Katie Miller has spent the better part of a year waging a one-woman war against the biggest names in artificial intelligence. OpenAI’s ChatGPT, Anthropic’s Claude, Google’s Gemini: all of them, in her telling, are dangerously biased, ideologically captured, and unfit for public consumption. What she hasn’t told her audience is that she holds roughly $1 million in stock in the company selling what she frames as the solution.
That company is xAI, Elon Musk’s AI venture and maker of the Grok chatbot. The Washington Post reported the undisclosed stake on September 10, raising pointed questions about the line between political commentary and paid promotion.
The campaign by the numbers
Since December 2025, Miller has published approximately 500 posts targeting AI chatbots made by xAI’s direct competitors. The criticisms hit a familiar rotation: the models are too liberal, they produce “woke” outputs, they pose safety risks to children, and they’ve been linked to harmful outcomes including suicide-related incidents.
Miller’s professional history makes the arrangement particularly awkward. She served as a special government employee with Musk’s Department of Government Efficiency from 2024 through May 2025, working as a communications liaison. After leaving that role, she moved into communications work at xAI itself. Her husband, Stephen Miller, serves as deputy chief of staff in the White House.
