Who will have a top 20 song this year?

Settlement follows the timeframe defined in the market’s contract on the Kalshi page—check the market rules to see whether 'this year' means the calendar year (Jan 1–Dec 31) or another chart-reporting window; the official chart and date range in the contract determine settlement.

The specific chart used for settlement is listed in the market contract on Kalshi; common choices are national weekly charts (e.g., Billboard or equivalent), and the contract will name the chart and any particular chart week rules that apply.

Settlement follows how the chart itself credits the song: if the chart lists multiple credited artists or a 'feat.' credit, those credited names determine which outcome(s) are considered winners—consult the chart’s credited-artist conventions and the market’s settlement notes.

That depends on the market structure shown on Kalshi: if the market is a set of individual Yes/No contracts, multiple outcomes can win (each artist who achieves a top 20 entry); if the market is a single categorical contract, the contract’s rules will state whether it permits multiple winners or only a single winning outcome—check the market type and settlement rules.

A TBD close means the platform has not yet announced the final trading cutoff or settlement timing; trading remains subject to interim updates, and you should monitor the market page for the posted close date and any amendments to settlement mechanics before making decisions.
