I don't think you realize the issue. They aren't monetizing their SaaS product satisfactorily -- hence the Amazon cash flow imbalance statement. This indicates they must find new markets to survive. Despite this, however, they are gaining only in poorer markets, limiting the monetizability of a high cost product.
Implementing adds is a hail-mary. It puts them in a knife fight with google which will likely result in a race to the bottom which OpenAI cannot sustain and win.
FB global ARPU is about 50 USD. At 700M customers, they do 35B in revenue annually. This compares to a publicly stated expected cost of approximately 150B in computing alone over the next 5 years (see: https://fortune.com/2025/09/06/openai-spending-outlook-115-b...). This leaves a profit of 5B per year, with 90B expected r&d costs. Even if OpenAI develops a product and fires all employees, you are looking at a ROIC of about 18 years.
Fundamentally, OpenAI does not have the unit economics of a traditional SaaS. "Hundreds of millions of users" is hundreds of millions of people consuming expenses and not generating sufficient revenue to justify the line of business as a going concern. This, coupled with declining enterprise AI adoption (https://www.apolloacademy.com/ai-adoption-rate-trending-down...) paints an ugly picture.
Facebook users spend multiple hours per day doomscrolling. Operational costs of a doomscrolling user is minimal. Most of it will be served from a CDN.
Imagine 700M users “doomchatting” with GPT5 for several hours per day to justify the ROI of advertising.
