FBI: Texas Suspect Targeted OpenAI CEO Sam Altman Over AI ‘Existential Risk,’ Faces Attempted‑Murder and Federal Explosives Charges
A 20‑year‑old man, identified as Daniel Moreno‑Gama of Spring, Texas, is accused of traveling to San Francisco early Friday and throwing a Molotov‑style device at OpenAI CEO Sam Altman’s Russian Hill home, briefly setting an exterior gate on fire before the device extinguished and no one was hurt. San Francisco police and federal agents say Moreno‑Gama then went to OpenAI’s headquarters, smashed doors and threatened to burn the building, and was arrested nearby carrying a jug of kerosene and a lighter. He has been charged in state court with counts that include attempted murder and attempted arson, and federal prosecutors have pursued explosives‑related and unregistered‑firearm charges; the FBI executed a search warrant at his Texas home as investigators collected evidence. Authorities say they recovered a multi‑page manifesto and other writings in which the suspect named executives and investors at AI companies and argued that advanced AI poses an existential threat to humanity.
The arrest and the contents of the document have pushed the case beyond a late‑night property crime to a warning about politically‑tinged anti‑technology extremism. The suspect’s writings reportedly described “our impending extinction,” and prosecutors and experts have linked the incident to a broader pattern in which opposition to technology—spanning ideologies that endorse sabotage and arson—can harden into violent acts. That danger is set against a public debate in which concern about AI is uneven: one survey at a Harvard event found median perceived existential risk from advanced AI rose from 50% to 70% among participants and nearly all agreed mitigation should be a global priority, while the 2026 AI Index found a majority saw more benefits than harms from AI but that 52% of respondents reported feeling nervous about the technology in 2025. Officials have warned of the risk of copycat attacks, and local prosecutors and U.S. attorneys have signaled they will pursue the case aggressively, with some even raising the possibility of domestic‑terrorism charges if the evidence supports it.
Initial news reports focused on the incident as a discrete attack on property, with scant detail about motive; subsequent reporting by outlets including The Wall Street Journal and NPR — and confirmations from Fox News, CBS and others — disclosed the manifesto, the alleged targeting of Altman by name, and the broader anti‑AI rationale, reframing the episode as part of a rising threat of anti‑tech violence. The expanded coverage shifted attention to the implications for security around high‑profile tech executives and for public rhetoric about AI: Altman himself posted a family photo and urged de‑escalation while acknowledging public fear about AI, and social media responses ranged from calls to address underlying anxieties to satirical critiques and warnings that the backlash could turn physically dangerous.
📊 Relevant Data
In a March 2026 survey of 89 participants at a Harvard University event, the median perceived probability of existential risk from advanced AI (causing extinction or severe disempowerment if developed unimpeded) was 50% before the event and rose to 70% after, with 96% agreeing post-event that mitigating AI existential risk should be a global priority.

According to the 2026 AI Index Report, globally, the share of respondents who say AI products and services offer more benefits than drawbacks rose from 55% in 2024 to 59% in 2025, while 52% reported feeling nervous about AI in 2025.

Anti-technology extremism, including opposition to AI, spans ideologies such as insurrectionary anarchism, eco-extremism, and eco-fascism, advocating violent actions like sabotage and arson against tech infrastructure, with recent trends showing potential for political violence driven by perceptions of technology as an existential threat.

📌 Key Facts
- Early Friday (around 3:45–4:00 a.m.) a Molotov‑style incendiary device was thrown at OpenAI CEO Sam Altman’s San Francisco Russian Hill residence; the device briefly set an exterior gate on fire, burned out, caused minimal damage and no injuries were reported.
- Authorities say 20‑year‑old Daniel Moreno‑Gama of Spring, Texas, traveled to San Francisco, was arrested outside OpenAI’s headquarters carrying a jug of kerosene and a lighter, and FBI agents executed a search warrant at his Spring, Texas, home as part of the investigation.
- Investigators recovered a written ‘anti‑AI’ document or multi‑part manifesto from Moreno‑Gama that listed names and addresses of AI executives, investors and board members and included language about AI posing an existential risk to humanity (including a section titled ‘Some more words on the matter of our impending extinction’).
- According to court and law‑enforcement accounts, after the residential attack Moreno‑Gama went to OpenAI’s San Francisco office, threw a chair at glass doors, threatened to burn the building and kill people inside, and surveillance images cited in the federal complaint show him allegedly committing those acts.
- Moreno‑Gama faces state charges including two counts of attempted murder (allegedly targeting Altman and a security guard) and attempted arson — charges that, per the San Francisco district attorney, could expose him to 19 years to life — and federal charges for possession of an unregistered firearm and damage and destruction of property by means of explosives (penalties cited up to roughly 10 and 20 years respectively); federal prosecutors said they could pursue a domestic‑terrorism enhancement if evidence supports it.
- The federal criminal complaint includes surveillance images and the seized written materials as evidence tying Moreno‑Gama’s actions to his stated anti‑AI motives; law‑enforcement officials have described the attack as a targeted act rather than a random property crime.
- Separately, two people (Amanda Tom and Muhamad Tarik Hussein) were arrested in connection with a reported gunshot near Altman’s home in an incident investigators say is unrelated to the Molotov attack; police used surveillance to trace the vehicle and seized firearms at their residence.
- Sam Altman posted a blog entry including a family photo urging de‑escalation of rhetoric around AI; law‑enforcement and experts warned the Molotov attack represents a serious escalation and cautioned about the risk of copycat attacks, while prosecutors pledged to pursue the case to the fullest extent of the law.
