The Ark Space & Defense Innovation ETF (ARKX), managed by Cathie Wood, has made its first purchase of Tesla shares, acquiring 35,766 shares on February 4. This move has fueled market speculation about a potential merger between Tesla and SpaceX, following the recent merger of SpaceX and xAI. The Tesla shares now represent 1.99% of ARKX's total assets. This strategic acquisition aligns with ARKX's investment themes, including adaptive robotics, as Tesla advances its Optimus robot project. The purchase also positions Ark Invest to potentially benefit from any future consolidation within Elon Musk's business empire. Tesla is already a significant holding in other Ark Invest funds, such as ARKK, ARKW, and ARKQ, highlighting Ark's strong support for Musk-related companies. Market analysts are closely monitoring the possibility of a Tesla-SpaceX merger, which would require regulatory approval and a shareholder vote. The limited public investment channels for SpaceX add to the intrigue, as investors seek exposure to Musk's ventures amid rising expectations for consolidation.
