Taipei bakes in late July. The question this market is asking is not whether it will be hot, but whether the daily maximum lands on a single one-degree target: exactly 36°C. The market prices that outcome at 37% probability, meaning traders see it as the most likely single outcome among ten choices but still expect the mercury to miss that mark more often than not. That’s the tension here: high confidence that it’s hot, real uncertainty about where exactly the needle stops.

The market question asks for the highest temperature in Taipei on July 25, 2026, resolving at noon UTC on July 25. The YES price sits at 0.37 and the NO price at 0.63. Total volume is $64,304, with $42,968 traded in the last 24 hours. The market resolves tomorrow.

How the Thirty-Six Degree Contract Works

This is an outright outcome market with ten possible temperature buckets. YES pays if the official Taipei daily maximum on July 25 equals exactly 36°C. NO covers every other outcome: 35°C, 37°C or higher, 34°C, or anything below. The resolution source is market resolution, meaning the platform determines the official high from a recognized weather data provider for Taipei.

  • YES (36°C): priced at 0.37, implying 37% probability.
  • NO (any other outcome): priced at 0.63, implying 63% probability.

A NO payout happens when Taipei’s recorded high lands anywhere except 36°C. That means a cooler marine influence pushing the max to 34°C or 35°C pays NO. So does an exceptional heat surge pushing past 37°C. Both weather patterns are plausible in late July, which is why the spread favors NO by a wide margin. The market is pricing the imprecision of hitting a single degree, not skepticism that it’s hot.

Momentum and Market Signals

The combined momentum signal is mildly bullish but unconvincing. The 36°C contract dropped 4.5% in the last hour but gained 7.5% over the prior 24 hours. The trend score of 51.96 sits just above neutral. That pattern suggests traders pushed into YES positions during the trading session but pulled back as the resolution window tightened. The most likely driver is forecast updates: late-day weather model runs for Taipei that may have shifted the probability distribution slightly away from 36°C.

Total volume of $64,304 is modest for a one-day resolution market. The 24-hour volume of $42,968 represents roughly two-thirds of all activity, which is consistent with a market that woke up as the resolution date approached. Liquidity stands at $159,080, which is healthy relative to volume. Thin markets can reprice sharply on a single large trade, but this one has enough depth to absorb normal activity. With resolution in less than 17 hours, any remaining price movement will track real-time forecast updates.

  • The 24-hour price gain of 7.5% followed by a 1-hour drop of 4.5% signals late-session hedging against the 36°C outcome.
  • Trend score of 51.96 puts momentum just above neutral, consistent with a market in wait-and-see mode ahead of resolution.
  • Liquidity at $159,080 is strong relative to volume, meaning the order book can handle new information without wild price swings.
  • Volume concentration in the last 24 hours confirms this market activated as the resolution date arrived, not weeks in advance.
  • Related markets show no correlation with Taipei temperature dynamics, so external market signals offer no useful cross-check here.

Lines Analysis: Taipei’s July Heat Distribution

Late July in Taipei is consistently hot. The city sits in a humid subtropical climate, and July daily highs regularly fall between 33°C and 38°C. The Central Weather Administration of Taiwan records official daily extremes, and historical patterns show 35°C to 37°C as the most common range for peak summer days. The market is essentially pricing whether the heat lands in the center of that range or drifts to either edge.

The data doesn’t care about the politics, and here the data is straightforward: 36°C is the modal guess, but weather forecasting at one-degree resolution 12 to 24 hours out carries meaningful uncertainty. A stronger southwest monsoon surge could push the high toward 38°C or 39°C. An afternoon cloud layer or brief rain event could cap the max at 34°C or 35°C. Both scenarios pay NO. The 63% NO price is the market acknowledging that precision is hard, not that heat is unlikely.

