Juan Hernandez, a former SpaceX employee who owns 6,500 company shares, could see his wealth balloon by as much as $880,000.

SpaceX's IPO could value the company at $1.8 trillion, raise $75 billion, and create 4,000 new millionaires including cafeteria workers with stock options.

The stock market debut of Elon Musk's AI and space company could make thousands of SpaceX employees significantly wealthier, including some of the firm's lowest-paid staff.
