ARK Invest Buys 3.29M SpaceX Shares on $75B IPO, Sells $222.9M in Stocks
ARKK•ARK Invest acquired 3.29 million SpaceX shares across four ETFs on its $75 billion IPO day, making SpaceX the top holding in ARKX at 6.89%. The firm simultaneously sold roughly $222.9 million of 20 stocks, including trimming Rocket Lab positions in ARKQ and ARKX to free capital.
1. SpaceX IPO Investment
On its Nasdaq debut, SpaceX raised $75 billion by selling 555.6 million shares, marking the largest public market debut ever. ARK Invest purchased 3,291,184 of those shares across ARKK, ARKQ, ARKW and ARKX, with the largest position in ARKX representing 6.89% of that ETF’s assets.
2. Rocket Lab and Portfolio Sales
To fund the SpaceX acquisition, ARK Invest sold roughly $222.9 million of shares in 20 companies. Among the disposals was a reduction of Rocket Lab positions in ARKQ and ARKX, following SpaceX’s description of Rocket Lab as a competitor in both small- and medium-lift launch markets.
3. Strategic Rationale
ARK Invest’s thesis highlights SpaceX’s reusable rockets driving structurally lower launch costs versus competitors. This strategic rotation underscores ARK’s focus on high-conviction, disruptive innovation leaders within its ETFs.