  • Taiwan Central Weather Administration data will determine resolution. Any official high reading outside 36°C closes this contract as NO.
  • Southwest monsoon intensity on July 25 is the primary meteorological variable. A stronger flow means higher highs.
  • Afternoon convective activity, which is common in Taipei in July, can cap daily maxima even when morning temperatures run high.
  • Numerical weather prediction models updated tonight and tomorrow morning will be the last major information event before resolution.
  • Urban heat island effects in central Taipei consistently push recorded highs above surrounding rural areas, adding upward pressure to the forecast.

The $64,304 total volume reflects genuine trader interest in a granular weather outcome, but this is not a deep liquid market by prediction market standards. The data favors the broader NO position simply because ten possible outcomes split probability, and even the most likely single outcome rarely exceeds 40% in a market this fragmented. The market is pricing uncertainty, not science.

Lean NO, But Watch the Forecast

Taipei almost certainly sees a hot day on July 25. The market’s real question is whether the thermometer stops exactly at 36°C, and the mathematical reality of ten outcome buckets keeps YES structurally capped below 50%.

What the market says: A 37% implied probability means traders see 36°C as the single most likely outcome, but still expect a two-in-three chance the temperature lands somewhere else. With less than 17 hours to resolution, any shift in forecast models could reprice this contract quickly.

Key unknown: The final numerical weather prediction model runs tonight for Taipei will be the last major data point before the market closes. A model consensus shift toward 35°C or 37°C would push YES lower; a tight cluster around 36°C would push it higher.

Frequently Asked Questions

Traders collectively estimate a 37% chance Taipei's official daily high on July 25 equals exactly 36°C. That makes it the single most likely outcome, but still a minority probability across ten possible temperature buckets.

NO pays if Taipei's recorded high on July 25 lands at any temperature other than 36°C, including 35°C, 37°C or higher, or cooler outcomes. Nine of ten buckets resolve as NO for this contract.

Updated numerical weather prediction model runs tonight and tomorrow morning for Taipei are the key data events. A forecast shift toward 35°C or 37°C would push YES lower; a tight model consensus around 36°C would push it higher.

The market resolves at 12:00 UTC on July 25, 2026, based on the official recorded daily high temperature in Taipei from the designated weather data source.

Total volume is $64,304 with $159,080 in liquidity. The order book is healthy relative to activity, but the market is still modest in size. A single large trade could move the price noticeably before resolution.

What Could Shift These Probabilities?

Forecast Models Converge on Thirty-Six

If tonight's numerical weather prediction model runs cluster tightly around 36°C for Taipei on July 25, traders will push YES toward 45% to 50%. A morning of clear skies with light winds and strong solar heating would support a maximum right in the center of the typical late-July range. Urban heat island effects in central Taipei could lock in that outcome.

Heat Surge Pushes Past Thirty-Seven

A stronger-than-expected southwest monsoon surge on July 25 could drive Taipei's high to 38°C or 39°C, collapsing YES to near zero. July 2026 has seen multiple days across Taiwan's western plains exceeding 37°C. A repeat performance would leave the 36°C contract deep out of the money and hand a clean payout to broad NO holders.

Cloud Cover Cools the Afternoon

Afternoon convective development, which is common in Taipei during July, could cap the daily maximum at 34°C or 35°C even if the morning runs warm. This resolves NO but through the cooler end of the distribution. Traders holding positions on 35°C or 34°C buckets would benefit, while the 36°C YES contract closes worthless.

Typhoon Periphery Reshapes the Forecast

A tropical system approaching Taiwan's vicinity could dramatically alter wind flow and cloud cover with less than 24 hours of warning. Typhoon periphery effects have historically produced both anomalous heat surges and unexpected cooling in Taipei, depending on storm track. A late-breaking track shift would reprice every temperature bucket in this market simultaneously.

Key macro factor: Late July 2026 sits within an active southwest monsoon period for Taiwan, with sea surface temperatures in the western Pacific remaining elevated, supporting above-normal heat potential for Taipei through the end of the month.
