The Claude maker filed to list on Nasdaq under the ticker ANT with $16.3 billion in first-half revenue and an $80.7 billion loss, as Reuters reports Nvidia is in talks to invest
Anthropic filed its S-1 with the Securities and Exchange Commission on October 26, naming Nasdaq and the ticker ANT for a listing expected as soon as November. The filing reported $16.3 billion in first-half revenue and an $80.7 billion net loss, most of it an accounting charge on convertible notes.
Revenue is climbing fast. Anthropic told investors in mid-October that third-quarter sales reached $16.8 billion, up 45% from the second quarter, and that it was profitable on an adjusted basis. Reuters reported that prospective investors have discussed valuing the company at about $1.5 trillion, below the $2 trillion floated earlier, and that Nvidia is in talks to invest in the offering.
Why it matters
Anthropic's listing will test whether public investors pay trillion-dollar prices for AI companies losing billions a year.

Legal
The U.S. government filed a notice of appeal seeking to invalidate the Northern District of California decision, according to the S-1.

Scenarios
1
Anthropic IPO prices above $500 billion, validating employee bet
Likely
Discussed by: Goldman Sachs and JPMorgan banking analysts (per The Information and Bloomberg reporting on IPO preparation); Tom Tunguz at venture firm Theory
If Anthropic's revenue continues its trajectory and the IPO prices at a premium to the $350 billion tender offer valuation, employees who held their shares will have been vindicated. Bankers advising on the listing reportedly expect the raise to exceed $60 billion, which would make it the second-largest tech IPO in history. This scenario depends on sustained enterprise demand for Claude, a receptive public market window, and the company's novel governance structure surviving Securities and Exchange Commission (SEC) scrutiny without material changes.
2
AI IPO traffic jam forces Anthropic to delay or discount
Possible
Discussed by: Fortune and Crunchbase analysts who describe SpaceX, OpenAI, and Anthropic's combined listings as a '$3 trillion stress test' for public markets
SpaceX, OpenAI, and Anthropic are all targeting IPOs in the second half of 2026. If SpaceX goes first and absorbs a large share of available institutional capital, Anthropic may face a thinner investor pool. A delay into early 2027 or a reduced valuation at listing would mean employees who held through the tender offer missed their best exit window. The risk is amplified if the broader stock market weakens or if AI revenue growth decelerates across the sector.
Discussed by: Harvard Law School's corporate governance blog; legal analysts covering Anthropic's Public Benefit Corporation structure
Anthropic's governance structure — a Public Benefit Corporation with an independent trust that gradually gains majority board control — has no precedent in a major tech IPO. If the SEC requires material changes to the Long-Term Benefit Trust's powers as a condition of listing, it could delay the offering or force Anthropic to dilute its safety-mission commitments. This would test whether Anthropic's founding premise — that safety and scale are complementary — can survive the transition to public ownership.
4
Revenue growth stalls, valuation compresses before listing
Unlikely
Discussed by: Skeptical analysts who note that Anthropic's implied revenue multiple remains extremely high even at $350 billion
Anthropic's valuation of $350 billion against $30 billion in annualized revenue implies investors are pricing in continued hypergrowth. If enterprise AI spending slows — due to budget tightening, regulatory friction, or customers consolidating around fewer vendors — Anthropic could approach its IPO with decelerating growth and face a valuation markdown. Employees who held through the tender offer would find themselves holding shares worth less than the $350 billion they could have sold at.
5
Anthropic prices at or above its $965 billion private valuation
Uncertain
Resolves by End of 2026
Discussed by: Bankers on the listing and IPO analysts quoted by CNBC and the Associated Press
A listing near the June round's $965 billion post-money valuation would keep the company ahead of OpenAI, which has not yet listed, and reward employees who refused to sell at $350 billion. It would also require public investors to look past an $80.7 billion first-half loss and underwrite continued revenue growth from a $47 billion annual run rate.
6
Staggered lock-up releases push the stock down after the debut
Possible
Resolves by Feb 28, 2027
Discussed by: Analysts covering the IPO, including commentary published by AInvest on the tender offer shortfall
Insiders can sell shares in four waves beginning 27 days after the first day of trading, far sooner than the standard 180-day lock-up. Employees who declined to sell in the April tender offer at $350 billion hold large paper gains, and a wave of sales could weigh on the share price within the first three months of trading.
