You can look up ASC 810-10-45.
OpenAI isn't a single company. I haven't followed all the details with its structure change/recapitalization, but it's (I believe) a parent sitting on top of an LLC that outside investors like Microsoft hold a large minority stake in.
The rules say that the parent has to report 100% of the LLC's revenue and expenses as if it owned everything and then, at the end, back out the share of the loss that economically belongs to the minority holders.
So $8.84 billion is the whole loss, $3.74 billion is approximately the outside members' proportional share of it, and $5.09 billion is what's left for the parent. Nothing disappeared or was hidden. It's one number presented two ways because two sets of people own it.
OK interesting. Who specifically are these other subsidiaries that clearly account for this loss though? I get it's just a trueism for those in the know like you, but it's pretty fascinating for me at least! Like is there one example company we can point to here? Even if there were like 20 subsidiaries and the combined loss was 3 billion, that would feel noteworthy on its own?
Like to be absolutely honest, this point ends up just sounding more alarmist than the claim you took issue with originally. But perhaps I am just misunderstanding.
