Elon Musk Owns 20% of Tesla, a Stake Worth Roughly $200 Billion. Here's Why His Ownership Level Matters for Shareholders.

The article argues that Elon Musk’s unusually large ownership and voting influence over Tesla materially affects the investment case. Musk owned roughly 20% of Tesla at the end of 2025, including more than 300 million options he exercised, while Vanguard was the next-largest holder at 6.1%. The piece says insider ownership can be positive because it aligns management and shareholder interests, but at Tesla’s scale Musk’s control may also overpower other shareholders and the board. It highlights that Musk also has 82% voting control at SpaceX, reinforcing the point that investors are effectively betting alongside him. The market takeaway is that Tesla’s stock is not just a bet on EV fundamentals; it is also a bet on Musk’s decisions, which the article suggests can be both visionary and risky. The article notes that Musk’s political activity in 2025 contributed to a boycott and materially weaker deliveries, underscoring governance and key-person risk.
