Magnite (NASDAQ: MGNI) said on September 8 that it ran its first agentic ad campaign in EMEA with Amnet France, cutting setup time by roughly 70% and returning a 95% video view-through rate on a premium CTV buy for an unnamed leading automotive manufacturer. The statement, distributed through GlobeNewswire, is the first production-scale case study of the pattern the ad-tech industry has been narrating for two years: agents on both sides of the transaction, talking to each other in place of humans clicking through settings.

Amnet’s traders used natural-language prompts to instruct Magnite’s buyer agent, which then built and activated the campaign through ClearLine. Magnite’s Orchestration layer handled the handshake between buyer agent and seller agent, replacing manual publisher selection and deal structuring. The company said the agent also surfaced inventory and optimisation opportunities that wouldn’t have appeared in a traditional manual workflow, which is the more interesting claim: not just faster, but reaching different supply.

“As AI continues to mature, we wanted to understand how agentic technology could deliver practical value and complement the way we operate today,” said Barbara Thuillier-Romeri, Ad-Tech Manager at Amnet France. Edouard Schmidt, Magnite’s Commercial Director for France, said the buyer agent is “embedded directly into the buying workflow” and that Magnite intends to extend the pattern to further EMEA clients.

Two things to hold in view. Amnet France, founded in 2012, works with more than 200 advertisers, this was an agency deployment on premium CTV, not a self-serve product. Magnite has announced no availability, pricing, or timeline for broader access. The 70% number is a trading-desk figure. But the direction of travel from bespoke agency pilot to platform default is the well-worn route programmatic itself took after 2010, and it rarely reverses.
