Inside Ron Baron’s $66 billion portfolio: A SpaceX problem and a Tesla cushion
Baron Funds’ approach has for long centred on companies that can compound over many years, even if near-term stock moves remain volatile. The biggest holding is SpaceX, which accounts for 34.3% of the portfolio. The position was added as a new holding in Q2 2026. The average buy price is shown at $169.55, while the current price is $143.49, implying a 15.4% decline from the average purchase price.

SpaceX’s weight makes it the most important position in the portfolio by a wide margin. The investment fits Baron’s long-standing preference for founder-led, innovation-heavy companies with large addressable markets. The bet is on the commercialisation of space, satellite internet, launch services and long-term space infrastructure.
Tesla is the second-largest holding, with a 7.3% portfolio weight. The stock remains one of Baron’s biggest winners. The average buy price is listed at $26.05, while the current price is $356.58, showing a gain of 1,269%. Baron Funds increased its Tesla holding by 5% in Q2 2026.
Tesla gives the portfolio exposure to electric vehicles, energy storage and autonomy-related technology. The holding also shows Baron’s willingness to stay invested in high-growth companies through long periods of volatility. The large gain in Tesla helps offset pressure from newer or weaker positions.
MSCI is the third-largest holding, with a 2.9% portfolio weight. Baron Funds increased the MSCI position by 19% in Q2 2026. The average buy price is $144, compared with the current price of $544.60, implying a gain of 278.2%.MSCI is a different kind of growth bet. Unlike Tesla or SpaceX, it is a financial infrastructure company. Its business is built around indices, analytics and data services used by investors and institutions. This makes it a recurring-revenue play tied to the long-term growth of global investing, passive funds and portfolio analytics.
Arch Capital is the fourth-largest holding, with a 2.5% portfolio weight. The stock has also been a strong performer for the fund. Its average buy price is $16.78, while the current price is $97.04, showing a gain of 478.3%. Baron Funds sold 5% of its Arch Capital shares in Q2 2026.
The reduction suggests some profit-taking after a large gain. Arch Capital gives the portfolio exposure to property and casualty insurance, a sector that can benefit from pricing discipline, underwriting strength and capital allocation over the long term.
Gartner is the fifth-largest holding, with a 2.4% portfolio weight. Baron Funds increased its holding by 28.4% in Q2 2026. The average buy price is $95, compared with the current price of $195.62, showing a gain of 105.9%.
Gartner’s business is linked to research, advisory and data services for enterprises. The position fits the broader portfolio pattern: asset-light companies with strong client relationships, pricing power and recurring demand.
The next set of holdings also points to the same theme. Shopify, Spotify, Guidewire Software, Charles Schwab and Hyatt Hotels are among other major positions. Baron Funds sharply increased Shopify shares by 136.4% in Q2 2026, while Spotify was increased by 84.4% and Charles Schwab by 56.2%.
Overall, the investor has 321 stock positions. By industry exposure, the largest buckets include industrials at $21.2 billion, manufacturing at $11.6 billion, information at $10 billion and finance and insurance at $8.82 billion.
The portfolio is not a low-risk basket. A 34.3% weight in SpaceX means a large part of the portfolio is tied to one private-market-linked growth story. But the top holdings also show why Baron’s style has worked in some cases, that is the fund is willing to hold companies for long periods when it believes the business can become much larger.
