Anthropic lost more than US$80 billion in the first half of 2026, according to reports

Accounting charges behind the loss

72 US$ billion

Most of the loss came from US$72 billion in accounting charges tied to the value of convertible notes and other instruments issued to raise money, according to a draft prospectus for its stock market listing.

Revenue rose to US$16.3 billion in the six months to Jun 30, from US$1.1 billion a year earlier, while spending on AI infrastructure nearly quadrupled to almost US$9 billion.

Some investors are discussing a valuation of around US$1.5 trillion for the share sale expected in November, below the roughly US$2 trillion previously expected, people familiar with the matter said.

Anthropic did not respond to a request for comment, and the figures could not be independently verified.
