Anthropic, the company behind the Claude AI assistant, officially filed paperwork with U.S. regulators on October 26 to go public on the Nasdaq Global Select Market under the ticker symbol "ANT." The reaction came fast, and most of it fixated on the same startling number: an $80.7 billion net loss.
That number is almost entirely misleading, and here is why it matters to understand that before anyone touches this stock.
The company's real operating loss for the first half of 2026 was $693 million — an accrual-accounting figure reflecting costs including staff, computing power, and infrastructure — set against $16.3 billion in revenue over those same six months. That works out to roughly four cents per dollar of operating loss against every dollar Anthropic earned. The $80.7 billion headline figure includes a $72.4 billion non-cash accounting adjustment. Early investors in Anthropic received convertible notes before the company went public. As Anthropic's estimated worth climbed toward $1.5 trillion to $2 trillion, accounting standards required the company to record the rising value of those notes as a loss on its financial statements. No cash went anywhere.
Goldman Sachs and Morgan Stanley are managing the offering. Investors in the United States, United Kingdom, Canada, and Australia are named in the filing as eligible markets. The registration statement is not yet effective; no securities can be sold until the SEC formally declares it so.
The share structure inside the filing is the part most coverage skipped entirely. Anthropic created multiple classes of stock that separate economic ownership from actual control of the company.
Public buyers on the Nasdaq will receive Class A shares, which give economic exposure to the company's performance — your shares may rise or fall in value; revenue is not automatically distributed to shareholders. The filing also creates Class N shares, which certain institutional investors including Amazon Web Services receive through convertible note conversions. A single Class F share, held by a Founder LLC on behalf of the seven co-founders, carries 50.1 percent of total voting power, meaning the founders retain governance control over the company regardless of how many Class A shares are sold to the public. Class T directors sit at the governance level that drives the company's direction. In plain terms, retail investors buying ANT on listing day will own a stake in a fast-growing AI business, but the people running Anthropic and setting its mission are structurally insulated from public shareholder pressure. Multi-class share structures are common in tech IPOs, but Anthropic's version is more layered than most.
Infrastructure spending is another major theme inside the filing. Training frontier AI models at the scale Anthropic operates requires data centers consuming enormous quantities of electricity. The S-1 lists power grid capacity as a direct business risk. Capital expenditure on compute and energy infrastructure is projected to remain heavy for years, which is one reason operating losses are likely to continue even as revenue climbs steeply.
Revenue growth has been extraordinary by any measure. The $16.3 billion for the first half of 2026 came primarily from enterprise API access to Claude and from cloud partnerships with Amazon Web Services and Google Cloud. Businesses are embedding Claude-powered features into their own products at an accelerating pace.
The filing also extends to investors in the European Economic Area, Japan, and Switzerland through separate country-specific provisions, without requiring Anthropic to list on local exchanges in those markets.
The next document to watch is an amended filing called the S-1/A, which will disclose the actual price range per share and the total number of shares being offered. That is expected sometime in November 2026, with a roadshow potentially beginning around the week of November 9, though neither date is confirmed. Trading cannot begin until the registration statement is declared effective and the offering is priced.
For anyone who will never buy a single ANT share, this IPO still matters. The price Anthropic's stock opens at will become the first publicly traded benchmark for the value of a frontier AI lab. Every private AI company — OpenAI, xAI, and others — will be measured against that number for years.
