Market Chatter: Japan to Hold Urgent Meeting with Megabanks, BOJ, TSE Chief Over Anthropic's Mythos AI Risks

By

Finance Minister Satsuki Katayama will meet on Friday with Japan's three largest lenders - Mitsubishi UFJ (8306), Sumitomo Mitsui (8316), and Mizuho (8411)- to discuss risks related to Anthropic's AI model Mythos, Bloomberg News reported on Wednesday.

Bank of Japan Governor Kazuo Ueda and Japan Exchange Group (TYO:8697) CEO Hiromi Yamaji are also expected to attend, the news wire said, citing people familiar with the matter.

Katayama told reporters on Wednesday that the discussion will begin with sharing assessments of the situation and exchanging views on issues raised in the US and concerns across the international financial community, the publication said.

The meeting follows global regulators' response to cybersecurity flaws exposed by Mythos, which has had only a limited release, with Katayama warning that malicious actors could exploit its power, the report said.

Mythos, Anthropic's newest model under its Claude AI system, is reportedly capable of outperforming humans at certain hacking and cybersecurity tasks, according to various reports.
