$800M a year is less than 1% of their quoted revenues at $100B+ / year. Claiming credits as revenue would be tax fraud. Credits to clients for services are counted as debits against
There are zero serious companies collecting $1000 on revenue and sending $999 as a cost of goods sold to Anthropic/AI. It would be unprofitable to even run a proxy to Anthropic on such thin margins. But I digress.
No company was banking $100 and keeping $99 in the "before times" either. These are fantasy numbers not even the most highly optimized software company produced. As an example, Slack famously went public in 2019 and it had revenue of $401M with a gross margin of ~79%, meaning they were pulling in $316M in gross profit. That is the figure before labor, administration, R&D, sales & marketing, etc. They actually operated on a net loss after factoring for those expenses, despite their high gross margin, which is common in high growth startups (Amazon famously ran losses or marginal profits until decades after their founding because they continuously reinvested in expansion).
Credits reduce revenue by all basic accounting standards. You can accuse these companies of fraud, it is within the realm of possibility, but it would also be You are making conflicting arguments at the same time. There exist startups that are able to generate gross profit with some consumption of AI services, they are also able to invest nearly 100% of their capital into AI to generate those profits without needing to spend on traditional labor, and yet AI is not sustainable. By your own circular logic it is of course sustainable, but by grounded logic, you have to understand any business that goes from zero 4 years ago to $100B+ in annual revenue today with double digit growth rates is offering the world something of value. Anyone who has tried AI sees some value in it. There is some revenue and profit to be made here. Betting against that in the long term will just lose you money and sanity.
