast for Chongqing. A precipitation or frontal system forecast pushes cooler bins higher. A clear-sky forecast shifts probability toward warmer bins above 30°C.When does this contract resolve?The market resolves at 12:00 UTC on July 3, 2026, based on Chongqing's official recorded daily high temperature for that date.Is the $4,942 in volume enough to trust this price?No. Volume below $1 million means the 0.30 price reflects limited trader activity. Liquidity sits at $39,470, so the book is stable, but one large bet or a new forecast could shift the price sharply.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.

Frontal System Suppresses Chongqing Heat A confirmed frontal boundary or rainfall event over the Sichuan Basin on July 3 could pull afternoon temperatures down toward 27°C to 29°C. That scenario would push the 28°C bin above 35% and attract fresh capital to the YES side as forecast models converge on cooler outcomes. Clear Skies Lock In Furnace Temperatures High pressure dominating the Sichuan Basin on July 3 would push probability mass toward the 32°C to 34°C bins. The 28°C contract would fall back toward its opening price of 0.23 as traders rotate into warmer outcome bins and the July climatological baseline reasserts itself. Moderate Cloud Cover Narrows the Distribution A partly cloudy July 3 without heavy rainfall could compress the temperature distribution toward the 27°C to 30°C range. That narrowing would benefit the 28°C and adjacent bins simultaneously, lifting the 28°C contract price as probability mass consolidates away from the extreme warm outcomes. Sudden Large Bet Moves a Thin Order Book With only $4,942 in total volume against $39,470 in liquidity, a single trader placing a few thousand dollars on any adjacent bin could cascade repricing across the entire temperature distribution. This market is thin enough that a coordinated positioning event, not a weather event, could be the dominant price driver before resolution. Key macro factor: Chongqing sits in the Sichuan Basin, a geography that amplifies summer heat through trapped air mass dynamics, making early July temperatures structurally higher than China's national average.
