Space ETF ARKX surges 4.6% as sector rally reignites investor interest

The ARK Space Exploration & Innovation ETF surged as much as 4.6% on June 29, extending a sector-wide rally in space-related equities.

"The space economy is broadening beyond launch providers into a full supply chain story," said Priya Mehta, equity market analyst at Edgen. "ARKX gives investors diversified exposure to that theme without single-stock concentration risk."

The $893 million fund, which holds 35 positions spanning launch providers, defense contractors and chipmakers, has returned 46.71% over the past year. Its top holdings include L3Harris Technologies at 7.83% of net assets and Rocket Lab at 7.78%. Rocket Lab has surged 190.18% over the past 12 months, while L3Harris added 18.86% in the same period.

The rally comes as SpaceX's publicly traded tracking stock, SPCX, stabilized after a three-day selloff erased 24% from its post-IPO peak. ARK Invest bought 210,121 SPCX shares across four ETFs on Monday, including 131,837 shares through its flagship ARK Innovation ETF, betting on a rebound in the world's most valuable space company.

SpaceX's volatile debut underscores the appeal of diversified exposure

SpaceX priced its IPO at $135 per share in the largest public market debut in history, raising $75 billion. The stock surged to nearly $220 before retreating to $154.6, a swing that Mohamed El-Erian, chief economic advisor at Allianz, called "Wild!" on X. With only about 4% of shares available for trading, the float remains thin, leaving concentrated holders exposed to sharp drawdowns.

ARKX spreads the space bet across the full value chain. Beyond Rocket Lab and L3Harris, the fund owns stakes in satellite communications companies, defense electronics firms and semiconductor suppliers that power orbital computing. The approach has insulated the fund from single-stock volatility: when Rocket Lab dropped 30% earlier this year, L3Harris limited ARKX's decline to just 7%.

The broader market backdrop has also shifted in favor of innovation-led equities. Cathie Wood, ARK Invest's chief executive, has argued that the bond market is discounting the deflationary impact of artificial intelligence rather than inflation risks, a dynamic she says could create "a remarkably supportive backdrop for innovation-led equities." The ARK Innovation ETF gained 35.49% in 2025, far outpacing the S&P 500's 17.88% return, though it has slipped 1.48% year to date against the S&P 500's 7.49% gain.
