SpaceX Lodges Confidential IPO Paperwork Targeting $1.75 Trillion June Listing

When RCA went public in 1929 its market cap ballooned on hopes of a radio revolution—only to crater a year later; Cisco’s $555 billion peak in 2000 told a similar cautionary tale. SpaceX’s planned record-setting float echoes those moments when markets bankrolled transformative but still-maturing networks. Two deeper trends underlie the filing: (1) the century-long handoff of government-incubated technologies—rocketry, satellite comms, AI—to private investors once network effects become visible, and (2) the entrenchment of founder control via dual-class shares, a structure pioneered by 1920s rail voting trusts and now common among Big Tech. Musk’s dominance, plus $24 billion in past U.S. contracts, raises questions about public subsidization of private empire-building. Yet if Starlink cash flows deliver and orbital data centers materialize, the IPO could normalize off-planet infrastructure as an investable asset, much as canal and railroad bonds quietly underwrote the Industrial Revolution. Over a 100-year horizon, that institutional shift—not the eye-popping valuation—may prove the lasting legacy.
