The potential for OpenAI's advertising business is staggering. A back-of-the-envelope calculation suggests that at their scale, monetizing just 0.22 ads per prompt (one in five) at a plausible $50 CPM for high-intent discovery would generate $25 billion in revenue, rivaling established ad giants.

Internal projections reveal ads are a core long-term strategy, not an experiment. OpenAI expects "free user monetization" to generate $110 billion through 2030, with average revenue per user (ARPU) growing from $2 to $15. Gross margins are targeted at 80-85%, mirroring Meta's highly profitable ad business.

While a 4% fee seems reasonable for new customer acquisition, it becomes a burden if users who discovered a product organically then use ChatGPT for checkout convenience. This dynamic forces merchants to pay OpenAI for customers they didn't acquire through the platform.

By integrating shopping into ChatGPT, OpenAI can become a massive e-commerce engine. With a potential take rate of 15-30%, similar to Amazon or Meta, capturing just 20% of the $1.2T U.S. e-commerce market would generate tens of billions in new, high-margin revenue.

OpenAI's 4% fee for in-app purchases creates a risk for merchants. If consumers start using ChatGPT as their primary purchasing interface, it could intercept sales that originated from a brand's own marketing. A customer might see a product elsewhere, then buy it via ChatGPT, imposing a new tax on an otherwise organic conversion.

OpenAI's path to profitability isn't just selling subscriptions. The strategy is to create a "team of helpers" within ChatGPT to replace expensive human services. The bet is that users will pay significantly for an AI that can act as their personal shopper, travel agent, and financial advisor, unlocking massive new markets.

The high price point for professional AI tools is justified by their ability to tackle complex, high-value business tasks, not just minor productivity gains. The return on investment comes from replacing expensive and time-consuming work, like developing a data-driven growth strategy, in minutes.

OpenAI has a strategic conflict: its public narrative aligns with Apple's model of selling a high-value tool directly to users. However, its internal metrics and push for engagement suggest a pivot towards Meta's attention-based model to justify its massive valuation and compute costs.

OpenAI is more public and aggressive with its shopping features (partnering with Shopify, DoorDash) than its ad strategy. By first attracting thousands of merchants to its e-commerce waitlist, it's establishing a foundational transaction layer. This de-risks its future ad platform by ensuring a ready base of paying customers.
