Agencies Reclaim Control of Programmatic Ads

The initial promise of programmatic advertising—faster, smarter, and more accountable media buying—has been overshadowed by a complex and convoluted ecosystem. This web of DSPs, SSPs, data brokers, and various intermediaries has led to a significant disconnect between advertising spend and actual media placement. In fact, research has shown that publishers, on average, receive only 51% of the initial advertiser spend. This lack of transparency has real financial consequences, with one study from the Association of National Advertisers revealing that only 36 cents of every dollar entering a demand-side platform (DSP) ultimately reaches the consumer. The intricate and often opaque supply chains make it difficult for marketers to track where their budgets are going and which partners are adding value. This has resulted in a notable trust gap, with 57% of marketers expressing diminished confidence in the data from programmatic platforms. The shift towards in-housing programmatic functions is a direct response to these challenges. As of 2024, 25% of advertisers have brought their programmatic operations in-house, with 42% planning to increase their in-house trading capabilities. For agencies, the trend is even more pronounced, with a third now operating fully in-house trading desks to increase transparency and margins for their clients. The primary driver for advertisers is gaining better control over strategy and planning. The rise of Connected TV (CTV) is accelerating this move toward greater control and transparency. As substantial budgets flow into CTV, the existing inefficiencies and measurement issues within programmatic advertising have become more pronounced. U.S. programmatic video ad spending is projected to exceed $110 billion in 2025, making up nearly three-quarters of new programmatic ad revenue from 2024 to 2026. Artificial intelligence is playing a pivotal role in this new landscape, enabling more precise targeting and real-time optimization. AI-powered tools can analyze vast datasets to predict consumer behavior, automate bidding processes, and personalize ad creatives at scale. This allows agencies to move away from the "black box" model and offer more data-driven, efficient campaigns. Looking ahead, the focus is shifting to simplifying the programmatic supply chain. This involves reducing the number of intermediaries, fostering direct relationships with high-quality publishers, and leveraging technology for better decision-making rather than added complexity. The goal is a more transparent and efficient ecosystem where value is not lost in a convoluted supply path.
