Musk invests $1.4 billion to increase his stake in SpaceX, further consolidating his control.

Elon Musk purchased $1.4 billion worth of company stocks from current and former employees of SpaceX last year, increasing his personal stake in the company. These series of actions are all part of the company's strategy before its initial public offering, aimed at strengthening his control over the enterprise. The large-scale secondary market stock purchase was completed by the billionaire's family trust, and the relevant information was disclosed in the SpaceX confidential IPO prospectus. The document also revealed a new stock incentive plan: if SpaceX's market value reaches trillions of dollars, Musk will be granted tens of millions of shares. It is currently unclear what valuation Musk's stock purchase corresponds to.
