Will "Dandelion - Ella Langley" be the Billboard 200 #1 album for the week of September 19?

Kalshi — primary rule

If DANDELION is #1 on the Billboard 200 chart for the Week of Sep 19, 2026, then the market resolves to Yes.

Polymarket — resolution criteria

Billboard updates the Billboard 200 albums chart each Tuesday (with adjusted release schedules on some holiday weeks), reflecting data from the previous week (Friday-Thursday). Each Billboard chart is then dated “Week of (date of the upcoming Saturday)”. This market will resolve according to the number 1 album on the Billboard 200 chart dated “Week of September 19, 2026”. Albums will be primarily ranked by order on the specified chart. If two or more albums are tied for any position, ties will be broken by alphabetical order of the albums' listed titles. This market will resolve to the album that occupies the highest finishing position after applying this ranking. This market will resolve as soon as the relevant chart is published. If the Billboard 200 chart for the specified week is not published within 14 calendar days of the expected release date, this market will resolve to “Other”. The resolution source for this market will be the Billboard 200 chart for the specified week, published on the Billboard website (https://www.billboard.com/charts/billboard-200/) or through other official Billboard channels.
