The contract resolves on April 8. The market currently prices 24C at 35 percent, meaning traders see this as a coin-flip outcome tilting toward something else landing. That something else spans a wide field of alternatives from 22C to 28C or above, and no single rival outcome commands enough conviction to dominate the board. The market prices the 24C outcome at 0.35 (YES) against 0.65 (NO). Total volume stands at $71,635, with $44,389 changing hands in the last 24 hours. Liquidity sits at $17,086, which is thin enough that one sharp weather data drop could move this price fast. How the Paris April 8 Temperature Contract Works This contract resolves YES if the highest temperature recorded in Paris on April 8, 2026 lands exactly at 24 degrees Celsius. Resolution is determined by the market’s designated weather measurement source for that calendar day. Every other possible peak temperature resolves this contract NO. YES (24C): Priced at 0.35, implying a 35 percent probability that April 8 peaks at exactly 24C in Paris.NO (all other outcomes): Priced at 0.65, covering 25C, 23C, 26C, 22C, 27C, 21C, 20C, 28C or higher, 19C, and 18C or below. A NO resolution does not require a cold day. It requires any temperature other than exactly 24C. Paris in early April averages daily highs near 15 to 17C, but warm spells regularly push readings into the low to mid 20s. The spread across outcomes is wide. If forecasters show 23C or 25C with equal confidence, a 1-degree miss in either direction routes capital to NO regardless of how warm the day actually feels. Momentum and Market Signals Are Pointing Cautiously Higher Sponsored Partner The 24-hour price change of plus 0.5 percent is a modest positive signal. Combined with the price history context, this reflects a market that has repriced upward as short-range weather models began converging on warmer conditions for early April in the Paris basin. The move is not large enough to suggest conviction. It reads as model alignment, not certainty. Volume tells a clearer story. $44,389 traded in 24 hours against a total market of $71,635 signals that more than 60 percent of all money in this contract moved today. That pace suggests active repositioning as the resolution date closed in. Liquidity at $17,086 is below the threshold where price is stable under large orders. New forecasts or a single large bet could shift the price materially before April 8 closes. The 24h price change of plus 0.5 percent, combined with recent volume activity, points to modest upward momentum tied to short-range model convergence toward warmer April 8 conditions in Paris.$71,635 in total volume reflects a small but actively traded market. Thin liquidity at $17,086 means a single large position could move the price sharply on any forecast revision.Trader sentiment leans bearish at 65 percent NO, suggesting the majority of capital does not expect the peak to land exactly on 24C even if April 8 is warm.The 30-day price range has been wide, from 0.20 to 0.51, confirming that forecast uncertainty has been the dominant driver of repricing throughout this contract’s life.Related market context: the 55 percent probability on 2026 ranking among the hottest years on record reinforces that broad warming conditions are in play. That doesn’t guarantee 24C in Paris on one day, but it rules out anomalous cold. Lines Analysis: Meteo France Forecasts and the Degree That Matters April 8 sits in a stretch of early spring in Paris where daily highs swing sharply based on Atlantic frontal systems. AccuWeather’s monthly forecast for April 2026 shows Paris daily highs ranging from 58F to 77F, which translates to roughly 14C to 25C. The upper end of that range touches exactly the 24C to 25C zone where this contract lives. That matters. A warm, settled pattern on April 8 makes 24C plausible. A passing front or cloud cover holds the peak closer to 18C to 21C. The broader field of NO outcomes is the real risk here. A forecast showing 25C or 26C would still resolve this contract NO. A cool front keeping Paris at 22C also resolves NO. The 24C outcome requires the temperature to peak at exactly one number. Weather forecast precision at the one-degree level, at 72-hour range, is imperfect by definition. That structural imprecision is what the 65 percent NO pricing captures. It is not a bet against warmth. It is a bet against pinpoint accuracy. Meteo France 48 to 72 hour forecasts for the Paris basin will be the single most important price driver before resolution. Any shift to 23C or 25C as the modeled peak reprices this contract sharply.Atlantic frontal timing is the key wildcard. A warm ridge holding through April 8 keeps 24C in play. A cold trough arriving a day early ends the conversation.European Centre for Medium-Range Weather Forecasts ensemble data, if it tightens around 24C for April 8, would be the clearest bullish signal for this outcome.The 2026 broader warming context supports a warmer-than-average April in Paris, but one-day peak precision at a single degree