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. Get the full details on this overlooked supplier before the June IPO.tc pixel

Elon’s big June 30 announcement (Ad)

Most investors are focused on the historic $1.75 trillion SpaceX IPO expected around June 30. But there's a lesser-known angle that could matter more to your portfolio. One under-the-radar tech firm has already shipped 5 billion critical components to SpaceX - making it a linchpin of the operation. Because SpaceX has been private, this partnership has gone almost entirely unnoticed by Wall Street.tc pixel
