SpaceX IPO: What UK Investors Need to Know

Is SpaceX going public?

Yes. SpaceX has formally filed with the US Securities and Exchange Commission and confirmed it intends to list on the public markets this month. After years of speculation, the question is no longer if - it's how to prepare.

The listing is expected to be the largest IPO in history, surpassing Saudi Aramco's $29 billion raise in 2019 and Alibaba's 2014 debut.

When could the SpaceX IPO happen?

SpaceX is expected to price its shares on the evening of Wednesday 11 June 2026, with trading beginning on Thursday 12 June. The Nasdaq is the frontrunner as the listing exchange.

SpaceX confidentially filed with the SEC in April 2026 and kicked off its investor roadshow on 8 June. The timeline has moved quickly — this is now a live event, not a future possibility.

What is SpaceX worth?

SpaceX has announced it intends to list at a valuation of $1.77 trillion, selling more than 555 million shares at $135 apiece and raising approximately $75 billion in fresh capital. That would make it not just the largest IPO ever by funds raised, but one of the most valuable companies on earth by market capitalisation — in the same bracket as Apple, Microsoft and Nvidia.

To put the growth in context: SpaceX raised $1.7 billion at a $125 billion valuation back in June 2022. By December 2024 it had become the most valuable private company in the world at $350 billion. The February 2026 all-stock merger with Elon Musk's AI company xAI pushed the combined private valuation to approximately $1.25 trillion — and the IPO valuation now goes beyond that.

It's also worth noting that SpaceX is exploring a dual-class share structure, similar to that used at Tesla, which would allow Musk to retain voting control after listing. This is a meaningful governance consideration for any long-term investor.

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 alongside 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 share of that.

How to buy SpaceX shares

SpaceX is listing in the US. UK investors will be able to buy shares directly through a standard share dealing account from 12 June.

With XTB, you can open an account today and be ready to invest the moment SpaceX shares go live. 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 SpaceX 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 trading going live, a small number of routes exist — though none offers the direct, concentrated exposure that a public listing provides.

• 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 directly 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 is going public on 12 June 2026. With a confirmed $1.77 trillion valuation and $75 billion raise, this is shaping up to be the largest IPO in history — and one of the most significant investment opportunities in a generation.

But extraordinary companies can still be expensive at IPO, and the risks here — regulatory, financial, governance — are real and deserve serious consideration before investing.

For UK investors, the key step right now is to be ready. Having an account in place means you won't miss the window when SpaceX shares start trading next week.
