Google overtakes OpenAI as top AI partner for marketing agencies
According to research from Forrester and the 4As, Google has overtaken OpenAI, Adobe, Microsoft, and Anthropic as the preferred AI partner for US marketing agencies. Agencies are shifting their focus from standalone models to integrated operating systems that unify data, creative tooling, and media activation across platforms. This structural change impacts how ad-tech workflows, synthetic content, and video ad creatives are orchestrated and delivered.
Key Takeaways
- Google's lead is driven by its full-stack integration of Gemini and Veo models with Google Analytics 360 and YouTube.
- Major agency holding companies including WPP, Omnicom, and Publicis now use Google's infrastructure to power their internal operating systems.
- Adobe is pivoting to interoperability by expanding its Content Supply Chain with APIs for third-party platforms like Google.
- OpenAI faces 'infrastructure-dependency' risks as its models are increasingly abstracted behind partner platforms and agency tools.
- Anthropic is focusing on enterprise trust and 'Claude Code' agent capabilities to differentiate itself within regulated industries.
Why It Matters
Marketing agencies are moving away from 'best-in-class' standalone AI tools in favor of end-to-end orchestration platforms that can handle high-volume video ad creatives and real-time media buying. For the streaming video industry, this suggests that the next phase of monetization will be won by providers who can seamlessly bridge the gap between generative creative tools like Google’s Veo and downstream ad-insertion on platforms like YouTube. As AI moves from a creative assistant to an ‘operating system,’ the ability to unify creative iteration with performance measurement becomes the primary competitive barrier. Watch for whether OpenAI can successfully launch a direct ad-buying platform to monetize ChatGPT traffic and avoid becoming mere sub-infrastructure.
Additional Context
The transition toward AI-enabled 'operating systems' coincides with a rapid commercialization phase for conversational search and generative video. Per Digiday in June 2026, OpenAI recently updated its 'Ad Tools Term Document' to introduce AI-powered creative tools that automate the mass production, localization, and translation of ad creatives. This move responds to the launch of its self-serve Ads Manager in May 2026, which dropped campaign minimums from $50,000 to zero, signaling a push for broader market adoption. Meanwhile, rival ad-tech firms such as Criteo have also slashed ChatGPT-related spend requirements from $50,000 to $10,000 as of early June 2026 to capture early performance-marketing budgets. Simultaneously, competitors are sharpening their focus on specific segments of the marketing lifecycle. Adobe announced 'Adobe Brand Visibility' in June 2026, a platform integrating Semrush data to help brands optimize how they are cited in AI-generated answers. According to Adobe's June 2026 updates, the company is also expanding its 'Firefly Graph' to help enterprise teams build repeatable, scalable creative workflows within Photoshop and Premiere. This focus on the high-end content supply chain contrasts with Anthropic’s June 2026 release of enterprise-managed authorization features via Okta, which streamlines deployment for thousands of internal agency employees at once. Google’s recent 'AI Mode' integration into Search and the rollout of Gemini-powered conversational discovery ads (per PPC Land, June 2026) further solidify its grip on the full-funnel experience. By combining cinematic-grade video generation via Veo with direct activation on YouTube Shorts, Google is effectively collapsing the workflow from creative production to media delivery. As of June 2026, Forrester reports that every major agency holding company, including Dentsu and WPP, now relies on Google to enhance their own proprietary AI stacks, highlighting a move toward ecosystem consolidation.
