CNBC's Kate Rooney reports that California Attorney General Rob Bonta has opened an investigation into Elon Musk's xAI over its Grok chatbot allegedly facilitating non-consensual sexually explicit deepfake images, including images of minors. The AG questions whether xAI took adequate steps to prevent misuse of the technology. xAI has not publicly responded, while Musk addressed the matter on social media last week. The report also notes xAI raised about $20 billion last week and says the controversy may threaten its enterprise partnerships while adding to existing investigations.
