Anthropic, the artificial intelligence company behind the Claude chatbot, registered a net loss of over $80 billion in the first six months of 2026, according to a report by The Wall Street Journal.

However, the details in the report, based on undisclosed financial documents, could not be independently verified immediately.

Published on Tuesday (October 20), the report indicated that the company's losses widened compared to the same period last year, when Anthropic posted a loss of roughly $13 billion.

According to preliminary disclosure filings, the steep rise in losses this year was primarily driven by accounting expenses.

The report noted that nearly $72 billion of the accounting charges stemmed from fluctuations in the valuation of convertible debt instruments and other financial assets issued by Anthropic to raise capital.

These non-cash charges accounted for the bulk of the total loss.

Meanwhile, the report highlighted that Anthropic is negotiating several potential agreements that could see it spend up to $750 billion over the coming years to expand its computing capacity.

As competition intensifies across the artificial intelligence sector, tech companies face mounting spending pressures.

Investors are increasingly questioning the eventual returns on massive investments poured into advanced microchips and data center infrastructure.

Anthropic is currently preparing to go public through an Initial Public Offering (IPO).

Potential investors are closely examining the firm's financial position as part of this process.

In its filings, the company identified potential operational risks, including harms arising from product misuse, advanced cyberattacks, and the threat of uncontrolled AI systems being leveraged for blackmail.

Anthropic did not immediately respond to requests for comment regarding the matter.

Earlier in September, news agency Reuters reported that Anthropic recorded a net loss of $42 billion in 2025, citing preliminary documentation filed ahead of its planned public listing.

Despite the heavy losses, Anthropic's revenues grew exponentially.

According to The Wall Street Journal, the company generated $16.3 billion in revenue during the six-month period ending June 30, 2026, up sharply from $1.1 billion recorded in the corresponding period of the previous year.

On the other hand, spending on AI infrastructure nearly quadrupled, approaching $9 billion.

The company's coding assistant, Claude Code, has gained significant traction among software developers and application creators.

However, following a recent investor meeting in San Francisco, market observers have begun reassessing Anthropic's projected valuation.

Four sources familiar with the matter told Reuters that several existing and prospective investors attending the meeting were considering a lower valuation following the release of new financial figures.

According to three of those sources, the company's valuation during a planned share sale in November could stand around $1.5 trillion, down from earlier estimates of nearly $2 trillion.

Last week, Anthropic stated that artificial intelligence might soon acquire the capability to self-replicate on standard household devices within months.

The rapid acceleration of the technology continues to raise growing concerns regarding its security risks and economic impacts.
