Will the maximum temperature be 88-89° on Oct 21, 2026?

How this settles

Each contract in this series resolves YES if the maximum daily temperature recorded at Phoenix station CLIPHX, per The Weather Company, falls within the specific range, above the threshold, or below the threshold defined for that contract's settlement date.

• Inclusive vs. strict bounds differ by variant — Variant 1 uses an inclusive range (between the two threshold values), while Variants 2 and 3 use strict greater-than/less-than comparisons — hitting an exact boundary value resolves YES in Variant 1 but NO in Variants 2 and 3.
• Single source: The Weather Company only — CLIPHX data from NWS, Weather Underground, or any other provider is irrelevant — only The Weather Company's reading governs resolution, even if other sources disagree.
• Station is CLIPHX, not a generic Phoenix airport reading — The Climate (CLI) station code CLIPHX may differ from nearby ASOS or METAR stations; traders should confirm The Weather Company's CLIPHX print, not a general Phoenix-area high.
• No revision policy stated — The rules do not specify whether an initial or revised/corrected temperature print from The Weather Company is used, so a late data correction could affect resolution unexpectedly.

These are the rules for the whole series — every contract in it settles the same way. Full KXHIGHTPHX settlement rules →
