I was right about SpaceX (Ad)

Jeff Brown predicted Bitcoin before it climbed as high as 52,400%, Tesla before 2,150%, and Nvidia before 32,000%. Now he says SpaceX is shaping up to be the biggest IPO of the decade - and three key milestones just confirmed it. In the past 21 days: SpaceX crossed 10,000 active satellites, Elon filed confidential IPO paperwork with the SEC, and another rocket launched 25 more satellites. Two-thirds of every satellite in orbit now belongs to one company. The public filing could drop any day.tc pixel

Before you buy SpaceX shares, consider this alternative approach (Ad)

SpaceX has confidentially filed for an IPO with the SEC, targeting a June 2026 listing at a valuation exceeding $1.75 trillion - potentially the largest IPO in history. But one expert says buying shares directly may not be the smartest move. There is a lesser-known way to tap into this windfall that most investors haven't considered.tc pixel
