Elon Musk鈥檚 SpaceX has set a target share price of $135 (拢101) and added an option to expand its capital raise from $75bn to $86bn, taking its initial public offering market value to almost $1.8tn. The previous valuation of $1.75tn would already have made the float the largest ever.
SpaceX鈥檚 publication of its prospectus last month both captured investor attention and also raised worries given its sky-high valuation, loss-making businesses, and lack of shareholder rights. Through supervoting B shares, Musk has control of the board through 85 per cent voting power. Given the company鈥檚 quick entry to the Nasdaq and potential entry into the S&P 500 within a few months, investors globally will be exposed to SpaceX through tracker funds.
Analysts have also pointed to a potential merger between SpaceX, which includes a rocket business, social media platform X, internet provider Starlink, and xAI, and Musk鈥檚 car company Tesla (US:TSLA). Using SpaceX鈥檚 pre-IPO valuation of $1.75tn and Tesla鈥檚 market value, this would create a $3tn company that posted a net loss of $1.1bn in 2025 (combining Tesla鈥檚 net income of $3.8bn with SpaceX鈥檚 net loss of $4.9bn).
