The supervisor of New York City's pension funds, one of the largest in the United States, asked Anthropic to postpone its stock market debut until risks posed by its artificial intelligence technology are better controlled. A small fraction of those assets, around $7 million, are currently exposed to Anthropic, the Comptroller's office told AFP. However, that exposure will grow if Anthropic goes public because its shares would become included in several stock indices, including the Russell 3000, which New York City tracks for its own investments.
