Katie Miller Attacked AI Rivals in 500 Posts While Holding $1 Million-Plus xAI Stake

Summary
$1 million-plus in xAI holdings sat behind Katie Miller’s nine-month barrage against ChatGPT, Claude and Gemini, a White House financial disclosure showed after she had posted nearly 500 times about rival AI products.
400-plus posts targeted OpenAI and Sam Altman, 64 hit Anthropic and 33 hit Google’s Gemini, while Miller posted positively about xAI and Grok 161 times; before buying the shares in December, she had rarely mentioned the companies.
FTC experts told The Washington Post she would ordinarily need to clearly disclose that financial tie when promoting xAI, though court rulings have weakened the agency’s ability to penalize violations.
The stake came after Miller began consulting for xAI in August 2025 and bought private-company shares on Dec. 19; her husband, White House deputy chief of staff Stephen Miller, is listed as recused from matters involving her holdings.
