Eleven discrete outcome buckets split the probability across a realistic temperature range, with 22°C claiming just 30.5% of the action. That’s not conviction. That’s a market pricing genuine meteorological uncertainty across a five-degree window. The contract asks a precise question: will Moscow’s highest temperature on July 4, 2026 land exactly at 22°C? The YES price sits at 0.31, the NO price at 0.70, and the market closes at noon Moscow time on July 4. Total volume is $3,016, all of it traded in the last 24 hours. How the Moscow Temperature Contract Works This market resolves on a single observed peak temperature. Only 22°C pays YES. Every other reading, from 17°C or below to 27°C or higher, pays NO. YES (22°C): pays if Moscow’s official highest temperature on July 4 equals exactly 22°C. Current price: 0.31, implied probability 30.5%.NO: pays if any other temperature is recorded. Current price: 0.70, implied probability 69.5%. The NO case is straightforward. Eleven possible outcomes compete here. Forecasts pointing to 21°C, 23°C, 24°C, or any reading outside 22°C all deliver the same NO payout. The threshold doesn’t require a dramatic miss. A single degree of deviation in either direction closes this market for NO holders. Sponsored Partner Momentum and Market Signals The momentum composite tells a cautious story. A 1-hour price drop of 4.0% alongside a trend score of 39.96 suggests sellers are active, not buyers. The most likely driver is incoming short-range forecast data showing conditions drifting away from the 22°C level. Volume deserves a hard look here. Total volume is $3,016, and all of it arrived in the last 24 hours. Liquidity sits at $26,907, which is unusually deep for this contract size. That mismatch means a small number of decisive trades could reprice this market sharply before resolution. Thin volume markets like this one move fast on new data. Key Factors The 1-hour price drop of 4.0% signals that short-range models are shifting away from 22°C as the most probable peak.Trader sentiment reads strongly bearish at 30.5% YES versus 69.5% NO, reflecting how fragmented the eleven-outcome structure makes any single bucket.Liquidity at $26,907 is disproportionately large relative to the $3,016 total volume, meaning the order book can absorb a directional trade without enormous slippage, but it also means the current price reflects thin conviction.No whale trades are on record for this contract, so no large-position signals exist to confirm the current directional lean. Lines Analysis: Moscow’s July Fourth Peak The current consensus from European and American short-range forecast models for Moscow on July 4 puts daily high temperatures in the low-to-mid twenties Celsius. July is Moscow’s warmest month, with climatological daily highs averaging near 24°C. A reading of 22°C sits slightly below that average, which is plausible but not the modal outcome when summer conditions hold. What makes NO real is the spread itself. Even if 22°C is the single most likely individual outcome, the combined probability of all other buckets overwhelms it. Forecasts showing 23°C or 24°C as the expected peak push probability mass into adjacent bins. A cooler-than-average airmass or a warmer one both deliver NO. The market doesn’t need confidence in a specific alternative. It just needs 22°C to miss. Signals to Monitor European Centre for Medium-Range Weather Forecasts updates for Moscow on July 3 will set the final pre-resolution anchor for temperature expectations.Any shift in the 850 hPa temperature field over western Russia in the next 48 hours would reprice adjacent buckets like 21°C and 23°C, directly affecting 22°C probability.Russian meteorological service Roshydromet publishes daily forecast updates that could confirm or contradict current model consensus before market close.Overnight low temperatures on July 3 into July 4 will signal whether a cooler or warmer air mass is in place, with implications for the daytime peak. Total volume of $3,016 is thin enough that this contract is pricing uncertainty rather than strong scientific consensus about a precise temperature reading. The data slightly favors NO, not because 22°C is impossible, but because ten other outcomes collectively own more of the probability space. The next 36 hours of forecast updates are the only thing that changes that math. LINES VERDICT Leaning NO, Structurally In an eleven-outcome market, any single bucket faces long odds. The current 22°C reading sits just below Moscow’s July climatological average, making it plausible but not the clear favorite among adjacent possibilities. What the market says: At 30.5% implied probability, the market treats 22°C as the most likely single outcome while still giving NO a commanding 69.5%. With resolution in less than 48 hours, any forecast shift will reprice this contract immediately. Key unknown: The July 3 evening forecast update from European models is the single data point most likely to move this contract before the noon July 4 close. A shift of even one degree in the expected peak would redirect probability mass to a neighboring bucket. Frequently Asked QuestionsWhat does 30.5% probability mean for the 22°C outcome?It means the market assigns roughly a one-in-three chance that Moscow's peak temperature on July 4 lands exactly at 22°C. Ten other outcome buckets hold the remaining probability.How does the NO contract pay out here?NO pays if Moscow's highest temperature on July 4 is anything other than 22°C. Any reading from 17°C or below to 27°C or higher, except 22°C exactly, resolves this contract for NO.What data would move this market's price before resolution?European and American short-range model updates for Moscow on July 3 are the primary drivers. A forecast shift toward 23°C or 21°C would pull probability out of the 22°C bucket immediately.When does this market resolve?The market closes and resolves at noon Moscow time on July 4, 2026, based on the officially observed peak temperature for that date.Is the volume and liquidity reliable here?Total volume is only $3,016, which is thin. Liquidity of $26,907 is comparatively deep, meaning a single large trade could shift the price sharply before resolution.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. It refreshes every hour. The percentage shows how many of those whales hold YES versus NO; the net dollar position shows the cohort's directional exposure in dollars.What is a convergence signal?A convergence event fires when three or more tracked wallets buy the same outcome on the same market within a four-hour window. We surface these in the activity feed and the VIP digest.Is Lines a market operator?No. Lines is an editorial and data product. We do not operate prediction markets, custody funds, or accept trades.

Models Converge on 22°C If the July 3 evening forecast update from European models locks onto a 22°C peak, probability mass flows into this bucket from adjacent outcomes. Thin liquidity means even a modest rush of YES trades pushes the price noticeably higher. A cool airmass arriving from the northwest would be the meteorological trigger. Forecasts Drift Warmer Moscow's July climatological average sits near 24°C. If short-range models show a warmer-than-current pattern developing, probability shifts to the 23°C or 24°C buckets. The 22°C YES price, already down 4.0% in the last hour, could slide further toward its 30-day low as the resolution window narrows. Cool Front Brings It Back An unexpected surface trough or cooler overnight low on July 3 into July 4 could cap the daytime peak closer to 22°C. Roshydromet forecast data confirming a suppressed high would pull probability back into this bucket from the 23°C and 24°C outcomes, giving YES holders a realistic path. Thunderstorm Breaks the Heat A mid-afternoon convective event over Moscow could abruptly suppress the daily maximum temperature. If a thunderstorm drops afternoon readings below the morning peak, the official high could land in an unexpected range. Weather markets close to resolution are uniquely exposed to this kind of hour-by-hour meteorological noise. Key macro factor: Moscow's summer temperature pattern in 2026 is influenced by the broader North Atlantic and Eurasian circulation regime, which in recent years has shown an increasing frequency of heat ridges over western Russia during July.
