What will Zyn's point-of-sale growth be in September?

Kalshi

All markets resolve based on the Carbon Arc Zyn Point of Sale Growth index for September 2026, with each market requiring the index to exceed a specific threshold (ranging from 93 to 103). The index measures year-over-year change, where 100 indicates equal spending compared to the prior year, with values above 100 signifying growth and below 100 indicating decline. Determination for all markets relies on the first value reported by Carbon Arc, and any subsequent corrections or revisions after settlement will not affect the outcome. The index is calculated using data from in-store and online purchases captured via receipt-scanning and rewards apps, matched to the same period of the prior year, and updates daily as new data becomes available.
