With unicorns so lousy around the place like they’re pigeons in Central Park, it’s time to consider a new class of company: let’s talk hectocorns, or private companies worth at least $100 billion. Right now, there are three of them:

• SpaceX, the American rocket ship company, currently valued at $350 billion;
• OpenAI, the closest that the emerging AI industry has to a blue chip, valued at $300 billion per CB Insights;
• ByteDance, the TikTok owner, a Chinese company also valued at $300 billion;

And potentially joining the club, as the Financial Times reports it’s looking to fundraise with eyes toward a $113 billion market cap, is xAI, Elon Musk’s AI venture.
