Anthropic Files for ANT IPO: $16.3B Revenue, $80.7B Loss

Anthropic's initial public offering filing, made public on Monday, shows revenue of $16.3 billion for the first six months of 2026, up from $1.2 billion in the same period a year earlier. The Claude developer also disclosed an $80.7 billion net loss for that half-year, a figure dominated by a non-cash accounting charge rather than day-to-day operating losses.

What the S-1 filing says

Anthropic publicly filed its Form S-1 registration statement with the Securities and Exchange Commission on Monday, October 26, 2026, Reuters reported. The company plans to list its Class A common stock on the Nasdaq Global Select Market under the ticker "ANT," according to the filing as reported by Yahoo Finance. Goldman Sachs and Morgan Stanley are leading the offering, Reuters reported. The public filing follows a confidential draft registration statement Anthropic submitted to the SEC in June 2026, according to Capital Brief. The registration statement has not yet become effective, meaning no shares can legally be sold yet, and Anthropic has not disclosed its targeted valuation or the number of shares it plans to sell, according to Reuters.

Revenue jumped twelvefold, but so did the loss

Anthropic reported revenue of $16.3 billion for the six months ended June 30, 2026, up from $1.2 billion a year earlier, according to the filing as reported by Reuters. That clarifies how the "$1.2 billion" figure circulating in early coverage of the filing should be read: it is the company's revenue for the comparable first half of 2025, not its current number. For context, Anthropic's full 2025 fiscal-year revenue was $4.6 billion, with an operating loss that widened to $8.06 billion, according to Reuters reporting carried by Benzinga. Second-quarter 2026 revenue alone came in at $11.56 billion, according to the S-1 as cited by the financial newsletter The VC Corner, indicating growth accelerated within the half.

The loss figure needs similar context. Anthropic's net loss reached $80.7 billion in the first half of 2026, compared with a loss of $13 billion a year earlier, according to the filing. But approximately $72 billion of that loss reflected a non-cash accounting charge tied to changes in the value of convertible notes and other financing instruments, Reuters reported, citing the prospectus. That charge does not represent cash leaving the business; it reflects how accounting rules require a company to revalue convertible debt as its underlying equity value rises. Reuters reporting carried by Benzinga similarly found that Anthropic's roughly $42 billion net loss for full-year 2025 was largely driven by an accounting charge rather than operating costs. The $80.7 billion figure should not be read as a cash operating loss without that distinction.

Who actually controls the stock once it trades

The filing lays out a share structure that keeps control with Anthropic's founders rather than public shareholders. Immediately before the offering, Anthropic will issue a single Class F share to an entity owned by its seven co-founders, carrying 50.1% of the voting power on most shareholder matters, according to the S-1 as reported by Yahoo Finance. The filing says that makes Anthropic a "controlled company" under Nasdaq rules. Public investors buying Class A shares will get one vote per share, but the filing warns the structure "may effectively eliminate the ability of holders of our Class A common stock to influence important decisions, including a change in control."

Separately, the Long-Term Benefit Trust, a body of five financially disinterested trustees, will elect a majority of the board through a special class of stock, per the filing. Anthropic has also set aside roughly 847 million non-voting shares, about 5% of its fully diluted share count as of June 30, in a wholly owned subsidiary dedicated to the company's public-benefit purpose, and its co-founders have each pledged to give 80% of their personal equity to philanthropic causes, according to the filing. For a prospective shareholder, buying Class A stock provides economic exposure to Anthropic's results without a meaningful vote on corporate-control questions.

What's still unknown about price and size

The S-1 leaves the commercial terms blank: no share count, no price range and no stated company valuation, according to Capital Brief and The VC Corner, both of which reviewed the filing. The Wall Street Journal reported Anthropic could raise $100 billion or more and value the company at between $1.5 trillion and $2 trillion, according to Reuters. For comparison, Anthropic's IPO follows that of Elon Musk's SpaceX, which priced a $75 billion offering in June that valued the company at $1.75 trillion, Reuters reported. Bloomberg separately reported, via Capital Brief, that Anthropic was seeking a valuation matching or exceeding SpaceX's $1.8 trillion mark, a figure that does not exactly match Reuters' $1.75 trillion IPO price and may reflect a later secondary-market valuation rather than SpaceX's actual offer price. Anthropic itself was valued at $965 billion in its most recent private funding round in May 2026, according to Capital Brief, meaning the IPO target under discussion would represent roughly 55% to 107% above that private mark, if it holds.

Some market participants are skeptical that current revenue can support that target. Investor Michael Burry highlighted the valuation gap between Anthropic and established S&P 500 companies, noting Anthropic's valuation would equal the combined value of 78 S&P 500 companies, according to Benzinga reporting carried by Yahoo Finance. Chan Ahn, a former Goldman Sachs and JPMorgan executive, told Benzinga that a $2 trillion valuation would require exceptional revenue growth and margin expansion from current levels. Neither comment predicts where shares will trade; both react to the gap between Anthropic's current revenue base and the valuation range under discussion.

Also unresolved is sequencing against a direct competitor. Anthropic remains locked in a race with OpenAI to lead advanced AI development, and OpenAI confidentially filed for an IPO in June and is expected to list by early 2027, Reuters reported. That timeline would make Anthropic the first of the two companies to trade publicly.

Dated catalysts ahead

Bloomberg reported, via Capital Brief, that the roadshow, when bankers market the deal to institutional investors, is set to begin November 9. Reuters, citing the Wall Street Journal, reported that Anthropic is targeting a public listing in the week of November 16, though the timing could change according to people familiar with the matter. Price range and share-count details are expected to emerge before that window, once Anthropic and its underwriters gauge investor demand. Until the SEC declares the registration statement effective and a price is set, there is no tradable Anthropic stock and no confirmed valuation.
