Step 1 : Introduction to the question "After SpaceX began trading on the stock market last week, Elon Musk’s net worth shot to how many figures?"
...It’s 13 figures — a trillion dollars, represented by a one followed by 12 zeros. Elon Musk, the chief executive and largest shareholder of SpaceX, became the world's first trillionaire when the company went public at $150 per share. The record-breaking IPO and subsequent surge in SpaceX's stock price pushed Musk's estimated net worth above the $1 trillion mark, a milestone never before reached by an individual. The dramatic increase was fueled primarily by the value of his SpaceX holdings, along with his substantial stake in Tesla.
