Anthropic IPO Valuation Slides Toward 1 Trillion USD: What Investors Want Before the Listing

The Anthropic IPO valuation is under pressure. After the sharp drop in tech stocks on 5 and 6 November, investors are revising what Anthropic is worth ahead of its listing. According to Bloomberg, potential buyers now discuss 1.2 to 1.3 trillion USD, and some market participants see about 1 trillion USD as a more comfortable level.

This post covers how valuation expectations changed since September, why the pressure grew in November and what a lower price means for the listing. For the full picture of the IPO and its risks, see our Anthropic IPO guide.

How Expectations for the Anthropic Valuation Changed

September: about 2 trillion USD. On 11 September Reuters reported that Anthropic was in talks to bring in Nvidia as an anchor investor. According to two sources, the company aimed to raise up to 100 billion USD at a valuation of about 2 trillion USD. That was the benchmark for the planned listing.

October: about 1.5 trillion USD. On 15 October Reuters reported that after an investor day with Anthropic's management, some current and potential investors discussed a value of about 1.5 trillion USD. The agency cited four people familiar with the matter. The reason was slower quarter-on-quarter revenue growth, even though the business kept expanding fast.

November: 1.2 to 1.3 trillion USD and lower. On 6 November Bloomberg reported that potential buyers discuss a range of 1.2 to 1.3 trillion USD, and some weigh a value as low as 1.1 trillion USD. Talks continue, and no final decision has been made.

According to Bloomberg, these market participants favour a lower Anthropic valuation before the IPO:

• Michael Alfaro, chief investment officer at Gallo Partners, said even before the 5 November sell-off that Anthropic needed to target 1.3 to 1.4 trillion USD to build a quality order book.
• David Rainville, technology portfolio manager at Sycomore Asset Management, said that at 1.2 trillion USD the company should have no problem finding buyers.
• Max Kettner, chief multi-asset strategist at HSBC, named about 1 trillion USD as a more comfortable level that could reduce the risk of sharp swings once trading starts.

Why the Pressure Grew Right Now

The new revision followed a sharp drop in the tech sector: the Nasdaq 100 index fell 6.4% on 5 November. When listed tech companies get cheaper, potential buyers of Anthropic shares ask for a more attractive IPO price.

The US midterm elections added more pressure. As Euronews reports, governor candidates who backed limits on data centre construction won in Texas, Ohio and Georgia. In Ohio, voters in 15 municipalities backed bans or other restrictions. Texas governor-elect Gina Hinojosa promised a moratorium on approvals of new data centres until the state legislature passes laws that protect residents from the strain on power grids, water supplies and the environment.

For Anthropic this creates a risk of delays in getting new computing capacity. Longer approval and construction of sites could slow the training of future Claude models and the expansion of customer service, and stretch out the use of costly temporary capacity. The scale of the impact is still unclear: sites already approved or under construction will mostly keep going, and the main difficulties will hit the next wave of projects.

What This Means for the Anthropic IPO

A move from 2 to 1.2 trillion USD cuts the expected value by 800 billion USD, or 40%. At 1 trillion USD the gap reaches 50%.

For Anthropic a lower price means selling a bigger share of the company to raise the same amount. Raising 100 billion USD would take roughly 5% of the company at a 2 trillion USD valuation and about 8% at 1.2 trillion USD. For buyers a lower price creates a more attractive entry point, though on its own it does not guarantee that the shares will rise.

The roadshow was initially expected to start in the week of 9 November. According to Reuters, potential investors allow for a delay of the listing if pressure on the market persists. As The Telegraph wrote on 6 November, the odds of a November IPO on Polymarket fell sharply, and traders on the platform began to expect the deal in December. Market volatility and concerns over Anthropic's 895.4 billion USD of infrastructure commitments fed the talk of a delay, which would let the company wait for better listing conditions.

Conclusion

Anthropic is going to public investors at a time when they are getting stricter about the value of AI companies. Fast business growth alone no longer holds up the earlier valuation. A cut to 1.2 to 1.3 trillion USD could help the company attract buyers and complete the listing. At 1.1 trillion USD or lower, the IPO price would sit close to the 965 billion USD valuation of the Series H round in May 2026, as covered in our post on Anthropic valuation.

How the shares trade afterwards will depend on Anthropic's ability to turn demand for Claude into steady profit. For investors, the final IPO price and the financial results that have to justify it will matter most.
