This market asks whether Houston's highest temperature on April 28, 2026 will fall between 74°F and 75°F—a notably narrow range of just one degree. The current 0% YES odds indicate traders believe this specific outcome is highly unlikely, suggesting the market expects Houston to experience either significantly warmer or cooler conditions that day. April is typically a transition month in Houston, with highs ranging from the low 70s to mid-80s depending on weather patterns. The 0% valuation reflects the inherent difficulty of predicting such a precise temperature band; even a few degrees above or below disqualifies the YES outcome entirely. This market is resolved based on official National Weather Service data for Houston, making it objectively verifiable at market close. The low odds may also reflect general trader skepticism about whether real-world temperatures will land in such a tight corridor, despite April's moderate seasonal conditions in Southeast Texas.
Deep dive — what moves this market
Houston's climate patterns in late April sit at the intersection of spring's lingering mild conditions and early summer's building heat. Historical data from the National Weather Service spanning decades shows that Houston's average high temperature in late April typically ranges between 80°F and 86°F, though daily variation is significant and highly dependent on synoptic-scale weather patterns, seasonal jet stream positioning, and moisture availability from the Gulf of Mexico. The 74–75°F range targeted by this market falls notably below Houston's typical April mean, which would require either a powerful cold front passage, persistent cloud cover from a slow-moving system, or unusual northerly wind flow from the continental interior. For the market to resolve YES, Houston would need to experience a notably cool day—cooler than the seasonal norm but not so cold as to be historically anomalous for the region. Several meteorological factors could theoretically push the market toward YES, though traders currently assign near-zero probability to them. A pronounced upper-level trough combined with a surface frontal system originating in the northern Great Plains could deliver cool air to the Gulf Coast. Persistent cloud cover from tropical or subtropical moisture advection would suppress maximum temperatures significantly by reducing solar insolation. Unusual amounts of precipitation from a stalled low-pressure system could also reduce surface heating and hold temperatures in the 74–75°F band. While these scenarios are meteorologically plausible in late April, they represent departures from the region's typical pattern and occur less frequently than average-to-above-average conditions. Conversely, the 0% YES odds largely reflect what meteorologists and traders collectively anticipate: a typical late-April pattern dominated by warm air advection from the south, clear-to-partly-cloudy skies, and strong solar insolation as the region transitions toward summer. Even a moderately cool day in Houston during this season often produces highs in the upper 70s or low 80s—just above the 74–75°F threshold. A high-pressure system settling over Texas, enhanced surface heating from low humidity, and persistent southerly flow from the Gulf of Mexico would all favor temperatures well above the target range. Temperature ranges this narrow over a 24-hour period in a subtropical city like Houston are statistically uncommon targets for prediction markets precisely because they require either fortunate alignment of multiple weather systems or atypical seasonal conditions. The 0% valuation reflects the statistical rarity of such a narrow outcome occurring and the market's collective assessment that broader temperature deviations are far more probable alternatives.

How does this market resolve?
Market resolves based on the official National Weather Service high temperature reading for Houston on April 28, 2026. YES wins if the reading falls between 74°F and 75°F inclusive; NO wins if the high is below 74°F or at 76°F or above.
