OpenAI CEO Sam Altman’s home was targeted in two separate incidents in April 2026, according to the report. Meanwhile, Anthropic disclosed in its stock-market listing filing that it spent $2.7 million on personal security services for CEO Dario Amodei, the report added. Anthropic has also reported people trying to photograph its offices, adding to concerns about how easily workers can be identified. In one incident reported by The Wall Street Journal, a stranger approached an OpenAI employee at a San Francisco playground and gradually steered the conversation towards work.
OpenAI has instructed staff not to wear items carrying its logo outside the office, while Anthropic reminds workers to hide their badges and has largely restricted branded merchandise, according to the New York Post. Anthropic and OpenAI are reportedly telling employees to conceal company badges and logos in public. The precautions come amid concerns about espionage, unwanted approaches and hostility towards people working in artificial intelligence (AI). OpenAI’s security training warns that spies may offer money, friendship or romance to obtain confidential information. The guidance reportedly concerns attempts to exploit personal relationships, not a ban on employees forming them. OpenAI’s security sessions describe methods ranging from overhearing conversations in cafes to bribery and attempts to build personal relationships. The publication claimed that the person was a spy. Employees are also reminded to use privacy screens on public transport and erase meeting-room whiteboards before leaving. The precautions also come against a backdrop of hostility towards AI companies and their employees. In March, activists wrote messages outside OpenAI’s San Francisco offices urging staff to quit over its Pentagon agreement. One suspect allegedly threw a Molotov cocktail at the property and subsequently threatened OpenAI’s headquarters. Two other suspects were accused of firing a shot outside his home two days later. All three were arrested and charged, pleaded not guilty and are awaiting trial.
