Magnite’s CTV Surge Signals Programmatic Shift as Retail Media Scales

The programmatic advertising landscape reached a significant inflection point in the final quarter of 2025, characterized by the decisive dominance of Connected TV (CTV) over legacy digital formats. Magnite’s latest earnings report serves as the primary evidence for this transition, with CTV contribution ex-TAC growing 32% year-over-year (excluding political spend). For the first time in the company’s history, CTV has surpassed the DV+ segment—which includes desktop, mobile, and display—to become Magnite's largest business unit, representing 48% of total contribution. This is not merely a internal shift for one firm; it reflects a broader advertiser migration toward the 'sight, sound, and motion' of the living room, where targeting capabilities now rival the precision of social media.

Industry context reveals that this growth is coming at the direct expense of traditional display. Magnite’s DV+ segment saw a 1% decline in the fourth quarter, a trend management explicitly attributed to budget shifts toward CTV. As programmatic spend consolidates, the 'middle class' of digital display is being squeezed, forcing platforms to innovate or face obsolescence. Magnite is responding by leaning into the adCP protocol and SpringServe technology to deepen its integration with streaming giants, positioning itself as the essential plumbing for the post-cable era. The 43% Adjusted EBITDA margin reported by Magnite suggests that as CTV scales, the operational leverage inherent in these platforms is finally beginning to manifest in significant cash flow.

Magnite’s guidance for Q1 2026, forecasting CTV growth of up to 31% while DV+ is expected to decline by as much as 8%, suggests that the divergence between high-value video and legacy display will only widen.

Parallel to the CTV surge is the evolution of the performance and retail media network (RMN) model. Ibotta’s Q4 results provide a masterclass in the 'network-as-a-service' pivot. While its direct-to-consumer (DTC) revenue fell 26%, its third-party publisher redemption revenue grew 8%. By integrating its performance network into high-traffic platforms like DoorDash and Instacart, Ibotta grew its total redeemer base by 19% to 20.4 million. This strategy signals a move away from the 'destination app' model toward an 'everywhere' commerce layer. For advertisers, this means the ability to trigger incentives at the point of purchase across a fragmented ecosystem of delivery and grocery apps, rather than relying on a single siloed platform.
