June 12, 2026, marked a historic milestone as SpaceX officially debuted on the Nasdaq, completing the largest IPO in human history. The company raised $75 billion at an offering price of $135 per share, reaching a valuation of $1.77 trillion. On its first trading day, SpaceX closed at $160.95 per share, up 19.2%, pushing its market cap past $2.1 trillion.
On the same day, ARK Invest, led by Cathie Wood, disclosed a highly anticipated trading report. Known for its bets on "disruptive innovation," this asset management firm purchased approximately 3.29 million SpaceX shares across multiple ETFs on the IPO day, deploying about $443 million. At the same time, ARK significantly reduced its holdings in established tech giants such as AMD, Tesla, Baidu, and Roku.
This was far more than a simple portfolio adjustment. Instead, it was a well-structured reallocation—selling mature tech assets that had already seen substantial gains and concentrating capital into the newly public leader of the space economy. This move reveals more than just ARK’s stock picks; it signals a broader trend: the space sector is entering the mainstream radar of institutional investors.
What was the specific roadmap for this portfolio reallocation?
ARK’s SpaceX purchases did not come from open market bidding. Instead, they were executed through the ARK Venture Fund, a private investment vehicle. According to transaction records confirmed as of June 13: ARK Innovation ETF (ARKK) bought 1,690,839 shares, accounting for about 3.28% of the fund’s portfolio; ARK Autonomous Technology & Robotics ETF (ARKQ) acquired 736,442 shares, or 2.65% of its portfolio; ARK Space Exploration & Innovation ETF (ARKX) held 538,341 shares, representing 6.89% of its portfolio; and SpaceX’s weight in the ARK Venture Fund climbed to 11.38%.
All four ETFs acquired the same stock simultaneously, and these positions were established via private placements rather than on the secondary market. This means ARK had secured these shares in the private market before the IPO. The pricing for these shares was determined through private negotiations, not public market quotes—in essence, ARK locked in its "ticket" before SpaceX officially went public.
Looking at the structure, ARK wasn’t simply betting on a single theme. Instead, it allocated SpaceX across four ETFs from different angles: ARKK, as the flagship innovation fund, took the largest position; ARKX, focused on the space theme, gave SpaceX the highest portfolio weight; ARKQ and ARKW approached from robotics and next-generation internet perspectives, respectively. This multi-pronged allocation underscores ARK’s view of SpaceX as a foundational asset spanning multiple innovation tracks.
What does the simultaneous reduction of AMD and Tesla reveal about ARK’s asset reallocation logic?
To make room for SpaceX, ARK systematically trimmed existing positions on the same day.
AMD was the largest reduction. Through ARKQ, ARKW, and ARKX, ARK sold a total of 80,536 AMD shares, cashing out around $39.3 million. This continued a multi-week trend. As early as June 1, all five ARK ETFs had already reduced AMD holdings by over 110,000 shares while adding about 300,000 shares of Nvidia. Combined, ARK’s AMD exposure has been significantly reduced.
As for Tesla, ARK sold about 39,850 shares for approximately $15.9 million. Notably, Tesla remains the largest holding in ARK’s flagship ARKK fund. This reduction is not a full exit but a structural adjustment to the position size.
Additionally, ARK sold 98,835 shares of Roku (about $11.8 million), 67,420 shares of Baidu (about $7.8 million), and 50,700 shares of Rocket Lab (about $5.82 million). The sell list spans chips, autonomous driving, streaming, cybersecurity, and more, signaling a comprehensive capital restructuring of ARK’s portfolio.
The assets reduced—AMD, Tesla, Roku, Baidu, CrowdStrike, and others—are mostly mature tech companies that have already experienced significant valuation recovery or price gains in recent quarters. ARK’s selling does not necessarily reflect a negative long-term outlook on these companies. Rather, it fits a "sell high, buy new" framework: reallocating realized gains toward assets ARK sees as being at the start of a bigger narrative.
What is ARK’s core valuation anchor for its bold bet on SpaceX?
ARK’s valuation logic for SpaceX is not based on current profitability.
In 2025, SpaceX posted annual revenue of about $18.7 billion but a net loss of $4.9 billion, with only the Starlink business turning a profit. At its IPO valuation of $1.77 trillion, SpaceX’s price-to-sales ratio reached about 93x—a figure hard to justify by traditional financial standards. Yet ARK’s logic explicitly rejects the traditional framework.
