NEW YORK — Elon Musk's SpaceX began its first day as a public company on Wall Street on Friday after the biggest initial public offering in history, with the polarizing entrepreneur promising he will take humanity to Mars.

The blockbuster operation, which raised more than $75 billion, is expected to make Musk the world's first trillionaire and kick off a series of major IPOs by AI companies in the coming months.

The first trades — and the level of demand — were expected to be confirmed shortly after the opening of the Nasdaq market in New York.

"SpaceX wants to be able to take you to the moon, take you to Mars, and ultimately beyond," Musk said at a launch event in Starbase, Texas, surrounded by staff members.
