SpaceX IPO: What UK Investors Need to Know

Is SpaceX going public?

SpaceX has long been one of the most talked-about potential IPOs in financial history, and in 2026 the speculation has become considerably more concrete. Multiple outlets including the Financial Times have pointed to mid-2026 specifically June as the likely window for a listing.

If it proceeds, SpaceX could price at a valuation of up to $1.5 trillion, potentially raising around $50 billion in a single offering. That would rank it among the largest IPOs ever recorded, comfortably exceeding the scale of Alibaba's 2014 listing.

No formal SEC filing has been made, and neither Elon Musk nor SpaceX COO Gwynne Shotwell has publicly confirmed a date. Investors should treat any reported timeline as indicative until a regulatory filing is submitted. But market signals suggest this is no longer a question of if  it's increasingly a question of when.

When could the SpaceX IPO happen?

The most widely cited window is June 2026. Some coverage has noted that this aligns with Elon Musk's birthday on 28 June, though these reports are based on unnamed sources.

Historically, Shotwell has suggested the company would not go public until it was flying regularly to Mars. The shift in tone reflects the sheer scale of capital SpaceX now requires for Starship commercialisation, orbital AI infrastructure, and deep space exploration that is making public markets an increasingly necessary step.

What is SpaceX worth?

SpaceX's valuation has risen sharply in a short time. In June 2022, the company raised $1.7 billion at a $125 billion valuation. By December 2024, Bloomberg reported it had become the most valuable private company in the world at $350 billion.

Then came the February 2026 merger with Elon Musk's artificial intelligence company xAI, in an all-stock deal. The combined private valuation was reported at approximately $1.25 trillion, with some IPO scenarios placing the listing valuation as high as $1.5 trillion.

For comparison, that would put SpaceX in the same bracket as Apple, Microsoft and Nvidia among the most valuable companies on earth by market capitalisation.

The IPO share price will depend on how shares are structured, but investors might reasonably expect a figure in the hundreds of dollars per share. SpaceX has reportedly explored dual-class share structures, similar to those used at Tesla, to allow Musk to retain voting control after a listing. This is worth weighing carefully.

What does SpaceX actually do?

SpaceX has three main business pillars: rocket launch services, the Starlink satellite broadband network, and long-term space exploration.

Launch services are the foundation. SpaceX's partially reusable Falcon 9 and Falcon Heavy rockets command between 60% and 70% of the global commercial satellite launch market. The company now completes over 135 launches per year matching in a single year the total number of missions NASA's Space Shuttle flew across its entire 30-year history. Cost reductions have been dramatic: while the Shuttle cost roughly $54,500 per kilogram to reach orbit, Falcon 9 has brought that down to approximately $2,700, with the in-development Starship targeting under $150.

Starlink is now SpaceX's primary revenue engine. As of early 2026, the satellite internet service has reached 10 million subscribers across 155 countries up from 4 million in September 2024. SpaceX generated approximately $8 billion in profit on $15–16 billion in revenue last year, with Starlink accounting for as much as 50–80% of total revenue. Deals with airlines including Air France and United Airlines add commercial B2B momentum to its direct-to-consumer subscription model.

The xAI merger adds a new dimension. The combined entity now encompasses Starlink broadband, Grok AI and related AI products, SpaceX's launch and satellite infrastructure, and indirectly the social platform X. The strategic ambition is to link AI development directly with SpaceX's orbital capabilities, including space-based AI data centres. Some analysts view this as a powerful convergence of two high-growth technology themes; others flag integration complexity and the cash burn associated with AI development.

The global space economy is projected to reach $1.8 trillion by 2035. SpaceX is well positioned to capture a significant portion of that.

How to buy SpaceX shares

If SpaceX proceeds with a US listing, UK investors will be able to buy shares directly through a standard share dealing account.

With XTB, you can open an account today and be ready to invest the moment SpaceX shares become available. When dealing in shares, you own the stock outright and become a shareholder. You'll profit if the share price rises above the level at which you bought, or from any dividends paid.

It's worth noting that you could get back less than you invest.

For investors with a higher risk appetite, leveraged products such as CFDs allow you to trade the SpaceX IPO without owning shares outright, these are leveraged instruments that carry a high risk of losing money rapidly and require careful risk management.

How to get SpaceX exposure before the IPO

For investors who want some degree of SpaceX exposure ahead of any listing, a small number of routes exist though none offers the direct, concentrated exposure that a public listing would provide.

• ERShares Private-Public Crossover ETF (XOVR) lists SpaceX as its top holding, with a 0.75% expense ratio.
• Edinburgh Worldwide Investment Trust (EWI) also counts SpaceX as a leading position and is traded on the London Stock Exchange, making it accessible to UK investors.
• Rocket Lab (RKLB) is a Nasdaq-listed company competing in the small satellite launch market, a higher-risk, higher-conviction bet on the same industry dynamics.
• Broader aerospace and defence exposure can be found through established names like Lockheed Martin and Boeing, though these are far removed from SpaceX's growth profile.

These are imperfect proxies. They can move independently of SpaceX's own fortunes and carry their own distinct risk profiles.

What are the risks of investing in SpaceX?

Even the most compelling investment cases carry risks, and SpaceX's are worth spelling out clearly.

Capital requirements are enormous. Developing Starship to full commercial operations, expanding Starlink to global coverage, building out space-based AI infrastructure, and eventually funding Mars missions will require sustained, large-scale investment for years to come.

The xAI merger adds complexity. Integrating an AI business with significant cash burn into SpaceX's balance sheet creates financial risks that would not otherwise exist. The inclusion of X within the corporate structure adds governance questions that are unusual for an aerospace company.

Regulatory exposure is real. The US government is SpaceX's largest customer, and the relationship between Musk and political institutions is subject to change. Going public also brings disclosure obligations that could constrain the company's ability to operate with its current speed and secrecy.

IPO volatility is a consistent pattern. Early trading on high-profile listings is frequently volatile, and valuations at launch can reflect hype as much as fundamentals. The gap between a company's story and its financial reality often narrows under public market scrutiny.

Environmental and ethical concerns are also worth noting. These include rocket emissions in the upper atmosphere, biodiversity risks around launch sites, the impact of Starlink satellites on astronomical observation, and broader questions about the concentration of space infrastructure in private hands.

None of these are necessarily reasons to avoid a SpaceX investment, but they are material considerations for any investor thinking about long-term risk.

The bottom line

SpaceX represents one of the most extraordinary commercial stories in modern business and potentially one of the most significant investment opportunities of the decade. Its dominance in launch services, the rapid growth of Starlink, and the scale of its long-term ambitions are genuinely remarkable.

But remarkable companies can still be overpriced at IPO, and the risks here, regulatory, financial, governance are real and worth taking seriously.

For UK investors, the key step right now is to be prepared. Having an account in place means you won't miss the window when SpaceX shares do become available.
