Space ETFs Are Riding A SpaceX Narrative They Cannot Deliver

The money is pouring in, but the trade is broken.

Space-related ETFs are absorbing capital at the fastest rate since 2021. The Procure Space ETF (UFO) has seen two-thirds of its total inflows arrive in the last 12 months, with 20% of that coming in the last month alone, according to Morningstar Direct. UFO is up roughly 133% year-to-date. Cathie Wood's ARK Space & Defense Innovation ETF (ARKX) has followed a similar arc, climbing from a 52-week low near $20 to around $35 as of late May.

The catalyst driving the rush is obvious: SpaceX filed its S-1 prospectus on May 20 and is targeting a Nasdaq debut as early as June 12, seeking to raise roughly $75 billion at a $1.75 trillion valuation. It would be the largest IPO in history.

Here is the part nobody wants to point out: none of these funds own SpaceX.

The proxy problem

UFO's top holdings are Rocket Lab (6.71%), Planet Labs (6.22%), Viasat (5.56%), and MDA Space (4.85%). ARKX has a different flavor, leaning into defense and space-tech names, but the SpaceX gap is the same. ARK Invest's own guide to the IPO acknowledges that its funds have no pre-IPO SpaceX exposure.

If you want actual SpaceX shares in a fund, the only pure-play vehicle is the Tema Space Innovators ETF (ticker: NASA). It is tiny, illiquid, and not the fund retail traders are buying. The money is going into UFO and ARKX because the tickers sound thematic and the performance is eye-catching, not because the holdings match the thesis.

This matters because the proxy names inside these ETFs are already priced for perfection - without the actual company that justifies the sector's narrative.

What you're actually buying

Rocket Lab, the largest UFO holding, delivered a strong Q1: $200.3 million in revenue, up 63.5% year-over-year, with positive adjusted EBITDA of $23 million for the first time. That is a real inflection point. But the stock trades at roughly 112 times EV/sales - up 86% from its 12-month average of 60. The multiple has already run far ahead of the earnings milestone.

Planet Labs and Viasat are smaller, less profitable names with uncertain paths to scale. Buying UFO as a SpaceX play means buying a basket of speculative space-adjacent companies at inflated multiples, then hoping the sector halo from SpaceX's IPO lifts everything together. That is not investing; it is narrative arbitrage.

SpaceX itself is not yet the bargain the multiple implies

The S-1 filing reveals a company that is massive and growing fast but still burning cash aggressively. Q1 2026 brought $4.69 billion in revenue but a net loss of $4.28 billion - compared to a net loss of just $528 million in the same quarter a year ago. SpaceX was profitable in 2024, posting roughly $800 million in net income. The Q1 2026 loss reflects heavy investment in Starship development and launch infrastructure.

Starlink is the money machine: $11.4 billion in revenue in 2025, up 48%, accounting for 61% of total revenue and generating $4.4 billion in operating profit. But at a $1.75 trillion target valuation, SpaceX is being priced as if Starship achieves orbit reliability, Starlink hits broadband-scale saturation, and the launch cadence doubles - all within the next two to three years. That is a lot of execution packed into a single multiple.

The risk/reward math on the ETF trade

When SpaceX actually lists, the dynamic could break in unexpected directions. If SpaceX prices at or near its $1.75 trillion target, the post-IPO stock will become the obvious space exposure. UFO and ARKX look like the wrong vehicle then - they own the runners-up, not the leader. If SpaceX prices lower due to demand concerns or its loss trajectory, the sector sentiment could crack, and the same ETFs will drag with no SpaceX cushion to offset the fall.

Either way, the ETF investor is on the wrong side of the trade. The funds are expensive - UFO charges a 0.75% expense ratio on a basket of companies that may get outshone by the very company they can't hold.
