Space Boom: Key Space Stocks and UCITS ETFs Ahead of a Potential SpaceX IPO

Market Analysis

The space sector has moved from the playground of governments and billionaires into mainstream investor consciousness. While broad markets such as the DAX and the S&P 500 have traded mostly sideways or slightly down in 2026, specialised space names and dedicated space indices have delivered extraordinary returns, in some cases more than doubling in value. Momentum has been driven by rapid revenue growth at satellite network companies and renewed excitement around a potential listing by SpaceX the so-called IPO of the decade.

Three single stocks and three UCITS-compliant ETFs stand out for European investors. Planet Labs has been the runaway highflyer, posting almost 1,000% performance over the last 12 months as commercial demand for earth-observation data proves a lucrative business. Rocket Lab, the small-launch provider, also delivered substantial gains roughly 240% year-over-year supported by a record order backlog near $1.85 billion and the prospect of scaling its larger Neutron vehicle. AST SpaceMobile represents a higher-risk, higher-reward type of play: after a near-300% price surge in the past year, the company has begun to transition from R&D to revenue generation, reporting approximately $54 million in Q4 2025 a jump of more than 2,700% from the prior year.

For European investors who often face limited access to US-listed niche ETFs like the Procure Space ETF (ticker: UFO), three UCITS-compliant funds offer continental exposure to the space theme. VanEcks Space Innovators UCITS ETF targets companies focused on space technology and satellites and has delivered strong headline returns. First Trusts Indxx Global Aerospace & Defence UCITS ETF is oriented more toward critical infrastructure and ground-station operators, while iShares Global Aerospace & Defence UCITS ETF provides broader coverage that includes major aerospace and defence contractors. Reported one-year returns for these ETFs range from solid to spectacular, underscoring how concentrated growth in this sector has been.

What Investors Should Know

Much of the sectors current valuation momentum is tied to the so-called SpaceX effect. Prediction markets and market chatter peg the probability of a SpaceX IPO within the year at very high levels, and even rumours of a valuation in the trillions have produced a halo effect that lifts peers and suppliers. If SpaceX lists, the companys inclusion in space-themed ETFs would materially change weightings, likely drawing significant institutional capital into the sector.

That said, space remains a highly speculative area. Several top performers still burn cash Rocket Lab reported a negative cash flow of roughly $322 million in 2025 and extreme volatility is commonplace. Social-media-driven rallies can drive double-digit swings in a matter of days, making short-term trading perilous. For long-term investors, space plays are better understood as high-speed, high-risk bets on the infrastructure of tomorrow rather than as ballast for a conservative portfolio.

Investors considering exposure should weigh company fundamentals revenue growth, backlog, path to sustained profitability against the high volatility and capital intensity typical for the industry. UCITS ETFs give diversified access for European investors, while single-stock positions may offer outsized returns at the cost of higher risk. Regardless of entry point, tolerance for large intra-day and intra-week moves is essential.

In conclusion, the 2026 space rally has produced headline-grabbing winners and created more ways for European investors to participate. But beneath the glamour of rocket launches and satellite constellations, fundamental risks remain. Those who choose to invest should do so with a clear view of the speculative nature of the sector and a plan for the pronounced ups and downs that come with pioneering markets.
