On June 12, Elon Musk’s Space Exploration Technologies (SPCX -2.80%), better known as SpaceX, rewrote Wall Street’s record books. The $85.7 billion raised from its initial public offering (IPO), including the underwriters’ overallotment, was nearly three times that of the previous record holder, Saudi Aramco. SpaceX’s $1.77 trillion initial valuation was also the largest in history, though Anthropic could soon surpass it.
Musk’s artificial intelligence (AI) and space infrastructure goliath sports a self-proclaimed $28.5 trillion addressable market, much of which ties to its AI ambitions. This lofty figure, coupled with Musk’s success in growing Tesla (TSLA -2.15%) into a trillion-dollar business, has retail investors excited.

But not all of SpaceX’s history-making moments are of the desirable variety. In a little over one week, it’s set to make dubious history yet again, with retail investors likely to pay the price.
Yet another accelerated insider share-unlock event is coming
When private companies go public, they typically implement a 180-day lockup period for insiders. An “insider” is a high-ranking executive, board member, or beneficial owner holding at least 10% of a company’s outstanding shares.
Public companies put these lockup periods into place to prohibit insiders from taking advantage of retail investor euphoria shortly after a company’s IPO.
SpaceX ignored convention by unveiling a staggered and accelerated share-unlock schedule for its insiders in its mile-long prospectus.
Great look at the SpaceX shares unlock schedule as well as the potential passive buying schedule from @JSeyff @FrancisSharoon Depending on the early post-IPO returns, this could really play with and disperse the returns of “passive” funds (which is why there’s arguably no such thing as passive). $SPCX

The good news for retail investors is that Elon Musk, who holds a majority of SpaceX’s outstanding shares, isn’t eligible to sell any shares for 366 calendar days after his company’s debut. But it’s a completely different story for early-release-eligible insiders.
On the second day after SpaceX’s first quarterly report as a public company, approximately 911.5 million shares became eligible for sale by insiders. The same number of shares will be eligible for sale two trading days after SpaceX’s next quarterly report.
Additionally, several time-based events allow eligible insiders to sell some of their shares. These events occur on calendar days 70, 90, 105, 120, 135, and 180. Given that calendar day 135 lands on a weekend, Oct. 26 will unlock another 319 million early-release-eligible insider shares for sale.

We’re witnessing the greatest wealth transfer in history
Unfortunately, this staggered and accelerated share-unlock schedule is only part of the story. Space Exploration Technologies’ historically low float is also concerning for retail investors.
When companies go public, they traditionally sell anywhere from 10% to 25% of their outstanding shares. Though Musk’s SpaceX offered approximately 555.6 million shares at its IPO, which sounds like a lot, it amounts to less than 5% of its outstanding shares.
The advantage of offering fewer shares for its IPO was observed shortly after its debut. Fast-track entry for SpaceX into the Nasdaq-100, Russell 1000, and Russell 3000 meant that passive funds were gobbling up the company’s shares and bolstering its share price.

The downside is that every subsequent share-unlock event risks drowning retail investors in a rapidly growing float. While not every early-release-eligible insider is selling their shares, many of these individuals have had no avenues to lock in their gains for years.
In other words, we’re witnessing one of the greatest wealth transfers in Wall Street’s history. Unfortunately, it’s from retail investors to SpaceX’s insiders and not the other way around.
