Suspect Arrested After Molotov Cocktail Thrown at Home of OpenAI CEO Sam Altman
A 20-year-old suspect was found at the company's headquarters, where he was threatening to burn down the building.
Apr 10, 2026
A suspect was arrested in San Francisco Friday after being accused of throwing a Molotov cocktail at the home of Sam Altman, the CEO of the artificial intelligence firm OpenAI.
The 20-year-old man was found at the OpenAI headquarters about three miles away from Altman's home, where he was threatening to burn down the building, San Francisco police said.
The device the suspect threw onto Altman's property in the Russian Hill neighborhood caused a fire on the exterior gate. It was unclear whether Altman and his family were at home.
The suspect was in custody Friday, with charges pending.
Altman's company and other companies have been under fire as AI has expanded rapidly at President Donald Trump's urging, with the president issuing an executive order attacking states' ability to regulate the industry.
Experts have warned the expansion of generative AI threatens jobs and democracy, with political campaigns already using the technology to create fraudulent media in advertisements.
Massive, energy-sucking AI data centers have also been blamed for higher household electricity bills and water consumption.
Protesters have rallied against Altman's company for agreeing to provide its technology to the Department of Defense.
In November, The New York Times reported, a person who had once been associated with the anti-AI group Stop AI "expressed interest in causing physical harm to OpenAI employees," causing the company to lock down its headquarters.
On Friday, Stop AI condemned the attack on Altman's house and emphasized that the group "seeks to protect human life."
"We do not condone any violence whatsoever," said the group. "We pray everyone involved in this situation puts aside violence and finds peace, and we continue to hope the AI industry stops the development of frontier AI systems in the interest of public safety and the preservation of humanity. To the best of our knowledge, this incident did not involve anyone who has ever been associated with our group. And this action is wholly inconsistent with our values."
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, The U.S. is on a fast track to authoritarianism like nothing I've ever seen. Meanwhile, corporate news outlets are utterly capitulating to Trump, twisting their coverage to avoid drawing his ire while lining up to stuff cash in his pockets. That's why I believe that Common Dreams is doing the best and most consequential reporting that we've ever done. Our small but mighty team is a progressive reporting powerhouse, covering the news every day that the corporate media never will. Our mission has always been simple: To inform. To inspire. And to ignite change for the common good. Now here's the key piece that I want all our readers to understand: None of this would be possible without your financial support. That's not just some fundraising cliche. It's the absolute and literal truth. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. Will you donate now to help power the nonprofit, independent reporting of Common Dreams? Thank you for being a vital member of our community. Together, we can keep independent journalism alive when it’s needed most. - Craig Brown, Co-founder |
