April 22 (Reuters) - Elon Musk's rocket and satellite company SpaceX is targeting a valuation of $1.75 trillion when it goes public, which could instantly make it one of the biggest companies in the world.

SpaceX was last valued at $1 trillion after the company acquired artificial-intelligence startup xAI in February. The transaction valued xAI at $250 billion, Reuters reported.

ChatGPT-parent OpenAI and Anthropic are also reportedly racing to an IPO later this year.
