‘Hectocorns’ Are Just One AI Flashpoint for 2026

They’re calling them the “hectocorns,” apparently: artificial intelligence startups valued at $100 billion or more. I’m old enough to remember when being a “unicorn,” worth a measly $1 billion, was a milestone to be intensely proud of. Simpler times.

In 2026, AI hectacorns might go public. That process, historians would tell you, was a harbinger for the dot-com bust as hopeless balance sheets were ignored in favor of overhyped promises that eventually collapsed. Will the A-IPOs prove to be a similar come-to-Jesus moment? It’s one theme I’ll be watching closely in 2026, but it’s certainly not the only one.

The A-IPOs are coming (maybe)

I was feeling a little sheepish earlier this year when, three months after my piece warning that CoreWeave Inc.’s IPO would air AI’s “dirty laundry” financials, the company’s stock had quadrupled its $40 IPO share price.

But then, as the demands of quarterly earnings reports kicked in, investors became nervous about its debt load and delays in building data centers. Short sellers lurked. As one of the relatively few pure-play AI stocks, CoreWeave feels every bump on the the AI boom road. Its stock is now down about 53% from that steamy summer peak.

Whether other AI companies considering going public should take much from CoreWeave’s experience is a complex question. Two contenders, Anthropic and OpenAI, are synonymous with the AI boom and would therefore feel the brunt of the market’s optimism or pessimism on any given day. But, unlike CoreWeave, they exist in a different part of the AI “stack” — they are not a pick or shovel but the theoretical gold.

A-IPO

Preparations are being made for some huge listings, though whether they will take place in 2026 isn’t clear. Anthropic, the FT reported in early December, has consulted IPO lawyers ahead of a potential listing. It is securing a private funding round, the newspaper said, that would value it at somewhere between $300 billion and $350 billion. OpenAI, meanwhile, is said to be lining up a new funding round that could propel its valuation to $750 billion.

Both companies are clearly still confident they can raise money privately. This makes a listing, with all the scrutiny of required disclosures and quarterly earnings calls, a not-altogether-appealing option. “Am I excited to be a public company CEO? Zero percent,” Chief Executive Officer Sam Altman remarked on recent podcast. “Am I excited for OpenAI to be a public company? In some ways I am, and in some ways I think it would be really annoying.”

And yet there may be additional riches to be had by being the first to pull the trigger. And riches are what matters in the scramble to stay ahead.
