OpenAI, SpaceX, and Anthropic are preparing for trillion-dollar IPOs that could reshape public markets

The three most consequential private companies in tech are all heading for the public markets at roughly the same time. SpaceX, OpenAI, and Anthropic are each preparing IPOs with valuations that would have seemed absurd five years ago and now seem almost inevitable.

Together, these three listings could inject close to $3 trillion in market capitalization into public exchanges.

SpaceX leads the charge

Elon Musk’s rocket company filed its confidential S-1 paperwork with the SEC back in April 2026, targeting a Nasdaq listing under the ticker SPCX. The company is aiming for a valuation between $1.75 trillion and $2 trillion, which would make it one of the most valuable companies on the planet from day one.

SpaceX expects to raise between $50 billion and $75 billion through the offering.

The AI giants follow close behind

Anthropic, the AI safety company led by Dario Amodei, confidentially filed its own IPO paperwork around June 1, 2026. The company’s most recent private funding round valued it at approximately $965 billion, and it’s targeting a Q4 2026 debut that would likely push it past the trillion-dollar mark.

Sam Altman’s OpenAI is also positioning for a public listing. The company’s latest private valuation sits at $852 billion, with a target IPO valuation of around $1 trillion. OpenAI is eyeing a listing as early as September 2026, though the timeline could stretch into early 2027.

OpenAI’s path to public markets has been particularly complicated. The company has been navigating an internal restructuring that involves transitioning from its original nonprofit governance structure to a for-profit entity capable of supporting public investors.

What this means for investors

The closest historical comparison might be the 2012 Facebook IPO, which was valued at roughly $104 billion. These companies are entering public markets at valuations that are 10 to 20 times larger.

For crypto markets specifically, none of these companies have any direct connection to digital assets or blockchain technology.

All three IPOs remain subject to SEC review and prevailing market conditions. The timelines are targets, not guarantees.
