San Francisco police arrested a 20-year-old man early Friday morning after he allegedly threw a Molotov cocktail at the home of OpenAI chief executive Sam Altman, setting fire to an exterior gate before fleeing.
Officers responded to the property in the North Beach area — part of Altman’s Russian Hill estate, purchased for $27 million in 2020 — shortly after 4 a.m. following reports of the incendiary device.
No one was injured, and the fire was contained to the gate. Altman himself was not at home.
A spokeswoman added that the same person had “also made threats at our San Francisco headquarters”.
Less than an hour later, the same suspect appeared at OpenAI’s headquarters on Third Street, where he allegedly threatened to burn down the building. Officers recognised him from the earlier incident and arrested him on the spot.
OpenAI confirmed the attack targeted Altman’s residence and issued a statement: “Thankfully, no one was hurt. We deeply appreciate how quickly SFPD responded and the support from the city in helping keep our employees safe.” The company is assisting law enforcement with the investigation.
The suspect has not been publicly named, and charges are still pending.
The incident underscores growing anxieties surrounding public figures in the technology industry, particularly those at the forefront of artificial intelligence development. As AI continues to reshape economies, politics, and daily life, its leading voices have increasingly become lightning rods for both admiration and hostility.
Security experts note that while Silicon Valley has long been associated with innovation and ambition, it is not immune to the darker currents of public backlash.
There has been no official statement from Altman at the time of publication. It is understood that security measures around the property have been reviewed and reinforced following the incident.
This incident comes amid heightened scrutiny of Altman and OpenAI, including recent controversies over military contracts and ongoing legal battles.
