xAI, Elon Musk's AI company, completed a massive $20 billion Series E funding round, valuing it at about $230 billion with investors like Nvidia, Cisco Investments, and others. The funds will support AI infrastructure expansion including Colossus I and II supercomputers and training Grok 5, leveraging data from X's 600 million monthly active users. At CES 2026, the focus was on "AI everywhere" with a strong emphasis on AI-first hardware and integration between NVIDIA and Hugging Face's LeRobot for robotics development. The Reachy Mini robot is gaining traction as a consumer robotics platform. In software, Claude Code is emerging as a popular local/private coding assistant, with new UI features in Claude Desktop and innovations like Cursor's dynamic context reducing token usage by nearly 47% in multi-MCP setups. "The 600 million MAU figure in xAI’s announcement combines X platform users with Grok users. That’s a clever framing choice."
