They were, but then Anthropic got so much flack in the business press for omitting them publicly (while sharing them privately with potential subscribers) that the bad PR was as bad as the financials themselves.
Which was probably the right move. The S-1 didn't seem to really change the overarching economic and financial narratives about Anthropic (it seems like whatever people already felt before the S-1, they felt it even more after looking at it).
So I don't think there's going to be any problem with boosters metabolizing the Q3 numbers.
(Idk, maybe this was their plan from the jump.)
