SpaceX stock has only moved one direction since its IPO last week - up. That run just ended on Nasdaq, where shares fell for the first time since the company went public, snapping a three-day rally that had briefly pushed SpaceX past Amazon and even ahead of Microsoft by market cap.
The drop was sharp - SPCX closed down about 5% on Wednesday, June 17. And the timing makes it worth a closer look, because insiders aren't even allowed to sell yet.

A Public Stock With Almost No Float
SpaceX listed on Nasdaq on June 12 under the ticker SPCX, pricing its IPO at $135 a share and raising about $75 billion - the largest public offering in stock market history.
The catch: SpaceX only floated about 4-5% of its shares. The vast majority sit in insider hands, locked up under the IPO agreement, which is part of why the price ran so hot out of the gate.
That tight float helped push SpaceX above a $2 trillion valuation in its first three sessions, briefly making it the fifth-most-valuable U.S. stock as it leapfrogged Amazon and touched Microsoft.
The setup worked because retail demand was relentless - individual investors bought more SPCX than any other stock every single day since the offering. That makes a price drop in this market notable on its own - and a drop before the lockup expires is something else entirely.
Why The Lockup Timing Matters
A lockup is the period after an IPO when insiders and early backers are blocked from selling their shares. It keeps employees from rushing for the exits the moment shares start trading.
When a stock falls after a lockup ends, the story is simple - insiders sold, supply went up, and the price went down.
When a stock falls before the lockup ends, the story changes. It means outside buyers are pulling back on their own, without any new shares hitting the market.
That's a demand problem, not a supply one. And for a stock that's only known rising prices, a demand wobble is the more telling signal.
It also matters that the drop landed one day after SPCX options began trading - giving bears their first practical way to bet against the stock.
What To Watch
The drop trimmed gains but didn't erase them - SPCX still sits roughly 42% above its $135 IPO price.
SpaceX's lockup is staggered, not a single 180-day wall. Insiders can sell up to 20% of their holdings after the Q2 earnings report, expected in late July or August. An extra 10% unlocks only if the stock closes at or above $175.50 - 30% above the IPO price - on at least 5 of the 10 trading days leading into that report.
If prices keep slipping before insiders even get a chance to sell, that first unlock window becomes the real test.
The public market just pushed back for the first time, and the bigger test comes when the lockup actually lifts. That's when investors will see whether the demand wobble was a one-time blip or the start of something bigger.
