SpaceX IPO Becomes Largest in History Amid Skepticism from Market Veteran Jeremy Grantham

SpaceX made its initial public offering (IPO) debut on June 12, with shares beginning trading at $150, above the listing price of $135 per share. As of midday Wednesday, the stock was trading around $149 per share and was down nearly 7% month-to-date [1]. The IPO raised $75 billion, making it the largest IPO in history and surpassing Saudi Aramco's $29 billion IPO in 2019 [1]. This event also solidified Elon Musk's position as the world's richest person, with the value of his holdings approaching $1 trillion, a milestone no individual has previously reached [1].

SpaceX was fast-tracked into the Nasdaq-100 Index, directly tying its stock performance to the retirement accounts, mutual funds, and portfolios of millions of everyday American investors [1]. Market "permabear" and GMO co-founder Jeremy Grantham expressed heavy skepticism about SpaceX's valuation and long-term investment thesis. Grantham stated, "Everyone’s lining up to tell you to buy the craziest IPO in the history of man," and predicted that in 50 years, people would look back and laugh at SpaceX's IPO prospectus [1]. He further warned that the company's success would require massive developments in AI, fundamentally changing society, and suggested that the current market demand, driven by index inclusion, could push the price up further in the short term [1].

Despite Grantham's skepticism, major Wall Street firms such as Goldman Sachs, JPMorgan, and Morgan Stanley have issued bullish forecasts for SpaceX, with price targets ranging from $205 to $300 per share, according to Fortune [1]. Grantham also criticized Wall Street's advice for clients to buy SpaceX, cautioning that even if the market validates the elevated share price, it could lead to a society dominated by automation [1].

SpaceX, founded by Elon Musk in 2002, has become the world's largest space company and a dominant force in commercial launch services. The company pioneered reusable rocket technology, lowering launch costs and reshaping the economics of the space industry. It is also a key contractor for NASA and the U.S. government for civil and national security missions [1].

CONCLUSION

SpaceX's record-breaking IPO has generated significant market attention, with bullish forecasts from major banks but strong skepticism from veteran investor Jeremy Grantham. The company's rapid inclusion in the Nasdaq-100 and its impact on index funds highlight its broad market influence. Investors face a polarized outlook, with both high expectations and cautionary warnings shaping the narrative.
