On April 10, 2026, reports revealed that a Molotov cocktail was thrown at OpenAI CEO Sam Altman’s San Francisco residence. The incident marks one of the most direct physical threats against a leading figure in the artificial intelligence industry to date.
According to the San Francisco Police Department (SFPD), the attack occurred around 3:45 AM at a North Beach residence linked to Altman. While the fire was contained to the exterior metal gate and self-extinguished, the suspect didn't stop there. Roughly an hour later, police were called to OpenAI’s Mission Bay headquarters, where a man matching the suspect’s description allegedly threatened to burn the building down, per multiple reports.