According to CNBC, ARK stated before the IPO that Starlink alone could justify a $2 trillion valuation for SpaceX, citing user growth far exceeding expectations—active users have surpassed 10 million, and 2026 revenue is projected to exceed $20 billion. The global satellite connectivity market is estimated at $160 billion annually, and Starlink has the potential to capture a significant share.
Beyond Starlink, ARK sees two other growth engines for SpaceX. First, Starship: once the technology matures, it could lower space launch costs from thousands of dollars per kilogram to under $100, fundamentally reshaping the cost structure of the space economy. Second, after merging with xAI, SpaceX’s prospects in orbital AI infrastructure—ARK even believes this area could eventually surpass Starlink’s current business in potential.
Based on this framework, ARK’s internal models forecast SpaceX’s medium-to-long-term valuation: about $2.5 trillion in enterprise value in a base-case scenario for 2030, $3.1 trillion in an optimistic case, and $1.7 trillion in a pessimistic case. In other words, even if the IPO price reflects the "lower bound" of ARK’s model, there is still significant upside potential over the long term.
Is the space economy entering the mainstream of institutional asset allocation?
ARK’s concentrated $443 million purchase coincided precisely with the SpaceX IPO, but its decision logic extends beyond a single stock’s listing window. From a broader perspective, this may signal the emergence of the space economy as a distinct asset class within institutional investment frameworks.
According to the 12th edition of the Novaspace "Space Economy Report," the global space economy reached $626 billion in 2025—double its size a decade ago—with commercial activity accounting for about 78%. McKinsey is even more optimistic, projecting the global space economy to grow from around $630 billion in 2023 to $1.8 trillion by 2035.
The industry chain is expanding rapidly. Core sectors include rocket launch services, low-Earth orbit satellite internet, commercial remote sensing, and satellite navigation. Meanwhile, emerging fields such as space tourism, space computing, space manufacturing, and in-orbit services are taking shape. Starlink now has over 10,000 satellites in orbit, accounting for more than 60% of all global satellites.
It’s important to note that the institutional allocation path for the space economy differs structurally from the previous AI boom. AI’s surge was driven by major breakthroughs in large model technology, with capital markets moving from proof of concept to value realization in just two years. The space economy, by contrast, is more akin to infrastructure—its growth curve is slower but more predictable, and its key commercialization milestones (like reusable rocket maturity and low-Earth orbit network deployment) are more engineering-driven and require long-term capital.
ARK’s allocation provides a window into institutional attitudes toward the space sector. However, whether a single institution’s concentrated bet will become a systemic trend depends on whether more players believe the space economy will undergo an "AI-style revaluation"—that is, whether the market will price in future growth ahead of actual commercialization.
How do capital concentration and valuation divergence create a two-way constraint?
A notable tension in ARK’s recent moves is the 11.38% single-position weight, which reflects both strong conviction and a concentration risk at the fund level.
As of May 31, SpaceX accounted for 11.38% of ARK Venture Fund’s net assets, making it the fund’s largest holding. This figure was even higher—17.02%—as of March 31. Concentrating more than a tenth of the fund’s net assets in a single private holding means SpaceX’s post-IPO price performance will directly and significantly impact the fund’s NAV.
Meanwhile, Wall Street’s valuation estimates for SpaceX are wildly divergent. Oppenheimer set a $190 price target, breaking down the valuation as "Starlink anchors cash flow, Starship controls costs, and space AI data centers serve as long-term call options." In contrast, CFRA issued a "sell" rating on IPO day with a $115 target, warning that Starlink’s profits could be consumed by the cash-hungry xAI and Starship projects. Morningstar analyst Nicolas Owens used a discounted cash flow model to estimate SpaceX’s fair value at just $780 billion, or about $60 per share, arguing that xAI could become a "value destroyer."
The core debate centers on whether Starlink’s profits can support two massive, still-investing projects—Starship’s development and xAI’s AI infrastructure expansion. After SpaceX acquired xAI in February 2026, its business model shifted from "aerospace + communications" to "aerospace + communications + AI," but the AI business remains loss-making and is "burning" cash. The IPO prospectus indicates that expanding AI computing capacity is a clear use of proceeds, suggesting that losses may not narrow in the short term.
