The Sichuan Basin locks in summer warmth, and July is historically the city’s hottest month. The market is currently pricing a 26% chance that July 6 peaks at exactly 36°C. That is not a bet on whether Chengdu will be hot. It is a bet on a single-degree precision window inside one of China’s most reliably sweltering urban environments. The market question asks: what is the highest temperature in Chengdu on July 6? The 36°C outcome trades at 0.26 YES and 0.74 NO. The market resolves on July 6, 2026, at 12:00 UTC. Total volume stands at $4,353, all of it placed within the last 24 hours. This is a brand-new market with thin liquidity relative to the precision it demands. How the Contract Works: Exact-Degree Resolution on a Multi-Outcome Market This contract resolves YES if Chengdu’s official daily high on July 6 lands precisely at 36°C. Every other outcome, from 32°C or below up to 42°C or higher, is a separate tradeable contract. The resolution body is the official meteorological record for Chengdu, likely sourced from China Meteorological Administration station data. YES (36°C peak on July 6) trades at 0.26, implying a 26% probability.NO (any other peak temperature) trades at 0.74, implying a 74% probability. The NO outcome pays when Chengdu’s July 6 high lands anywhere other than 36°C. That means 35°C, 37°C, 38°C, or higher all count as NO for this specific contract. The probability is spread across more than ten discrete outcomes, so no single bucket commands a majority. The 36°C window is competitive precisely because it sits near the climatological average for early-July Chengdu highs. Momentum and Market Signals: Early Movement in a Thin Book Sponsored Partner Momentum is slightly negative. The 36°C contract dropped 1.5% in the last hour, with a trend score of 38.96 out of 100, suggesting soft but real directional pressure toward lower probabilities. The most likely driver is early forecast data pointing toward temperatures slightly outside the 36°C window, though no single data release has dominated trading today. Total volume is $4,353, all from the last 24 hours. Liquidity sits at $32,976, which is healthy relative to the volume traded. Even so, this market is well below the $1 million threshold for high-confidence signals. A single large trade or a fresh weather forecast update could move the 36°C contract price sharply before the July 6 close. The 1-hour price drop of 1.5% and trend score below 40 together signal mild selling pressure on the 36°C outcome.Liquidity at $32,976 is adequate for the current volume but thin enough that new meteorological data would reprice the contract quickly.The 24-hour volume equaling total volume confirms this contract opened very recently, limiting historical price signal value.No whale trades have been recorded, so price action reflects retail-level conviction rather than informed institutional positioning.Related markets on 2026 temperature rankings price at 65%, consistent with an expectation of continued above-average warmth across Asia this summer. Lines Analysis: Chengdu Basin Heat and the One-Degree Problem The case for 36°C rests on Chengdu’s climatological base. Early July highs in Chengdu cluster between 33°C and 37°C, with 35°C to 37°C being the most frequent range. The 36°C bucket captures a meaningful slice of that distribution. The Sichuan Basin geography, surrounded by mountains on three sides, suppresses wind and amplifies radiative heating. A day without significant cloud cover or precipitation pushes Chengdu well into the mid-30s range. What makes this contract hard is the precision requirement. Forecasts for July 6 would need to pin the high at exactly 36°C to drive strong YES buying. Any model run showing 37°C or 38°C pulls money toward the higher buckets. The recent 1.5% price decline suggests forecasts may be trending slightly warmer, shifting probability mass toward 37°C or 38°C contracts. Heat wave patterns across China in 2025 and early 2026 have repeatedly pushed Sichuan Basin highs into the upper 30s, which adds pressure to the higher-temperature contracts. A China Meteorological Administration forecast update showing 36°C to 37°C for July 6 would support YES buying in this contract.Any synoptic pattern showing a cold front or precipitation event before July 6 would shift probability toward 34°C or 35°C contracts.Persistent heat dome conditions over the Sichuan Basin through July 5 would pull probability mass toward 38°C or higher outcomes.The official daily high measurement, not a forecast, determines resolution. Late-day temperature spikes matter.No official CMA forecast data for July 6 has been priced into this contract yet, meaning the next model run is the primary repricing catalyst. The $4,353 in total volume is too thin to treat as a strong consensus signal. The