SpaceX’s initial public offering has attracted demand for more than four times the available shares, according to people familiar with the matter, ahead of the Elon Musk-led rocket, satellite and artificial intelligence firm stopping taking orders.

The banks are expected to stop taking orders from institutional investors after the market closes in New York at 4 p.m. on Wednesday, people familiar with the matter have said.

SpaceX’s IPO is set to price June 11 and trade the following day. The company is offering 555.6 million shares at a fixed price of $135 each, which would raise about $75 billion, and value it at about $1.8 trillion.

Orders are still being taken and details could change, the people said, asking not to be identified as the information isn’t public. A representative for SpaceX didn’t immediately respond to a request for comment.

The IPO is expected to rank as the biggest ever, topping Saudi Aramco’s $29.4 billion debut in 2019. OpenAI, whose AI models compete with those from SpaceX’s xAI business, filed confidentially for a listing on Monday, following Anthropic PBC last week. Together with SpaceX, the three companies could add $3.6 trillion of market value to US exchanges, according to Bloomberg calculations. 

Goldman Sachs Group Inc., Morgan Stanley, Bank of America Corp., Citigroup Inc. and JPMorgan Chase & Co. are leading the deal, with 18 other banks participating. Shares in the company, which is formally known as Space Exploration Technologies Corp. will trade on Nasdaq and Nasdaq Texas under the symbol SPCX.
