Resolution rules

Verbatim from the venue. The analyst must quote these, never paraphrase.

If the Consumer Price Index (CPI) increases by more than -0.4% (single-decimal) in September 2026, then the market resolves to Yes.

The market will always close at 8:25 AM ET on the scheduled day of the data release (October 14, 2026). Please note: the Expiration Value is the single-decimal value published at the Source Agency. In the case of a delay in data caused by a federal government shutdown impacting the reliability of the Source Agency, the market’s latest Expiration Date will be extended to the sooner of the release of the Underlying or six months after the end of the government shutdown.
