A 20-year-old suspect has been charged in California Superior Court after allegedly carrying out a firebomb attack on the San Francisco home of OpenAI CEO and openly gay Sam Altman. The attack happened in the early hours of Friday, April 10. According to prosecutors, the attacker threw a lit Molotov cocktail at Altman’s property around 3:40 a.m., before targeting OpenAI’s headquarters the same morning.
The suspect, identified as Daniel Moreno-Gama, was detained by San Francisco police later that day. Authorities say he now faces multiple charges, including attempted murder and arson. Officials have described the incident as a targeted attack, reportedly motivated by fears about artificial intelligence.
Court filings allege Moreno-Gama was carrying writings outlining plans to harm Altman and referencing concerns about AI causing “impending extinction.” Prosecutors say the materials also included threats toward other tech leaders, along with their addresses. Federal authorities have indicated additional charges, including possible domestic terrorism. The situation escalated on Sunday, April 12, when Altman’s home was targeted again in a separate incident involving a reported gunshot fired from a passing car. Two individuals were arrested shortly after.
In response, Altman shared a photo of his husband and young child on his blog, expressing hope to discourage further violence.
