Amazon structured their entire operation to look like this but as you indicated, could have switched to a porfit-making, dividen-paying company more than a decade ago, that just wasn't their strategy. The same can not be said for OpenAI. Even if they slashed their R&D, their marketing and sales costs are extremely high for a tech company. On paper they look more like a utility and those are not worth double-digit multiples; they compete with t-bills and GICs
Looking at the fact that third parties are making a profit offering XYZ third party open models on OpenRouter, it stands to reason that OpenAI could turn off their R&D, marketing, hype jedi, legal departments and just sell GPT9.999 and turn a profit.
Again like in the Amazon analogy, I don't think they're done growing, and unfortunately, I think they've positioned themselves (perhaps intentionally) as too big to fail, and need to continue growth at all costs.
I'm glad I'm not OAI's CFO sounds like a stressful job trying to justify/account for whatever Sam says to the board, or whatever the board demands. Sam hasn't said hardly anything since about February so I'm guessing the CFO simply bends to the will of the board these days. But that's speculation.
