SpaceX Stock Falls as Valuation Concerns and Insider Selling Risks Grow

Space Exploration Technologies Corp. stock fell sharply during morning trading, as investors reacted to valuation concerns, competitive threats, and a broader technology-sector sell-off.

SpaceX shares dropped nearly 4.8% to around $138.35. The stock moved closer to its $135 IPO price and 52-week low after opening the session at $144.51.

Several negative developments contributed to the decline, including a harsh valuation warning, concerns about future insider selling, and weaker sentiment toward high-growth technology stocks.

Investor Warns of a Major SpaceX Valuation Bubble

One of the main pressures on SpaceX stock came from comments made by veteran investor George Noble.

In a public post, Noble described SpaceX as the most extreme large-cap valuation bubble he had encountered during his career.

He estimated that the company’s fair value could be as low as $30 per share. That figure stands far below the current market price.

His comments intensified concerns that SpaceX stock may be trading at a valuation that is difficult to justify through current financial results.

China’s Rocket Progress Raises Competition Concerns

Competitive pressure also weighed on investor confidence.

Morgan Stanley highlighted China’s successful recovery of the Long March 10B orbital-class rocket booster as a major long-term risk to SpaceX.

The achievement reportedly made China only the third entity, after SpaceX and Blue Origin, to recover this type of booster.

Reusable rocket technology has been one of SpaceX’s strongest advantages. Therefore, further progress from China could eventually challenge the company’s position in the global launch market.

Bernstein Maintains a Bullish SpaceX Price Target

Despite the negative sentiment, SpaceX received some support from Bernstein SocGen.

The firm maintained its Outperform rating and repeated its $239 price target.

However, the positive analyst view was not enough to offset broader concerns surrounding valuation, competition, and the potential increase in tradable shares.

Insider Lockup Expiration Could Increase Share Supply

Investors are also preparing for the first major expiration of insider lockup restrictions.

The first important selling window is expected to open around SpaceX’s second-quarter earnings report in late July.

Approximately 20% of currently locked shares could become eligible for trading. This could more than double the existing public float.

A significant rise in available shares may create additional selling pressure, especially if early investors and insiders decide to take profits.

FAA Clears SpaceX for Another Starship Test

SpaceX received positive regulatory news after the Federal Aviation Administration completed its investigation into a May Starship booster return failure.

The conclusion of the investigation could allow SpaceX to conduct its next Starship test flight as early as this week.

However, the development failed to provide enough support to reverse the decline in SpaceX shares.

Investors appeared more focused on valuation risks and the broader weakness affecting technology stocks.

Global Technology Sell-Off Hits Growth Stocks

The wider market environment also contributed to the fall in SpaceX stock.

A global semiconductor sell-off began in Asia after SK Hynix recorded its largest one-day share-price decline.

The drop pushed South Korea’s Kospi index sharply lower and spread across European and U.S. chip companies.

This created a risk-off environment that placed additional pressure on high-valuation technology and growth stocks.

US–Iran Tensions Add to Market Uncertainty

Escalating military tensions between the United States and Iran further weakened investor appetite for risk.

Reports included attacks on Iranian targets, Iranian missile responses, and the possible closure of the Strait of Hormuz.

These developments encouraged investors to reduce exposure to more volatile growth assets.

The Nasdaq fell by around 0.9%, while the S&P 500 declined approximately 0.2%. The Dow Jones remained slightly positive, showing that most of the selling was concentrated in technology stocks.

Why SpaceX Stock Is Falling Today

The decline in SpaceX stock reflects several pressures occurring at the same time.

George Noble’s severe valuation warning increased doubts about the company’s current share price. China’s rocket recovery milestone raised concerns about future competition, while the upcoming insider lockup expiration created fears of additional share supply.

At the same time, a global technology sell-off and rising geopolitical risks reduced demand for high-growth equities.

SpaceX shares are now trading only slightly above the $135 IPO price. This represents a sharp reversal from the post-IPO high of $225.64 reached less than one month ago.
