President Donald Trump rejected calls by AI industry leaders for stronger safeguards, calling fears about AI and data centers a hoax while arguing that U.S. leadership over China must take priority. Cohere CEO Aidan Gomez said AI models had become potent cyber weapons capable of finding and exploiting vulnerabilities at scale, while China opposed slowing development but supported stronger systems to manage security risks. The debate followed calls for restraint from Anthropic's Dario Amodei, OpenAI's Sam Altman, xAI's Elon Musk and Google DeepMind's Demis Hassabis. AI-related stocks fell as higher oil prices briefly lifted the 10-year Treasury yield above 5% before the Federal Reserve's decision, adding broader market pressure to concerns over AI investment.
