Anthropic Presses Ahead With IPO As Investors Balk At $1.5 Trillion

Anthropic will set a valuation range this week and could begin trading on Thursday or Friday of next week, according to The Wall Street Journal. The decision lands days after one of Nasdaq's biggest sell-offs and amid a scandal touching a CEO central to the AI boom. Neither event stopped the listing timetable.

The report is the anchor of this story. Everything below rests on the Journal's sourcing, not on documents Anthropic has published. No prospectus figure has been confirmed.

What does the number tell us?

The valuation is the headline. Some institutional investors now push for a price below the $1.5 trillion target discussed as recently as last week. That target was itself considerably below the $2 trillion figure floated a few months ago.

Read the trend, not the level. The ask has fallen from $2 trillion to $1.5 trillion in months. Buyers want it lower still. A $500 billion haircut between two rounds of talk is not a rounding error. It is a quarter of the original number, gone before a single share trades.

Investors will read Anthropic's final valuation as a gauge of the AI boom's strength. That cuts both ways. A strong print revives the narrative. A cut print marks the second downward revision in a quarter.

How does OpenAI's deal compare?

OpenAI, Anthropic's main rival, was reportedly valued at $1.25 trillion last week. It reached that mark after raising $11 billion in fresh capital. It had initially sought $20 billion.

Do the arithmetic. OpenAI closed at 55 percent of its funding goal — $11 billion against $20 billion. Anthropic's current $1.5 trillion target sits 20 percent above OpenAI's reported $1.25 trillion valuation. The gap has narrowed sharply from the $2 trillion era.

The caveat: both figures come from reporting, not filings. Neither company has stated these numbers on the record in a public document cited here.

Why now?

The timing is the puzzle. The Journal notes the IPO comes shortly after one of Nasdaq's biggest sell-offs. It also comes amid revelations that a CEO central to the AI boom had an affair with a suspected Chinese spy.

Anthropic is undeterred, per the report. That confidence has three possible readings:

• Anthropic believes demand for AI exposure outweighs market volatility.
• The company needs public capital on a schedule it cannot easily move.
• Insiders accept a lower valuation rather than delay into worse conditions.

The report does not say which. Nothing in the Journal's account explains why the calendar survived a sell-off and a security scandal in the same window. That silence is itself information.

What is not said?

Three gaps stand out. The report gives no share count, no float size, no exchange confirmation. It names no underwriters. It does not state what Anthropic will do with the proceeds.

The valuation range comes this week, per the Journal. Trading starts Thursday or Friday of next week — or it does not, if the market turns again. Until the range is printed, every number here is a negotiating position.

For enterprise buyers and CIOs watching AI vendor durability, the lesson is simple. A public listing brings disclosure. It also brings a shareholder clock that private rounds never imposed on Anthropic before.
