Houston’s highest temperature on May 26 hitting 82°F or above carries a 99% implied probability, and the data behind that number is about as clean as weather forecasting gets. Late May in Houston is deep into warm season territory. The atmosphere doesn’t negotiate. The market question asks whether Houston’s daily high will reach 82°F or above on May 26, 2026. The YES price sits at 0.99 and the NO price at 0.01, with resolution set for 2026-05-26 at noon. Total volume stands at $23,993 across this contract’s life. How the Houston Temperature Contract Works YES pays out if Houston’s official high temperature on May 26 reaches 82°F or above. NO covers a fragmented field of lower ranges: 80-81°F, 78-79°F, 76-77°F, 74-75°F, 72-73°F, 70-71°F, 68-69°F, 66-67°F, 64-65°F, and 63°F or below. The resolution source is market resolution tied to official temperature observation. YES (82°F or higher): priced at $0.99, implying a 99% probability of the Houston daily high reaching that threshold.NO (any range below 82°F): priced at $0.01, meaning the market assigns a 1% combined chance across all cooler outcomes. A NO payout requires Houston’s high to stall below 82°F. That means an unusually strong cold front, persistent cloud cover, or a late-season anomaly that keeps temperatures in the upper 70s or lower. Houston’s late May climatology makes that scenario rare. The National Weather Service’s Houston/Galveston office tracks this, and historical averages for late May put daily highs comfortably in the mid-to-upper 80s. A failure to hit 82°F would be a genuine outlier. Sponsored Partner Momentum and Market Signals The trend score registers at 67.26, which reflects sustained directional conviction rather than late-breaking movement. With the contract expiring today at noon, there is no meaningful price change in the last hour or 24 hours because the price has been pinned near ceiling for some time. The driver here is not a data release or regulatory announcement. It is meteorological reality: late May Houston temperatures at or above 82°F are the rule, not the exception. Total volume on this contract is $23,993, with $2,313 traded in the last 24 hours. Liquidity reads at $126,754, which is unusually deep relative to total volume. That asymmetry suggests the order book is well-supplied but trading activity is low because there is little price discovery left to do. At sub-$25K total volume, sharp price movement on new information is theoretically possible, but with resolution hours away, the practical window for repricing has closed. The 1h and 24h price changes are flat, consistent with a market that resolved its uncertainty days ago and is simply waiting for the clock to run out.Trader sentiment is strongly bullish at 99% YES and 1% NO, with no whale trades on record to suggest institutional disagreement.Liquidity at $126,754 is high relative to volume, meaning the order book can absorb a large bet without moving the price materially.The trend score of 67.26 reflects steady, not accelerating, conviction. The market is not panicking in either direction.Resolution at noon local time means any surprise weather development this morning is the only remaining variable. Lines Analysis: What the Houston Data Is Telling Us Late May climatology for Houston is the primary signal here. The city sits in a subtropical humid climate zone, and by the final week of May, the Gulf of Mexico moisture and solar angle combine to push daily highs reliably into the mid-to-upper 80s under typical conditions. A high of 82°F would actually be on the cooler end of the late-May range. The market is not pricing optimism. It is pricing a baseline that decades of temperature records support. The one scenario where NO becomes relevant is a synoptic weather pattern that drags cooler air into the region: a strong low-pressure system, an unusually persistent marine layer, or a fast-moving front arriving before the afternoon peak. None of those conditions appear to be in play based on current National Weather Service forecast data for Houston on May 26. That’s what the 99% is really saying. The data doesn’t care about the politics, and the atmosphere doesn’t care about the market. It just does what it does. National Weather Service Houston/Galveston forecast data for May 26 will be the definitive real-world signal before noon resolution.Any morning temperature reading well below 80°F would be an early warning that a cooler-than-expected pattern is developing, though such a scenario appears highly unlikely.The Gulf moisture regime in late May typically prevents the type of dry, cool air intrusion that would hold Houston below 82°F.A strong mesoscale convective system or unusual cloud persistence could theoretically cap the afternoon high, but the probability is priced at 1%.Post-resolution confirmation from official observation will close this contract