Sen. Bernie Moreno writes to Dario Amodei attacking Anthropic's 'alarmist' superintelligence warnings ahead of its IPO
On Oct 5, 2026 Sen. Bernie Moreno (R-Ohio) sent Anthropic CEO Dario Amodei a letter accusing him of an "alarmist approach" and "panic-inducing commentary" on superintelligence (SI). He called it hypocritical to invite millions of Americans to invest in Anthropic's IPO, at a valuation near $2 trillion, while warning that its product could cause their extinction. He urged Anthropic to focus on how SI can strengthen US security against China.
Key facts
- Letter dated Oct 5, 2026, released by Moreno's office ('Moreno Blasts Anthropic CEO for Hypocritical Approach to Super Intelligence'), first obtained by Axios (Stef W. Kight)
- Key line: 'I do not understand how you can ask them to invest their hard-earned savings in Anthropic's continued development while warning those same Americans that your product could ultimately lead to their extinction.'
- Cites Jacob Coxon's resignation post ('the people building AI earnestly believe that it could kill us all by the end of the decade'), Evan Hubinger's reply ('>10% within the next decade'), Amodei on CNN ('I agree with Jacob Coxon on far more than I disagree with him') and Amodei's 25% chance that SI goes 'really, really badly'
- IPO framing: 'a valuation approaching $2 trillion (about 42 times Anthropic's revenue and double what the company was worth four months ago), and trading expected as soon as October 2026'
- Uses the administration's new 'super intelligence (SI)' terminology; praises Anthropic for signing the White House Accord on Super Intelligence as 'a notable first step' and applauds Trump's 'commitment to American dominance in responsible SI development'
- Asks Anthropic to stop 'publicly pontificating the worst-case scenario' and to stress solutions to 'the real vulnerabilities SI has found in American critical infrastructure and cybersecurity'
- Axios: 'the latest example of President Trump's allies targeting Amodei'; Ohio colleague Sen. Jon Husted faces midterm ads attacking him as pro-data-center
What happened
Moreno's letter follows weeks of attacks on Amodei's "doomerism" by administration allies, even as Trump himself warmed to Amodei after their Sept 27 dinner. The letter does not ask for a reply by a set date. It mixes criticism of Amodei's risk statements with praise for the White House's voluntary accord.
Why it matters
It ties Anthropic's safety messaging directly to its IPO. Warnings that the technology could be catastrophic, which also appear as risk factors in the leaked prospectus, are recast as a reason investors should distrust the company. This line of attack will likely follow the listing.
