Market Rulebook: Who will win American Idol?

Official settlement criteria, resolution sources, and edge cases across Kalshi.

KalshiKalshi
Primary Rule

If Brooks Rosser is officially declared the winner of American Idol Season 24 (ABC Season 9), then the market resolves to Yes.

Edge Cases

This contract refers to American Idol Season 24 overall, which is Season 9 of the ABC revival. The season premiered in 2026 and airs on ABC. For the avoidance of doubt, Season 24 reflects the total number of seasons since the series originally debuted in 2002 (including Seasons 1–15 on Fox Broadcasting Company and Seasons 16–24 on ABC). The winner must be officially announced in the finale or via official channels immediately following. Multiple joint winners each resolve to Yes with split payouts ($1 divided by number of winners). If no winner is declared, all markets resolve to No. Winners who decline the award still count unless acceptance was a condition of victory. Disqualifications or withdrawals before the finale resolve to No. Later title stripping doesn't affect resolution - the original finale announcement governs. Fan favorite or other secondary awards don't count as winning. For couples/teams competitions, being part of the winning unit counts.
