Elon Musk's AI startup xAI has raised $10 billion in debt and equity funding to enhance its infrastructure and develop its Grok AI chatbot, which seeks to compete with rivals like OpenAI and Anthropic. The investment includes secured notes, term loans, and strategic equity, and supports the expansion of xAI's capabilities, including its supercomputer facility in Memphis. Musk has positioned Grok as a unique AI with a controversial stance, aiming to differentiate it from competitors.
