Suspect Arrested for Allegedly Throwing Molotov Cocktail at Sam Altman’s Home

Incident Overview

San Francisco police have arrested a 20-year-old man suspected of attacking the home of OpenAI CEO Sam Altman. Authorities report that in the early hours of Friday, the suspect threw an incendiary device that landed near Altman’s property and briefly caught an exterior gate on fire. Thankfully, the flames were quickly extinguished and caused only minor damage; no one was hurt in the incident.

Threats at OpenAI Headquarters

After the attack at Altman’s residence, a person matching the suspect’s description appeared outside OpenAI’s headquarters in the Mission Bay neighborhood. There, the individual reportedly made threats against the building, including statements about intending to burn it down. Security personnel at OpenAI promptly alerted authorities, who detained the man on site.

Employee Safety and Company Response

OpenAI’s security team quickly informed staff about the situation and advised heightened caution, including reminders not to allow any unauthorized entry into the building. Employees were also told to expect an increased presence of law enforcement and security around the office while police continue their investigation. The company’s offices remain open during this period.

Background and Recent Security Incidents

This attack is the latest in a series of security concerns for OpenAI. Last November, the company went into lockdown due to a threat from an activist, and in February 2025, protesters were arrested for blocking entrance doors at the San Francisco office. OpenAI, in coordination with law enforcement, continues to strengthen its security protocols in response to these events.
