The number nobody's bragging about (Ad)

SPCX - the largest IPO in history - was predicted to open at $175. It opened at $150. Insiders bought in at a $20 billion valuation; IPO buyers paid $1.77 trillion. The math for 1,000% gains simply isn't there. But one small publicly traded company - with a $1.5 billion backlog - builds the power infrastructure Musk's Colossus can't run without, and Wall Street hasn't priced it in yet. The last time a stock like this got discovered, it was Vertiv, which ran 1,700%. Dylan Jovine is giving away the ticker name, free.tc pixel
