Cathie Wood’s Ark Invest bought 3.3 million SpaceX shares on its IPO day

ARK Invest bought nearly 3.3 million shares of SpaceX (SPCX) as Elon Musk’s company went public in the largest IPO ever on Friday, building a stake worth more than $500 million by the end of the day.

The shares, priced at $135 for the sale, closed at $160.95, rising more than 19.2% on their first day.

The Cathie Wood-owned firm liquidated almost $280 million of stock in the week before the listing, then sold another roughly 948,000 shares across 13 companies worth at least $48 million on Friday, including Advanced Micro Devices, Roku and Baidu, according to daily emailed statements over the period.

The ARK Innovation ETF (ARKK) did the bulk of the buying, ending the day with SpaceX at 3.28% of its portfolio.

A first-day pop of almost 20% on the largest IPO in history signals institutions are paying up for high-beta innovation risk again. While bitcoin is the highest-beta asset in the group, the hottest trade in the market is now a wave of AI and space listings, with OpenAI and Anthropic also filing to go public.
