Who will have a #1 hit this year?

Resolution follows the contract's official terms on KALSHI. The market description will specify which chart(s) are used and the date range (for example a calendar year or a defined week range). If that information is not on the public page, consult the contract text or KALSHI support for the authoritative resolution criteria.

The market remains open until KALSHI posts a close date and the contract's resolution schedule; KALSHI will announce or update the close/resolution date on the market page. Watch the market page and official announcements for timing.

Charts typically credit the artists as they appear on the official chart entry; the contract will specify whether any credited artist on a #1 counts as a winner. For joint credits and remixes, rely on the chart's credited artist listing and the contract's rules for resolution.

Most markets of this form pay the outcome(s) that meet the contract's resolution criteria. That usually means a single winning outcome unless the contract explicitly allows multiple winners (for example, if multiple credited artists on the same #1 are each listed outcomes). Check the payout rules in the contract text.

Track official single release dates, major playlist adds, streaming and digital sales reports, weekly chart updates, radio add reports, music video drops, award-show performances, and viral trends or challenges on social platforms—these events commonly drive sudden shifts in market expectations.
