ARKX ETF offers diversified way to invest in orbital economy

Investors seeking exposure to the orbital economy can use ARK Invest’s Space Exploration & Innovation ETF (ARKX), which holds SpaceX as its largest position at a 7.2% weighting and spreads capital across other aerospace and semiconductor names.

SpaceX shares trade well above their IPO price of $135 and command a market valuation above $2.4 trillion. The company has not reported profitability, so price-to-earnings measures do not apply; its price-to-sales ratio is near 130 times.

ARKX pairs SpaceX with other holdings including Rocket Lab, which sits at about 6.8%, and aerospace and component suppliers such as L3Harris and Advanced Micro Devices. The fund manages roughly $1.1 billion in net assets and charges an expense ratio of 0.75%.

Industry forecasts cited by market research firm Global Market Insights put the global space economy at $439 billion last year, project it at $462 billion in 2026 and estimate it could reach $851.8 billion by 2035. ARKX’s holdings span launch providers, satellite manufacturers, communications infrastructure and specialty semiconductors.

SpaceX has achieved several early milestones in its history, including a 2008 liquid-fueled orbital launch and a 2012 docking with the International Space Station. Investors considering direct exposure to SpaceX face concentrated company risk and valuation risk tied to the firm’s high multiple and lack of reported profits.

The ETF structure reduces single-stock concentration by allocating smaller positions to multiple companies across the aerospace value chain. The fund does not remove sector risk; aerospace companies remain sensitive to government spending cycles, supply-chain disruptions and launch failures.

Investors choosing between a single-stock position in SpaceX and a stake in ARKX face trade-offs. A direct stake concentrates upside and downside in one company. A stake in ARKX distributes exposure among launchers, contractors and component suppliers, creating a broader portfolio link to growth in the orbital economy.
