SpaceX revealed its long-awaited plans to go public on Wednesday, shedding light on the finances and leadership of one of the largest, best-known and yet most secretive private companies in history.

The space and AI company’s initial public offering could be valued as high as $2 trillion, which would be the biggest IPO ever.

It would likely be the biggest IPO ever, surpassing the 2020 debut of Saudi Aramco.
