$10,000 parked in the Procure Space ETF (NYSEARCA:UFO) on May 29, 2025 at $24.64 was worth roughly $26,500 twelve months later, and most of that move happened in the last four months. UFO closed last Friday at $65.31, up 69% year to date and 165% over the trailing year. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY | SPY Price Prediction) is up 11% YTD over the same window. Almost no one outside the small space-investing corner of the internet was talking about UFO until Benzinga ran a piece on May 29 noting the fund had just crossed $1 billion in AUM.
The arithmetic, without the cherry picking
Pick any window and UFO has been laundering risk into return. Year to date, the fund went from $38.65 on December 31, 2025 to $65.31 on May 29, 2026. One month alone, April 29 to May 29, the fund ran 32%. That last figure matters because it tells you the YTD number is not a January story. The bulk of the move is recent, and recent moves on thin-volume thematic ETFs are the kind that get reversed when the catalyst slips.
The one-year number is the more honest framing for what people mean when they say UFO “tripled.” A 165% gain is not quite a triple, but starting from a depressed base around $24.64 a share last May, it functionally was for anyone who bought near the lows. Stretch the lens further and the picture cools. Over five years, UFO is up 135% against SPY’s 80%, which is real outperformance, but it took until 2026 for the gap to open up. For most of the fund’s life since its April 2019 inception, UFO bled relative to the S&P, and the people holding it were holding a thesis, not a winner.
What actually did the work
UFO tracks the S-Network Space Index, a basket of companies that derive most of their revenue from satellite operations, launch services, defense space contracts, and the adjacent ground-and-aerospace plumbing. The top holdings cited across recent coverage include Rocket Lab USA, AST SpaceMobile, Planet Labs, Iridium Communications, MDA Space, ViaSat, and Garmin. Those names tell you most of what you need to know. UFO is a concentrated bet on the small and mid-cap companies that win when satellite broadband, Earth observation, and orbital launch demand all move in the same direction at once.
Three drivers stacked on top of each other to produce the run. First, a SpaceX IPO catalyst. Andrew Chanin, the CEO of Procure Holdings, has been telling anyone who will listen that an expected SpaceX IPO by the end of 2026 would likely make the company the top holding in UFO through index inclusion, with a rumored $1.5 trillion valuation on the offering. The whole basket has rallied as a SpaceX proxy trade, even though UFO currently holds no direct SpaceX exposure. Second, defense satellite contracts and the Space Development Agency award cycle pulled the orbital infrastructure names higher. Third, the April 10, 2026 NASA Artemis II splashdown reminded a generation of capital that the lunar program is a real budget line, not a slide deck.
Inflows confirmed the narrative was selling. UFO took in $321 million in net flows during April alone and crossed $1 billion in AUM on May 27, seven years after launch. That is the part of the move that looks structural. A fund that spent most of its life under $200 million in assets has become a vehicle institutional desks are using to express a thematic view they cannot easily get elsewhere, since the competing Tema Space Innovators ETF reached $1.27 billion in AUM over a similar window.
The valuation tax nobody is paying attention to
Here is the part that should slow you down. 60% of UFO’s holdings are pre-profit space companies sitting on a combined $1.85 billion backlog. Backlog is a pipeline of contracted work that still has to convert to revenue, and revenue still has to convert to earnings. Jack Hough at Barron’s flagged in late April that the basket was trading at over 100x earnings with many companies being pre-profit or thinly profitable, and recommended a more grounded approach using diversified aerospace and defense names with current cash flows. He wrote that before the April-to-May leg added another 30%+ on top.
The expense ratio is 0.75%, which is fine for a thematic fund but is not free. On a $10,000 position, you are paying $75 a year for the manager to track an index you could not buy as a retail investor anyway. That is the deal. You are renting the basket, not the alpha.
What you actually have to believe to stay long here
The mechanism that produced UFO’s 2026 is regime-dependent in a way that the run is hiding. You need three things to keep working at once. The SpaceX IPO has to actually price in 2026 and has to come in at or above the rumored valuation, because that is the lid keeping the multiples on the rest of the basket aloft. The Department of Defense FY2027 budget has to come through with the satellite contract awards the pre-profit names are counting on, and the federal procurement cycle has to translate that $1.85 billion backlog into recognized revenue at the cadence the market is currently pricing. And the execution milestones have to land, including Rocket Lab’s Neutron debut and AST SpaceMobile’s satellite deployment targets.
Any one of those slipping is digestible. Two of them slipping turns a 100x basket into a re-rating event. The leading indicators are not subtle. Watch the SpaceX S-1 filing if and when it appears. Watch DoD FY2027 budget markup language for the Space Force line items. Watch Rocket Lab’s quarterly cadence reports for Neutron and AST SpaceMobile’s BlueBird deployment updates. The space economy projected to reach $1 trillion in annual revenue by 2034 is the long-cycle bull case, and it is probably right. The question is whether the companies in UFO today are the ones that capture it, or whether they are the early-cycle plays that get diluted, acquired, or recapitalized somewhere between here and the destination.
UFO already did the easy work. The setup from here is a much higher valuation against a basket that still has to prove it can earn money, which means the next 70% will be harder to come by than the last 70%, and the conditions that have to hold are now specific enough that you can name them. If the SpaceX IPO slips into 2027, the trade you are sitting in changes shape whether or not anything else goes wrong.
