SpaceX Files for $1.75T IPO Tied to xAI Merger

SpaceX filed its S-1 and listed shares at $1.75 trillion after absorbing xAI earlier in 2025. The prospectus disclosed that space tourism and human augmentation markets do not yet exist and that the combined entity would remain unprofitable without the xAI revenue projection. Starlink and NASA contracts continue to generate cash, yet the filing shows those segments account for under 20 percent of the modeled total addressable market.

Public filings and subsequent trading data reveal that shares fell sharply after the debut. Volume spiked on opening day then declined as institutional buyers reduced positions once lock-up provisions and dilution schedules became clear. Off-balance-sheet vehicles noted in the risk section mirror structures used by other hyperscalers to fund data-center builds, yet no performance metrics for those vehicles were supplied.

The episode demonstrates that detailed risk language did not constrain demand when capital was available at scale. Secondary-market prices have since tested levels below the IPO range, confirming that disclosure alone did not prevent initial mispricing. Operational focus now shifts to whether xAI can convert projected AI service revenue into reported earnings before further equity raises are required.
