SpaceX Stock Falls 4% as August 6 Lock-Up Expiration Looms

SpaceX shares (NASDAQ: SPCX) extended their post-IPO decline on Monday, falling 4.0% to $113.50 as investors positioned defensively ahead of a pivotal date on the calendar: August 6, 2026, when the company's initial share lock-up expires and a wave of insider supply is set to hit a market that has absorbed the stock poorly since its June debut.

The lock-up expiration is expected to release up to 911.5 million shares, a figure that exceeds the current public float, which represents just 4-5% of SpaceX's total share count, according to Benzinga. The potential influx of supply has amplified selling pressure in the days leading up to the date, a pattern common with high-profile IPOs that carry a large insider shareholder base.

Stock still 16% below IPO price

SpaceX priced its IPO at $135 per share on June 11, 2026, listing on the Nasdaq on June 12 at a valuation of approximately $1.77 trillion. After a brief post-IPO surge above $160, the shares have retreated steadily. At today's close of $113.50, SPCX is 16% below the offer price and has shed roughly 25.8% over the past month.

The implied market capitalization at the current price is approximately $1.49 trillion, down from the $1.77 trillion IPO valuation, representing a contraction of roughly $280 billion in market cap since the June offering.

Analyst consensus remains bullish

Despite the price decline, Wall Street analyst sentiment on SPCX remains strongly positive. Twenty-seven of 28 analysts covering the stock rate it a Buy, with an average 12-month price target of $236.71, according to Yahoo Finance. The consensus target implies upside of more than 100% from the current price if achieved.

The wide range of targets reflects deep disagreement on valuation methodology. Morningstar places fair value near $780 billion, below even the current market cap, while ARK Invest sees the stock reaching a valuation of up to $3.1 trillion by 2030 on the strength of its Starlink satellite-internet business. The short-run supply dynamics of the August 6 lock-up expiration are separate from these long-term views.

What to watch on and after August 6

The August 6 expiration does not guarantee that all 911.5 million newly eligible shares will be sold. Executives and institutional holders typically stagger sales to avoid disrupting the market, and large selling programs are often conducted through scheduled 10b5-1 plans filed in advance. However, the sheer size of the potential supply relative to current float means even modest selling activity could have an outsized effect on price.

Traders will be watching daily volume and short interest in the days immediately following the expiration for signs of whether insider selling is materializing at scale. Any company or executive statements about planned share sales, or the absence of them, could move the stock materially.
