IAS and Spotify launch episode-level pre-bid podcast ad optimization via The Trade Desk

This launch provides the granular control necessary to unlock higher-tier brand budgets for programmatic podcasting. By moving suitability checks to the pre-bid stage at the episode level, Spotify and IAS are bringing audio buying parity closer to digital display and video standards. As U.S. podcast ad revenue reached $2.9 billion in 2025 according to IAB data, this infrastructure shift allows major agencies to scale spend without the reputational risks inherent in broad-reach audio buys. Watch for this integration to expand from The Trade Desk to other DSPs like Google DV360 and Amazon DSP in the second half of 2026.

The rollout follows a period of rapid infrastructure expansion for Spotify’s advertising business. In April 2025, per PPC Land, Spotify launched the Spotify Ad Exchange (SAX) to modernize its automated offerings through real-time auctions. This move was supported by partnerships with major demand-side platforms including The Trade Desk and Google’s Display & Video 360. By mid-2026, per official Spotify announcements, the company began transitioning Megaphone-hosted publishers to its proprietary ad stack, enabling them to traffic private marketplace (PMP) deals directly through the Spotify Ad Exchange.

Programmatic adoption in the audio sector has accelerated significantly to meet this new supply. According to a March 2026 study by Advertiser Perceptions, the proportion of agencies and advertisers buying audio programmatically reached 82%, a 100% increase from 2022. The Trade Desk has been a primary beneficiary of this trend, reporting in May 2026 that audio was its fastest-growing channel year-over-year in late 2025. This momentum is further bolstered by IAB/PwC data from April 2026, which notes that 71% of U.S. podcast creators now produce video versions of their shows, necessitating the omnichannel brand safety tools IAS is currently deploying.
