SAN FRANCISCO — A man was arrested Thursday after throwing a Molotov cocktail at the residence of OpenAI CEO Sam Altman in the United States, authorities said.
The incident occurred at approximately 6:44 p.m. local time on April 10, 2026. Police responded to reports of a fire at the property in Altman's neighborhood. Upon arrival, officers found the suspect in the vicinity of the home. No injuries were reported among residents or first responders.
The suspect, whose identity has not been released, was taken into custody without incident. He is being held on charges related to arson and attempted assault. Investigators are examining the circumstances surrounding the attack, including the suspect's motive and any potential connections to broader security concerns regarding high-profile technology executives.
OpenAI did not immediately comment on the incident. Altman was not home at the time of the attack, according to neighbors who spoke to reporters. The property sustained minor damage, primarily to the exterior of the home and landscaping. Fire crews extinguished the blaze quickly, preventing significant structural harm.
This incident marks one of the most direct attacks on a major artificial intelligence leader in recent years. Altman has been a central figure in the global AI development landscape, leading OpenAI through rapid expansion and increased public scrutiny over the technology's safety and regulation.
Law enforcement officials have not disclosed whether the suspect acted alone or as part of a larger group. The investigation is ongoing, with authorities reviewing surveillance footage and interviewing witnesses. No claims of responsibility have been made by any individual or organization.
The attack has raised questions about the security measures in place for prominent figures in the tech industry. While many executives have faced online threats and protests, physical attacks remain rare. Security experts suggest that increased visibility and public controversy surrounding AI development may have contributed to the incident.
Neighbors described the scene as chaotic, with emergency vehicles surrounding the property and smoke rising from the front yard. Some residents expressed concern over the safety of the community, noting that the area had previously been quiet.
Authorities have urged anyone with information about the suspect or the incident to come forward. The case is being treated as a high-priority investigation, with federal agencies potentially involved given the target's profile.
