Before you invest in SpaceX: the IPO details most investors are missing

June 4, 2026

Elon Musk’s SpaceX is days away from what could become the largest initial public offering in history, giving the public its first opportunity to own shares in the rocket, satellite, and artificial intelligence company.

The company has now disclosed its IPO price, launch timeline, and other details, answering some of the biggest questions investors have been asking, including when is the SpaceX IPO and whether the company justifies its enormous valuation.

For investors looking to invest in SpaceX, here are the key details to understand before the shares begin trading.

SpaceX IPO price set at $135 per share

The company revealed in an updated filing with the Securities and Exchange Commission that the SpaceX IPO price has been fixed at $135 per share.

SpaceX plans to sell 555.6 million shares, which would raise approximately $75 billion.

Underwriters also have the option to purchase an additional 83.33 million shares worth roughly $11.2 billion.

At the proposed SpaceX IPO price, the company would be valued at approximately $1.77 trillion, making it one of the most valuable publicly traded companies in the United States from day one. 

The valuation would place SpaceX ahead of Tesla and rank it among the country’s largest listed firms by market capitalisation.

The decision to publish a fixed price before the official roadshow is unusual for a major US IPO. 

Most companies provide a pricing range and adjust based on investor demand. 

SpaceX instead opted to set a price ahead of formal marketing efforts following months of discussions with potential investors.

When is the SpaceX IPO?

One of the most searched questions among prospective investors is when is the SpaceX IPO.

The company is expected to begin its investor roadshow ahead of the weekend. 

Final pricing is anticipated on June 11, with shares expected to begin trading on the Nasdaq on June 12 under the ticker symbol SPCX.

That timeline means investors have only a short window to review the company’s financials and determine whether they want exposure to the stock before trading begins.

The roadshow will likely provide additional clues about institutional demand and whether investors are comfortable supporting one of the largest valuations ever assigned to a newly public company.

What the SpaceX IPO prospectus reveals

The SpaceX IPO prospectus offers the most detailed look yet at the company’s finances and structure.

The filing confirmed that Elon Musk will retain substantial control after the offering, with more than 82% voting control through the company’s share structure.

It also revealed the extent of SpaceX’s integration with Musk’s other businesses. 

The filing noted that xAI purchased $269 million worth of Tesla Megapacks in April, while Tesla itself owns nearly 19 million SpaceX shares that would be worth roughly $2.56 billion at the IPO price.

The SpaceX IPO prospectus also highlighted the company’s strategy of combining space technology, satellite communications, and artificial intelligence under a single corporate umbrella. 

However, it indicated that AI-related operations continue to generate significant losses as the company invests heavily in computing infrastructure.

Is SpaceX a good investment?

The question of whether SpaceX is a good investment largely depends on how investors assess the company’s valuation and future growth prospects.

Supporters point to SpaceX’s dominant position in commercial space launches, the continued expansion of Starlink, and the company’s ambitions in artificial intelligence. 

Few businesses can claim leadership positions across multiple high-growth industries simultaneously.

The company also benefits from Musk’s track record of building transformative businesses and attracting investor enthusiasm.

However, critics argue that the current valuation already assumes years of future success. 

Research firm Morningstar recently estimated SpaceX’s fair value at approximately $780 billion, significantly below the company’s targeted valuation of roughly $1.75 trillion.

That creates a valuation gap of nearly $970 billion.

Morningstar analyst Nicolas Owens said the company appears “significantly overvalued” and suggested investors may find more attractive entry points after the IPO.

The debate highlights an important distinction: a strong company does not automatically translate into an attractive investment if investors pay too high a price.

What should investors watch next?

For anyone planning to invest in SpaceX, the next several days could prove crucial.

The investor roadshow will offer the first indication of whether institutional investors are willing to support the company’s valuation. 

Market conditions, investor demand, and management’s ability to justify future growth assumptions may all influence how the stock performs once trading begins.

With the SpaceX IPO price set at $135 per share and trading expected to begin on June 12, attention will now shift to roadshow feedback, final allocations, and opening-day demand.

Before deciding to invest in SpaceX, investors should carefully review the SpaceX IPO prospectus and evaluate the company’s financials.
