Not Space. Not Starlink. Here's My Top Reason to Buy SpaceX Stock.

While SpaceX is renowned for its groundbreaking rocket launches and reusable technology, it may not be the most compelling reason to invest in its stock. The company's Starlink broadband service, a satellite-based internet provider reaching users worldwide, is another notable achievement. However, according to the source, the most promising aspect of SpaceX's growth is its super intelligence (SI) division, which focuses on AI and data center platforms.

This division, previously known as xAI, experienced an astonishing 830% year-over-year revenue growth, reaching $7.56 billion in the third quarter of 2026. Notably, AI services, led by the Grok family of large language models and products, are gaining traction in both business and personal domains, driving SpaceX's rapid expansion.

The SI division's capital expenditures of $16.4 billion in Q3 2026 further reinforce its commitment to this sector. Despite a $1.2 billion stock-based compensation cost from the recent Cursor acquisition, SI still managed to generate a modest operating profit of $431 million, marking it as a promising investment prospect. If the SI division's growth continues, SpaceX's stock may be more appropriately viewed through an AI lens rather than solely a space technology perspective.
