Anthropic, the artificial intelligence company behind the Claude chatbot, has reached a valuation of roughly $900 billion — a figure that puts it among the most valuable private technology companies in the world.

According to The New York Times, the striking part of the story is the speed. In a piece titled "The $900 Billion Giant: How Anthropic Got So Big, So Fast," the Times frames Anthropic's rise as unusually rapid, with the company swelling to giant scale in a remarkably short span of time.

The valuation arrives against a backdrop of growing investor anticipation that Anthropic will eventually go public. The Motley Fool published a guide headlined "3 Ways to Invest in Anthropic Before It Goes Public," signaling that retail and other investors are already looking for indirect routes into the company while it remains privately held. The framing of both sources points to an expected initial public offering on the horizon, though the company is not yet listed on public markets.

For everyday readers, the appetite to invest "before it goes public" reflects how much excitement — and money — is now concentrated around a handful of leading AI firms.

A $900 billion price tag means investors are betting that Anthropic's technology will generate enormous future value, even though the company is still young. It also raises familiar questions about whether AI valuations have run ahead of the underlying business.

Why it matters: when a company this new is suddenly worth nearly a trillion dollars and circling an IPO, it becomes a bellwether for whether the broader AI boom is built on durable demand or inflated expectations.