threshold remains the core uncertainty. $71,635 in total volume places this in the small but fast-moving category. The data favors a warmer April 8 in Paris relative to historical averages. It does not favor exactly 24C over 23C or 25C. That gap between directional warmth and pinpoint temperature precision is where the market is pricing its uncertainty. LINES VERDICT Uncertainty Holds: Warm Day Likely, Exact Peak Unknown The data supports a warm April 8 in Paris. It does not support confident pricing of exactly 24C over the field of nearby alternatives that each carry real probability. What the market says: 35 percent implies traders see 24C as a real contender but not the probable winner. With resolution just hours away and liquidity thin at $17,086, any forecast update carries outsized price impact. Key unknown: The Meteo France 24-hour point forecast for Paris on April 8 is the single data point that will reprice this contract. If that model settles on exactly 24C as the day’s peak, YES probability moves sharply higher. If it shows 23C or 25C, the NO position firms up immediately. Scientific Context: April Temperature Variability in Paris Paris in early April sits in a meteorologically volatile window. The city averages a daily high near 15 to 17C in the first week of April, based on long-term climate records. But interannual variability is high. Warm spells tied to southerly flow or high-pressure blocking can push peaks well into the low to mid 20s for multiple consecutive days. The broader warming trend in European spring temperatures, consistent with global 2026 heat rankings currently priced at 55 percent on related markets, supports above-average readings being more likely than average ones. That context makes 24C a physically reasonable outcome for April 8. It does not make it more probable than the combined weight of all the alternatives sitting inside the NO position. Frequently Asked Questions What does 35 percent mean for this market? It means traders estimate a roughly one-in-three chance that Paris peaks exactly at 24C on April 8. Two-in-three traders expect the peak to land at a different temperature.What pays out on NO? Any Paris high temperature on April 8 other than exactly 24C resolves this contract NO. That includes warmer outcomes like 25C or 26C and cooler outcomes like 22C or 23C.What data event would move this price most? A Meteo France or European weather model forecast pinning April 8’s Paris high at 24C would push YES sharply higher. A forecast showing 23C or 25C would firm up NO pricing immediately.When does this contract resolve? Resolution is tied to April 8, 2026. The market closes once the official high temperature for Paris on that date is confirmed by the resolution source.Is trading volume here reliable for price signals? $71,635 in total volume and $17,086 in liquidity places this in the low-volume category. Price can move sharply on modest new orders. Treat the current 0.35 price as a live estimate, not a stable consensus. This analysis reflects market conditions as of April 7, 2026. Prediction market probabilities are volatile and shift as new data and weather forecasts emerge, especially as the April 8 resolution date approaches.

Market Resolved Outcome: YES Final Price 100% Settled Apr 8, 2026 Duration 4 days Resolution Analysis Model Convergence on 24C If the European Centre for Medium-Range Weather Forecasts ensemble and Meteo France both pin April 8's Paris peak at exactly 24C in their final short-range output, YES probability climbs sharply from 35 percent. Thin liquidity amplifies the move. Warm southerly flow without cloud cover is the setup that keeps 25C from stealing this outcome. Adjacent Temperature Steals the Day Paris peaks at 23C or 25C. Both outcomes are meteorologically plausible and both resolve this contract NO. The one-degree precision required for YES is the structural drag on this outcome. Even a warm, pleasant April 8 routes all payout to NO if the thermometer stops one tick short or runs one tick long. Late Forecast Revision Lifts 24C Short-range weather models update multiple times in the 24 hours before resolution. A late revision away from 23C or 25C toward 24C as the modeled peak would reprice YES upward quickly. With volume running hot and liquidity thin, a single credible forecast shift could move this market several percentage points in hours. Unexpected Frontal Timing An Atlantic cold front arriving earlier or later than models predict scrambles the entire temperature field. Early arrival keeps Paris well below 24C. Late arrival lets afternoon heating push past 25C. Either scenario benefits NO broadly, but the path matters for which specific temperature outcome captures the payout. Key macro factor: The 2026 European spring warming pattern, consistent with global temperature rankings currently priced at 55 percent on related Polymarket contracts, supports above-average April temperatures in Paris but does not resolve one-degree forecast precision at the daily peak level.
