A man has been charged with attempted murder after allegedly throwing a Molotov cocktail at the San Francisco home of OpenAI CEO Sam Altman, federal and local authorities announced. No one was reported injured in the attack, which caused damage to the property. The suspect was identified and law enforcement moved quickly to take action.

The FBI conducted a raid on a home in Texas connected to the suspect as part of the investigation. Federal charges are being considered in addition to the state-level attempted murder charge, reflecting the seriousness with which authorities are treating the case.

Investigators are scrutinizing a post on Substack that the suspect allegedly authored, which may shed light on his motivations for targeting Altman specifically. Altman is one of the most prominent figures in the artificial intelligence industry, leading OpenAI, the company behind ChatGPT.

Altman acknowledged the incident publicly, and OpenAI has not made extensive comment beyond confirming awareness of the attack. The case has drawn significant national attention given Altman's high profile and the broader climate of tension surrounding the rapid growth of AI technology and its leading figures.
