SpaceX - ticker SPCX - just completed the biggest IPO in American history, raising $75 billion at a $1.8 trillion valuation. Goldman Sachs projects $474 billion in revenue by 2030, while Morgan Stanley goes further - $3.4 trillion by 2040. But NYU's Aswath Damodaran, Wall Street's 'Dean of Valuation,' called those projections 'a hallucination.'

While every camera pointed at the rockets, Musk quietly placed a major bet on what he calls 'the world's biggest product' - something he believes could generate $30 trillion in revenue. Sixty of America's largest companies are making the same move, and the signal appeared in a quiet Friday SEC filing almost nobody noticed.
