Prediction text
AI sector will grow from $20T to $30-40T of $50T total US public market cap. | the US public market all companies combined is about 50 trillion. The AI companies are 20 trillion of the 50 trillion now. So, you know, it's incestuous, but it's like if that 20 trillion becomes 30 40 trillion, which it inevitably will, it's the majority of the market is just seven companies.
