Houston's weather on April 18, 2026 is the subject of this focused prediction market. The question asks whether the highest temperature recorded in Houston will fall precisely between 66 and 67 degrees Fahrenheit—a narrow, specific band. This is a fully resolvable, objective event that will be measured against official Houston temperature data. The current 0% YES odds reveal strong market consensus: traders do not expect Houston to record a high in this exact range on April 18. At this price, the market is saying the temperature will deviate significantly from 66-67°F—either staying cooler below 66°F or warming above 67°F. For context, Houston's typical April highs run in the low-to-mid 80s Fahrenheit, making this narrow 66-67°F band well below seasonal average. The market will resolve using the official highest temperature from Houston's primary National Weather Service station on April 18. Resolution is completely transparent, measurable, and auditable against publicly available weather records. Current 24-hour trading volume of $573 reflects limited market activity in this specific temperature band, consistent with the extreme tail-probability odds.
