Who really controls AI: The $25 trillion empire behind Nvidia, OpenAI, and Musk

A renewed global debate over AI control has erupted after Anthropic CEO Dario Amodei urged legislative limits on powerful systems, drawing immediate White House criticism. President Donald Trump said slowing progress would only benefit China. The AI ecosystem spans hardware makers like Nvidia, TSMC, and AMD, cloud providers such as Microsoft and Amazon, and software firms including OpenAI and Google DeepMind. The top 10 public AI companies now hold a combined market value of $25 trillion. Nvidia leads with a $5.1 trillion valuation, followed by Apple at $4.86 trillion. Private firms Anthropic ($965 billion) and OpenAI ($852 billion) are preparing public listings, while Elon Musk's xAI is valued at $250 billion.
