Do you trust major AI companies to keep their employees and the public safe?

OpenAI and Anthropic have instructed employees to conceal company badges and logos in public, with OpenAI also issuing security training that warns staff about espionage approaches involving money, friendship, or romance. The precautions follow incidents including protests outside OpenAI's San Francisco offices and attacks targeting CEO Sam Altman's home.

Why it matters

The measures reflect growing concern among artificial intelligence companies about espionage, unwanted approaches, and hostility toward people working in the field. For San Francisco residents, the steps highlight how security concerns are reaching everyday public spaces where tech workers commute, dine and socialize.

Anthropic disclosed in its stock-market listing filing that it spent $2.7 million on personal security services for CEO Dario Amodei. The extraction does not report whether this spending changed from prior periods or how it compares with peer companies.

The players

OpenAI

OpenAI is an artificial intelligence research company based in San Francisco that developed the ChatGPT chatbot and is among the most prominent developers of advanced AI models.

Anthropic

Anthropic is an artificial intelligence safety company based in San Francisco that develops the Claude family of AI models and has been preparing a public stock-market listing.

Sam Altman

Sam Altman is the chief executive of OpenAI and one of the most visible figures in the global artificial intelligence industry.

Dario Amodei

Dario Amodei is the chief executive of Anthropic and a former OpenAI executive who co-founded Anthropic in 2021.

The details

OpenAI instructed staff not to wear items carrying its logo outside the office, while Anthropic reminds workers to hide badges and has largely restricted branded merchandise. Employees are also told to use privacy screens on public transport and erase meeting-room whiteboards before leaving, and Anthropic has reported people trying to photograph its offices.

March 2026: Activists wrote messages outside OpenAI's San Francisco offices urging staff to quit over its Pentagon agreement.
April 2026: Sam Altman's home was targeted in two separate incidents, with a suspect allegedly throwing a Molotov cocktail at the property.
Two days after the first April incident: Two suspects were accused of firing a shot outside Altman's home.

Under the Hood

Anthropic's $2.7 million disclosure of personal security spending for its CEO, filed as part of its stock-market listing, places AI firms within a broader pattern of companies publicly documenting executive protection costs. The move signals that security expenses are becoming a formal line item for frontier AI developers rather than an incidental cost.

For employees, the guidance changes daily habits such as keeping badges out of sight, using privacy screens on transit, and clearing whiteboards before leaving a meeting room. Readers who work in or visit AI offices may notice tighter restrictions on photography and branded clothing around these sites.

The takeaway

Security training for tech workers increasingly covers personal conduct outside the office, not just digital safeguards. Employees at AI companies should treat unsolicited approaches, especially those involving money or personal relationships, as a reason to report rather than engage.
