The Man Who Firebombed Sam Altmans House Had a Hit List of AI CEOs. The FBI Is Warning All of Them.

Federal charges reveal a three-part anti-AI manifesto with names and home addresses of tech executives and investors.

The AI Post newsroom — delivering AI news at the speed of intelligence.

The 20-year-old who threw a Molotov cocktail at Sam Altmans San Francisco home last Friday was not having a bad day. He was executing a plan. A plan he wrote down, flew 1,800 miles to carry out, and intended to be just the beginning.

Federal prosecutors have now charged Daniel Moreno-Gama with possession of an unregistered firearm and attempted destruction of property by means of explosives. But the charges are not the story. The manifesto is.

A Three-Part Manifesto With a Kill List

According to an FBI affidavit reviewed by Business Insider, police recovered a three-part document from Moreno-Gama at the time of arrest. Part one was titled "Your Last Warning" followed by his full name. In it, he allegedly claimed to have "killed/attempted to kill" Altman, then wrote: "If I am going to advocate for others to kill and commit crimes, then I must lead by example and show that I am fully sincere in my message."

The document listed names and home addresses of AI company CEOs, board members, and investors. At a joint press conference on Monday, FBI Acting Special Agent in Charge Matt Cobo confirmed the bureau has contacted every person on the list and delivered safety warnings. The agency declined to release the names for security reasons.

Part two was titled "Some More Words on the Matter of Our Impending Extinction" and laid out what Moreno-Gama believed were existential risks from artificial intelligence. Part three was a letter addressed directly to Altman that began with "if you make it" and told the OpenAI CEO that surviving would be "a sign from the divine to redeem yourself."

He Lurked in San Francisco for Days

The SF Standard reports that Moreno-Gama checked into a Union Square hotel on April 6, a full four days before the attack. He stayed two nights, checked in again on Thursday, then left at 2:34 a.m. Friday dressed entirely in black with a backpack. Surveillance footage captured him throwing the incendiary device at Altmans Russian Hill home. The fire scorched a driveway gate but did not reach the interior.

About ninety minutes later, he appeared at OpenAI headquarters, smashed the glass doors with a chair, and told on-site security he came to "burn it down and kill anyone inside." Police arrested him carrying additional incendiary devices, a jug of kerosene, a blue lighter, and the manifesto. The FBI subsequently raided his family home in Texas and recovered a handgun from his downtown SF hotel room.

Then Someone Else Shot at the Same House

Two days after the firebombing, a second attack targeted the same residence. Police arrested two suspects in connection with a shooting at Altmans home on Sunday morning and found three additional firearms at their residence. It is not yet clear whether the two incidents are connected. But two attacks on the same home in 72 hours is not coincidence. It is a pattern.

This Is Not a Lone Wolf. This Is Ideology.

Here is the part that should worry every AI executive reading this: the manifesto was not the scribbling of a confused person. It was a structured, multi-part document that diagnosed a problem (AI as existential threat), prescribed a solution (violence against its creators), and provided a target list with home addresses. That is not mental illness. That is ideology with operational planning.

The anti-AI backlash has been building for months. Data center opposition has escalated from town halls to arson and gunfire. Maine voted to ban them entirely. A councilman had his house shot up while his 8-year-old was inside. Now the founders themselves are being targeted with kill lists.

Altman responded on his blog, calling for de-escalation while acknowledging that "fear and anxiety" about AI are "justified." He drew a connection between the New Yorker profile published days earlier and the attack, saying he had "underestimated the power of words and narratives."

But here is the uncomfortable truth nobody in Silicon Valley wants to say out loud: you cannot build the most powerful technology in human history, tell the world it might end civilization, raise $122 billion to do it anyway, and then act surprised when someone takes you at your word. The AI industry manufactured the fear. Now the fear has its own manifesto, its own hit list, and its own soldiers willing to act on it.

The question is no longer whether anti-AI extremism exists. It is whether Friday was the beginning or the peak.

Moreno-Gama is set to appear in San Francisco federal court this week. The FBI says the investigation is ongoing.