The fundamental difference between ARK and the bears is the time horizon. ARK values SpaceX based on 2030 projections, willing to pay a premium today for the "mature Starship + orbital AI" narrative; the bears anchor their view on medium-term cash flows and see the valuation as severely overextended. These perspectives are fundamentally irreconcilable—they are based on different time preferences and risk models, with no absolute right or wrong.
Conclusion
On SpaceX’s IPO day, ARK bought about 3.29 million shares for $443 million and systematically reduced positions in AMD, Tesla, and other tech stocks—a clear signal of asset allocation rotation.
Drilling into the details, this was not a passive index rebalance or marginal tweak. It was a set of directional, proactive decisions: selling semiconductor, autonomous driving, streaming, and cybersecurity stocks that had already posted strong gains, and concentrating capital into the newly public leader of the space economy. AMD, after a surge in May, continued to be trimmed, while Tesla, though reduced, remains ARKK’s top holding. Overall, this was a "sell partial gains to buy into a new narrative" move, not a wholesale rejection of legacy tech assets.
From an industry perspective, ARK’s allocation comes as the global space economy has surpassed $620 billion and is projected to approach $1.8 trillion by 2035. Starlink’s user base has topped 10 million, reusable rocket technology is maturing, and the concept of orbital AI infrastructure is moving from abstract to tangible. These factors together provide an objective foundation for the space sector as a long-term institutional allocation theme.
Yet ARK’s aggressive positioning also amplifies the core debate: Is SpaceX’s valuation anchored in Starlink’s proven cash flows, or does it rest more on the "long-term call options" of Starship and xAI? Bears argue the valuation is overblown; bulls are willing to pay a premium with 2030 as their target year. Which view the market validates will depend on Starship’s commercialization pace, whether xAI can turn "orbital AI data centers" from vision to operational reality, and whether Starlink’s growth can support the group’s cash flow needs.
For market participants, ARK’s reallocation is not an investment signal per se, but it offers a case study in how institutions are pricing the space sector. Unlike the AI boom three years ago, the space economy’s growth path relies more on actual infrastructure buildout than on a single technological breakthrough. This means its "revaluation" may be more gradual and will test the patience of long-term capital.
FAQ
Q1: Did ARK buy SpaceX shares from the secondary market on IPO day?
No. The approximately 3.29 million SpaceX shares ARK acquired came through the ARK Venture Fund’s private equity channel. Essentially, these were pre-IPO private placements that were subsequently converted, not shares purchased via public bidding on Nasdaq on IPO day.
Q2: How many AMD and Tesla shares did ARK sell?
On June 12, ARK sold about 80,536 AMD shares across ARKQ, ARKW, and ARKX, cashing out roughly $39.3 million. It also sold about 39,850 Tesla shares for about $15.9 million. It’s important to note that Tesla remains the largest holding in ARK’s flagship ARKK fund; this reduction was not a full exit.
Q3: Why is ARK so bullish on SpaceX?
ARK sees three growth engines for SpaceX: Starlink (a profitable, validated business with over 10 million users), Starship (which could lower launch costs to under $100 per kilogram), and, following the xAI merger, orbital AI infrastructure. ARK’s internal models project a base-case valuation of about $2.5 trillion for SpaceX by 2030.
Q4: How did SpaceX shares perform on IPO day?
SpaceX went public on Nasdaq on June 12, 2026, at $135 per share and a $1.77 trillion valuation. The stock closed at $160.95, up 19.2%, and hit an intraday high of $176.52, for a peak gain of over 30%.
Q5: How divided is Wall Street on SpaceX’s valuation?
Wall Street’s price targets for SpaceX range widely, from $60 to $190 per share. Optimists (like Oppenheimer) see SpaceX as a once-in-a-century "space + AI" growth story; skeptics (like CFRA and Morningstar) believe the valuation is far beyond what fundamentals can support, warning that xAI and Starship could continue to drain cash.
Q6: How large is the space economy today?
According to the 12th edition of the Novaspace "Space Economy Report," the global space economy reached $626 billion in 2025, about double its size a decade ago. McKinsey projects it will grow to $1.8 trillion by 2035.
