U.S. lawmakers are calling for stronger AI regulation after former Anthropic researcher Jacob Coxon warned that OpenAI and Anthropic are "gambling with our lives" and AI could lead to human extinction by the end of the decade.

More than 20 members of Congress called for stronger AI regulation this week, with Massachusetts Democratic Representative Lori Trahan stating on Friday that bipartisan support has reached a "tipping point." Coxon resigned from Anthropic on Tuesday, and his post on X has garnered over 150 million views.

Chris Lehane, OpenAI's Head of Global Affairs, posted on Wednesday calling for "mandatory, capability-based national regulation." U.S. President Donald Trump on Thursday dismissed concerns that AI could lead to human extinction, stating, "If we don't win in AI, we're going to be in a very bad situation."
