I think that is correct, and exactly why these purported margins are nonsensical. If Anthropic's reported $50 billion in revenue is majority per-token billing, and tokens have a margin of 80%, that would put Anthropic's profit at $30 billion on per-token usage. Where is that $30 billion going?
And conversely, let's look at the amount Anthropic are spending on compute. Anthropic has just started paying SpaceX $1.25 billion per month for compute. At an 80% profit margin that would mean Anthropic is going to be bringing in $6.25 billion per month... that's more than their current reported revenue.
And that's just one contract for compute. We know that Anthropic also pay Google ~$3 billion per month for compute (based on their committed spend of $200bn over 5 years) which is $36 billion per year. At $36 billion per year on compute with 80% margins that would put revenue at... $180 billion.
Add in their spend with Amazon and Microsoft, Anthropic are spending at least $4 billion per month on compute, or $48 billion per year, all but equal to their revenue. If margins on tokens are 80% and an estimated $37.5 billion of revenue is per-token revenue, that needs just $7.5 billion of compute per year, less than $1 billion per month.
The numbers just don't add up. If margins are 80% and they have $48 billion per year in compute spend, revenue should be over $200 billion.
If the 80% margin made any sense whatsoever, Anthropic would be printing money, yet they're losing money, and have only been profitable for one month based on some financial engineering (pre-commitments billed after the fact to reduce their costs during one month).
My guess is margins are closer to 20% than 80%. That's the only way any of the numbers can make sense.
