SpaceX went public in June 2026 at $135 per share, landing a valuation of roughly $1.8 trillion. That number makes it one of the most valuable companies ever to debut on a stock exchange. But the real story isn’t the IPO itself. It’s the years of quiet positioning by investment firms that built billions in exposure long before ticker SPCX ever appeared on Nasdaq.
The IPO raised approximately $75 billion, a staggering sum that dwarfs most public offerings in history.
The early believers and their returns
Baron Capital started buying SpaceX shares in 2017, eventually investing around $2 billion into the company. By mid-2026, that stake had ballooned to an estimated $12 billion. As of March 31, 2026, SpaceX comprised 33% of Baron Partners Fund, a $10.4 billion vehicle.
Then there’s Founders Fund, the venture capital firm co-founded by Peter Thiel. They were even earlier, investing in SpaceX back in 2008. Their roughly 3% stake was valued at over $50 billion based on the IPO pricing.
Valor Equity Partners held a stake valued between $75 billion and $80 billion at the time of the public listing.
How Wall Street’s biggest names got their slice
Fidelity Investments allocated SpaceX shares across multiple mutual funds, with individual fund allocations ranging between 2.6% and 4.7%. The Contrafund, one of Fidelity’s flagship products, carried a meaningful SpaceX position.
ARK Invest’s innovation-focused ARK Venture Fund held SpaceX at 11.4% of its assets as of the end of March 2026.
The secondary market played a crucial role in enabling this accumulation. Before SpaceX went public, shares traded on secondary platforms where accredited investors and institutional buyers could purchase equity from employees and early shareholders. Specialized funds and special purpose vehicles further broadened access, creating pathways for investors who couldn’t participate in primary funding rounds to gain indirect exposure.
What the SpaceX playbook means for private markets
Baron Capital’s trajectory with SpaceX illustrates the shift in private market investing. The firm’s $2 billion investment grew to $12 billion while SpaceX was still private. By the time retail investors could buy shares on Nasdaq, much of the wealth creation had already occurred.
This dynamic has pushed mutual funds, ETFs, and other traditionally public-market vehicles to find ways into private companies. Fidelity’s multi-fund SpaceX allocation and ARK’s venture fund are symptoms of this broader trend.
The risk profile of this approach deserves attention. When SpaceX made up a third of Baron Partners Fund, investors in that fund were essentially making a concentrated bet on a single company that couldn’t be easily sold.
