When the SpaceX and xAI S-1 filing hits the SEC in June, analysts will comb through supplier disclosures and this company's name is expected to surface. Dylan Jovine has identified the ticker and laid out the full investment thesis. The stock is still quiet - but that window may be closing fast.tc pixel
