Why Anthropic Broke With Sam Altman: Dario Amodei Says Trust Collapsed

In Bloomberg's interview, Amodei is asked about the moment at an AI summit in India when he appeared to refuse a handshake with Altman. His explanation is almost comically literal: the summit was run in a state of extreme confusion, speaker positions and sequence changed at the last minute, and after the photos they were suddenly told to join hands.

He invokes the image of Prime Minister Narendra Modi unexpectedly urging everyone to hold hands, emphasizing that international summits with heads of state often descend into this kind of staging chaos. While careful not to single out India for criticism, he gently pushes back on media readings that tried to assign deeper meaning to the moment.

Amodei says that some players in the industry are more trustworthy than others, and that Anthropic is not the only one he would put in that category. His ideal outcome is a system in which trusted actors first align with one another and then push less trusted players into a position where they have little choice but to adopt the same standards.

Even if some participants would not choose the right behavior on their own, a trustworthy majority can structure the field so the rest have no real alternative. It is a pragmatic view of existential-risk coordination, one that relies less on goodwill than on incentives and industry structure.

On the question that has become Silicon Valley folklore, why he left OpenAI, Amodei says that disagreement over safety alone is not enough to justify leaving a company. Internal differences of opinion are normal.

What proved decisive, he says, was a collapse of trust. If you feel you cannot trust the other party, that their professed values do not match reality, that they are not acting with integrity, or that they show unsettling behavioral patterns, then continuing to work at that company becomes very difficult. If two sides share neither vision nor trust, his conclusion is that they should stop fighting, go separate ways, and let the market and public opinion render the verdict.