with essentially no suspense. The $23,993 in total volume reflects a small but clearly directional market. Both the meteorological baseline and the current pricing point the same way. The data favors YES, and the market has reflected that for the full life of this contract. LINES VERDICT NEAR-CERTAIN YES Houston’s late May climatology and current forecast conditions make a daily high below 82°F a genuine outlier. The market has already concluded this, and the data agrees. What the market says: At 99% implied probability, the market treats this outcome as settled. With resolution at noon today, the window for any repricing is essentially closed. Thin total volume means a surprise weather event could theoretically move price, but the meteorological setup makes that highly unlikely. Key unknown: The single variable that could reprice this contract is an unexpected morning weather development, specifically a fast-moving front or persistent cloud cover that holds Houston’s afternoon high below 82°F before the noon resolution deadline. Scientific Context Houston’s climate record shows late May daily highs averaging in the mid-to-upper 80s Fahrenheit, with readings below 82°F occurring in fewer than roughly 10-15% of late May days historically. The 82°F threshold in this market sits below the typical late May average, making YES the climatologically favored outcome by a wide margin. The market pricing at 99% is consistent with, and arguably supported by, that historical baseline. The gap between the threshold and the expected high is what makes this contract so one-sided. How likely is 99% for a daily temperature market? A 99% implied probability means traders collectively estimate a 1% chance of Houston staying below 82°F on May 26. Given late May climatology, that reflects real-world meteorological odds closely. What pays out on the NO side? Any of the alternative outcomes, ranging from 80-81°F down to 63°F or below, pay if Houston’s official daily high falls short of 82°F. The combined probability across all those ranges is currently 1%. What single event would move this price before resolution? An unexpected strong frontal passage arriving in Houston before the afternoon temperature peak on May 26 is the one meteorological event that could push the price off 99%. National Weather Service forecast updates this morning are the key data source. When does this market resolve? Resolution is set for 2026-05-26 at 12:00 noon. The contract expires today, meaning the outcome will be confirmed within hours of this writing. How reliable is the volume and liquidity data here? Total volume is $23,993, which is below the $1 million threshold for high-confidence signals. However, liquidity at $126,754 is deep relative to volume. The price could move sharply on a surprise, but the meteorological basis for the current price is strong regardless of volume size. This analysis reflects market conditions as of 2026-05-26 01:10:27. Prediction market probabilities are volatile and shift as new data and regulatory decisions emerge, especially as the 2026-05-26 12:00:00 resolution date approaches.

Market Resolved Outcome: YES Final Price 100% Settled May 26, 2026 Duration Same day Resolution Analysis Typical Late May Pattern Holds Houston's subtropical climate delivers its standard late May afternoon heat, pushing the official high into the mid-to-upper 80s°F. The 82°F threshold is cleared before noon. The National Weather Service Houston/Galveston office confirms the reading, and the YES contract pays out at 99 cents on the dollar. Morning Cloud Cover Delays Peak Heat Persistent morning clouds or elevated Gulf moisture reduce solar heating and slow the temperature rise. Houston's high stalls in the upper 70s or just above 80°F. This outcome is priced at 1% for a reason: it requires an unusual combination of atmospheric conditions rarely seen in late May. NO Range Closes In Near Deadline A fast-moving frontal boundary arrives earlier than forecast models predicted, pulling cooler continental air into the Houston metro before the afternoon temperature peak. The official high lands at 80 or 81°F, pushing the 80-81°F NO range into the money. The National Weather Service morning update before noon would be the key warning signal. Mesoscale Convective System Caps the High An overnight or early morning thunderstorm complex moves through Houston, leaving behind cooler, cloud-covered conditions that prevent the typical afternoon heating. If cloud cover and rain-cooled air persist past 10 a.m., the daily maximum could stall well below 82°F. This scenario is rare in late May but not climatologically impossible. Key macro factor: Houston's position in the Gulf Coast subtropical regime means late May daily highs are consistently elevated, driven by Gulf moisture and strong solar angle, making sub-82°F outcomes historically uncommon.