7
FTC testimony fight pushes the listing past January
Possible
Resolves by Jan 31, 2027
Discussed by: CNBC, which confirmed the FTC testimony demands, and Axios, which first reported them
The FTC is investigating whether AI products from Anthropic, OpenAI and other companies harm consumers, and has demanded that Anthropic executives testify. If the agency turns that inquiry into a lawsuit or a consent order before pricing, Anthropic could delay the offering into 2027 or accept a lower price to get out.
8
Anthropic prices between $1.4 trillion and $1.6 trillion
Possible
Resolves by End of 2026
Discussed by: Reuters, citing sources familiar with the discussions; TheStreet, citing Reuters
Prospective investors have discussed valuing Anthropic at roughly $1.5 trillion, below the $2 trillion figure floated when Reuters reported the offering could raise up to $100 billion. Pricing in that band would still be more than 50% above the $965 billion post-money valuation set in May, and would leave the company well ahead of OpenAI, which has not listed. Getting there requires public investors to look past an $80.7 billion first-half loss and underwrite the $16.8 billion third-quarter revenue figure.
Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
2010–May 2012
Facebook pre-IPO secondary market and employee lockup (2010–2012)
In the years before Facebook's May 2012 initial public offering, a thriving secondary market emerged on platforms like SecondMarket and SharesPost. Facebook employees began selling shares as early as 2007, and by 2011, average share prices on secondary markets had tripled in a single year. Facebook eventually banned employee share sales in 2010, then ran a company-sponsored tender offer before listing at $38 per share and a $104 billion valuation.
Then
Facebook's stock dropped below its IPO price on the first trading day and continued falling for months. Employees who sold pre-IPO at secondary prices actually fared better in the near term.
Now
The stock recovered and ultimately surged, rewarding those who held through the IPO dip. Facebook's experience became the canonical cautionary tale about pre-IPO pricing, showing that tender offer participants and holders can both be right depending on time horizon.
Why this matters now
Anthropic employees face a structurally similar choice: sell at $350 billion now or hold for a potentially higher IPO price. Facebook's history shows this bet can go either way — the IPO price is not guaranteed to exceed the pre-IPO valuation, especially in the short term.
2 of 3
2003–September 2020
Palantir's 17-year private period and direct listing (2003–2020)
Palantir Technologies stayed private for 17 years, creating severe liquidity problems for employees with expiring stock options. From 2016 onward, the company facilitated secondary sales to hundreds of investors at prices between $4.65 and $9.75 per share, while simultaneously blocking some former employees from selling. Palantir eventually went public via a direct listing on the New York Stock Exchange in September 2020.
Then
The direct listing opened at $10 per share, within the range of late-stage secondary prices, meaning employees who sold in the final years before listing received roughly fair value.
Now
Palantir's stock surged in subsequent years, eventually exceeding $50 per share. The company's experience reinforced that long private periods create both retention challenges and, for employees who hold, potentially outsized returns.
Why this matters now
Anthropic's tender offer is the modern, scaled-up version of the secondary liquidity that Palantir had to improvise over years. The key difference: Anthropic is offering liquidity proactively and at high valuations, giving employees a genuine choice rather than forcing them into illiquidity.

August 2004
Google IPO employee windfall (2004)
Google went public on August 19, 2004, at $85 per share — cut from an original range of $108 to $135 after lukewarm investor reception. Roughly 900 of Google's 2,292 employees became millionaires on listing day. Unlike today's tech employees, Google staff had essentially no secondary market to sell into beforehand; their only option was to hold.
Then
The stock closed at $100.34 on its first day, an 18 percent gain, and continued climbing.
Now
Google shares rose from $85 to over $700 within three years. Employees who held through early volatility captured one of the largest wealth-creation events in tech history, establishing the template for why startup employees believe in holding through IPO.
Why this matters now
Google is the story Anthropic employees are telling themselves — that holding through the IPO will deliver returns far beyond what any pre-IPO liquidity event offers. The difference is that Google employees had no alternative; Anthropic employees are actively choosing to forgo $350-billion-valuation liquidity.
