Yahoo Finance says SpaceX faces a major December share unlock

SpaceX’s unusually small float at IPO

Yahoo Finance reports that when Space Exploration Technologies, trading under NASDAQ: SPCX, went public this summer, it broke from a common IPO pattern by offering only 5% of its outstanding shares to the public. The article says many large tech companies have historically sold 15% to 20% of shares at listing, and it notes that offering such a small float is not inherently wrong, but it can create complications.

Index access and volatility concerns

According to Yahoo Finance, the S&P 500 generally requires a public float of at least 10%, and SpaceX’s request for fast-track inclusion was denied. The article also says a low float can make prices more volatile because trading surges can overwhelm the shares available. It adds that, while other factors were involved, the limited float likely contributed to SpaceX’s early stock swings.

Earlier unlocks before December

Yahoo Finance says there is precedent for very small IPO floats, citing Saudi Aramco, which raised $25.6 billion with a 1.5% initial public float. SpaceX, by contrast, raised $85.7 billion without lifting its float above 5% at the offering. The article says the float then expanded quickly: another 20% of shares became tradable after second-quarter earnings in August, and October’s third-quarter results released another 28%. It says additional unlock events happened in the surrounding months, and another 17% will become available in December.

What happened in October

The article says those earlier releases left only one major block still locked, aside from a large tranche tied to CEO Elon Musk that is due to unlock next summer and is unlikely to be sold. Yahoo Finance says analysts had worried that successive unlocks could create selling pressure. It reports that SpaceX already saw the biggest share unlock in history in October, when more than $180 billion of stock became available.

Trading reaction and the December question

Yahoo Finance says the stock became volatile in early October, rising from $150 to $170 before giving back those gains by the time earnings were reported on Oct. 21. The article says 1.3 billion shares were unlocked on Oct. 22, and that heavy supply pressure led to a 9% drop that day. By the end of October, Yahoo Finance reports, SpaceX shares had fallen below the company’s IPO price. The article frames December’s 17% unlock as the next major test, and says history suggests the market has already shown how such events can affect the stock.
