SpaceX's $75bn IPO makes Musk the world's first trillionaire and hands him an acquisition war chest

SpaceX opened on Nasdaq at $150 per share, roughly 11% above its IPO price, and closed day one near $161, generating approximately $75 billion in proceeds and pushing Musk's net worth past the trillion-dollar mark across SpaceX, Tesla, and other holdings. The roll-up framing now circulating on Wall Street is not just rhetorical: Musk has already deployed capital into a reported $60 billion acquisition of AI coding tool Cursor, with SpaceX's stated plans to build satellite-connected in-orbit data centres creating a vertical logic that links space infrastructure to AI compute. SpaceX is currently loss-making, and the investment case is explicitly a long-duration bet on execution rather than current earnings. The more structural concern for competitors is that Musk now holds public-market equity at scale as acquisition currency, a position no other AI or aerospace founder currently occupies. UK institutional investors with mandates to access US tech growth should expect this to be a heavy index inclusion conversation within weeks.
