Summary

On April 10, 2026, Daniel Moreno-Gama, 20, allegedly attacked OpenAI CEO Sam Altman's San Francisco home with a Molotov cocktail and later attempted to break into OpenAI headquarters with kerosene and an anti-AI manifesto. Moreno-Gama, who traveled from Spring, Texas, was arrested and charged with attempted arson and attempted murder, facing potential life imprisonment. His parents stated he was experiencing a mental health crisis. This incident is the most prominent attack against an AI-related individual or business amid growing public discontent with artificial intelligence. Altman addressed the attack in a blog post, sharing a family photo and calling for de-escalation in the AI debate. Federal authorities are investigating the incident as a potential act of domestic terrorism, while Moreno-Gama's public defender argues it is an overcharged property crime stemming from mental illness.
