SpaceX Occupies Top, High-Conviction Holding in RONB ETF

The article highlights Baron Capital’s strong conviction in SpaceX and how that conviction is reflected in Baron First Principles ETF (RONB), which held a 31.7% allocation to SpaceX as of July 15, 2026. The piece argues that SpaceX’s reusable rocket technology, autonomous landings, and vertically integrated model are driving down launch costs while expanding demand for space access. It also emphasizes Starlink as a second growth engine that benefits from SpaceX’s launch capabilities, potentially strengthening the company’s long-term growth profile. For investors, the main market implication is that RONB is highly concentrated and offers outsized exposure to SpaceX’s execution and growth, making the ETF a high-conviction, high-risk vehicle tied closely to the aerospace/space economy theme.
