Magnite CTV programmatic growth now drives over half of total contribution

The shift of over half of Magnite's contribution to CTV confirms that programmatic automation is no longer a secondary channel for major streamers like Netflix and Paramount. By integrating SpringServe and AI-driven orchestration, Magnite is positioning itself as the essential middleware for a fragmented market that now includes retail media and in-flight entertainment. This transition suggests that the 'open web' model of automated bidding is successfully migrating to the high-stakes environment of premium video. Watch for how potential regulatory changes to Google's ad tech stack impact Magnite's DV Plus business relative to its insulated CTV operations.

Magnite's connected television business has attracted significant attention from investors and industry analysts as US CTV ad spend accelerates across major streaming platforms. In Q2 2025, Magnite reported CTV contribution ex-TAC grew 14% year over year, driven by increased programmatic activity from buyers seeking premium video inventory, reinforcing the company's position as the largest independent sell-side platform in the CTV ecosystem. The company's SpringServe ad serving technology, acquired in 2021, now underpins delivery for partners including Disney, Roku, and Warner Bros. Discovery, giving Magnite a structural advantage in server-side ad insertion for live and on-demand streaming.

On the business and competitive front, Magnite has been expanding beyond traditional CTV into adjacent monetization verticals. The company announced a partnership with Viasat Aviation in early 2025 to bring programmatic advertising to in-flight entertainment screens, opening a new inventory category that few SSPs can address. Meanwhile, Magnite's DV Plus platform, which provides demand-side access to CTV inventory for agencies and brands, saw adoption from Walmart's retail media arm and JioHotstar in India, signaling that the company is positioning itself as a full-stack programmatic layer rather than a pure sell-side intermediary. Competitive pressure remains intense, with FreeWheel (owned by Comcast) and PubMatic both investing heavily in CTV-specific ad serving and programmatic infrastructure during the same period.

From a technical and measurement standpoint, Magnite's Orchestration platform represents its effort to automate the operational complexity of CTV ad delivery. The platform uses AI-driven workflow automation to manage ad pod assembly, frequency capping, and yield optimization across simultaneous streaming sessions, reducing the manual configuration that has historically slowed programmatic CTV adoption. This matters because CTV ad loads are more complex than display or mobile video, with strict pod structures, content adjacency rules, and platform-specific requirements from each streaming partner. Magnite's ability to automate these workflows at scale is a key differentiator as advertisers shift budgets from linear TV to addressable streaming inventory.
