Anthropic files to go public with $16.3 billion in half-year revenue — and an $80.7-billion loss

Artificial intelligence firm Anthropic filed its prospectus with the U.S. Securities and Exchange Commission on Monday morning, Reuters reported, opening the books of one of the world's most important AI companies for the first time ahead of a closely watched public listing.

The company plans to list on the Nasdaq under the ticker symbol "ANT," according to its filing as reported by JBizNews, which would make it the first of the major AI model makers to test the public market. Chip stocks rose in early trading on the news, with Nvidia gaining 1.4%, Micron jumping 2.3% and Broadcom adding 1.5%, JBizNews reported.

The filing showed revenue of $16.3 billion in the first six months of 2026, compared with $4.6 billion for all of 2025, according to reports on the document — growth that reflects how fast businesses have adopted Anthropic's Claude models. Infrastructure spending reached $9 billion in the same period, underscoring the cost of building the computing capacity behind the models.

The filing also reported a net loss of $80.7 billion through June, a figure reports on the filing said was driven largely by accounting charges rather than operational shortfalls — a distinction investors will test as they weigh whether the company's growth justifies its infrastructure bill.

The filing landed in a jittery week for AI stocks. Meta shares fell in early trading after the company launched offerings of about $35 billion in common stock and convertible preferred shares to fund its AI expansion, JBizNews reported, while neocloud firms CoreWeave and Nebius slipped 5.4% and 3.9% respectively on Monday after Elon Musk said in an X post that markets had "almost entirely shut off access to money" for companies without substantial revenue independent of AI data centres.

For Canada, the filing is a stress test for the whole AI bet. Canadian pension funds and investors hold exposure to the AI buildout through global equities, and Canadian AI firms and data-centre projects face the same question Anthropic's numbers pose: whether revenue growth can keep pace with infrastructure spending once markets stop paying for promises alone. The filing's answer — revenue up sharply, costs up faster — will frame that debate through earnings season, with Alphabet, Microsoft and Amazon all reporting this week.

What happens next is the roadshow: the filing's reception will set the terms for the year's biggest AI listing, and whether early strength in tech shares holds through an afternoon that also brings the Federal Reserve's Wednesday decision into view.
