Thousands of Britons look to have missed out on SpaceX shares in its record-breaking stock market float after orders among retail investors topped $100billion.

Elon Musk’s rockets and AI company last night made history as announced it sold 555.6m shares at $135 each in the largest initial public offering (IPO) of all time.

That raised $75billion and valued SpaceX at $1.77trillion – putting co-founder and boss Musk on course to become the world’s first trillionaire.

Demand for shares far outstripped supply, with retail investors around the world applying for more than $100billion of stock, according to Bloomberg.

That is well above the $15billion to $22.5bn earmarked for individuals rather than institutions.
