SpaceX: IPO Raises Approximately $85.7 Billion as Underwriters Fully Exercise Overallotment Option
Claire Weston
SpaceX completed its IPO on June 15, raising approximately $85.7 billion after underwriters exercised the full overallotment option — one of the largest public offerings on record, with proceeds earmarked for AI compute, launch infrastructure, and satellite constellation expansion.
How much did this IPO actually raise?
SpaceX issued a total of 638,888,888 Class A shares, bringing gross proceeds to approximately $85.7 billion.
Underwriters exercised their full greenshoe — an option that lets them sell extra shares when demand is strong — adding 83,333,333 shares, or roughly 15% above the base offering.
This means → investor appetite was so strong that the banks used every share they were allowed to sell.
Where and when did trading begin?
Class A shares started trading on June 12 on the Nasdaq Global Select Market and Nasdaq Texas, under the ticker SPCX.
All shares settled on June 15. In plain terms = money and stock have changed hands, and the IPO process is officially complete.
What will SpaceX do with the money?
The company disclosed four main uses: expanding AI compute infrastructure, strengthening launch facilities and rockets, scaling its satellite constellation, and general corporate purposes.
This reflects a strategy that goes well beyond rocketry — AI compute is listed first, signaling SpaceX is positioning itself as a dual-track space-plus-compute platform.
Who underwrote the deal?
The book-running managers — the core team that priced and allocated shares — include Goldman Sachs, Morgan Stanley, BofA Securities, Citi, and J.P. Morgan, alongside Barclays, Deutsche Bank Securities, RBC Capital Markets, UBS Investment Bank, and Wells Fargo Securities.
Another 12 co-managers rounded out the syndicate, including Cantor, Needham, Raymond James, Société Générale, Macquarie Capital, Mirae Asset Securities, Mizuho, and Santander.
This means → virtually every top-tier investment bank participated, and the sheer breadth of the syndicate speaks to the scale and market significance of this offering.
