SpaceX: The Long Private Compounding

An IPO marks the end of a private story, not the start of value creation. SpaceX is the clearest case yet, and a reminder of where the next decade's wealth will be made.


On the morning of 28 September 2008, from a coral speck called Omelek Island in the Kwajalein Atoll, a slender rocket named Falcon 1 lifted off carrying nothing anyone wanted: a 165-kilogram aluminium mass simulator, a dummy payload designated RatSat. It was SpaceX's fourth attempt to reach orbit. The first three had failed. The company, founded six years earlier in 2002, was nearly out of money; the fourth rocket had been assembled in a hurry from spare parts after Elon Musk, days after the third failure, told his staff to launch again within six weeks. This time it worked. Falcon 1 became the first privately developed, liquid-fuelled rocket to reach Earth orbit. Before the year was out, NASA awarded SpaceX a $1.6 billion contract to fly cargo to the International Space Station, and a company that had been days from winding down suddenly had a future.[¹]


Eighteen years later, on 12 June 2026, SpaceX is expected to begin trading on Nasdaq under the ticker SPCX. Reuters reports the offering targeting roughly $135 a share, a raise of about $75 billion, and a valuation near $1.75 trillion, which would make it the largest IPO in history, comfortably ahead of Saudi Aramco's debut in December 2019.[²] Between the dummy payload and the record book sits the entire company: the reusable boosters, the Falcon 9 cadence, the Dragon capsules, and Starlink, the satellite-internet network that now does most of the work. Public-market investors get to buy in on the 12th. Almost everything that made the company worth $1.75 trillion happened before that date, in rooms they were never in.


That is the uncomfortable arithmetic of modern technology investing, and it frames the question this piece is really about: if the value is built in private, what is left for the investor who waits politely for the bell? SpaceX was one of the first assets we bought at Opportuna, in early 2025, at a valuation north of $300 billion. The IPO is a milestone. For us it is also a reminder of three things we believe.


Value is built before the bell


For decades, SpaceX compounded entirely outside public markets. By the time retail and index money can touch it, the company-building is largely done. This is not a SpaceX quirk; it is the new shape of the asset class. The line between venture, growth equity and public markets has moved, and it has moved late. The investor who shows up only for the IPO arrives after the interesting part.

The complication is that private markets have no agreed price. In public markets a disagreement about what a company is worth is settled, brutally, by the closing bell. In private ones it can persist for years. In 2025, a reported secondary sale was said to value SpaceX at $800 billion; Musk called the figure inaccurate.[³] Both numbers were "right" in the only sense that matters privately - someone was willing to quote them - because there is no Reg FD, no central order book, and no reference price to appeal to. What an asset is worth depends on who is transacting, where, and what they happen to know.


That opacity is the problem and the opportunity in the same breath. It is why the plumbing matters: as exits stay delayed, liquidity stays patchy, and pricing stays hard to read, a genuine opening has emerged in late-stage private technology for buyers who can do the work. Direct secondaries are how we step into it; scaled growth assets with a visible route to liquidity over three to five years, bought without the comforts a public investor takes for granted. The best description of the job we have heard is: "We are investing in stocks in the 80s." The point is not that public markets are irrelevant. It is that, by the time a company is obvious enough to list, the obvious money has already been made.

What deserves a premium


By early 2025 the rockets still grabbed the headlines, but Starlink had quietly become the engine. The connectivity business scaled from negligible revenue in 2021 to roughly $7.6 billion in 2024 - by some counts already the majority of SpaceX's top line [⁴] - on subscriber growth, expanding enterprise and government contracts, improving unit economics, and a spectrum position opening new products such as Direct-to-Cell. Crucially, it had real public comparables to benchmark against; this was not a faith-based number. Alongside it, the launch business, which carried some 87% of all payload mass to orbit in 2024, sat on advantages no rival could copy in a hurry: cadence, reuse economics, and deep integration with Starlink's own deployment. Growth, defensibility and optionality, rarely found together at that scale.


So we argued, internally, about whether $300 billion-plus was simply too expensive. It is the right argument to have, and usually the wrong place to stop. Peter Thiel, whose Founders Fund was an early SpaceX backer, likes to say that "competition is for losers," and that monopoly is "the condition of every successful business." The corollary for an investor is awkward but useful: the assets that deserve a premium are often precisely the ones that look expensive on today's numbers, because the price is paying for a position no competitor can take away. "Expensive" describes a multiple. It is not, by itself, a thesis. The discipline lies in telling apart a high price attached to a fragile business and a high price attached to an unrepeatable one, and SpaceX, a platform spanning launch, distribution, data, communications and strategic relevance, is about as unrepeatable as they come.


From frontier to infrastructure


The IPO will not be the end of the SpaceX story so much as the moment space stops being a frontier and becomes an asset class. The category is no longer about exploration or launch alone; it is turning into infrastructure; launch capacity, satellite connectivity, Earth observation, positioning, orbital logistics, AI-fed data layers, and eventually manufacturing in orbit. It also sits squarely on the fault line of sovereignty. Governments need independent access to orbit, secure communications, persistent monitoring, and redundancy across domains that are increasingly contested. Commercial demand and strategic scarcity rarely pull in the same direction; in space, for now, they do. Seen that way, SpaceX is less a singular success than the anchor tenant of a much larger investable ecosystem, and anchor tenants, as any landlord knows, are how you let the rest of the building.


SpaceX makes the headline because of the IPO. The more durable lesson runs underneath it: the most consequential technology companies now do their compounding in private, and the question that decides returns is no longer which company to own but whether you can reach it - at what price, and with a credible path back out. The dummy payload that limped into orbit in 2008 is, eighteen years on, the largest public offering ever written. Opportuna exists for the years in between; the long private compounding, where technology, infrastructure and sovereignty meet, and where the public market, true to form, gets the last look rather than the first.
