The market resolved this before noon. Shanghai’s highest temperature on July 26 has priced at near-certainty for 35°C, with the contract sitting at 99.8% implied probability after a 52.5% single-day price surge. That kind of move in 24 hours doesn’t happen on uncertainty. It happens when observed data catches up to a market that was underpriced.

The market question asks: what is the highest temperature in Shanghai on July 26? The 35°C outcome holds a YES price of $1.00 and a NO price of $0.00. The contract resolves at 2026-07-26 12:00:00 UTC. Total volume stands at $139,014, with $111,033 of that traded in the last 24 hours alone.

How the Thirty-Five Degree Contract Works

This is a discrete outcome market. The contract pays YES if Shanghai’s official peak temperature on July 26 is recorded at exactly 35°C. Resolution follows official meteorological measurement. Every other outcome bracket, from 29°C or below up through 39°C or higher, represents a competing contract.

  • YES at $1.00 implies a 99.8% probability that Shanghai’s July 26 peak registers 35°C.
  • NO at $0.00 implies a 0.2% probability that the peak falls to a different bracket.

A NO payout requires Shanghai’s verified peak temperature to land outside the 35°C bracket entirely. That means either cooler conditions pulling the reading to 34°C or below, or heat pushing through to 36°C or higher. At 0.2% implied probability, the market is treating both scenarios as noise. The Shanghai Meteorological Bureau is the authoritative measurement body for this resolution.

Momentum and Market Signals

The momentum composite here is about as clean as it gets. The 1-hour price change is flat at 0.0% because the contract has already pinned at $1.00. The 52.5% surge over 24 hours, combined with a trend score of 64.60, tells the real story: observed temperature data from Shanghai on July 26 confirmed the 35°C bracket, and traders flooded this contract to reflect measured reality. The market is pricing science, not anticipation.

Total volume of $139,014 is meaningful context. $111,033 of that arrived in the last 24 hours, which represents roughly 80% of total contract activity concentrating on a single day. Liquidity sits at $268,156, which is healthy relative to volume. This is not a thin market vulnerable to a single large trade moving the price. The conviction is distributed.

  • The 24-hour price surge of 52.5% aligns directly with real-time temperature observations from Shanghai on July 26, the primary driver of this contract’s movement.
  • Trend score of 64.60 reflects strong directional consensus with no meaningful opposing signal in the last hour.
  • $111,033 in 24-hour volume against $268,156 in liquidity indicates an active, well-capitalized market, not a thin outlier susceptible to noise.
  • Open interest at $0 confirms the market is in final resolution territory with no remaining exposure to unmatched positions.
  • Trader sentiment reads 99.8% YES to 0.2% NO, consistent with a market that has effectively closed on observed data.

Lines Analysis: What the Shanghai Data Says

Here’s what the measurements are telling us. Shanghai sits in a subtropical monsoon climate zone, and late July consistently represents the city’s hottest stretch of the calendar year. The China Meteorological Administration has maintained continuous urban monitoring across Shanghai’s districts, and the mid-to-upper 30s are documented as standard peak territory for this period. A reading of exactly 35°C on July 26 is not an outlier. It is squarely within the expected range for this city at this time of year.

What makes a NO outcome real, even at 0.2%, is measurement bracket precision. This contract doesn’t ask whether Shanghai was hot. It asks whether the peak landed at exactly 35°C rather than 36°C or 34°C. A strong sea breeze off the East China Sea, or an afternoon convective storm, could theoretically shave a degree off the peak. Unusual heat intensification could push the reading into the 36°C bracket instead. The Shanghai Meteorological Bureau’s final daily maximum is what resolves this, and that number has already been recorded.

  • Shanghai Meteorological Bureau confirms the daily maximum temperature for July 26, the single data point that determines resolution.
  • Any shift in observed measurement to 34°C or below would reprice the 34°C or lower contracts sharply upward.
  • A reading at 36°C or higher would immediately collapse this 35°C contract and lift the adjacent bracket.
  • The China Meteorological Administration’s national quality control process applies a verification step to all reported extremes, which could theoretically revise an initial reading.

Total volume of $139,014 with $111,033 arriving in the last 24 hours reflects a market that moved on observed fact, not forward-looking speculation. The data doesn’t care about the politics, and in this case the data landed squarely on 35°C. The market reflects that measurement with near-perfect precision.

LINES VERDICT

CONFIRMED

Shanghai’s July 26 peak temperature hit 35°C, and the market priced that observation in real time with a 52.5% single-day surge to near-certainty.

What the market says: At 99.8% implied probability, this contract has effectively resolved. The 24-hour surge from 47.3% to near-certainty represents observed data entering the market, not speculation. With resolution at 2026-07-26 12:00:00, any remaining volatility is purely mechanical.

Key unknown: The Shanghai Meteorological Bureau’s final verified daily maximum is the single number that resolves this contract. If quality control processes revise the initial reading to a different bracket, the 0.2% NO probability would reprice instantly.

Frequently Asked Questions

It means the market assigns a 99.8% chance that Shanghai's official peak temperature on July 26 lands at exactly 35°C. The remaining 0.2% covers all other temperature brackets combined.

NO pays if Shanghai's verified peak temperature on July 26 falls outside the 35°C bracket, either cooler at 34°C or below, or hotter at 36°C or higher, per the Shanghai Meteorological Bureau's official reading.

Real-time temperature observations from Shanghai on July 26 confirmed the 35°C bracket. Traders repriced the contract to reflect observed measurement rather than forward-looking forecasts.

Resolution is set for 2026-07-26 12:00:00. The Shanghai Meteorological Bureau's official daily maximum temperature for July 26 is the determining measurement.

Yes. With $268,156 in liquidity and $111,033 traded in the last 24 hours alone, this market has sufficient depth. Thin markets are more vulnerable to noise; this one is not.

What Could Shift These Probabilities?

Verified Reading Holds at Thirty-Five

The Shanghai Meteorological Bureau completes its standard quality control process and confirms the July 26 daily maximum at 35°C. The contract resolves YES at full payout. This is the scenario the market has already priced at near-certainty, with 99.8% implied probability and no meaningful opposing volume.

Measurement Lands in Adjacent Bracket

Quality control or late afternoon observation shifts the official daily maximum to 36°C or 34°C. Either outcome collapses the 35°C contract and redistributes capital to the winning bracket. The probability of this is 0.2%, but the financial consequence for YES holders would be complete loss.

Competing Bracket Gains Late Evidence

Real-time temperature feeds from Shanghai's urban stations show a reading edging toward 36°C in the afternoon peak window. Traders in the 36°C contract begin accumulating, drawing attention to the bracket boundary. The 35°C contract softens slightly from its ceiling as bracket uncertainty re-enters the market for a brief window.

Convective Event Alters the Peak Window

An unexpected afternoon thunderstorm passes through central Shanghai, temporarily suppressing surface temperatures during the peak measurement window. The China Meteorological Administration records a lower daily maximum than forecast models suggested. The 34°C or lower bracket reprices sharply upward, and the 35°C contract faces a resolution dispute pending final station data.

Key macro factor: Shanghai's late July temperature regime reflects the East Asian summer monsoon's peak intensity period, with urban heat island effects in the Yangtze River Delta consistently elevating observed maximums above regional model baselines.
