Anthropic raises $580M Series B to advance AI safety and interpretability research (2022)

Anthropic raised $580 million in a Series B round in April 2022, led by Sam Bankman-Fried of FTX, to fund large-scale infrastructure for AI safety research. The company, then ~40 people, outlined work on interpretability, steerability, and robustness of large language models. The round is historically notable both for Anthropic's early safety-focused mission and for the involvement of Sam Bankman-Fried, who was later convicted of fraud in the FTX collapse.
