SpaceX is seeking to file publicly for its long-awaited IPO as soon as Wednesday, according to people familiar with the matter.

Elon Musk’s rocket, satellite and artificial intelligence company aims to kick off formal marketing as soon as June 4, price its initial public offering as early as June 11 and list on June 12, one of the people said, asking not to be identified as the information isn’t public.

Details of the IPO including the size and timing could still change, the people said. A representative for SpaceX didn’t immediately respond to a request for comment.

The company has picked Nasdaq for its IPO and will list under the ticker SPCX, Reuters reported earlier Friday, citing people it didn’t identify. The news agency was first to report the new timeline. Nasdaq declined to comment.

SpaceX has filed confidentially to go public and is seeking to raise as much as $75 billion at a valuation of more than $2 trillion, Bloomberg News has reported, which would be the largest IPO of all time.
