The math on the SpaceX IPO is broken (Ad)

SpaceX is expected to go public at a $1.75 trillion valuation. For investors to see a 10x return, the company would have to reach $17.5 trillion - more than Apple, Microsoft, and Nvidia combined. But there may be a smarter play: a tiny supplier, just 1/60th the size of SpaceX, has already shipped 5 billion critical components to the company over the last decade. Once SpaceX goes public this June, Wall Street analysts will likely tear through the supply chain and put this under-the-radar vendor on the map.
