Elon Musk's SpaceX is planning to set a fixed price of $135 per share ahead of officially

marketing its initial public offering. A person familiar with the matter told us today, I'm told

that we'll be made official in an amended filing after the bell. Typically at this stage of the

process, new issuers will offer a price range that allows a company and its advisors to gauge demand sensitivity at different levels.

But in this case, SpaceX took a unique approach after a slew of testing the Waters' meetings leading up to the Rocho launch.

The company plans to sell 555.6 million shares, implying a $75 billion offering size, according to the person who spoke on the condition of anonymity because the details are still private.

At the $135 per share price tag, though, SpaceX would be valued at $1.75 trillion, which assumes the Echo Star Spectrum and cursor transactions close.

Reuters earlier reported the pricing details.

I'm told the fixed price was chosen in lieu of a range due to the depth of the testing

the waters process in recent weeks that involved conversations with institutional investors

who indicated enough demand existed at that $135 per share level.

Retail investors who are expected to comprise about 30% of the IPO are still more of a

wild card at this stage, but tend to be less price sensitive and have decades-long track

record of following Elon Musk.

Advisors will be able to obtain more feedback from that cohort when the roadshow does kick

off beginning tomorrow morning.

Musk's company is planning on debuting at the NASDAQ on June 12th next Friday.

SpaceX, which will go public under the ticker symbol SPCX, is said to be the biggest

IPO ever more than triple the size of Alibaba,

which is the biggest US IPO today.

That won $25 billion.

Carl, feels like just yesterday we covered that.
