Sirius XM Holdings (SIRI) Monthly Active Users

Shows the number of unique users engaging with the platform each month, indicating user base size, platform popularity, and potential for subscription and ad revenue.

MAUs show a persistent multi-year decline with only brief stabilization and a modest late‑2026 uptick that still leaves reach well below 2020 levels.
