Chongqing May 28 Temperature: Will 24C Hit?

A sharp momentum surge is driving this market. The 24°C outcome for Chongqing’s highest temperature on May 28 has jumped from 28 cents to 61 cents in a single day, posting one of the steepest intraday moves in this contract’s short history. The market now prices a 60.5% probability that Chongqing’s peak temperature lands exactly at 24°C tomorrow. Here’s what the measurements are telling us: regional forecasting data pointing toward a mild late-May day in the Sichuan Basin is the clearest driver of this repricing.

The market question asks: what will the highest temperature in Chongqing be on May 28, 2026? The 24°C outcome trades at $0.61. The field of alternative outcomes, including 23°C, 25°C, 26°C, 27°C or higher, and several cooler bins down to 17°C or below, collectively price the remaining 39.5% of probability. The contract resolves at 12:00 UTC on May 28. Total volume stands at $36,522, with $30,009 of that changing hands in the last 24 hours alone.

How the Chongqing Temperature Contract Works

This contract resolves YES for the 24°C outcome if the highest recorded temperature in Chongqing on May 28 equals 24°C as measured by the designated resolution source. Each temperature bin is a separate tradeable outcome. The resolution body determines the official daily maximum. Traders holding the 24°C contract collect $1.00 if that exact bin is confirmed. All other outcome holders receive nothing.

• The 24°C outcome trades at $0.61, implying a 60.5% probability of resolution in its favor.
• The aggregate of all alternative outcomes prices at roughly $0.40 combined, reflecting the remaining probability mass.

The alternative outcomes pay out when Chongqing’s daily maximum misses the 24°C bin entirely. Temperatures climbing to 25°C, 26°C, or the 27°C-and-above bucket would benefit those outcome holders. A cooler-than-expected day dropping to 23°C or below would similarly shift value away from the leading outcome. Late May in Chongqing typically sits in a transitional window between the cooler spring and the oppressive summer heat that peaks in July and August, making single-degree precision genuinely difficult to price.

Momentum and Market Conviction

The combined momentum signal here is striking. A 26.5% one-hour price move stacked on top of a 32.5% 24-hour gain, with a trend score of 86.34, points to a rapid consensus shift. The most likely driver is updated short-range forecast data for the Chongqing municipality, which would have become available in the 24 to 48 hours before resolution. Traders appear to have reacted quickly to a model run or observational signal pointing squarely at the 24°C bin.

Total volume of $36,522 is modest for a precision weather market. The $30,009 traded in the last 24 hours represents roughly 82% of all volume, which tells you this conviction is fresh and concentrated in a narrow window. Liquidity of $130,459 is actually deep relative to volume, meaning the order book can absorb new trades without moving the price dramatically. The data doesn’t care about the politics, but thin volume markets like this one can still reprice sharply if a new forecast model run contradicts the current consensus before tomorrow noon UTC.

• The 24°C outcome gained 32.5% in 24 hours, reflecting a rapid shift in trader consensus tied to updated forecast data.
• The one-hour gain of 26.5% suggests the final repricing happened in a compressed window, likely on a specific model update.
• Total volume of $36,522 is low. New forecast data before May 28 resolution could move this market materially.
• Liquidity of $130,459 provides buffer, but the 24-hour volume concentration signals this is a late-breaking trade, not a long-held position.
• Trend score of 86.34 places this among the stronger directional signals in the short-range weather market category.

Lines Analysis: Reading the Chongqing Forecast Signal

The case for the 24°C outcome rests entirely on what short-range numerical weather prediction models are showing for the Sichuan Basin on May 28. Late May in Chongqing typically produces maximum temperatures in the low-to-mid 20s Celsius as the region transitions out of spring. A 24°C reading is a plausible central estimate for a partly cloudy, moderate-wind day in this geography. The speed and scale of the price move suggests at least some traders have access to current model output showing 24°C as the modal forecast.

