Jim Cramer Warns SpaceX IPO Could Spark Market-Wide Bubble
CNBC reported Friday that “Mad Money” host Jim Cramer raised fresh alarm bells over the forthcoming SpaceX public offering, arguing the deal could generate destructive, bubble-like conditions across the broader equity market.
Cramer Flags Speculative Excess After Cerebras Spike
Cramer’s concerns sharpened following the blockbuster first-day trading session for AI chipmaker Cerebras Systems on Thursday. He said the SpaceX IPO bubble risk is now even greater given that retail and institutional appetite for high-profile tech listings appears supercharged. SpaceX is widely expected to debut in June, with its prospectus potentially arriving as early as next week. Cramer argued that if underwriters release only a thin slice of shares, demand could push the company’s implied market value as high as $5 trillion. Current media reports place the anticipated valuation somewhere between $1.75 trillion and $2 trillion.
The Supply-and-Demand Risk to Broader Stocks
Cramer’s deeper concern goes beyond SpaceX alone. He warned that a wave of mega-cap technology listings could pressure the wider market. Investors chasing new issues tend to liquidate existing positions to free up cash. That rotation creates selling pressure across the board. He framed the dynamic in simple terms, noting that any market breaks down when supply overwhelms demand. The worry is not that SpaceX itself is a bad business. It is that artificial scarcity of shares could sever the stock’s price from any rational fundamental anchor almost immediately.
A Pattern the Dot-Com Era Made Infamous
This is not the first time markets have wrestled with frothy IPO conditions. During the late 1990s dot-com boom, underwriters routinely engineered explosive opening pops by severely restricting float. Those pops drew in waves of speculative capital, inflated valuations broadly, and ultimately contributed to the crash that followed. Cramer explicitly invoked that period, urging today’s underwriters to resist the temptation to manufacture dramatic first-day gains.
OpenAI and Anthropic Are Watching
The stakes extend well beyond a single listing. Cramer flagged that OpenAI and Anthropic are each weighing their own public offerings. If SpaceX sets a precedent for structuring deals to maximize first-day fireworks, both companies could follow suit. A succession of trillion-dollar-plus AI listings, each engineered for maximum pop, could collectively drain liquidity from the rest of the market at a significant scale. The outcome, Cramer said, hinges almost entirely on whether underwriters choose discipline over spectacle this time around.
