Let's say I own a lemonade stand. I sell you a 20% stake.
My stand loses $10. When I report my financial results, I report losing $10. Then I report that your share of those losses is $2, and my share is $8. This creates transparency.
So OpenAI really did lose $8.8B or whatever, but some of those losses are 'attributed' to other shareholders/owners of their subsidiaries, because they have a complicated corporate structure. So they report both numbers - the total loss, and then the part they 'own'.
So when Ed says "It’s unclear what this means", he's either terribly uninformed or intentionally misleading his readers into thinking something fishy is going on when it isn't.
Either way, it's bad journalism - if you don't know what it means, shouldn't you try to find out or ask an expert or something and then inform your readers? (And the thing is, it would easy enough to dunk on them for losing $8 billion, without adding these weird insinuations!)
