That doesn't sounds like brilliant margins, to be honest. You've left out the entire "running a business" costs, plus the model training costs. They need to pay their staff, offices, and especially lawyers (for all the lawsuits over the scraped content used to train the models).

It's not unusual for a startup to not be profitable, and they're obviously not as the company doesn't make a profit, but I'm not sure why isolating one aspect of their business and declaring it profitable would justify the idea that this company is inevitably a good investment "even if the company went defunct tomorrow".

Perhaps you meant "win" in the sense of "being influential" or something, but I'm pretty sure the people who invested billions of dollars use definitions that involve more concrete returns on their investment.
