OpenAI CEO Sam Altman’s House Targeted In Molotov Attack, Suspect Held Without Bail

San Francisco police have arrested a suspect for allegedly throwing a Molotov cocktail at the home of OpenAI CEO Sam Altman early Friday, the company said in a statement.

In a post on X, authorities said the incident occurred around 4 a.m. local time (11:00 GMT). The suspect allegedly hurled an improvised incendiary device at the property, setting part of an exterior gate on fire before fleeing on foot. About an hour later, police detained a 20-year-old man after receiving a report about someone threatening to burn down another building. Officials have not yet commented on a possible motive.

"Thankfully, no one was hurt. We deeply appreciate how quickly SFPD responded and the support from the city in helping keep our employees safe," an OpenAI spokesperson said.

Authorities have not yet publicly identified the suspect or confirmed the exact address of the attack. However, police said the individual was located near OpenAI's headquarters, roughly 4.8 kilometres (three miles) away, where he was allegedly making further threats to set a building on fire.

According to NBC Bay Area, citing a source familiar with the case, the suspect has been identified as Daniel Alejandro Moreno-Gama. He was taken into custody Friday afternoon and is being held without bail, as per San Francisco jail records. He faces multiple charges, including attempted murder, arson, criminal threats, and two counts each of possessing an incendiary device and a destructive device. OpenAI said it is cooperating with law enforcement agencies in the ong oing investigation.

Hours after the incident, Sam Altman responded publicly in a blog post, sharing a rare photo of his family. "Here is a photo of my family. I love them more than anything," he wrote in the post shared on X, alongside an image of his partner and child.

Altman said he hoped the post would discourage similar attacks in the future. "Images have power, I hope. Normally we try to be pretty private, but in this case I am sharing a photo in the hopes that it might dissuade the next person from throwing a Molotov cocktail at our house, no matter what they think about me," he added.

He also reflected on the impact of public narratives. "Words have power too. There was an incendiary article about me a few days ago. Someone said to me yesterday they thought it was coming at a time of great anxiety about AI and that it made things more dangerous for me. I brushed it aside," Altman said.

"Now I am awake in the middle of the night and upset, thinking that I may have underestimated the power of words and narratives," he added.

Notably, the incident comes at a time of heightened scrutiny for OpenAI. The company has recently faced criticism over reports of a deal with the U.S. government to allow its technology to be used in classified military operations, following tensions involving rival Anthropic. A recent NBC News poll also found that artificial intelligence remains less popular among the public compared to agencies like U.S. Immigration and Customs Enforcement.
