Cathie Wood's ARK Buys ~$530M of SpaceX on IPO Day

Cathie Wood's ARK Invest went all-in on the SpaceX debut, buying roughly half a billion dollars of stock across four ETFs on the same day the rocket company hit the Nasdaq. Everything else got trimmed.

The trade

SPCX was the only buy on the tape for ARK on Friday. The firm purchased a combined 3,291,184 shares of SpaceX across the ARK Innovation ETF (ARKK), ARK Autonomous Technology & Robotics ETF (ARKQ), ARK Next Generation Internet ETF (ARKW), and ARK Space Exploration & Innovation ETF (ARKX).

SpaceX closed Friday at $160.95 per share, pushing ARK's total investment to more than $529 million across its four ETFs. Every other position movement on the day was a sell.

The IPO that broke the record book

The SpaceX IPO raised $75 billion from the sale of 555.6 million shares, making it the largest public market debut in history. That tops Saudi Aramco's prior record.

Shares opened at $172 for a 27.4% gain over the $135 offer price, finished the regular session up 19.22% at $160.95, and tacked on another 3.37% to $166.37 in extended trading.

What ARK sold to make room

The buy did not happen in a vacuum. ARK offloaded shares in 20 companies on Thursday, selling roughly $222.87 million across its ETFs on the eve of the SpaceX IPO.

On Friday itself, Wood's firm sold stakes in Musk's own Tesla, along with Roku, AMD, Rocket Lab, Cloudflare, and CrowdStrike, among others. Selling Tesla to fund a SpaceX buy on Musk IPO day is the punchline.

Why it matters

ARK has been building SpaceX exposure for years through its private Venture Fund, and the public IPO finally gives the flagship ETFs a liquid way to own the name. ARK first invested in SpaceX in late 2023 at a sub-$200 billion valuation and has been adding incrementally since, including after the SpaceX-xAI merger in 2026.

SpaceX is now valued at roughly $2.11 trillion, a level that reportedly made Elon Musk the first trillionaire in the world.

Options market and stocks to watch

Watch SPCX for post-IPO flow as lockup chatter and ETF rebalancing dominate the tape in the coming weeks.

Watch ARKK, ARKQ, ARKW, and ARKX for concentration risk, as SpaceX instantly becomes a top holding across all four funds.

Watch TSLA for follow-through selling pressure after ARK trimmed alongside the SpaceX buy, and RKLB as the closest public comp facing a new mega-cap competitor on the tape. More market news here.
