Agentic audio media buying Market: Butler/Till pilots AI media buying for audio with iHeart
Independent agency Butler/Till and iHeartMedia ran a four-week pilot in July–August 2026 testing agentic AI media-buying agents on streaming audio and podcast inventory for an unnamed U.S. agricultural client. The pilot used two matched AI agents (one from Butler/Till, one from iHeartMedia) connected via an MCP server and executed just under $10,000 in media buys via a direct agency-to-publisher purchase. Butler/Till reported a 42% reduction in campaign CPMs versus the client’s direct-buy benchmark and a higher share of premium non-skippable mid-roll podcast placements (48% vs an estimated 33% in the traditional plan). iHeartMedia said it will expand inventory availability — including broadcast radio later in 2026 — and make its Audiograph solution available through Amazon’s DSP from mid-September.
Pilot demonstrates measurable efficiency gains (42% CPM reduction) and expands agentic AI testing into audio/podcast inventory with a direct agency-to-publisher buy; signals potential industry adoption though programmatic audio remains a limited share of total audio spend.
