SpaceX's Lock-Up Calendar Looms Large as 13F Filings Reveal a Concentrated Shareholder Base
Published on 08/19/2026 at 08:22 | Redaktion boerse-global.de
The countdown to Thursday's unlock of 319 million SpaceX shares has thrown a spotlight on just how concentrated the company's institutional ownership has become. Fresh 13F filings paint a picture of hedge funds, tech giants, and even university endowments betting heavily on Elon Musk's space-and-AI conglomerate — some to a degree that borders on the extreme.
That disclosure wave arrives as the stock wrestles with a supply overhang that keeps growing. Thursday's release follows the August 6 unlock of 912 million shares, which initially weighed on the price before the equity recovered roughly 15 percent. September and October are set to bring further tranches of more than 700 million and around 650 million shares, respectively, according to reports.
A Shareholder Register Dominated by Bold Bets
The 13F data reveals remarkable concentration among SpaceX's largest holders. D1 Capital, run by Dan Sundheim, leads the hedge fund pack with 126 million shares worth over $21.5 billion — a position that represents 61 percent of the fund's entire US equity book. Darsana is even more concentrated: its 101 million shares, valued at $17.3 billion, account for 78 percent of the portfolio. Millennium, Coatue, and Balyasny also appear among the institutional holders.
The biggest positions, however, sit with strategic investors from the technology world. Alphabet holds 551.2 million shares worth roughly $94 billion — an extraordinary return on a $900 million investment made back in 2015, now worth about a hundred times that initial outlay.
Nvidia's 13F shows 122.8 million shares valued at approximately $21 billion, making SpaceX the chipmaker's second-largest equity stake after Intel. Saudi Arabia's Public Investment Fund holds 154.1 million shares worth around $26.3 billion, while Fidelity rounds out the heavyweights with 302.6 million shares.
Should investors sell immediately? Or is it worth buying SpaceX?
The concentration extends beyond the usual suspects. Harvard's endowment has bundled more than half of its US equity portfolio — $2.2 billion — into SpaceX. Italy's Intesa Sanpaolo holds 5.66 million shares, representing roughly a third of its entire US stock portfolio, though the recent pullback has trimmed that position's value from about $966 million to roughly $809 million.
The Bull-Bear Chasm Widens
The analyst community remains deeply divided on fair value. At one extreme, Phillip Securities' Glenn Thum maintains a Sell rating with a 12-month target of just $75 — implying nearly 50 percent downside from recent levels. Former Fidelity manager George Noble goes further, calling SpaceX one of the best short candidates on the market with a fair value of only $30, criticizing the stock's index inclusion as a "manufactured squeeze."
On the other side, Deutsche Bank lifted its 2027 revenue forecast to $115 billion from $97 billion following the Cursor deal, with a Buy rating and $235 price target. UBS sees fair value at $210, while JP Morgan's $240 target rests on second-quarter revenue that nearly doubled and AI-segment growth of roughly 250 percent. The consensus across 31 analysts sits at $232.35, with targets ranging from $75 to $800.
Skeptics outside the sell-side echo the bears' concerns. Jim Chanos calls the $1.75 trillion valuation unjustified, while valuation expert Aswath Damodaran pegs fair value at $1.3 trillion.
Cursor Deal Seals the AI Narrative
SpaceX completed its $60 billion acquisition of Anysphere, parent of AI coding platform Cursor, on August 14. Cursor shareholders receive approximately 389 million SpaceX shares in exchange. The deal underpins the company's push into artificial intelligence, where xAI revenue grew 247 percent to $2.6 billion in the second quarter — though the segment continues to post heavy losses.
Operationally, momentum is real: second-quarter revenue jumped 92 percent to $7.8 billion, while Starlink subscribers doubled to 12 million. Elon Musk has said the company now targets $1 trillion in annual revenue by 2030, a year earlier than originally planned. Goldman Sachs sizes the global space economy's potential at $1.8 trillion by 2035.
SpaceX at a turning point? This analysis reveals what investors need to know now.
The Capital Appetite Question
KeyBanc's Michael Leshock warns that funding those ambitions will be expensive. Scaling AI compute capacity to 6-7 gigawatts by end-2027 requires $250-300 billion, he estimates, with another roughly $325 billion in capital raises expected over the next 18-24 months. Second-quarter capital expenditures of $18.4 billion blew past expectations of $6 billion.
Bernstein's Doug Harned backs the long-term story with a $248 target but notes that the AI ambitions hinge on the success of Starship's full reusability — the foundation for planned orbital data centers.
In German trading Tuesday, the stock slipped 1.8 percent to €124.22, though it remains up 18 percent on the month and sits 36 percent above its 52-week low. Thursday's unlock will test whether the breadth of institutional support can absorb the added supply pressure once again.