The risk to the 24°C outcome comes from both directions. A warmer-than-expected day, driven by a strengthening ridge of high pressure or stronger-than-modeled surface heating, pushes probability toward the 25°C or 26°C bins. A cloudier or cooler scenario, perhaps associated with a southward-pushing front or increased precipitation, shifts value toward 22°C or 23°C. The resolution window closes at noon UTC on May 28, which in local Chongqing time is 8:00 PM, well after the daily maximum would be recorded. The market is pricing uncertainty, not science, but the current 60.5% consensus reflects a reasonably tight forecast window.

• Any update to European Centre for Medium-Range Weather Forecasts or NCEP GFS model output for Chongqing on May 28 would directly reprice this contract.
• Observed morning temperatures in Chongqing on May 28 would provide a strong leading indicator of the daily maximum before resolution.
• A significant synoptic shift, such as a cold front or heat dome strengthening over the Sichuan Basin, would invalidate the current forecast consensus.
• The resolution source’s methodology for determining the daily maximum temperature matters. Any ambiguity in the measurement station or observation window could affect resolution.
• Weather market prices in this volume range can move 10 to 20 percentage points on a single updated model run published hours before resolution.

Total volume of $36,522 supports moderate confidence in the current price signal. The data flow over the next 12 to 15 hours, specifically morning observations and the final model runs before the Chongqing daily maximum is recorded, will determine whether the 60.5% consensus holds or breaks. The momentum and order book both favor the 24°C outcome today. Tomorrow’s measurements will settle it.

LINES VERDICT

LEADING OUTCOME: TWENTY-FOUR DEGREES CELSIUS

The rapid price surge from 28 cents to 61 cents in 24 hours reflects a genuine forecast signal, not noise. Short-range model data pointing at the 24°C bin for Chongqing’s May 28 maximum has driven real capital into this outcome.

What the market says: At 60.5% implied probability, traders give the 24°C outcome a clear plurality edge over the full field of alternatives. The contract resolves in less than 24 hours, and the late-breaking volume surge compresses the window for further repricing. New forecast data or early morning observations remain the primary volatility source before the May 28 resolution deadline.

Key unknown: The final short-range model run for the Chongqing municipality, expected in the hours before the daily maximum is recorded on May 28, is the single data point that would most sharply reprice this contract if it diverges from the current 24°C consensus.

Scientific Context

Chongqing sits in the Sichuan Basin, a geography known for its humidity, topographic heat trapping, and extreme summer temperatures. Late May sits in a transitional zone. Daily maximums at this time of year typically range from the low 20s to the high 20s Celsius depending on synoptic conditions. The precision required here, a single-degree resolution bin, means even small forecast errors translate into meaningful probability shifts. This market structure rewards traders with access to current numerical weather prediction output more than those relying on climatological averages alone.

What could move the price before May 28 resolution: Updated GFS or ECMWF model output published May 27 to May 28, observed morning temperatures in Chongqing as a leading indicator, and any reports of unusual synoptic activity over the Sichuan Basin. The contract window is short enough that the next 12 hours are the entire remaining decision horizon.

What is the 60.5% probability actually telling me?

It means the market assigns the 24°C bin a better-than-even chance of being Chongqing’s daily maximum on May 28. With ten outcome bins available, 60.5% is a strong plurality signal, not a near-certainty.

What pays out if 24°C loses?

Any of the nine alternative outcome bins, from 17°C or below up through 27°C or higher, would pay $1.00 to holders of that specific outcome. The 24°C contract would expire worthless.

What single data point would most reprice this contract?

An updated short-range weather model run showing Chongqing’s May 28 forecast shifting to 25°C or 23°C would immediately move capital out of the 24°C bin and into the neighboring outcome.

When does this contract resolve?

Resolution is set for May 28, 2026 at 12:00 UTC. In Chongqing local time, that is 8:00 PM, well after the daily maximum temperature would be recorded.

Is the volume here reliable enough to trust the price?

The $36,522 total volume is modest. The $130,459 in liquidity provides order book depth, but thin-volume weather markets can shift 15 to 20 percentage points quickly if new forecast data contradicts the current consensus before resolution.
