While tech giants could technically replicate Perplexity, their core business models—advertising for Google, e-commerce for Amazon—create a fundamental conflict of interest. An independent player can align purely with the user's best interests, creating a strategic opening that incumbents are structurally unable to fill without cannibalizing their primary revenue streams.

Tech giants like Google and Meta are positioned to offer their premium AI models for free, leveraging their massive ad-based business models. This strategy aims to cut off OpenAI's primary revenue stream from $20/month subscriptions. For incumbents, subsidizing AI is a strategic play to acquire users and boost market capitalization.

AI summaries provide answers directly on the search page, eliminating the user's need to click through to publisher websites. This directly attacks the ad revenue, affiliate income, and subscription models that have funded online content creation for decades.

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.

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.

Your reliance on Google AdWords is a critical vulnerability. As user attention shifts from traditional search to AI-powered chat, search volume will drop, competition for remaining traffic will intensify, and your customer acquisition costs will skyrocket. This isn't a future problem; it is happening now.

Amazon's potential commerce partnership with OpenAI is fraught with risk. Allowing ChatGPT to become the starting point for product searches threatens Amazon's highly profitable on-site advertising revenue, even if Amazon gains referral traffic. It's a classic battle to avoid being aggregated by another platform.

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.

OpenAI's partnership with Stripe to enable in-app purchases transforms ChatGPT from an information tool into a transactional platform. This creates a frictionless sales channel for e-commerce brands, directly challenging Google's established search-to-purchase business model.
