Wall Street’s relationship with high-growth companies has evolved significantly over the past few decades, as evidenced by the recent trajectory of SpaceX. Founded by Elon Musk approximately 24 years ago, SpaceX is now preparing for a public listing, highlighting a notable shift towards private market growth that has left public investors grappling for entry points.
Historically, Wall Street would get early access to the growth stories of emerging tech companies. However, this pattern has changed, leading to a landscape where public investors often feel like they’re receiving the “receipt” for a growth journey that has already largely unfolded in private markets.
A comparative analysis of the largest IPOs over the last forty years showcases SpaceX’s delayed entry into the public market. For instance, companies like Amazon and Apple went public just a few years after their founding, with Amazon listing roughly three years after its inception and Apple taking about five. Other successful public firms such as Alphabet and Nvidia took around six years to hit the market.
In contrast, more recent companies have opted for longer timelines before their IPOs. Tesla waited about seven years, while Meta followed with a timeline of approximately eight years. Companies like Coinbase, Uber, and Spotify pushed the boundaries even further, waiting closer to a decade or more. Palantir and Reddit extended the trend, with waiting periods of 17 and 19 years, respectively.
SpaceX’s anticipated timeline for going public suggests an even longer duration in private markets, positioning it near the outer limits of this trend. This trend is underscored by the observation that while IPOs were once seen as the beginning of a company’s journey, they are increasingly viewed as a liquidity event for early investors, employees, and backers, allowing them to cash out after years of value creation in the private sector.
The trend is not uniform, as notable exceptions exist. For instance, Arm recently made its debut on the Nasdaq after a prior public existence ended with SoftBank taking the firm private in 2016. Likewise, Saudi Aramco’s listing reflects a complex history, as it was created in 1988 but did not go public until 2019.
In summary, the impending SpaceX IPO symbolizes a significant shift in how tech companies navigate their growth and public offerings, raising questions about the implications for future investors and the nature of public markets moving forward.
