CNBC's Jim Cramer Predicts SpaceX IPO Will Double to $4 Trillion. He Says Two Factors Will Lead to Massive Buying.

Jim Cramer foresees SpaceX's IPO doubling to a $4 trillion opening valuation, while cautioning investors not to chase a spike. Goldman Sachs remains the lead underwriter and Morgan Stanley handles the retail allocation. SpaceX plans to raise about $75 billion and is set to debut on NASDAQ roughly a week after the segment, using a fixed price of $135 that implies a $1.77 trillion valuation rather than a traditional range. That fixed-price structure replaces book-building and moves price discovery to the first trade.

Cramer points to a tiny float due to lock-up agreements and to forced index-fund demand once SpaceX lists. The S-1 shows founder and insiders have a 366-day post-IPO lock-up, while most other holders face 180 days under the underwriters’ control. He warns the IPO could resemble a 1999-like spike followed by a pullback, citing Cerebras’ IPO as a cautionary example. He also notes his own SpaceX exposure via markets and says a day-one doubling is plausible but risky.
