A contrarian view suggests Google's core search ad product has degraded for a decade, relying on its monopoly. In contrast, talent from more innovative ad platforms like Meta, now at OpenAI, could enable OpenAI to be more agile in creating a new, more compelling advertising model for the LLM era.

According to Ben Thompson's Aggregation Theory, OpenAI's real moat is its 800 million users, not its technology. By monetizing only through subscriptions instead of ads, OpenAI fails to maximize user engagement and data capture, leaving the door open for Google's resource-heavy, ad-native approach to win.
Google has caught up in AI technology, but its biggest hurdle is strategic. Integrating generative AI threatens its core search advertising model, which accounts for 80% of revenue. This creates an innovator's dilemma where they must carefully disrupt themselves without destroying their cash cow.
While competitors focus on subscription models for their AI tools, Google's primary strategy is to leverage its core advertising business. By integrating sponsored results into its AI-powered search summaries, Google is the first to turn on an ad-based revenue model for generative AI at scale, posing a significant threat to subscription-reliant players like OpenAI.
While other AI companies are hesitant, Google is expected to lead LLM ad integration. As a company built on ads, it is culturally positioned to implement monetization quickly and effectively, unlike competitors that may view ads as a necessary evil rather than a core competency.
OpenAI plans to personalize ads not just on immediate queries but by analyzing a user's entire chat history. This creates a powerful hybrid of Google's intent-based advertising and Meta's interest-based profiling, going beyond simple sponsored links to offer deeply contextual promotions.
Ben Thompson's analysis suggests OpenAI is in a precarious position. By aggregating massive user demand but avoiding the optimal aggregator business model (advertising), it weakens its defense against Google, which can leverage its immense, ad-funded structural advantages in compute, data, and R&D to overwhelm OpenAI.
As competitors like Google's Gemini close the quality gap with ChatGPT, OpenAI loses its unique product advantage. This commoditization will force them to adopt advertising sooner than planned to sustain their massive operational costs and offer a competitive free product, despite claims of pausing such efforts.
The long-term monetization model for consumer LLMs is unlikely to be paid subscriptions. Instead, the market will probably shift toward free, ad- and commerce-supported models. OpenAI's challenge is to build these complex new revenue streams before its current subscription growth inevitably slows.
Analyst Eric Sufert predicts OpenAI's ad model will not be anchored to the content of a user's query, which could compromise trust in the answer's objectivity. Instead, it will function like Instagram's feed, where ads are targeted based on a user's broader conversion history, independent of the immediate conversational context.
While Google aggressively pushes AI search, this new model lacks a proven advertising equivalent. This creates a fundamental tension where product innovation directly threatens its primary revenue source. Google's greatest strength—its search monopoly—is also its greatest vulnerability in the AI transition.
