Anthropic IPO Valuation Slides From $2.5 Trillion Talk to $1 Trillion

One prospective investor now believes Anthropic may be worth $1 trillion — down 50% from the near-$2 trillion valuation investors were discussing in October, and below the roughly $1.5 trillion figure that circulated later. The estimate, first reported in the run-up to Anthropic's planned IPO, is one investor's view of a private company. No reported result or set IPO price confirms it.

The number matters beyond one startup. Anthropic remains private, but the companies that back it, host its models and sell it chips — Amazon (NASDAQ:AMZN), NVIDIA (NASDAQ:NVDA), Alphabet (NASDAQ:GOOGL) and Microsoft (NASDAQ:MSFT) — are public, and their reported results already carry Anthropic's swings. The price Anthropic sets at its IPO will give every one of those holdings a public reference point.

What does the lower valuation mean for Anthropic's finances?

The reduced estimate lands on a business that is still growing fast and spending even faster. Anthropic's third-quarter revenue reached $16.96 billion, up 47% from the prior quarter. Growth slowed from 144% in the quarter before. The company also reported a $23.29 billion quarterly net loss, a figure that includes nonoperating accounting effects.

Future spending is the larger issue. Anthropic has reported about $895.4 billion in future computing and infrastructure commitments. About $69.8 billion of that falls due over the following 12 months. Meeting those commitments depends partly on whether Anthropic's partners can finance and deliver the capacity.

NVIDIA's CFO, Colette Kress, described the structural problem on the company's August 26, 2026 earnings call: "The Frontier AI labs have extraordinary demand for training and inference compute, but they are growing faster than what their balance sheets and credit profiles can support." NVIDIA said it has committed nearly $50 billion to frontier AI labs and expects demand from labs it supports with its own balance sheet to make up roughly a quarter of its business next year.

What do investors want?

Big investors want a lower entry price. Three prospective institutional investors told the Wall Street Journal that the expected $1.5 trillion valuation probably needs to fall. Anthropic had reportedly desired to raise as much as $100 billion. Investors are now discussing a smaller offering of around $80 billion.

The pressure follows a broad technology selloff. NASDAQ companies lost about $2.5 trillion in market value during Thursday's rout. NVIDIA fell 8.8% in the week ended November 6, from $204.64 to $186.64, and is down 21.4% over the past month. Amazon held up better, rising 7.88% over the same week. Microsoft gained 1.67%.

How have Anthropic's swings already moved partners' profits?

Changes in Anthropic's value have already flowed through its partners' reported earnings. Amazon's net income for the quarter ended June 30, 2026 included $53.4 billion in pre-tax gains, mostly from its Anthropic stake. Those gains lifted GAAP earnings per share to $5.75, well ahead of the $1.82 consensus. The next quarter reversed the effect: Amazon recorded $1.21 billion in net non-operating expense, and GAAP EPS of $1.89 missed expectations of $1.96.

Microsoft's quarter ended June 30, 2026 included a $3.2 billion gain from its Anthropic stake. A lower IPO price would give these holdings a lower public reference point, and would mark down a benchmark that Wall Street currently values on private marks.

Spending plans add to the pressure on partners. Amazon guides to about $220 billion in 2026 capital spending, and CEO Andy Jassy said the company expects to "spend meaningfully more in 2027." CFO Brian Olsavsky warned that "the outsized growth of AI puts margin pressure on the business as a whole because the margins are lower there."

NVIDIA addressed the criticism of its lab investments directly, saying: "We know some will call this circular financing." The company has faced exactly that argument — that its equity and credit support for AI customers recycles into its own chip sales.

Why does one company's valuation matter for the AI sector?

The effects reach well beyond Anthropic. A lower valuation could pull down expectations for other AI companies. It could also make investors more doubtful about the huge infrastructure spending that supports the industry — the power, cooling and networking suppliers riding the expansion.

Anthropic is a test of whether Wall Street's demand for AI investments is weakening. Right now, buyers are asking for a lower price.

What happens next?

The next milestone is the IPO itself, planned for before Thanksgiving. Some prospective investors are questioning whether Anthropic should keep that schedule; delaying the listing until markets improve remains possible.

In August, NVIDIA CEO Jensen Huang said of the AI labs: "Two of the companies will likely go public soon, and others will follow."

For long-term holders of Amazon, NVIDIA and Microsoft, the price Anthropic sets will reveal what the market will pay for AI growth. If the most closely watched AI lab can command only $1 trillion, investors will look harder at every dollar being spent on AI infrastructure.
