The Biggest Financial Winners of the SpaceX IPO

The Institutional Machine

Beyond the named individuals and the pension fund, the institutional machinery of Silicon Valley and global finance is sitting on an astonishing pile of paper wealth.

Alphabet invested approximately $900 million in SpaceX’s 2015 Series F round alongside Fidelity. That position, diluted through subsequent rounds and the xAI merger to roughly 5%–6.11%, is now estimated to be worth $87 billion to $107 billion — a return of approximately 100x on the original investment. For a company of Alphabet’s size, this crystallizes what analysts call a “hidden” balance sheet asset that could theoretically fund years of AI capital expenditure.

Sequoia Capital, which entered during the 2021 Series J round with approximately $2 billion in total investment, now holds roughly 1.5% of the combined entity — a position valued at over $20 billion, roughly a 10x return. Fidelity holds SpaceX across multiple funds, with its Contrafund alone holding over $8 billion as of mid-2026. Andreessen Horowitz led the 2023 $750 million round at a $137 billion valuation and is now set for “record returns” per Bloomberg. Baillie Gifford holds exposure through multiple trusts including Scottish Mortgage and Edinburgh Worldwide.

Hedge funds D1 Capital Partners and Darsana Capital Partners are sitting on estimated paper profits of $15 billion to $20 billion combined. The pattern is consistent: the earlier you got in, the more spectacular the numbers. A 2015 investor is looking at roughly 146–175x. A 2019 investor at ~57x. A 2021 investor at ~24x. Even those who bought in the 2023 round at $137 billion are sitting on approximately 12.8x in less than three years. The entire venture capital ecosystem’s best-performing fund of the decade might simply be “the one that had the most SpaceX.”

Paper Wealth vs. Real Wealth

Every single number in this article — the $735 billion, the $106 billion, the $11.6 billion, the $60 billion, all of it — is paper wealth. Mark-to-market valuations based on a price set by a 4% initial float on day one of public trading. Nobody profiled above has sold a share. Nobody has “made” anything. They hold positions. Positions can change.

SpaceX’s lockup structure is unusual and tiered. Rather than the standard 180-day cliff, insiders will be allowed to sell in staggered tranches: 20% after Q2 2026 earnings, an additional 10% if the price sustains 30% above IPO for a specified period, then 7% chunks every few weeks from day 70 through day 135, another 28% after Q3 earnings, with all remaining shares unlocking at 180 days post-IPO around December 2026. Reuters described this approach as turning “a tsunami into constant pounding” — spreading the selling pressure but creating months of persistent uncertainty.

Post Lock-Up Period

History is not kind to post-lockup price action. When Palantir’s lockup expired, the stock dropped 13% in a single session. Uber hit all-time lows on its lockup expiration date. SpaceX’s staggered structure may mitigate the cliff effect, but it introduces something potentially worse: a slow, grinding six-month window where new supply hits the market every few weeks. With a tight 4% float, even modest insider selling could produce outsized volatility. The counterarguments exist. Nasdaq-100 inclusion — potentially as early as 15 trading days post-IPO — would force index funds to become mandatory buyers. Ron Baron and BlackRock have publicly stated intentions to hold or increase positions. Those are real factors — but so are the structural supply dynamics of the next six months, and the two will be working against each other. 

And then there is the balance sheet. SpaceX carries $29.1 billion in long-term debt as of March 2026. It posted a $4.9 billion GAAP net loss in 2025, driven by heavy AI/xAI capital expenditure, Starship R&D, and debt servicing. These are not the financials of a company that justifies a $1.75 trillion valuation on fundamentals alone. They are the financials of a company that justifies it on narrative — and narrative is a volatile commodity.

The Valuation Question

Is $1.75 trillion justified? The bull case is not frivolous. Starlink generated $11.4 billion in revenue in 2025, growing subscribers from 4.6 million to over 10 million by March 2026, with a 63% EBITDA margin. That is a legitimate cash-generative business with a defensible moat. Launch services contribute another $4 billion, underpinned by NASA contracts and the Starshield military program. ARK Invest’s bull case targets $2.5 trillion by 2030.

But the bear case is equally real. Morningstar’s fair value estimate sits at $600 billion to $800 billion, implying the market is paying a 2–3x premium over what a disciplined fundamental analysis suggests the company is worth. The xAI segment generated $3.2 billion in revenue but is burning cash at a rate that makes the rest of the AI industry look fiscally responsible. Starlink’s average revenue per user declined 18% between 2023 and 2025 as the company traded price for volume, a strategy that works until it doesn’t.

The broader context matters too. Across the AI sector, we are witnessing a pattern where major companies generate enormous revenue but struggle to produce actual profits, the costs of compute, training, and infrastructure consistently eating the margin. SpaceX’s xAI segment fits this pattern precisely: impressive top-line growth masking a capital expenditure problem that has no obvious near-term solution. And as I’ve written previously, the assumption that government contracts and public subsidies will backstop these economics forever is an assumption, not a guarantee.

Betting on the Future

At ~94x revenue with a net loss, the $1.75 trillion valuation is not pricing in what SpaceX is today. It is pricing in what SpaceX might become in five to ten years if everything goes right Starship achieves routine operation, Starlink reaches hundreds of millions of subscribers, xAI becomes profitable, and government contracts continue expanding. That is a lot of “ifs” for a price tag that leaves no margin for error.
