Sam Altman’s San Francisco Home Targeted in Arson Attack

San Francisco police arrested a man on April 10, 2026, following an arson attack at the residence of OpenAI CEO Sam Altman and subsequent threats to burn down the company’s corporate headquarters.

The incident began in the early hours of April 10, when an incendiary device, identified as a Molotov cocktail, was thrown at Altman’s home in the North Beach and Russian Hill area of San Francisco. According to the San Francisco Police Department, officers responded to a fire at the residence near Chestnut and Jones streets at approximately 4:12 a.m. PT.

The device caused a fire on an exterior gate of the property, which has been valued at $65 million. Police reported that the suspect fled the scene on foot immediately after the attack. No injuries were reported as a result of the fire.

Arrest at OpenAI Headquarters

Approximately one hour after the attack at the residence, police responded to reports of a man threatening arson at OpenAI’s headquarters in the Mission Bay neighborhood. Officers recognized the individual as the same suspect involved in the attack at Altman’s home.

The suspect, identified as a male between 20 and 25 years old, was taken into custody at the office. Witnesses reported that multiple police vehicles remained near the 400 block of Mission Bay Boulevard until at least 9:30 a.m. PT on April 10, with the area taped off by law enforcement.
