SpaceX debut stirs buzz, but hot IPOs often lag market

Wall Street’s excitement over SpaceX is reviving a familiar market question: when the hype fades, do ordinary investors actually win? A review of the 50 highest-valued IPOs of the past five years found that buying an S&P 500 index fund would have beaten those stocks about three-quarters of the time, a blunt reminder that marquee listings do not always reward the public once trading begins.

The numbers are hard to ignore. Across that group of recent high-profile offerings, the IPO shares rose 27% on average through May 21, while the S&P 500 climbed 53% over the same periods. That gap matters because the hottest listings often arrive with valuations already stretched, leaving limited room for the kind of upside that early buyers hope for. The pattern suggests that scarcity, demand and branding can drive opening-day excitement, but they do not guarantee long-term outperformance.

SpaceX has become the latest test case. The company filed its prospectus on Wednesday and could begin a share sale as early as June 11 under the ticker SPCX. Retail investors are expected to get access through platforms including Robinhood and SoFi, widening the audience beyond the institutions that usually dominate large, scarce offerings. The expected June listing has drawn outsized attention because of both its symbolism and its size.

The company’s target valuation could reach $1.75 trillion, a figure that would place it among the most ambitious public debuts ever attempted. But that scale also sharpens the risk. The analysis argues that lofty price-to-sales ratios can leave little margin for error, especially when a business is still burning cash. SpaceX lost nearly $5 billion last year, a reminder that even the most celebrated growth stories can disappoint once they are priced against public market expectations.

SpaceX is also being read as part of a larger capital-markets cycle built around artificial intelligence and giant private companies with household names. The market is already looking ahead to possible listings from OpenAI and Anthropic, which would extend the same scramble for access, allocation and status. Yet the historical record points to a sobering conclusion: spectacle can create demand, but valuation discipline still determines who benefits after the debut confetti clears.
