NextFin News - A series of seismic shifts converged in the third week of February 2026, fundamentally altering the power dynamics of the $700 billion global advertising industry. OpenAI officially transitioned its ChatGPT advertising business from a pilot phase into a live reality, with confirmed brand placements appearing in user responses as of February 20. Simultaneously, The Trade Desk’s flagship supply-path initiative, OpenPath, suffered a major blow as two of the world’s largest advertising holding companies, WPP and Dentsu, quietly exited the program. These events unfolded against the backdrop of Google’s aggressive expansion of AI-automated controls and the first earnings report from the newly merged Omnicom-IPG entity, which now stands as the world’s largest agency holding company with annual revenues of $17.5 billion.
According to Adweek, search intelligence firm Adthena confirmed that ads from major brands including Expedia, Qualcomm, Best Buy, and Enterprise Mobility began appearing in approximately 0.8% of ChatGPT responses this week. OpenAI is commanding a premium for this inventory, requiring a minimum spend of $200,000 and setting CPM rates at $60—roughly three times the average rate on Meta’s platforms. While OpenAI’s monetization lead, Asad Awan, has framed the long-term vision as a conversational tool for small businesses to bypass traditional agency interfaces, the current pilot is heavily supported by holding companies like Omnicom Media Group, which has already secured over 30 client placements. This paradox—agencies funding the very technology that aims to automate their roles—highlights the industry's current state of flux.
The friction in the programmatic space became evident on February 20 when it was revealed that WPP and Dentsu had withdrawn from The Trade Desk’s OpenPath. The initiative was designed to provide direct access to publisher inventory, bypassing sell-side intermediaries. However, the holding companies cited a lack of transparency and the presence of hidden fees as primary reasons for their departure. According to Digiday, when data, identity, and measurement layers are fully loaded, The Trade Desk’s effective platform fees can reach 20%, a cost that large-scale buyers are increasingly unwilling to absorb. This retreat comes at a sensitive time for The Trade Desk, whose stock has declined significantly from its peak amid rising competition from Amazon’s DSP.
The structural realignment is further evidenced by the Omnicom-IPG merger, which CEO John Wren described during the February 18 earnings call as a "data-led AI transformation." The combined entity is aggressively pursuing $1.5 billion in cost savings over the next 30 months, largely through the elimination of approximately 7,200 roles and the integration of AI into creative workflows. CTO Paolo Yuvienco noted that AI now allows creative teams to generate up to 50 concepts for a client in the time it previously took to produce three. This drive for efficiency mirrors the broader policy environment under U.S. President Trump, whose administration has championed an "accelerate-at-all-costs" approach to AI, often at the expense of traditional regulatory guardrails.
The divergence between OpenAI’s rising influence and The Trade Desk’s programmatic struggles suggests a shift toward "agentic" advertising. In this new model, the conversational interface becomes the primary point of contact, potentially rendering the complex web of supply-side platforms and agency intermediaries obsolete. The fact that Dentsu and WPP are pulling back from OpenPath while simultaneously writing six-figure checks to OpenAI indicates that the industry's largest spenders are betting on AI-driven surfaces over traditional open-web programmatic channels. However, OpenAI still faces significant hurdles, particularly the lack of a standard attribution system or tracking pixels, which makes measuring conversion in a conversational environment a persistent challenge.
Looking forward, the industry is likely to see a deepening divide between "closed-loop" AI ecosystems and the "open" programmatic web. Google’s recent moves to tighten AI-automation grip over advertiser controls suggest that the search giant is preparing for a future where human intervention in ad placement is minimal. As the 2026 midterm elections approach, the U.S. President Trump administration’s deregulatory stance is expected to further empower these AI platforms to scale rapidly. For agencies, the path forward lies in the successful integration of identity solutions like Acxiom’s Real ID into AI workflows, attempting to prove their value as data orchestrators even as the platforms they use attempt to automate the very essence of their business.
