Motley Fool Warns of 'Historical Triple Whammy' Ahead of SpaceX IPO — June 18–30 Nasdaq Debut Targeted at $1.75T Valuation

On April 30, 2026, The Motley Fool published a high-profile investor warning identifying three historical risk patterns facing SpaceX's planned June IPO: (1) major IPOs including Facebook, Alibaba, GM, UPS, and Saudi Aramco historically declined 8-38% in their first six months post-debut; (2) SpaceX's estimated price-to-sales ratio at a $1.75 trillion valuation would reach 'high double digits or low triple digits' based on projected $15-16 billion in annual revenues — a level historically associated with speculative overvaluation; and (3) bubble-bursting events have preceded and followed every major technology investment wave over the past 30+ years. The article joins a growing body of institutional due diligence ahead of SpaceX's planned June 18-30 Nasdaq debut, where the company seeks to raise $75 billion — the largest US IPO in history. SpaceX is offering an unusual 30% retail tranche (vs. the standard ~10%), broadening access for individual investors. The public S-1 is expected around May 15-22, with a management roadshow the week of June 8 and IPO pricing between June 18-30. Morgan Stanley and Goldman Sachs are leading underwriters among 21 banks.
