Tens of thousands of retail Australian investors are about to find out how many shares they've been allocated in the world's biggest-ever initial public offering.
SpaceX will go public on the US Nasdaq exchange on Friday, with its listing set to raise up to $US75 billion ($A106 billion) to advance Elon Musk's grandiose vision of making human life multi-planetary.
In a rare and perhaps unprecedented move, retail investors in Australia, Europe, the UK and several other countries outside the US were granted access to the red-hot initial public offering (IPO).
CommSec, the lead Australian broker for the transaction, was warning of "extremely high call volumes" earlier this week and advising customers to submit their applications online.
"We've seen very good interest across a broad, broad range of Australian investors," a source familiar with the transaction but not authorised to speak publicly told AAP.
