Spotify's audience-based ad network reaching listeners across Spotify and third-party apps.
Megaphone hosted shows
SPAN dynamically inserts ads into Megaphone-hosted shows. Big demand pool, modest publisher control. The 2026 shift is bigger than the 2025 floor change — Spotify is transitioning Megaphone publishers to Spotify's full ad stack midyear, opening direct-sold and PMP deal trafficking through the same platform.
Spotify Audience Network is the demand-side companion to Megaphone — a programmatic ad network that places audience-targeted ads into podcasts hosted on Megaphone, with reach extending beyond Spotify into third-party podcast apps. The mechanic is simple: Megaphone-hosted shows opt into SPAN, Spotify's ad sales team runs campaigns against the inventory, revenue splits. Megaphone publishers opted into SPAN have seen fill rates increase over 10 percent and CPMs over 40 percent on covered inventory. The 2026 development that matters more than 2025's price-floor changes: beginning midyear 2026, Spotify will transition Megaphone-hosted publishers to Spotify's broader ad stack, enabling publishers to traffic both direct-sold campaigns and private marketplace (PMP) deals through Spotify's ad technology. That broadens what Megaphone can be — not just a SPAN demand channel but a full sales-ops platform with access to video ads and clickable audio formats. The catch is still that you must be on Megaphone to participate, and Megaphone is an enterprise hosting platform with bandwidth-based pricing aimed at networks rather than indies. The 2025 removal of publisher-set price floors also means Spotify's sales team effectively controls the auction rate card. Where it shines is in giving Megaphone customers meaningful programmatic monetization with no operational lift. Where it falls short is creator agency. For control and direct relationships, Acast or Libsyn Ads give you more autonomy at the cost of less demand.
