Satellite radio ending subscribers measure the subscriber base at a specific reporting date. It is a period-end stock measure, not the number of subscribers served during the entire period.

SiriusXM ended 2025 with 32.927 million U.S. subscribers, down from 33.226 million at the end of 2024.

The total has two different subscriber populations

At December 31, 2025, SiriusXM reported:

31.345 million self-pay subscribers; and
1.582 million paid-promotional subscribers.

Those populations sum to the reported 32.927 million ending subscribers. The decomposition is more informative than the total alone because the payer and trial economics differ.

Sirius XM Canada is outside this subscriber count and outside SiriusXM's subscriber-based operating metrics.

Ending subscribers reconcile with the annual flow

The 33.226 million subscribers at the end of 2024 fell by 299,000 during 2025, producing the 32.927 million year-end balance. That is why net subscriber additions are a flow while ending subscribers are a stock.

The same distinction matters when interpreting revenue. A December 31 count does not represent the average base that generated twelve months of revenue.

Use the average base for period economics

For metrics such as ARPU, SiriusXM uses a daily weighted-average subscriber count rather than ending subscribers. Investors should therefore use the ending figure for point-in-time scale and the weighted-average figure for period-based monetization analysis.

Connects self-pay and promotional subscriber scale, churn and ARPU with automaker-driven installation and acquisition economics, then links those customer economics to subscriber and advertising revenue plus the direct content, royalty, service, and transmission cost stack.

Where this concept fits

Subscriber base, retention, and monetizationCurrent relationship
Self-pay and paid-promotional subscribers compose the ending subscriber base, while net additions show its change through the period. Weighted average subscribers support the ARPU denominator, churn captures self-pay retention, and ARPU shows recurring monetization after preserving the issuer's connected-vehicle exclusion.

OEM distribution, installation volume, and acquisition economics
Installation volume captures satellite-radio placements in new vehicles and aftermarket shipments. Subscriber acquisition costs fund that distribution footprint, SAC per installation scales those costs after the issuer's radio-margin adjustment, and equipment revenue adds the related hardware monetization stream.

Subscription revenue and direct service cost stack
Subscriber revenue is the core recurring revenue stream and advertising adds a smaller complementary source. Revenue-share and royalty, programming and content, customer service and billing, and transmission expenses show the major direct cost categories required to license, support, and deliver the service.
