SiriusXM

Dominant U.S. satellite and streaming audio company with one of the largest audio advertising platforms, combining owned inventory (SiriusXM, Pandora) with third-party ad tech (AdsWizz)

Sirius XM Holdings Inc. is a North American audio entertainment company headquartered in New York, New York, operating the SiriusXM satellite and streaming service, Pandora (the ad-supported and subscription streaming music platform), and a robust advertising business through its SiriusXM Media unit. The company reaches tens of millions of listeners across satellite radio, streaming, and connected devices, making it one of the largest audio media companies in the United States. SiriusXM's content portfolio spans music, sports, news, talk, comedy, and an extensive podcast library, distributed through in-car receivers, mobile apps, and smart speakers. On the advertising side, SiriusXM Media serves as the company's unified ad sales operation, offering brands access to its combined SiriusXM and Pandora audiences through audio, display, and podcast advertising. The company also owns AdsWizz, a leading programmatic audio advertising technology platform that powers dynamic ad insertion, programmatic buying and selling, and ad serving for podcasts and streaming audio across a broad network of publishers beyond SiriusXM's own properties. This makes SiriusXM a significant player in the audio ad tech ecosystem, providing both owned-and-operated inventory and third-party infrastructure for the broader streaming audio market. SiriusXM is publicly traded on NASDAQ under the ticker SIRI. The company generates revenue from two primary streams: subscriber fees from its SiriusXM and Pandora Premium services, and advertising revenue from Pandora's free ad-supported tier, podcast advertising, and third-party publisher monetization via AdsWizz. Its scale, first-party listener data, and integrated ad tech stack position it as a dominant force in audio advertising and a key partner for marketers seeking to reach engaged audio audiences.
