Jim Cramer Warns SpaceX IPO Could Trigger Dot-Com-Style Collapse

Benzinga reported Friday that CNBC host Jim Cramer is sounding a loud alarm over the SpaceX IPO bubble risk building in equity markets. Speaking on Mad Money, Cramer cautioned that an upcoming SpaceX public listing could ignite dangerous speculative excess across the broader market.

Cramer Flags SpaceX IPO Bubble Danger

SpaceX is reportedly eyeing a June 12 Nasdaq debut, accompanied by a 5-for-1 stock split to lower the per-share entry price. Its IPO prospectus could land as early as next week. Current private-market estimates place the company’s valuation between $1.75 trillion and $2 trillion. Cramer warned that if underwriters release too few shares, pent-up demand could drive that figure toward $5 trillion, creating what he called “a bubble unto its own.”

A Warning Rooted in Dot-Com History

Cramer drew direct parallels to the late 1990s technology boom, when underwriters deliberately restricted share supply to manufacture first-day price surges. That artificial scarcity fed a speculative frenzy that later collapsed between 2000 and 2002, wiping trillions of dollars from global markets. He urged today’s underwriters to price deals responsibly and avoid repeating those same tactics. “Too much supply and the market breaks down,” Cramer said, adding that irresponsible pricing in the other direction carries equal risk.

Broader Tech IPO Pipeline Amplifies Concern

The concern extends well beyond SpaceX alone. Both Anthropic and OpenAI are separately weighing public listings, and Cramer suggested a rush of major tech offerings could pressure investors to liquidate existing positions. That rotation of capital could weigh on the broader equity market regardless of individual company quality. Venture capitalist Chamath Palihapitiya has voiced similar unease over speculative excess in what could become a crowded IPO window.

Private Gains, Public Risk

SpaceX’s private-market trajectory sharpens the equity risk calculation. The company has already delivered roughly fivefold appreciation in private markets, climbing from approximately $350 billion to its current target valuation. Most retail investors missed that entire run. A public listing now resets the valuation clock at levels that leave limited upside for new buyers and maximum exposure to any sentiment shift. Analysts tracking private markets suggest the listing could also recalibrate benchmarks across AI, defense and advanced computing sectors.
