You want to buy a slice of Elon Musk's giant rocket company. It makes total sense. SpaceX is literally preparing for its massive stock market debut right now on June 12, 2026, aiming for a staggering $1.78 trillion valuation.
But if you live in the UK, your retail investment platform probably just told you that you can't buy shares at launch. Platforms like Fidelity International won't support direct IPO participation. Even when secondary trading starts, you'll be dealing with CREST Depository Interests, currency conversion fees, and the absolute chaos of Wall Street's retail frenzy.
Here is what most people get completely wrong about investing in global tech. You don't need a US brokerage account or a mountain of dollars to get early access to the world's most aggressive growth stories.
Honestly, the best way to own SpaceX right now is through the London Stock Exchange.
It sounds like a joke, but it's completely true. SpaceX has essentially been operating as a UK growth stock by proxy for years. British savers who bought into standard London-listed investment trusts are currently sitting on billions of dollars of Elon's space empire.
The Edinburgh Fund Managers Who Beat Wall Street
While American retail investors were waiting for an S-1 filing to drop, fund managers in Edinburgh were busy writing checks.
Baillie Gifford, the asset management giant behind the Scottish Mortgage Investment Trust (SMT), first bought into SpaceX way back in December 2018. They put in a relatively modest $200 million. By March 2026, that single bet had skyrocketed to a value of nearly $4 billion.
Because of the unique structure of UK investment trusts, these funds can hold massive stakes in private companies. British rules allow these trusts to pack up to 60% of their portfolios with unlisted assets. That's a structural advantage American mutual funds simply don't have.
When Baillie Gifford adjusted its internal valuations in June 2026 to match the confirmed $135 IPO price, the numbers went wild. Scottish Mortgage saw its SpaceX exposure jump to a concentrated 21% of its entire portfolio.
Think about that for a second. If you buy shares in SMT on the London Stock Exchange today, more than a fifth of your money is instantly deployed into Starlink satellites and Starship rockets. You aren't just getting exposure; you are getting a massive, concentrated position that has driven the trust's market value up by 42% over the last six months.
Where to Find the Most SpaceX on the London Stock Exchange
Scottish Mortgage is the biggest name in this space, but it isn't the only one. In fact, if you want pure-play exposure without waiting for the secondary market to settle down, a handful of London-listed trusts have made Musk their top bet.
- Edinburgh Worldwide Investment Trust (EWI): This trust currently holds the crown with an astonishing 22% portfolio weighting in SpaceX.
- Scottish Mortgage (SMT): Sitting right behind at 21% concentration, representing a £3.5 billion stake.
- Baillie Gifford US Growth Trust (USA): Holds a 16.5% position, making SpaceX its largest underlying asset.
- Schiehallion Fund (MNTN): A dedicated private-equity focused vehicle holding a 14.5% stake.
Outside of the Baillie Gifford stable, you can look at RIT Capital Partners (RCP), which carries about a 3% weighting.
If you buy any of these trusts, you are bypassing the entire IPO circus. You don't have to worry about whether your broker will execute your order at the opening bell or if you'll get crushed by a sudden drop when the first lock-up period expires later this summer. You are buying in at the net asset value of the fund, often at a discount.
The Starlink Reality Check
Let's look at why people are treating this IPO like the second coming of Nvidia.
A lot of casual observers think SpaceX is just about launching big metal tubes into the sky for NASA. Rockets are cool, but they don't justify a $1.78 trillion valuation. The real value engine here is Starlink.
Starlink is rebuilding the global internet infrastructure from low Earth orbit. It's pulling in millions of subscribers across 100 countries, dominant in maritime, aviation, and rural connectivity. It has low latency, high margins, and basically no real competitors right now.
Goldman Sachs is telling institutional clients that SpaceX's revenues could surge 100-fold by 2050. That's the kind of math driving the current mania.
But you need to be careful. Morningstar analysts put out a fair value assessment this month pegging the company's true worth at $780 billion. That means the public market IPO is looking to price the business at more than double its current independent valuation. At $1.78 trillion, SpaceX is trading at roughly 100 times its annual sales. Microsoft trades at 12 times. Apple trades at less than seven.
If you buy individual shares on day one, you are paying a massive premium for hype.
The Smarter Way to Play the Space Boom
This is where the UK investment trust strategy becomes genuinely useful. If you buy Scottish Mortgage or Edinburgh Worldwide, you aren't just buying SpaceX at the top of the market. You are buying a diversified portfolio managed by people who got in at the ground floor.
It also solves the liquidity trap. Pre-IPO investors face strict lock-up restrictions. According to recent S-1 amendments, early shareholders can only dump up to 20% or 30% of their stock after the Q2 results drop in late summer. Full liquidation takes time. As a retail investor buying individual stock, you could easily get caught in the crossfire when those tranches unlock and insiders start cashing out.
By using a London-listed trust, you can buy and sell your shares instantly during UK market hours. The fund managers handle the lock-ups; you just trade the trust.
If you want to act on this space thesis today, stop looking at US brokerages. Check your current UK ISA or SIPP provider. Search for tickers like SMT or EWI. Look at the current discount to net asset value. By purchasing the trust, you effectively secure your allocation in the world's largest aerospace monopoly before the Wall Street opening bell even rings.
