[EDIT: The original title of this question was: "If FTX/Alameda currently control Anthropic, who will end up controlling it?". Based on the comments so far, it does not seem likely that FTX/Alameda currently control Anthropic.]
If I understand correctly, FTX/Alameda have seemingly invested $500M in Anthropic, according to a Bloomberg article:
FTX/Alameda were funneling customer money into effective altruism. Bankman-Fried seems to have generously funded a lot of effective altruism charities, artificial-intelligence and pandemic research, Democratic political candidates, etc. One $500 million entry on the desperation balance sheet is “Anthropic,” a venture investment in an AI safety company. [...]
That seems consistent with the following excerpts from this page on Anthropic's website:
Anthropic, an AI safety and research company, has raised $580 million in a Series B.
The Series B follows the company raising $124 million in a Series A round in 2021. The Series B round was led by Sam Bankman-Fried, CEO of FTX. The round also included participation from Caroline Ellison, Jim McClave, Nishad Singh, Jaan Tallinn, and the Center for Emerging Risk Research (CERR).
Is it likely that FTX/Alameda currently have >50% voting power over Anthropic? If they do, who will end up having control over Anthropic?
