Digital ad platforms now call themselves agentic but keep over 70 percent of ad spend. Are these companies really acting in your interest or just repackaging old tactics?
Digital ad platforms now market themselves as "agentic"-autonomous, goal-driven, and supposedly working for the advertiser. But these same platforms routinely keep more than 70 percent of every ad dollar, often through transaction chains that are nearly impossible to audit. The core issue isn’t just technology, but trust: can a platform that profits so heavily from your budget ever truly act as your agent?
According to a 2025 industry benchmark, only 41% of programmatic ad investments reach genuine, measurable, viewable impressions, while 26.1% is lost to DSP fees, data costs, and SSP costs.
The new wave of programmatic companies didn’t just build on that legacy. Many set up business models that put their own margins first. They added dashboards, jargon, and attribution reports that made every campaign look successful-while quietly taking most of the money. Content owners and publishers lost ground, while platforms collected undisclosed fees and profits from arbitrage.
Now, with "AI" and "agentic" as the latest marketing terms, these same platforms are rebranding. They promise autonomy and alignment with advertiser goals. In practice, not much has changed. The platforms still act as principals, not agents, and their incentives are still at odds with their clients. The new language is mostly cosmetic.
In a high-profile antitrust case, Judge Leonie Brinkema on September 2, 2026, declined to force Google to sell its AdX exchange, where publishers pay a 20% commission to Google for instant transactions at page load. This decision highlights the entrenched position of major platforms and the significant fees they extract from the digital advertising ecosystem.
It’s not enough for a platform to call itself "agentic" if its business model is built on extracting as much value as possible from its own clients. The industry has already seen how technical jargon and slick interfaces can hide self-serving practices. If you wouldn’t trust a company with your family’s interests, why trust it with your ad budget? The only real solution is radical transparency and a return to true agency-where the client’s goals, not the platform’s margins, come first.
