Anthropic IPO: S-1 Filing Shows $16.3B in Revenue and an $80.7B Net Loss
Anthropic has filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission for an initial public offering. It plans to list its Class A common stock on the Nasdaq Global Select Market under the ticker “ANT.” The company announced the filing on October 26, 2026. It has not yet set the number of shares or the price range.
The filing gives the first official look at the finances and governance of the maker of Claude, and the picture is mixed: very fast revenue growth, a large net loss, and a structure that keeps control with its founders.
What did Anthropic confirm?
According to Anthropic’s announcement:
- It filed the S-1 for the proposed offering of Class A common stock.
- It intends to list on the Nasdaq Global Select Market as “ANT.”
- The number of shares and the price range are still to be determined.
- Goldman Sachs and Morgan Stanley are named as the contacts for the preliminary prospectus. Forbes reports, citing the filing, that the two banks are leading the offering.
- The registration statement has not yet become effective, so no securities can be sold or offers accepted yet. The announcement is not an offer to sell shares.
Forbes also reports that Anthropic confidentially filed with the SEC in June and could go public as soon as mid-November. That timing comes from Forbes, not from Anthropic.
How much revenue and loss did Anthropic report?
Per TechCrunch’s reading of the filing, Anthropic’s first-half 2026 results were:
| Metric | H1 2026 | H1 2025 |
|---|---|---|
| Revenue | $16.3 billion | $1.2 billion |
| Operating loss | $693 million | $2.1 billion |
| Net loss | $80.7 billion | Not reported in sources |
The net loss is far larger than the operating loss. TechCrunch reports it was largely driven by noncash accounting adjustments tied to convertible debt, not by day-to-day operations. The company also warns that it may not achieve or sustain profitability.
Forbes adds that Anthropic reported third-quarter revenue of $16.8 billion, up 45%, when it released results in October. The sources do not say what period that growth is measured against.
How big is Anthropic’s enterprise business?
As of the end of September, the filing shows:
- More than 11,900 customers spending at least $100,000 a year
- 1,900 customers spending at least $1 million a year
- About 250 customers spending at least $10 million a year
Who will control Anthropic after the IPO?
Anthropic’s seven co-founders will form a “Founder LLC” holding 50.1% of shareholder voting power. The seven are Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah. Anthropic says the arrangement is meant to protect its AI safety mission, according to the filing.
Separately, the Long-Term Benefit Trust, set up in 2023, will have authority to appoint most of the board.
Critics point out that this gives founders voting power out of proportion to their economic ownership, leaving public shareholders with limited practical influence. Anthropic’s position is that the structure protects its public benefit mission. Both views are reflected in the filing and in TechCrunch’s coverage.
How much has Anthropic committed to spend on computing?
Forbes, drawing on the filing, reports $117 billion in total liabilities as of June 30, 2026. It also reports an estimated $321 billion in future lease obligations that are not yet on the balance sheet because the leases have not started. The filing lists these commitments:
| Provider | Reported commitment | Term |
|---|---|---|
| Microsoft | At least $45 billion | Nov 2026 – May 2033 |
| $114.5 billion | Apr 2026 – Jul 2033 | |
| Amazon | $110 billion | May 2026 – Apr 2036 |
| SpaceX | Up to $120.5 billion | Into 2029 |
| Nscale subsidiaries | Up to $44.6 billion | Into 2033 |
| Lambda | About $41 billion | Into 2034 |
Forbes also reports that total obligations could reach roughly $1 trillion through 2045, and that Anthropic has spent more than $19 billion on AI infrastructure since its founding. Whether revenue can keep pace with these commitments is the central financial question for investors.
What risks does the filing describe?
Forbes reports that the filing lists four broad risk categories: misuse by bad actors, AI acting independently, use by authoritarian governments, and major economic disruption. The filing says AI acting on its own could become “a global security threat of the first order.” TechCrunch notes the company says its technology poses “catastrophic or existential risks to humanity.”
The filing also describes a plan to commit at least 5% of shares to an Anthropic Public Benefit Fund after the listing, subject to stockholder approval.
What is still unknown?
- The offering size, share count and price range
- The target valuation. Forbes cites an outside estimate of $1.5 trillion to $2 trillion, but this is not from Anthropic and is unconfirmed.
- The exact listing date, since the registration statement is not yet effective
Why it matters
Anthropic is one of the most closely watched IPO candidates in the AI sector. Forbes notes the filing arrives as investors are increasingly cautious about returns on AI spending, and that other AI firms, including Switch and Nscale, have delayed their listings, per Reuters. How the market receives “ANT” will likely say a lot about appetite for AI infrastructure-heavy businesses.
