The market prices a 28% chance that the daily high lands exactly at 31°C. That is a minority view in a crowded field of competing temperature outcomes, from 23°C or below all the way to 33°C or higher. The market question asks: what will the highest temperature in Qingdao be on July 10, 2026? The 31°C outcome trades at $0.28 YES and $0.72 NO. Total volume sits at $4,329, with all of that arriving in the last 24 hours. The market resolves at 2026-07-10 12:00:00. How the 31°C Contract Works A YES resolution means Qingdao’s official daily high temperature on July 10 lands exactly at 31°C. A NO resolution covers every other outcome: any temperature above or below that specific reading. The market resolves based on the official recorded high for that date. YES ($0.28, 28% implied probability): Qingdao’s July 10 high is exactly 31°C.NO ($0.72, 72% implied probability): The daily high lands at any temperature other than 31°C. The NO side covers ten other outcome buckets, from 23°C or below up to 33°C or higher. That structural reality alone suppresses any single outcome’s probability. For NO to pay out here, Qingdao’s high simply needs to miss 31°C by any margin. That is the base case, and the market reflects it clearly. Sponsored Partner Momentum and Market Signals The 1-hour price change of +2.5% combined with a trend score of 39.76 points to mild upward pressure on the 31°C outcome. That move is small in absolute terms. But given thin volume, even modest new trades shift the price noticeably. Total volume is $4,329, all of it within the last 24 hours. Liquidity is $46,851, which is deep relative to the volume traded. That liquidity depth means the order book can absorb larger trades without dramatic price swings. Still, at under $1M in total volume, this market is thin. A single informed trade in the next 48 hours could reprice the 31°C outcome meaningfully. The 1-hour move of +2.5% with a trend score below 40 signals cautious momentum, not a strong directional shift.All $4,329 in volume arrived in the last 24 hours, making this an extremely young market with limited price discovery.Liquidity of $46,851 exceeds volume by a factor of ten, meaning the book is wide but lightly touched.Thin volume below $1M means price can move sharply on any fresh weather data or forecast update before July 10.The 1-hour change of +2.5% is the only momentum signal available. No 24-hour trend exists to compare against. Lines Analysis: Qingdao Temperature Outlook Qingdao in early July sits in a transitional weather zone. The city on China’s eastern coast typically sees July highs ranging from the upper 20s to the low 30s Celsius. The 31°C outcome sits near the middle of that historical range, which explains why it holds the highest single-outcome probability in the field. That said, 28% is still a minority view. Seven other outcomes collectively hold 72% of the probability mass. What makes NO real here is simple arithmetic. Eleven outcomes compete for the correct temperature reading. Even if 31°C is the modal outcome, the probability of any other specific temperature reading is close to or higher than 28%. Qingdao’s coastal position means marine air can suppress highs below 30°C on days with easterly winds, while inland pressure systems can push highs toward 33°C or above. The specific outcome of exactly 31°C requires both a warm enough airmass and a cap on daytime heating. Neither condition is guaranteed two days out. The next official weather forecast update for Qingdao before July 10 is the single most important signal for this market.A forecast showing a consistent 31°C high across multiple models would push YES toward 35-40%.A forecast showing 30°C or 32°C would bleed probability away from this outcome toward adjacent buckets.Any significant weather system, typhoon influence, or cold front would reprice multiple outcomes simultaneously.Thin volume means a single large trade following a forecast update could shift YES price by 5-10 percentage points. Total volume of $4,329 is very light. The data favors NO structurally because of outcome fragmentation, but the 31°C bucket is the strongest single candidate. Here’s what the measurements are telling us: without a locked forecast, this market is pricing uncertainty, not science. LINES VERDICT STRUCTURALLY UNCERTAIN, FAVORS NO Eleven competing outcomes make any single temperature reading a long shot by construction. The 31°C bucket holds the field’s leading probability, but 28% is not conviction. The market is pricing the full range of plausible July temperatures for a coastal Chinese city, not a settled forecast. What the market says: At 28% implied probability, traders see 31°C as the likeliest single outcome but still assign nearly three-to-one odds against it. With resolution on July 10, 2026, any updated forecast in the next 48 hours can shift this price significantly. Key unknown: The official National Meteorological Center of China forecast for Qingdao on July 9 or 10 is the single data point that will reprice this contract. A pinned forecast at 31°C narrows the field. Anything else widens it. Frequently Asked QuestionsWhat does 28% probability mean for the 31°C outcome?It means traders assign roughly a one-in-four chance that Qingdao's July 10 high lands exactly at 31°C. Ten other temperature outcomes compete for the remaining 72% of probability.What pays out on the NO side of this contract?Any temperature other than exactly 31°C resolves NO. That includes every outcome from 23°C or below up to 33°C or higher, covering ten alternative buckets.What data release would move this market most before July 10?An updated official forecast from China's National Meteorological Center pinning Qingdao's July 10 high at or near 31°C would push YES higher. A forecast showing 30°C or 32°C would shift probability to adjacent outcomes.When does this market resolve?The market resolves on July 10, 2026, at 12:00 UTC, based on the official recorded high temperature for Qingdao on that date.Is the volume and liquidity reliable here?Total volume is only $4,329, making this a thin market. Liquidity of $46,851 is deep relative to volume, but thin trading means a single large trade could shift the YES price by several percentage points.How is the Smart Money Index calculated?We aggregate the live positions of the top 50 Polymarket whales (ranked by 30-day tracked volume) into one composite reading per market.

Forecast Locks In at 31°C China's National Meteorological Center releases a consistent 31°C forecast for Qingdao on July 9 or early July 10. Multiple weather models align on the same reading. Traders reprice YES from 28% toward 40% or higher as forecast uncertainty collapses in the final 24 hours before resolution. Adjacent Outcomes Capture Probability Updated forecasts show Qingdao's July 10 high trending toward 30°C or 32°C. Probability mass migrates from the 31°C bucket to neighboring outcomes. YES drops below 20% as the market reflects a shifted central forecast and the 31°C outcome becomes a tail scenario. Weather Models Converge Late Early forecasts show wide spread across 29°C to 33°C, keeping 31°C at 28%. Late-breaking model consensus on July 9 narrows the range and re-centers on 31°C. Thin liquidity amplifies the move, and YES climbs back toward the high end of its recent range near 32 cents. Unexpected Weather System Hits Qingdao A fast-moving cold front or residual typhoon circulation reaches Qingdao's coast ahead of July 10, pushing the daily high below 28°C or above 33°C. Probability collapses out of the central temperature buckets entirely. The 33°C or higher and 27°C or below outcomes spike while 31°C drops sharply. Key macro factor: Qingdao's position on the Yellow Sea means summer temperature variability is driven by the interaction between the East Asian summer monsoon and coastal marine air, both of which can shift daily highs by three to five degrees Celsius on short notice.
