Elon Musk, CEO of privately held SpaceX, secured $500 million in loans from the rocket company over three years, with interest rates as low as 1%—far below public company lending standards. These transactions, enabled by SpaceX's private status, allowed Musk to fund struggling ventures like Tesla, SolarCity, and xAI, creating conflicts of interest. Some investors, including Founders Fund, expressed concerns about prioritizing Musk's interests over shareholders, a risk highlighted by law professor Ann Lipton.

SpaceX, valued at $1 trillion, has become a critical financial tool for Musk, who owns about 40% of the firm. The company's success, bolstered by Starlink contracts and Mars ambitions, made it a key player in Musk's empire. Now preparing for a potential mega IPO, SpaceX will face scrutiny over its dealings with Musk.

This pattern—seen in Tesla's disclosed loans—underscores how privately held companies can enable complex corporate maneuvering.
