Three of the most consequential private tech firms are preparing for a historic convergence in public markets. SpaceX, OpenAI, and Anthropic are each targeting initial public offerings that could collectively inject nearly $3 trillion in market capitalization into exchanges.
SpaceX leads the charge. Elon Musk’s rocket company filed confidential S-1 paperwork with the SEC in April 2026, aiming for a Nasdaq listing under ticker SPCX. The valuation target sits between $1.75 trillion and $2 trillion, with proceeds expected to range from $50 billion to $75 billion.
The AI giants follow closely behind. Anthropic, led by Dario Amodei, filed its IPO paperwork around June 1, 2026. Valued at approximately $965 billion in its last private round, it targets a Q4 2026 debut. Sam Altman’s OpenAI, valued at $852 billion, is eyeing a September 2026 listing as it transitions from nonprofit governance to a for-profit structure capable of supporting public investors.
These valuations dwarf historical precedents like Facebook’s 2012 IPO. While none of these entities have direct ties to digital assets, their scale represents a fundamental shift in public market dynamics. All listings remain subject to SEC review and prevailing market conditions.
