Anthropic reported $16.3 billion in revenue for the first half of 2026 and a net loss of $80.7 billion in its newly public IPO filing Monday, but the enormous bottom-line loss is not the same as its operating loss.
The company’s Form S-1 shows an operating loss of $693 million for the six months ended June 30, down from $2.14 billion a year earlier. Its much larger net loss includes a $72.4 billion fair-value charge on convertible notes, derivative liabilities and simple agreements for future equity, known as SAFEs.
Anthropic said those fair-value changes were primarily driven by an increase in the value of its outstanding convertible promissory notes as its enterprise valuation rose. That accounting adjustment accounts for most of the reported net loss; it should not be read as an $80.7 billion operating shortfall.
The filing provides a detailed view of the business behind Claude as Anthropic seeks to sell shares to the public. The company intends to list its Class A common stock on the Nasdaq Global Select Market under the symbol ANT. It has not determined the number of shares or the proposed price range, and the registration statement is not yet effective.
First-half revenue was $16.286 billion, compared with $1.163 billion in the same period of 2025. Total operating expenses rose to $16.979 billion from $3.298 billion. Revenue therefore grew faster than operating expenses over that period, narrowing the operating loss even as the net loss expanded.
Compute and infrastructure expenses reached $8.945 billion, up from $2.334 billion a year earlier. Personnel expenses rose to $3.152 billion from $538 million, while sales, marketing and partnership expenses climbed to $3.168 billion from $120 million.
Outside operating expenses, Anthropic recorded $8.757 billion in other net expense. It said that change was primarily driven by the initial recognition and subsequent changes in the fair value of assets and liabilities under note purchase agreements. Interest income was $1.111 billion.
The resulting net loss was $80.748 billion, compared with $12.969 billion in the first half of 2025. The filing separates those financing-related valuation effects from the cost of running and expanding the business.
Anthropic also cautioned investors against assuming its recent revenue growth will continue at the same pace. It said the business remains highly capital intensive, expects costs to increase and expects losses to continue as it invests in growth and operating as a public company.
The proposed share sale remains subject to an effective registration statement. Anthropic said securities cannot be sold, and offers to buy cannot be accepted, before that step is complete.
