Each unique song title counts only once regardless of weeks on chart or re-entries. Different versions with distinct titles (acoustic, remix) count separately. Songs from before issuance that re-enter during the contract period count toward the total. Collaborations where the artist shares equal billing or is featured count. Songs count only if the artist is credited as primary or featured performer, not as producer/songwriter. Only positions within the chart's standard range qualify (e.g., 1-100 for Hot 100, not "bubbling under"). This market and these products have not been endorsed by Billboard. Any references to "Billboard", the "Hot 100," or any other associated marks are descriptive only, and do not indicate an endorsement of this product or any affiliation between Billboard and Kalshi.
