• Anthropic’s potential IPO valuation has tumbled to $1.2–$1.3 trillion from as high as $2 trillion, a 35–40% cut, amid a historic tech rout.
  • The AI-stock selloff, triggered by midterm elections and data-center opposition, has cast doubt on the November listing timeline.
  • Despite the repricing, prediction markets still imply a 79% chance of an IPO announcement before February 2027, though the figure remains unverified.

Valuation Expectations Collapse

Anthropic’s long-anticipated initial public offering is facing a sharp repricing, but not a cancellation. As of November 6, 2026, prospective investors were discussing a valuation of $1.2 trillion to $1.3 trillion, down from earlier expectations of up to $2 trillion, according to people familiar with the matter. That represents a 35–40% reduction from the most optimistic estimate—a dramatic reset for a company that has come to symbolize the AI investment boom.

The shift follows a brutal selloff in technology stocks. The Nasdaq 100 fell 6.4% on November 5, erasing roughly $2.3 trillion in market value, after U.S. midterm elections strengthened political opposition to data-center expansion. The rout has forced investors to reassess the financing costs and infrastructure obligations facing AI developers.

Reuters (NASDAQ:TRI) reports growing doubts about whether Anthropic can complete a listing this month, while negotiations over an acceptable price continue. The roadshow—formal marketing to prospective investors—was expected to begin the week of November 9, with pricing the following week. But that schedule now looks increasingly fragile. Anthropic declined to comment.

Timetable Under Pressure

The immediate trigger for the valuation cut was the market turmoil, but the underlying issues are more structural. Rising interest rates have heightened concerns about financing costs for data-center developers, while aggressive AI spending is weighing on major technology companies’ cash flows. That raises questions about both the cost and timely availability of Anthropic’s future computing capacity.

Adding to the pressure, Goldman Sachs (NYSE:GS) analysts estimated that temporary project halts could affect roughly 45% of planned U.S. data-center capacity expansion, although they expected the disruption to be short-lived. The estimate underscores how political opposition—centered on electricity demand, water consumption, and local utility bills—could translate into permitting restrictions and delays.

“What institutional investors like us are really focused on is regulatory stability,” said one person involved in the discussions, who requested anonymity to speak candidly. “Italy in this regard has been on a very steady growth trajectory”—a comment that, while referring to a different market, highlights the broader investor appetite for predictable regulatory environments.

Financial Performance and Governance

Anthropic’s financials illustrate the central tension facing the company. Third-quarter revenue reached approximately $17 billion, up about 1,127% year over year, but sequential growth slowed to 47% from 144% in the second quarter and 132% in the first. The company posted a net loss of $23.29 billion for the quarter, and an operating loss of nearly $1.3 billion for the first nine months, according to reporting on the amended prospectus.

Aggregate purchase and lease commitments stand at approximately $895.4 billion, substantially all related to computing and infrastructure. That multiyear commitment underscores the scale of investment required to sustain growth—and the risks if financing conditions tighten.

The IPO’s governance structure also warrants attention. A founder-controlled entity would hold a special share carrying 50.1% of general shareholder voting power, while the Long-Term Benefit Trust would generally elect a majority of directors. Public investors would therefore acquire economic exposure without proportionate control.

Market Implications

The valuation debate extends beyond Anthropic. A delayed offering could further weaken confidence in the AI ecosystem and pressure a stock market heavily weighted toward large technology companies. Conversely, a successful offering at a lower price could demonstrate that investors still support AI expansion—just on less generous terms.

Competition from OpenAI and cheaper models, including Chinese alternatives, is increasing scrutiny of pricing and sustainable margins. OpenAI confidentially filed its prospectus in June, with executives indicating a 2027 debut, and Anthropic’s reception could become a reference point for investor appetite toward other AI-model developers.

Morningstar (NASDAQ:MORN) analysts argue that the selloff need not stop the IPO, while Reuters quotes Cherry Lane Investments’ Rick Meckler as expecting continued investor interest in major AI companies, but some retreat from private-market valuations. Those views support the possibility of an offering without endorsing its former price expectations.

What to Watch

The most useful indicators will be revenue growth, operating margins, computing costs, delivery of contracted capacity, and the actual IPO terms—not prediction-market odds alone. October revenue is a particularly important missing data point: prospective investors want evidence that growth has strengthened after the recent sequential slowdown.

A successful listing at a lower valuation could still be a landmark event for the AI industry, proving that public markets remain open to high-growth, cash-burning companies. But the era of sky-high valuations may be giving way to a more discerning approach.

Correction: An earlier version of this article misstated the percentage decline in Anthropic’s valuation. It is 35–40%, not 40–45%.
