Anthropic files for IPO as $80 billion loss raises questions over AI valuations

Anthropic, the artificial intelligence company behind the Claude chatbot, publicly filed for a US initial public offering on Monday, October 26, revealing explosive revenue growth alongside enormous losses and spending commitments that could test investor confidence in the AI industry.

The company plans to list on the Nasdaq under the ticker ANT, potentially becoming the first major developer of frontier AI models to enter public markets.

The offering comes at a difficult time for technology stocks, with rising borrowing costs and concerns about AI infrastructure spending putting pressure on valuations.

Revenue surges as losses reach $80.7 billion

Anthropic reported revenue of $16.29 billion for the first six months of 2026, compared with $1.16 billion during the same period last year.

The figure also exceeded its entire 2025 revenue of $4.59 billion, reflecting rapid adoption of Claude and the company's AI coding and enterprise services.

However, Anthropic recorded a net loss of $80.7 billion during the first half of the year, largely reflecting accounting adjustments linked to the rising valuation of convertible financial instruments.

Its operating loss was considerably smaller at $693 million, compared with an operating loss of $8.06 billion throughout 2025.

The distinction is important for investors assessing whether Anthropic's underlying business is approaching profitability despite its substantial infrastructure requirements.

Valuation expectations fall from $2 trillion

Anthropic's IPO could value the company at approximately $1.5 trillion, below earlier expectations of around $2 trillion.

The company raised $65 billion in May at a valuation of $965 billion, making it one of the world's most valuable privately held technology companies.

Investors have recently become more cautious about paying extraordinary valuations for AI businesses, particularly as financing costs increase and concerns grow about the returns generated by expensive data centers.

Anthropic has committed more than $500 billion to cloud computing and infrastructure arrangements over the coming years, including agreements involving major investors and technology partners.

A major test for the AI industry

The offering could become an important indicator of whether investors remain willing to finance the industry's aggressive expansion.

Several AI infrastructure companies have postponed their own stock market debuts amid market volatility, leaving Anthropic facing considerable scrutiny.

Its financial disclosures also highlight reliance on a relatively concentrated customer base and major computing partners, including Amazon and Google.

The company has not disclosed the number of shares it intends to sell or the proposed offering price.

Anthropic is targeting a possible November listing, although the timetable remains subject to market conditions.

A successful debut could strengthen confidence across the AI sector and establish a valuation benchmark for competitors, including OpenAI.

A disappointing reception, however, could intensify concerns that the enormous capital flowing into artificial intelligence has moved ahead of the industry's ability to generate sustainable profits.
