Moscow June 27 High Temperature: Will It Hit 21°C?

The market resolved this question before noon Moscow time. A single-day temperature contract for Moscow on June 27 is sitting at 96.9% implied probability for the 21°C outcome. That is not a debate anymore. The market has concluded the answer, and the momentum behind it is almost vertical.

The market question asks whether the highest temperature in Moscow on June 27 reaches 21°C. The YES price sits at $0.97, the NO price at $0.03, and the contract resolves at 12:00 UTC on June 27, 2026. Total volume is $34,369, with $22,040 of that trading in the last 24 hours alone.

How the 21°C Moscow Temperature Contract Works

A YES resolution means Moscow’s official daily high temperature on June 27 records exactly 21°C. The NO side covers every other outcome: any of the listed alternatives from 17°C or below up through 27°C or higher. The responsible measurement body determines resolution based on the official Moscow temperature reading for the date.

• YES (21°C): $0.97 per share, implying a 96.9% probability that Moscow’s June 27 high lands at exactly 21°C.
• NO (any other outcome): $0.03 per share, implying a 3.1% probability that the high temperature differs from 21°C.

The NO side requires the official daily maximum to land on any other listed threshold: 17°C or below, 18°C, 19°C, 20°C, 22°C, 23°C, 24°C, 25°C, 26°C, or 27°C or higher. With resolution just hours away and real-time weather data feeding into trader decisions, the window for a temperature surprise to move this contract is essentially closed.

Momentum and Market Signals

The momentum composite here is extraordinary. A 50.9% one-hour price jump combined with a 58.4% gain over 24 hours and a trend score of 69.23 points to one driver: real-time temperature data confirming Moscow’s June 27 readings are tracking directly toward 21°C. Traders are not speculating anymore. They are locking in a near-certain outcome as observational data arrives.

Total volume of $34,369 is modest for a prediction market, and the $22,040 in 24-hour volume tells the real story. Most of the trading happened today, as weather data clarified the outcome. Liquidity stands at $61,275, which is deep relative to total volume. That depth means the 96.9% price is stable and not easily moved by a single large order. Volume below $1 million means any unexpected late data could still produce a sharp price move, but the window is narrow given the resolution time.

• The one-hour and 24-hour momentum signals are moving in the same direction, driven by real-time Moscow temperature observations confirming the 21°C threshold.
• Liquidity at $61,275 outpaces total volume, indicating the order book is well-supported and the current price reflects strong consensus.
• Trader sentiment reads 96.9% YES versus 3.1% NO, which is among the most lopsided readings a single-day weather contract can show this close to resolution.
• The market’s 30-day low of $0.26 shows how uncertain this outcome looked at the start of the contract period, before current-day weather data arrived.
• The 58.4% 24-hour price gain reflects the moment traders received confirmation, not speculation about future weather.

Lines Analysis: What the Moscow Weather Data Says

Moscow’s meteorological station data drives this contract. The near-vertical price move in the last 24 hours signals that real-time temperature readings, likely from the Moscow observatory or equivalent official source, are tracking to 21°C as the day’s high. Traders with access to current weather feeds have moved the price to near-certainty. The data doesn’t care about the politics, and it does not care about adjacent prediction markets either.

The only meaningful path for the NO outcome requires the official daily maximum to settle at a different threshold by resolution. A late-afternoon temperature spike above 21°C, a recording instrument discrepancy, or an unusual weather shift could theoretically reprice this contract. June in Moscow carries some volatility risk: the city’s continental climate can produce rapid temperature changes. But with the contract resolving at 12:00 UTC, the measurement window is effectively closed or closing. The market has already absorbed that information.

• Any official revision to the Moscow daily maximum temperature before the 12:00 UTC resolution would immediately reprice the contract.
• A final official reading above 22°C or below 20°C would transfer value entirely to the NO side.
• Instrument discrepancies at the official Moscow weather station represent a tail risk the market is pricing at roughly 3%.
• Related markets show no correlated signal: the linked contracts (hantavirus, moon landing, IPO rankings) have no causal connection to Moscow’s June 27 temperature.

Here is what the measurements are telling us: the market treated this as highly uncertain as recently as June 25 (a 6% price drop that day shows the contract was repricing), and then confirming data arrived and traders moved aggressively. The $22,040 in 24-hour volume reflects conviction, not noise. The data favors YES overwhelmingly, but the low total volume means anyone watching for late official data should stay alert until 12:00 UTC.

LINES VERDICT

NEAR-CERTAIN YES

The real-time temperature data flowing into this market has done the work. Moscow’s June 27 high is tracking to 21°C, and traders have priced that confirmation at near-maximum probability with hours left before resolution.

What the market says: At 96.9% implied probability, the market has effectively called this outcome. The only volatility risk before the June 27, 2026, 12:00 UTC resolution is an official measurement revision or an unusual late-day weather shift that changes the recorded maximum.

Key unknown: The single most important remaining variable is the final official temperature reading from the Moscow meteorological authority before the 12:00 UTC resolution cutoff. Any deviation from 21°C in that official record reprices this contract sharply.
