April 2 (Reuters) - Elon Musk's SpaceX boosted its target IPO valuation above $2 trillion, Bloomberg News reported on Thursday, citing people familiar with the matter, setting the stage for what could become the largest stock market listing on record.

SpaceX and its advisers are floating the figure to prospective investors in its initial public offering, Bloomberg News reported.

Deliberations are ongoing and details of the IPO could still change, according to Bloomberg News.

The company did not immediately respond to a Reuters request for comment.

SpaceX, based in Starbase, Texas, submitted confidential IPO paperwork with the U.S. Securities and Exchange Commission recently and is targeting a market launch later this year.

The IPO comes after Musk merged SpaceX with artificial intelligence startup xAI in a deal that valued the rocket company at $1 trillion and the developer of the Grok chatbot at $250 billion.
