Showing this figure isn’t just science fiction, we had two developments last week. First, there was NASA’s successful Artemis II rocket launch that sent humans towards the Moon for the first time in over 50 years. Second, industry juggernaut SpaceX has reportedly filed to go public at a potential valuation of $1.75trn.

Here are three stocks to consider buying for exposure to the booming space economy.

SpaceTech fund

Let’s start with Seraphim Space Investment Trust (LSE:SSIT). This £365m trust invests in earlier-stage growth companies involved with space technology (SpaceTech).

The stock’s had an amazing run, going from 51p to above 150p in just 12 months.

However, this hasn’t been driven by mere hype, but actual tangible progress made by its portfolio companies. In March, it announced a 20% jump in its net asset value (NAV), or an increase of £56.4m.  

For example, Finnish microsatellite firm ICEYE secured a massive €1.7bn space reconnaissance contract from the German government alongside its partner, defence giant Rheinmetall. ALL.SPACE, HawkEye 360, and D-Orbit also received meaningful valuation uplifts.

It’s worth noting that seven of the trust’s top 10 holdings expect to report EBITDA profitability in 2026. So these are far from starry-eyed start-ups in garages.

The biggest risk would be Europe turning off the funding tap. However, while this can’t be ruled out, I think President Trump threatening to leave NATO makes it even more likely that Europe spends hundreds of billions building out its own space and defence capabilities.

If so, then many of the key holdings here should benefit massively. As I write, the trust’s trading at a 5% premium to NAV, suggesting that its valuation is far from bonkers.

European blue chip

Next, we have Airbus (ENXT:AIR), whose share price is down roughly 22% since January.

While primarily a maker of passenger jets, Airbus also has a Defence and Space division. Last year, revenue here increased 11% year on year to €13.4bn, while order intake surged to a record €17.7bn.

Airbus built the European Service Module for NASA’s Artemis programme, providing power and life support for the Orion spacecraft heading to the Moon.  

Rather than a pureplay space stock, Airbus is a stable, profitable giant with a massive backlog of 8,754 commercial aircraft. Supply chain shortages could result in production delays, but the forward price-to-earnings multiple of 22 looks reasonable to me.

AIM-listed stock

Returning to SpaceX, let’s end with Filtronic (LSE:FTC). This is a small-ish UK company with a £435m market-cap that designs and manufactures advanced radio frequency (RF) solutions for the space, aerospace and defence, and telecoms markets.

A deal signed with SpaceX to support SpaceX’s Starlink satellite constellation has been transformative. Revenue ballooned from £16.3m in 2023 to £56.3m last year.

The flip side to this is that SpaceX now makes up the vast bulk of revenue, which adds concentration risk. However, it’s worth noting that Filtronic is having success diversifying revenue streams.

For example, last week it was selected by a major European defence firm to provide it with components, building on an $8m contract won with the US army the week before.

Incredibly, the British billionaire earned an estimated $18.9bn in net gains for those invested in his TCI Fund Management. This was the biggest single-year gain on record for a hedge fund!

With an annualised return of roughly 18% since 2004, TCI is now fifth on the list of the most profitable hedge funds of all time. 

How has Hohn achieved this? And what can investors learn from it? 

Wide-moat strategy

The money manager’s strategy is notoriously concentrated – often just nine or 10 stocks – and he looks specifically for natural monopolies. These are businesses with extremely strong competitive advantages (what Warren Buffett would call deep moats). 

TCI’s largest holding, engine maker GE Aerospace, surged roughly 85% in 2025. Gains also came from longstanding positions in Microsoft, Visa, Moody’s, and infrastructure firm Ferrovial.

Meanwhile, Google parent Alphabet jumped 65%! 

What stands out to me is that these businesses operate in industries where the barriers to entry are very high. For example, once an airline buys a GE engine, it’s essentially locked in for 20+ years of high-margin servicing and parts. 

Meanwhile, Microsoft’s annual capital expenditure is currently $140bn-$150bn. This is the entry price to play in the hyperscale cloud computing sandbox, limiting competition to a small handful of players. 

Visa is one-half of a global duopoly in payments, while holdings Canadian Pacific Kansas City and Canadian National Railway operate irreplaceable rail networks.

Focus on the long term

So, what can investors learn from this? One takeaway could be to focus on hard-to-replace companies in industries with high barriers to entry.

Crucially, Hohn is a long-term investor. TCI’s average holding period is around eight years, with some positions held for over 13 years. So he lets high-conviction winners run as large positions.

Wealth is built by finding high-quality companies trading at fair prices, then letting compounding work its magic over years and decades. 

A stock to consider

A smaller holding that also did well for TCI last year was Airbus (ENXT:AIR). Shares of the plane maker rose about 40%.

Airbus has many of the qualities already discussed. In the wide-body and narrow-body aircraft market, it operates a global duopoly with Boeing. It’s nearly impossible for a new competitor to succeed due to the extreme capital requirements and technical complexity.

Hohn likes businesses that have essential products with long-term, predictable demand. Airbus certainly ticks this box, having ended 2025 with a record backlog of about 8,754 aircraft waiting to be delivered. 

That’s a 10-year wait for certain models! 

That said, production bottlenecks are a constant challenge. Last year, the plane manufacturer lowered its target to 790 jets from around 820. So supply chain problems are a key risk.

Nevertheless, an additional 1.5bn people are expected to join the middle classes globally by 2044, according to Airbus. And this stock is arguably the ultimate play on global travel growth.

Airbus is trading at 21 times next year’s forecast earnings, which strikes me as reasonable for a deep-moat company like this. As such, I reckon it’s worth considering for long-term investors.
