SpaceX's Fleecing of Retail Investors Continues: Up to $51 Billion in Insider Shares Unlock Today, Oct. 9

Nearly four months ago, on June 12, Elon Musk's Space Exploration Technologies (NASDAQ:SPCX), better known as SpaceX, rewrote Wall Street's history books. The $85.7 billion raised from its initial public offering (IPO), including the underwriters' overallotment, and its $1.77 trillion valuation, both blew away the former record holders.

But SpaceX is also rewriting history in other, less desirable ways. Its unconventional share lockup period, coupled with a historically low float, has created a perfect storm for fleecing retail investors.

SpaceX's accelerated lockup schedule can weigh on retail investors

Normally, when a private company goes public, it prevents its insiders -- high-ranking executives, board members, and early investors, all of whom may possess non-public information -- from selling shares for the first 180 calendar days. This ensures that insiders can't take advantage of retail investor hype after a company debuts.

Musk's SpaceX ignored convention and outlined a staggered and accelerated share-unlock period for some of its insiders in its mile-long prospectus. Although CEO Elon Musk, who holds a majority of SpaceX's outstanding shares, can't sell any of his shares for 366 calendar days, a long list of early-release-eligible insiders can.

Beginning two calendar days after the company's first quarterly report as a public company on Aug. 4, 20% of early-release-eligible insider shares, about 911.5 million, became available for sale. This event has been followed by several time-based share-unlock events on calendar days 70 (Aug. 20), 90 (Sept. 9), and 105 (Sept. 24), with additional insider unlocks occurring on calendar days 120, 135, and 180.

Today, Oct. 9, marks calendar day 120. Approximately 319 million early-release-eligible insider shares can be sold, starting today, totaling nearly $51 billion in market value. While this doesn't guarantee they'll be sold, early investors haven't had any avenues to cash in their chips for years, if not a full decade... until now.

A historically low float is making things worse

But it's not just SpaceX's unconventional share-unlock period that threatens to fleece retail investors. The company's low float (i.e., tradable shares) has also played a role.

When a company goes public, it traditionally sells between 10% and 25% of its outstanding shares (OS). In the days leading up to its record-setting IPO, Space Exploration Technologies priced roughly 555.6 million shares at $135 each. While this might sound like a lot of shares, it represented less than 5% of the company's OS.

What made this low-float situation so unique was that several committees overseeing major indexes -- the Nasdaq-100, Russell 1000, and Russell 3000 -- rewrote their inclusion rules to grant SpaceX fast-track entry. This meant that passive funds scooped up a substantial number of shares shortly after SpaceX's debut, buoying its share price.

With each new early-release-eligible share-unlock period, SpaceX's float leaps higher, putting additional downside pressure on the company's shares and retail investors.

What we're effectively witnessing is one of the greatest wealth transfers in history -- except it's from retail investors to insiders and not the other way around.
