SpaceX Lock-Up Expiry Selling Pressure Fails to Materialize, Short Covering Drives Consecutive Stock Gains
Claire Weston
SpaceX's first lock-up expiry freed roughly 912 million shares worth ~$100 billion, yet the expected wave of selling never came — short covering instead pushed the stock up over 14% in two days, even as it remains nearly half off its all-time high ahead of an August 20 second unlock.
What is a lock-up expiry, and why was the market bracing for it?
A lock-up is the period after an IPO during which insiders — early investors and employees — are barred from selling their shares. When it expires, those shares suddenly become tradeable.
This first tranche unlocked roughly 912 million shares, representing potential supply worth about $100 billion.
This means → the fear was straightforward: if insiders rushed to cash out at once, the resulting flood of sell orders could crater the stock.
The sell-off never came — what happened instead?
On expiry day (August 6), SpaceX rose 6.1% on volume exceeding 255 million shares — roughly four times the prior 10-day average.
In plain terms = the market was positioned for a deluge of selling. The deluge didn't show up, and the setup flipped into a scramble to buy.
SpaceX simultaneously announced plans to build an AI chip manufacturing plant in Texas, a headline that partially offset the psychological overhang of the unlock.
How did short covering become the engine of the rally?
Some short sellers — traders who borrow and sell shares, betting the price will fall — were not betting against SpaceX's fundamentals. They were specifically targeting the expected post-lock-up selling wave.
Actual selling fell far short of expectations. The trade thesis collapsed, forcing shorts to buy back shares to close their positions — that is a short squeeze.
This means → short covering is itself buying pressure. Layered on top of existing long interest, it created a self-reinforcing loop — the stock climbed over 14% across two sessions.
After a 14% rally, where does the stock actually stand?
Even after two days of gains, SpaceX closed at $124.46 — still about 15% below its $135 IPO price.
From its intraday all-time high of $225.64 on June 16, the stock is down roughly 49% — nearly cut in half.
This reflects a bounce that looks more like a technical snapback plus short covering than a fundamental re-rating.
Why is August 20 the next date to watch?
This expiry was only the first in a series of scheduled lock-up releases following SpaceX's IPO. The next major tranche is expected on August 20.
In plain terms = the market absorbed wave one, but wave two is right behind it. If that tranche is also digested, it signals genuine buying conviction; if not, the past two days' gains could unwind quickly.
Short-covering rallies are inherently temporary — once the shorts finish closing, the fuel is gone, and the stock reverts to a real supply-and-demand contest.
