Event Rules

This market will resolve according to the number of albums that are ranked number 1 on any official weekly Billboard 200 albums chart released for a data collection reference period entirely between January 1 and December 31, 2026. Each specific album may only count once, regardless of the number times it reaches the number 1 spot. Different editions of the same album will be considered to be different specific albums if they contain different tracklists. 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 titled “Week of (date of the upcoming Saturday)”. The first Billboard 200 album chart relevant to this market will be the chart titled “Week of January 17, 2026” for a data collection reference period of January 2-8, 2026. The final Billboard 200 album chart relevant to this market will be the Chart titled “Week of January 9, 2027” for a data collection reference period of December 25-31, 2026. All officially published Billboard 200 Albums charts will be treated as final. Revisions made after the release of a Billboard 200 album chart will not be considered. The primary resolution source for this market will be the official weekly Billboard 200 albums chart, published each week at https://www.billboard.com/charts/billboard-200/ and through other official Billboard channels; however, a consensus of credible reporting on albums that reached number 1 on the Billboard 200 within this market's timeframe may also be used.
