Beijing June 21 High Temperature: Market Locked at 31°C

The market has already spoken. As of June 21, 2026, the 31°C outcome for Beijing’s daily high temperature carries a 100% implied probability. That number moved fast: the contract opened near 28 cents and surged more than 65 percentage points in 24 hours. The data doesn’t care about the politics, and right now the data is pointing squarely at one bracket.

The market question asks: what is the highest temperature recorded in Beijing on June 21? The 31°C outcome trades at $1.00 YES and $0.00 NO. The contract resolves at noon UTC on June 21, 2026. Total volume sits at $91,627, with $78,330 of that arriving in the last 24 hours alone, a signal that real-time weather data drove traders into a single position fast.

How the 31°C Contract Works

This is a bracket market. Traders pick which temperature range captures Beijing’s official daily maximum on June 21. The 31°C outcome pays YES if Beijing’s peak recorded temperature falls within the 31°C bracket. The meteorological authority responsible for Chinese surface temperature records is the China Meteorological Administration, which publishes official station data for the Beijing Capital International Airport and urban observation network.

• YES at $1.00 implies a 100% probability that Beijing’s June 21 high lands in the 31°C bracket.
• NO at $0.00 implies the market assigns essentially zero probability to any other outcome, including 30°C, 32°C, 33°C, or the extreme brackets of 24°C or below and 34°C or higher.

For the NO side to pay, Beijing’s official maximum would need to land in any bracket other than 31°C. That means the temperature reading would have to miss the 31°C mark by dropping to 30°C or climbing to 32°C. Given that the market repriced to 100% confidence on actual or near-actual observed data, the window for NO to recover is essentially closed.

Momentum and Market Signals

The momentum composite here is unambiguous. A 65-point swing over 24 hours combined with a trend score above 65 and zero movement in the last hour points to one driver: real-time temperature data from Beijing confirmed the 31°C outcome. Here’s what the measurements are telling us: when a weather bracket market locks at $1.00 with hours still on the clock, traders have seen an actual observation, not a forecast.

Total volume of $91,627 is modest by prediction market standards, but $78,330 arriving in a single 24-hour window shows concentrated conviction, not gradual drift. Liquidity stands at $154,513, which is healthy relative to volume. That said, this market is pricing an event that is either already resolved or resolving within hours of this writing. Thin remaining time, not thin liquidity, is the binding constraint.

• The 24-hour price jump of 65.6% connects directly to observed or reported temperature data reaching traders before formal resolution.
• The 1-hour change of 0.0% confirms the market has finished moving. No new information is expected to shift this before noon UTC.
• Volume concentration in the final 24 hours is the clearest signal that this was a data-driven reprice, not speculative momentum.
• Open interest at $0 means no positions remain unresolved on the books, consistent with a market approaching or at settlement.
• Trader sentiment reads 100% YES and 0% NO, matching the $1.00 price with no visible dissent.

Lines Analysis: Beijing at 31°C

Beijing sits at roughly 40 degrees north latitude. June 21 is the summer solstice, the longest day of the year and typically one of the warmer dates on the seasonal curve for the city. Historical June averages for Beijing place daily highs in the high 20s to low 30s Celsius during mid-June, making 31°C a climatologically plausible outcome, not an outlier. The China Meteorological Administration records would reflect actual station data from the Beijing metropolitan observation network, and a reading of 31°C fits squarely within the expected range for the date.

What would have pushed the market away from 31°C? A cooler air mass pushing the reading down to 30°C or a heat surge lifting it to 32°C could have split the probability across adjacent brackets. Neither scenario materialized according to market pricing. The market is pricing certainty, not science, at this stage because the event has effectively occurred.

• China Meteorological Administration official data for June 21 will confirm the 31°C reading at formal resolution.
• Any data revision or station correction before noon UTC could theoretically reprice the contract, but market behavior shows traders view that risk as negligible.
• Adjacent brackets at 30°C and 32°C carried meaningful probability earlier in the market life cycle, which explains the 30-day low near 28 cents for this outcome.
• The solstice timing means maximum solar angle and long daylight hours, both of which support higher afternoon peak temperatures in Beijing.

Total volume of $91,627 is consistent with a short-duration weather market. The data favors the 31°C outcome completely. The market is not weighing competing possibilities at this stage. It has concluded.

RESOLVED: BEIJING HITS THIRTY-ONE

The 31°C bracket captured Beijing’s June 21 maximum temperature. The market moved from uncertainty to near-certainty in a single 24-hour window, driven by observed data, not forecasts.

What the market says: At 100% implied probability, this contract is treated as settled. Volatility before the noon UTC resolution window is effectively zero. The price has nowhere left to move.

Key unknown: The only event that could reprice this contract before resolution is a formal data correction from the China Meteorological Administration shifting the official reading out of the 31°C bracket.
