What Happened to Jim Cramer's SpaceX IPO Warning?

Jim Cramer, the outspoken host of CNBC's 'Mad Money,' issued several warnings leading up to the highly anticipated Initial Public Offering (IPO) of Elon Musk's SpaceX. His primary concerns, voiced throughout May and early June 2026, centered on the potential for speculative frenzy, an unsustainable valuation, and a detrimental impact on the broader stock market.

Cramer argued that the immense hype surrounding SpaceX, coupled with a potentially small percentage of shares made available to the public (the 'float'), could artificially inflate the stock's price far beyond its fundamental value. He suggested that scarcity-driven bidding could push SpaceX's valuation to as high as $5-6 trillion shortly after its debut. He also expressed worry that such a mega-IPO could divert significant capital from other established stocks, leading to downward pressure on the wider market, describing it as 'destructive.' Furthermore, Cramer highlighted the company's financial performance, noting a net loss of $4.9 billion in 2025 despite $18.7 billion in revenue, making the projected $1.75 trillion valuation difficult to justify purely on numbers.

Despite Cramer's cautions, SpaceX proceeded with its IPO on June 12, 2026, listing on Nasdaq under the ticker SPCX. The company priced its shares at $135 each, aiming to raise approximately $75 billion. This offering valued SpaceX at an astounding $1.77 trillion to $1.78 trillion, officially making it the largest IPO in stock market history, surpassing Saudi Aramco's 2019 debut. Investor demand reportedly exceeded $250 billion, making the deal significantly oversubscribed.

Key turning points leading to the IPO included SpaceX's confidential S-1 filing with the SEC on April 1, 2026, followed by a public filing on May 20, 2026. The company also executed a 5-for-1 stock split on May 4, 2026, to adjust per-share figures. A significant development was the acquisition of Elon Musk's AI startup, xAI, by SpaceX in February 2026, integrating AI capabilities and the social media platform X (formerly Twitter) into the broader SpaceX entity. This diversification, while adding to the company's scope, also contributed to its 2025 net loss, as the xAI division was a significant money pit.

As of June 12, 2026, SpaceX's IPO is a reality, with shares beginning to trade. The consequences of this massive debut are still unfolding. Cramer's warnings about potential volatility from short-term traders and the market's ability to absorb such a large offering remain relevant. Senator Elizabeth Warren also raised concerns about the valuation, governance structure (where Elon Musk retains significant control with 85.1% voting power), and investor protections, even requesting a delay in the IPO. The company's inclusion in major indices like the S&P 500 is not immediate due to specific eligibility rules, which could impact passive investment flows. The success of this historic IPO will be closely watched as a bellwether for future mega-tech and AI public offerings.
