Elon Musk’s SpaceX is preparing to launch the largest initial public offering (IPO) in stock market history on 12th June 2026, aiming for a staggering $1.77 trillion (£1.39 trillion) valuation. The highly anticipated stock market debut has been heavily oversubscribed, driven by immense investor excitement surrounding the company’s Starlink satellite network and its ambitious artificial intelligence integration. However, while the headlines focus on astronomical valuations and the prospect of Musk becoming the world's first trillionaire, the reality of investing in a loss-making aerospace business carries significant risks. For UK investors considering buying a stake in the space race, it is important to look past the hype and understand exactly what a SpaceX investment entails.
In this article, we explain 7 things you need to know about the SpaceX IPO, including when it launches, how you can invest and the potential risks.
1. When will the SpaceX IPO launch
According to the company's latest stock market filings, SpaceX shares are expected to begin trading on the US Nasdaq exchange on 12th June 2026. The company has priced its shares at $135 each, intending to raise up to $75 billion. If successful, this will comfortably surpass the 2019 Saudi Aramco IPO to become the largest stock market debut of all time, instantly making SpaceX one of the ten most valuable companies in the world.
2. Is SpaceX a profitable company?
The excitement surrounding the IPO is not just about reusable rockets or colonising Mars; much of the $1.77 trillion valuation is tied to artificial intelligence and global connectivity through its Starlink division. However, it is important to understand that SpaceX is not currently a profitable company. While Starlink generates significant revenue, the broader business is burning through cash to fund its ambitious projects, reporting a $4.9 billion net loss in 2025. Furthermore, SpaceX is aiming to list at a price that values the business at around 92 times its 2025 revenue - a far higher premium than established tech giants. Additionally, retail investors will have zero voting power, as Elon Musk will retain over 82% of the voting control.
3. How UK retail investors can access the SpaceX IPO
Historically, major US IPOs have been locked off to everyday UK retail investors until the shares officially hit the open market. However, SpaceX has explicitly carved out a retail allocation, meaning everyday investors can apply for shares before the opening bell. Because UK platforms are offering access via public offer platforms (POPs), investors can buy into the IPO directly through their existing Stocks and Shares ISA or Self-Invested Personal Pension (SIPP). While the stock officially begins trading on 12th June, many UK platforms offering early access have set a strict application cutoff of midnight on 10th June 2026. This deadline is required to allow brokers to collate orders, process the currency exchanges, and submit the final block of retail demand to the US underwriters. Missing this cutoff means you will likely have to wait until the shares are trading on the open market, where the price may be significantly higher or lower.
4. Which UK investment platforms are participating?
Several major UK investment platforms have confirmed they will allow customers to participate in the SpaceX IPO. Freetrade, AJ Bell, interactive investor, Hargreaves Lansdown, and Trading 212 are all providing avenues for UK consumers to gain exposure. The way each platform manages allocation varies: some offer early applications before the 10th June cutoff, while others are simply preparing to offer the stock for standard trading on the 12th June launch day.
5. Is there a minimum investment?
There is no set minimum investment requirement, with a number of UK platforms announcing different entry requirements. Hargreaves Lansdown, for example, requires a minimum investment of £1,000 to apply for the IPO, while Freetrade has sent invitations to its users with a lower minimum investment threshold of £500. Trading 212, meanwhile, has confirmed that SpaceX shares will be available to purchase on the app on the IPO date (12th June), meaning standard fractional investing rules will apply once the market opens, allowing investments from as little as £1.
6. What are the risks?
When a company goes public, early investors and company insiders are usually subject to a "lock-up period" - a timeframe during which they cannot sell their shares. Once this period expires, a flood of new shares can enter the market as early backers take their profits. This sudden increase in supply can cause the share price to drop significantly. UK investors buying in at the IPO stage must be prepared for this potential volatility in the days, weeks or even months following the launch.
It is easy to get swept up in the media frenzy surrounding a high-profile launch like SpaceX, but IPOs are notoriously volatile. Companies often debut at peak valuations, and it is not uncommon for share prices to dip below their initial offering price in the weeks that follow. Investing in individual shares should never make up more than a small part of a widely diversified portfolio. If you cannot afford to lose the money you are investing, or if you are relying on a quick profit, participating in a mega-cap IPO is a highly risky strategy.
While a $1.77 trillion valuation sounds impressive, even if the share price were to surge by 20% on its first day of trading (a common, but not guaranteed, IPO "pop"), your £1,000 investment would yield a paper profit of around £200. Conversely, if the stock drops 20% due to overvaluation fears, your initial stake immediately shrinks to £800.
To understand what your money actually gets you, it helps to calculate the real-world impact. Hargreaves Lansdown requires a minimum investment of £1,000. Assuming an exchange rate of roughly £1 to $1.27, your £1,000 equates to around $1,270. With SpaceX pricing its IPO shares at $135 each, a £1,000 investment would secure you just 9 full shares (leaving a small cash remainder).
7. Alternative ways to gain indirect exposure to SpaceX
If buying directly into a highly volatile IPO feels too risky, investors can already gain indirect exposure to SpaceX through existing UK investment trusts that hold private shares in the company. For example, Baillie Gifford US Growth Trust PLC currently has 14.89% of its assets invested in SpaceX shares, while Baillie Gifford Edinburgh Worldwide IT PLC has a 16.23% exposure. To put this into real terms, if an investor were to invest £1,000 into the Edinburgh Worldwide IT PLC trust, approximately £162.30 of their capital would be indirectly invested in SpaceX. This strategy allows an investor to invest in the company's growth as part of a professionally managed, diversified portfolio.
When investing, your capital is at risk and you may get back less than invested. Past performance doesn’t guarantee future results.
