Chongqing May 19 Temperature: 25C at Twenty Percent

Chongqing sits in a river basin that turns May heat into something complicated. The market on May 19’s peak temperature has settled into a fragmented field, with six outcome buckets splitting trader conviction across a wide range. The 25°C outcome carries a 20.5% implied probability. That number reflects genuine meteorological uncertainty, not a strong signal in either direction.

Total volume on this contract stands at $2,679. That is thin. Liquidity is $2,341, meaning a single meaningful trade could reprice this contract sharply before the May 19 resolution. The 24-hour price change on the 25°C outcome dropped 6.0%, and the trend score of 31.81 points to fading conviction. The market is pricing uncertainty, not science.

How the Chongqing Temperature Contract Works

This contract resolves YES if Chongqing’s recorded daily high temperature on May 19, 2026 lands exactly at 25°C. Resolution occurs at 2026-05-19 12:00:00. The resolution source is the market itself, drawing on verified meteorological observation for Chongqing on that date.

• YES (25°C outcome): priced at $0.21, implying a 20.5% probability that the daily high lands at exactly 25°C.
• NO (all other outcomes): priced at $0.80, implying a 79.5% probability that the daily high falls on a different bucket: 22°C, 24°C, 28°C, 29°C, or 30°C or higher.

The NO side wins when Chongqing’s May 19 peak temperature misses the 25°C mark. Given the six-way split across outcomes, the probability is structurally distributed. Chongqing’s May climate historically produces highs ranging from the low twenties to well above thirty degrees Celsius, depending on synoptic conditions. The 25°C bucket is one of the narrower targets in a wide field.

Momentum and Market Signals

The composite signal here is weak and slightly negative. A flat one-hour change combined with a 6.0% drop over 24 hours and a trend score of 31.81 suggests traders are quietly stepping away from the 25°C outcome, not piling in. No single data release or weather event appears to have triggered the move. It reads like gradual repositioning toward adjacent temperature buckets as forecast models update.

Volume of $2,679 total and $5,674 in 24-hour volume flags a thin market. When liquidity sits at $2,341, the order book is shallow enough that any informed trader with a fresh meteorological read could move the price materially before resolution tomorrow.

• The 25°C outcome has dropped 6.0% in 24 hours, a mild bearish signal in a low-liquidity environment.
• The trend score of 31.81 sits below the midpoint of a standard 0-100 range, confirming weakening momentum for this bucket.
• Six competing outcome buckets mean probability is inherently fragmented. No single outcome dominates.
• Thin liquidity means any price reference here should be treated as directional, not precise.
• The 1-hour change is flat, suggesting the 24-hour slide has stabilized for now.

Lines Analysis: Chongqing’s May Forecast Window

Chongqing’s mid-May climate is transitional. The city sits at roughly 29°N latitude in a humid subtropical zone. May highs in the basin commonly range from 23°C to 32°C, with the lower end of that range more likely during cloud-dominant or rain-influenced days. The 25°C bucket sits at the cooler end of that range. For this outcome to pay, conditions on May 19 would need to be mild and overcast without pushing into the cooler 22-24°C range or warmer 28°C-plus territory.

What makes the NO side real is simple arithmetic. Five other outcome buckets absorb 79.5% of the implied probability. Chongqing’s weather models for late May 2026 would need to produce a surprisingly narrow and precise forecast landing exactly at 25°C for this contract to resolve YES. The adjacent 24°C and 28°C buckets represent meaningful competing claims on where the high actually lands.

• China Meteorological Administration forecasts for Chongqing on May 19 are the single most important data input before resolution.
• Any shift in regional pressure systems moving through Sichuan Basin overnight could push the high into the 28°C-plus range.
• A persistent cloud cover or precipitation event on May 19 would favor the lower buckets (22°C, 24°C) at the expense of 25°C.
• The 30°C-or-higher bucket gains relevance if current La Nina transitional conditions accelerate warming ahead of the regional monsoon onset.
• Volume spikes in adjacent buckets (24°C or 28°C) before resolution would signal traders are repositioning away from 25°C.

At $2,679 in total volume and 20.5% implied probability, the 25°C outcome is a minority position in a fragmented field. The data slightly favors the broader NO position, given how many competing outcomes exist. Here’s what the measurements are telling us: no single bucket commands strong conviction, and the market is distributing probability across a realistic meteorological range for Chongqing in mid-May.

LINES VERDICT

Fragmented Field, Thin Market

The 25°C outcome holds a modest minority share in a six-way split. Chongqing’s May 19 high is genuinely uncertain, and the market reflects that uncertainty without strong directional conviction in any single bucket.

What the market says: A 20.5% probability means traders see roughly one-in-five odds for an exact 25°C daily high. With resolution at 2026-05-19 12:00:00 and thin liquidity, this price can shift sharply on any updated regional forecast before markets close.

Key unknown: The China Meteorological Administration’s May 19 Chongqing forecast, updated through the overnight hours before resolution, is the single data point that would reprice every bucket in this contract.

Scientific Context

Chongqing’s urban heat island effect and basin geography make precise daily high forecasting difficult at any range beyond 48 hours. The city’s May climatology shows a standard deviation of several degrees Celsius around mean daily highs, which is why a six-bucket market structure makes sense. The data doesn’t care about the politics: meteorological precision at the one-degree level, resolved at a single point in time, is a hard target to hit. That structural difficulty is baked into the 20.5% price for this specific outcome.

Frequently Asked Questions

• What does 20.5% probability mean here? It means the market assigns roughly a one-in-five chance that Chongqing’s May 19 daily high lands exactly at 25°C, based on current trader positioning across six competing outcome buckets.
• What does the NO contract pay on? The NO side at $0.80 pays out if Chongqing’s May 19 high lands on any outcome other than 25°C, including 22°C, 24°C, 28°C, 29°C, or 30°C or higher.
• What data event would move this price? An updated China Meteorological Administration short-range forecast for Chongqing on May 19 is the most direct input. Regional synoptic weather maps showing pressure and cloud cover overnight would be the secondary signal.
• When does this contract resolve? Resolution is set for 2026-05-19 12:00:00, based on the recorded daily high temperature in Chongqing on May 19, 2026.
• Is volume and liquidity reliable here? No. Total volume of $2,679 and liquidity of $2,341 make this a thin market. Prices can move sharply on small trades, and the implied probability should be treated as directional rather than precise.
