Cathie Wood's Ark Bought $27 Million of SpaceX Stock. Here's Whether You Should Follow Her Lead.

Cathie Wood's Ark Invest has expanded its stake in Space Exploration Technologies (SPCX.OQ), purchasing 200,000 shares across several ETFs for approximately $27 million during recent share price weakness. The transaction solidifies SpaceX as Ark's second-largest position, valued at roughly $680 million, trailing only Tesla in the firm's portfolio. The investment thesis aligns closely with Ark's broader focus on artificial intelligence and autonomous infrastructure. Ark models SpaceX to potentially generate $300 billion in annual revenue once its Starlink constellation reaches completion around 2035. Cash flows from Starlink are expected to fund orbital data centers capable of reducing AI compute costs by approximately 25% relative to terrestrial infrastructure. SpaceX shares traded around $141.50 following the purchase, remaining comfortably above their $135 IPO price. The firm's long-term market valuation increasingly hinges on execution across speculative AI computing opportunities, which SpaceX estimates comprise over 90% of its $28.5 trillion total addressable market.
