DeepSeek's rise has cost tech billionaires significantly, with Elon Musk losing $90 billion, followed by Jensen Huang and Mark Zuckerberg, who lost $20 billion and $11 billion, respectively. The AI startup's success led to a $600 billion drop in Nvidia's market value, marking one of the largest declines in US stock history. Despite the financial fallout, Huang praised DeepSeek for its innovation and impact on global enthusiasm for AI, while major clients like Meta, Amazon, Google, and Microsoft plan to invest $320 billion in AI and data centers.
