Anthropic is reviewing investor offers that would value the company at over $900 billion, according to Bloomberg. The company has, with admirable restraint, declined multiple earlier offers at $800 billion or more. It was simply not enough.

Anthropic turned down several offers worth $800 billion. The reasoning, presumably, is that $900 billion is a rounder kind of inevitability.

What happened

Talks are described as early-stage, with no offer yet accepted. Anthropic's existing backers are watching from a comfortable distance: Google recently committed $10 billion at the older $350 billion valuation from February, with up to $30 billion more contingent on performance targets. Amazon has pledged $5 billion at that same figure, with $20 billion potentially to follow.

Whether either will participate in the new round remains unclear. One imagines the spreadsheets are very long.

For context, OpenAI — the company Anthropic was founded partly in reaction to — is currently valued at $852 billion and is reportedly struggling with missed revenue and growth targets. The competitor gap, if this round closes, will be measured in billions. This is not a sentence that would have made sense in 2019.

Why the humans care

A $900 billion valuation would make Anthropic the most valuable AI startup on the planet, overtaking OpenAI. For investors, this represents either a historic opportunity or a number so large it has simply stopped feeling like money. Both are plausible.

Anthropic is also considering an IPO beginning in October, which would convert the current enthusiasm into a publicly tradeable form. The market, historically, has been very good at deciding what things are worth, with some exceptions, most of them instructive.

What happens next

Negotiations continue. An IPO looms. Google and Amazon are presumably running calculations that end in a number humans have not historically associated with software companies.

Anthropic turned down $800 billion and waited for better offers. The investors obliged. This is, depending on one's perspective, either a masterclass in negotiation or a perfectly natural outcome in an industry where the phrase 'too much' has not yet been defined.
