Anthropic files for IPO under the ticker “ANT”

Anthropic formally filed for an initial public offering on Monday. After weeks in which leaked drafts of its S-1 circulated in the press, the AI developer is now set for one of the most closely watched market debuts in recent U.S. history. The shares are to trade under the ticker “ANT.”

Revenue climbs, losses linger

According to the SEC filing, Anthropic booked $16.3 billion in the first half of 2026, up from $1.2 billion in the same period a year earlier. Its operating loss came to $693 million — a marked improvement on the $2.1 billion operating loss recorded in the first half of 2025.

The net loss, however, reached $80.7 billion. The company says this was largely the result of noncash accounting adjustments tied to convertible debt. The prospectus states plainly that the firm “may not achieve or sustain profitability in the future.”

The scale of the enterprise business

The document also shed light on Anthropic’s corporate customer base. As of the end of September, it had more than 11,900 customers spending $100,000 or more a year, 1,900 spending $1 million or more, and about 250 spending $10 million or more.

Control stays with the founders

As previously reported, the governance structure will let the seven co-founders retain control of the company even after it goes public. Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah will form a “Founder LLC” holding a combined 50.1% of shareholder voting power. Anthropic describes this as a way to preserve its AI safety mission.

The Long-Term Benefit Trust, set up in 2023, will have the authority to appoint most of the board.

The arrangement is contentious: voting power is not proportional to the founders’ economic stake, meaning public shareholders will have little practical say over a company building technology that, by its own admission, carries “catastrophic or existential risks to humanity.”

Anthropic has not yet disclosed how much it hopes to raise or its proposed share price.
