Cathie Wood’s ARK Invest moved quickly into SpaceX on its first day as a public company, building a position worth more than $500 million as the stock delivered the largest IPO debut on record. The purchase followed a wave of internal portfolio changes that reshaped exposure across technology, crypto, and high-growth sectors.
Trading disclosures show that ARK acquired roughly 3.3 million shares on June 12, the day SpaceX began trading. The company priced its IPO at $135 per share and closed at $160.95, a gain of more than 19%. Intraday trading pushed the stock as high as $176.52. The debut placed SpaceX among the largest public companies in the United States, with a market capitalization above $2.1 trillion.

The ARK Innovation ETF carried most of the allocation. By the end of the session, SpaceX represented 3.28% of the fund’s portfolio. The position also ranked as the largest holding inside the ARK Venture Fund, where it accounted for more than 11% of net asset value based on recent filings.
Capital rotation reshapes portfolio exposure
The SpaceX allocation did not occur in isolation. ARK sold large positions across multiple sectors in the days leading up to the IPO. Weekly disclosures show about $280 million in stock sales before the listing. On the same day as the IPO, the firm sold nearly 948,000 shares across 13 companies, raising at least $48 million.
The reductions covered semiconductor, streaming, and internet companies. ARK sold around 80,000 shares of Advanced Micro Devices for about $39.3 million. It also reduced positions in Tesla, Baidu, and Roku, along with smaller sales across CrowdStrike, Cloudflare, Veracyte, and others. The firm exited roughly 50,700 shares of Rocket Lab, a company SpaceX listed as a competitor in its S-1 filing.
One day earlier, ARK liquidated positions across 20 companies with a combined value near $223 million. Teradyne accounted for the largest portion of that figure, with sales of about $76.6 million. Additional reductions in Twist Bioscience, Iridium Communications, and Robinhood Markets added more than $60 million.
These transactions created space for the SpaceX allocation inside ETF structures that must maintain liquidity and balance. The ARK Venture Fund, which participated in private placements before the IPO, provided access to shares that were not freely tradable before listing.
Long-term thesis anchored in valuation expectations
ARK has built its SpaceX position over several years. The firm first entered the company in late 2023 when its valuation stood below $200 billion. It added to the position as valuation climbed to $350 billion in 2024 and expanded exposure again after the integration of artificial intelligence company xAI in early 2026.
Internal models from ARK project a base-case enterprise value of $2.5 trillion for SpaceX by 2030. A bull-case estimate reaches $3.1 trillion, while a bear-case scenario places valuation near $1.7 trillion. These projections align closely with the IPO target valuation of about $1.75 trillion.
Cathie Wood has maintained a consistent position on the company’s technological lead. In a recent Fox Business interview, she stated:
"SpaceX is at least a decade ahead of everyone else."
She also described the company as more than a launch provider, citing Starship, Starlink, and the xAI integration as components of a broader infrastructure strategy.
Pressure builds on crypto allocation
The SpaceX purchase has implications beyond equities. ARK remains one of the most visible institutional supporters of Bitcoin and operates a spot Bitcoin exchange-traded fund. The firm has published long-term projections that place Bitcoin valuations above $1 million.
Recent trades suggest a shift in short-term capital allocation. SpaceX purchase may draw funds away from digital assets as ARK reallocates toward public listings tied to artificial intelligence and space technology.
Bitcoin traded near $65,000 during the same period. The asset has shown sensitivity to macro flows and shifts in risk appetite. The emergence of large-scale IPOs in adjacent sectors introduces competition for capital that was previously concentrated in crypto markets.
Concentration risk remains part of strategy
The scale of the SpaceX position introduces concentration risk within ARK’s portfolios. A single holding above 11% in the ARK Venture Fund means that price changes will have a direct effect on net asset value. This structure has defined ARK’s strategy for years, with high-conviction positions in emerging technologies.
The firm’s approach focuses on early access to companies before public listing. SpaceX’s rise from under $200 billion to more than $2 trillion illustrates that model. Public markets now provide continuous price discovery, which can either validate or challenge private valuations.
The IPO raised as much as $75 billion, setting a record for size. The first-day performance indicates strong demand for companies tied to aerospace, satellite infrastructure, and artificial intelligence. Future listings from companies such as OpenAI and Anthropic could extend this trend.
Market tests next phase after debut
The first trading session delivered a clear signal of investor demand for innovation-led growth. The next phase will depend on sustained revenue growth, execution in satellite and launch operations, and integration of AI capabilities.
ARK’s position places it at the center of that test. The firm has committed significant capital and restructured its portfolio to support that bet. The outcome will influence both equity performance and capital flows across adjacent markets, including crypto.
