STATISTICAL FAVORITE: Qingdao's July climatology supports 31°C as the single most likely daily high, but eleven competing buckets keep YES at a minority 31 percent. Market probability: 31%.

Two days out from resolution, the Qingdao temperature market sits at 31 percent for a 31°C daily high on July 6. That number is neither a confident bet nor a dismissal. It reflects a genuinely fragmented forecast landscape where eleven outcome buckets split trader capital across a wide range. The market is pricing uncertainty, not science.

The market question asks whether Qingdao’s highest temperature on July 6 will reach exactly 31°C. The YES price sits at $0.31, the NO price at $0.69, and the contract resolves at noon local time on July 6, 2026. Total volume is $1,201, all of it traded in the last 24 hours.

How the 31°C Contract Works

A YES resolution requires Qingdao’s official maximum temperature on July 6 to land at exactly 31°C, not 30°C, not 32°C. The measurement body and resolution source is the market operator, drawing on official meteorological records. If the daily high comes in one degree either direction, YES holders lose. That precision is the defining risk of this contract.

  • YES ($0.31, implied 31%): Qingdao’s July 6 high lands at exactly 31°C.
  • NO ($0.69, implied 69%): The daily high lands at any other temperature, whether cooler or warmer.

The NO contract pays out across ten alternative outcomes, from 25°C or below all the way to 35°C or higher. A forecast miss of even one degree in any direction delivers the same result for NO holders. The Chinese Meteorological Administration’s Qingdao station typically records a daily high in a single integer, so the outcome is binary against a precise threshold. The question is not whether Qingdao is hot in early July. It almost always is. The question is whether meteorological conditions on that specific day land on exactly 31°C.

Momentum and Market Signals

The momentum composite here is thin but directional. The 1-hour price change of +0.5 percent, combined with a trend score of 39.39, points to mild upward pressure on the YES price. No 24-hour comparison is available, which limits confidence in reading sustained direction. The most likely driver is short-range forecast data coming into alignment as July 6 approaches.

Total volume is $1,201, and all of it arrived in the last 24 hours. Liquidity sits at $18,203, which is healthy relative to volume. But volume this thin means a single moderate-size trade can move the price sharply. Here’s what the measurements are telling us: this market is lightly traded and sensitive to any new forecast signal.

  • The YES price moved +0.5% in the last hour, suggesting marginal fresh positioning toward the 31°C outcome.
  • The 24-hour volume of $1,201 is below the threshold where price movements carry strong conviction.
  • Liquidity at $18,203 is deep enough to absorb new bets without major slippage, but volume is too thin to treat current pricing as settled consensus.
  • The trend score of 39.39 sits in mildly bearish territory, consistent with a market that leans NO but has not committed strongly.
  • Open interest is $0, meaning no outstanding contracts are currently held, which underscores the market’s early-stage positioning.

Lines Analysis: Qingdao’s July Temperature Range

Early July is solidly warm in Qingdao. The city sits on the southern coast of the Shandong Peninsula, and its marine climate moderates summer extremes relative to inland northern China. Historical July daily highs in Qingdao cluster in the 28°C to 33°C range, with 30°C to 32°C being the most common band. That makes 31°C a reasonable central estimate, which is exactly why the market assigns it the highest single-outcome probability at 31 percent.

What keeps the YES price from climbing further is pure precision risk. A maritime influence pushing sea breezes onshore could cap the high at 29°C or 30°C. A ridge of high pressure settling over the region could push the high to 32°C or 33°C. Chinese Meteorological Administration forecasts for Qingdao on July 6 are currently within the 30°C to 32°C range, which means two adjacent outcomes are eating into the probability mass that would otherwise concentrate on 31°C. The data doesn’t care about the politics of which bucket wins. It just resolves at the number the thermometer hits.

  • Short-range NWP models (ECMWF, GFS) updating through July 5 will be the clearest pricing signal.
  • A sustained onshore wind pattern on July 5 and 6 would bias the high toward 29°C or 30°C.
  • A heat dome or blocking high over northern China would push the high toward 32°C or 33°C.
  • Chinese Meteorological Administration official Qingdao forecast updates, expected July 5, carry the most resolution-relevant data.
  • Any typhoon or tropical disturbance in the Yellow Sea would introduce wild variability across all outcome buckets.

The $1,201 in total volume reflects a market that is speculative rather than deeply informed. The 31 percent implied probability is defensible given Qingdao’s July climatology, but eleven competing outcomes mean no single bucket commands conviction. The data favors a YES outcome in the statistical sense that 31°C is the most probable single value, but the NO side holds 69 percent precisely because the probability mass is spread so thin.

LINES VERDICT

STATISTICAL FAVORITE, FRAGMENTED FIELD

Qingdao’s July climatology makes 31°C the single most likely daily high for July 6, but eleven competing outcome buckets distribute probability so widely that 31 percent YES is both the market leader and a distinctly minority position.

What the market says: At 31 percent implied probability, the market treats 31°C as the most credible single outcome while assigning a combined 69 percent to everything else. With resolution two days out and volume under $1,500, this price can shift sharply on a single updated forecast.

Key unknown: The Chinese Meteorological Administration’s official Qingdao forecast for July 6, expected to update on July 5, is the single data point most likely to reprice this contract before resolution.

Frequently Asked Questions

It means traders assign a 31 percent chance that Qingdao's July 6 daily high lands at exactly 31°C. Ten other temperature outcomes share the remaining 69 percent probability.

NO pays out if Qingdao's July 6 high is anything other than 31°C, including 30°C, 32°C, or any other temperature bucket. One degree of difference in any direction resolves NO.

Short-range weather model updates from ECMWF or GFS, and the Chinese Meteorological Administration's official Qingdao forecast for July 6, expected July 5, are the primary price-moving signals.

The contract resolves at noon local time on July 6, 2026, based on the official recorded maximum temperature for Qingdao that day.

Volume this thin means the 31 percent price reflects limited trader conviction. A single moderate trade could shift the price noticeably before the July 6 resolution.

What Could Shift These Probabilities?

Forecast Convergence on 31°C

If the ECMWF and GFS models both converge on a 31°C high for July 6 in their July 5 runs, traders will concentrate bids on this bucket. The YES price could climb toward 40 to 45 percent as forecast certainty tightens. Chinese Meteorological Administration confirmation of a 31°C official forecast would accelerate that move.

Heat Ridge Pushes High to 32°C or Above

A strengthening anticyclone over northern China on July 5 could push Qingdao's July 6 high into the 32°C to 33°C range. That scenario would drain probability from the 31°C bucket and redistribute it to warmer outcomes. YES price would fall sharply toward 15 to 20 percent.

Marine Layer Caps the High at 31°C

Onshore Yellow Sea breezes moderating afternoon heat could land Qingdao's high at exactly 31°C, the temperature at which sea breezes and afternoon solar heating reach equilibrium in early July. This is the most physically plausible YES pathway and the scenario the current 31 percent price is essentially modeling.

Tropical Disturbance Scrambles All Forecasts

A tropical system or typhoon tracking toward the Yellow Sea by July 5 would introduce cloud cover, precipitation, and wind shear that could suppress Qingdao's high to 27°C or below, or trigger anomalous warmth ahead of the system. Either scenario would void the current probability distribution entirely and crash the YES price.

Key macro factor: Early July 2026 falls within a neutral to weak La Nina pattern, which reduces the likelihood of extreme heat anomalies over coastal northern China but does not materially shift Qingdao's July climatological baseline.
