Programmatic buying won the last decade because it made media cheaper to transact and easier to scale. That bet paid off. EMarketer projects programmatic will account for effectively all net-new display ad dollars in 2025, underscoring just how fully automation has become the default operating system for digital advertising. But programmatic's biggest promise was never automation for its own sake. It was accountability. Spend a dollar, see what it did, then adjust quickly.

As marketing ecosystems grow more complex and accountability pressures increase, programmatic advertising is at a pivotal moment. Brands and agencies are being asked to justify marketing budgets faster, optimize more precisely and demonstrate impact when campaigns are still active, not weeks after budgets are depleted. However, many programmatic workflows remain rooted in post-campaign analysis. Activation happens in one place, measurement in another and insight arrives only after outcomes are set.

And, often, the value of this data increases when it's nested within a larger company. For example, Infillion acquired Catalina this week, as it plans to infuse its DSP. In some ways, the MediaMath DSP- Catalina data combo emulates Amazon, whose DSP is superpowered by its ecommerce sales data.

Today's programmatic landscape has fractured into a maze of silos, proprietary ecosystems and walled gardens, each one extracting value, controlling access and making it harder for marketers to see where their dollars actually go. Meanwhile, open internet programmatic, once the promised land of clarity and control, has been reduced to a fraction of the overall media mix. This wasn't inevitable. It was engineered.

The ad industry is racing toward a not-too-distant future where AI agents negotiate programmatic deals on their own - and Prebid doesn't want publishers to get left behind. The group that turned header bidding software into an open-source standard announced on Thursday that it's taking ownership of code developed using Ad Context Protocol (AdCP) that will power publisher-side AI agents.