market is pricing meteorological uncertainty across a multi-outcome structure, and no single bucket has enough volume to anchor conviction. The data currently tilts slightly away from 36°C and toward the warmer outcomes, but this remains a genuinely open question until July 5 forecast data arrives. LINES VERDICT UNCERTAIN WITH SLIGHT DOWNWARD DRIFT The 36°C contract sits in a plausible temperature range for early-July Chengdu, but the precision required for resolution makes this a probabilistic long shot even when conditions favor it. Recent price action suggests modest flow toward higher-temperature outcomes. What the market says: At 26% implied probability, this contract reflects that 36°C is a realistic but far-from-certain outcome in a multi-bucket market. Thin volume means this price is volatile and will reprice sharply on any updated July 6 forecast before the resolution deadline. Key unknown: The China Meteorological Administration forecast for July 6 issued on July 4 or July 5 is the single event that would move this contract most dramatically. A model consensus around 36°C to 37°C would push YES higher. A forecast above 37°C would drain probability from this bucket fast. Scientific Context: Chengdu Basin Climatology and July Heat Chengdu’s July climatological average high runs near 31°C to 32°C by long-term records, but observed extremes in recent years have pushed significantly above that baseline. The Sichuan Basin effect, combined with urban heat island warming in a city of over 20 million, means July 6 temperatures in the mid-to-upper 30s are well within the range of recent experience. The multi-outcome structure of this market reflects real meteorological spread: July days in Chengdu genuinely can land anywhere from the low 30s to above 40°C depending on synoptic conditions. Frequently Asked QuestionsWhat does 26% probability mean for the 36°C outcome?It means the market estimates a roughly one-in-four chance that Chengdu's official July 6 high lands at exactly 36°C. The remaining 74% is spread across all other temperature outcomes, from 32°C or below up to 42°C or higher.How does the NO contract pay out here?The NO contract on the 36°C outcome pays if Chengdu's July 6 official high is any temperature other than 36°C. That includes both cooler outcomes like 35°C and warmer ones like 37°C or above.What data or event would move this contract's price most?A China Meteorological Administration forecast update for July 6 issued on July 4 or 5 is the primary catalyst. A model consensus pinning the high at 36°C would push YES sharply higher. A forecast above 37°C would pull money toward warmer buckets.When does this market resolve?The market resolves on July 6, 2026, at 12:00 UTC, based on the official recorded daily high temperature in Chengdu. The resolution source is the official meteorological record for that date.Is the $4,353 in volume enough to trust this price?No. Total volume is well below $1 million, meaning liquidity is thin and the price can shift dramatically on a single new forecast or large trade.

Forecast Locks In at 36°C If China Meteorological Administration model runs issued July 4 or 5 consistently show a July 6 Chengdu high of 36°C, YES buyers would likely push the contract price well above 30%. Partly cloudy skies with light winds on July 6 would support a precise landing in the mid-30s range without overshooting into 37°C or 38°C territory. Heat Dome Pushes Temperatures Above 37°C Persistent high-pressure conditions over the Sichuan Basin through July 5 would pull probability mass toward the 37°C, 38°C, and higher buckets. Recent regional heat patterns in 2025 and early 2026 have repeatedly pushed Chengdu above historical norms. If that pattern holds, the 36°C contract loses ground fast. Cloud Cover or Brief Precipitation Trims the High A passing weather system or afternoon cloud development on July 6 could cap the daily high below 37°C, keeping the 36°C bucket competitive. If forecasts shift toward a partly cloudy or unstable July 6 pattern, money would flow back into the 35°C and 36°C contracts from the higher-temperature outcomes. Late-Day Temperature Spike Reshapes the Record Chengdu's official daily high is recorded over the full calendar day. An unexpectedly hot late afternoon, driven by urban heat island effects or sudden clearing skies, could push the observed high above forecast consensus by one or two degrees. That kind of late-day spike has caught forecasters and markets off guard in past Sichuan Basin heat events. Key macro factor: Above-average warmth across eastern Asia in summer 2026, consistent with the 65% probability assigned to 2026 ranking among the hottest years on record, creates a background environment that tilts Chengdu July highs toward the upper end of the historical distribution.
