By investors. OpenAI and Anthropic are not profitable (Anthropic is profitable if you allow them to invent what profitability means).
Investment is not a subsidy. Words still have meanings. Nobody in this thread has successfully answered the question: subsidized by whom?

I heard someone calling the key metric in Anthropic financial reports EBBT: Earnings Before Bad Things[1] :-)
[1] Where "Bad Things" would be the typical interest, taxes, depreciation, amortisation plus the Anthropic specific employee compensation, LLM training (you know, for the LLM lab), revenue sharing agreements (which is a form of paying for infrastructure), etc.
