Elon Musk, CEO of Tesla Inc (NASDAQ:TSLA), secured a $1 billion loan from SpaceX, his own company, around the time he was acquiring social media company X (formerly known as Twitter). The loan, backed by Musk's SpaceX stocks, was approved and drawn down completely in October and promptly repaid in November. The exact reasoning behind this debt acquisition remains unclear. This borrowing occurred amidst significant investments by SpaceX in its Starship rocket program and the Starlink satellite-internet business.
