Anthropic Investors Weigh $1.5T IPO Value, Down From $2T

Some current Anthropic investors and prospective investors in its upcoming IPO are weighing a lower valuation after the company’s latest financial disclosures, Reuters reported on 15 October 2026, citing four people familiar with the matter. Some investors who attended Anthropic’s investor day on Wednesday discussed a valuation of around $1.5 trillion, three of the people said, which Reuters called “a significant step down from the roughly $2 trillion valuation that investors had previously expected for the November share sale.”

The reason, in Reuters’ account, is growth. At Wednesday’s meeting, Anthropic told prospective IPO investors that its third-quarter revenue jumped 45% to $16.8 billion from the previous quarter, and that it was profitable on an adjusted basis during the quarter. Anthropic did not immediately respond to requests for comment, Reuters said.

A one-minute explainer of run-rate revenue: what an AI company’s annualised number does and does not tell you. It teaches the general idea only and says nothing about any organisation in this story.

The key insight: As we read it, the IPO is now being priced on the growth rate rather than the revenue level: Reuters says some investors discussed around $1.5 trillion, down from the roughly $2 trillion previously expected, after quarter-on-quarter growth slowed to 45% from a quarter in which revenue more than doubled.

Update, 19 Oct 2026: CNBC Casts Anthropic as the AI Trade’s Last Big IPO Hope This Year

CNBC reported on 19 October that on prediction market Kalshi, of the 23 companies still open to trade on its market for an official IPO announcement in 2026, only Anthropic offers greater than 50% odds: 75% as of Monday morning, up from the 70% Kalshi posted on 17 October (embedded below). CNBC says Anthropic confidentially filed a prospectus with the Securities and Exchange Commission in early June. Kalshi resolves an “official announcement” as the SEC declaring a company’s S-1 effective, an IPO pricing or an exchange assigning a ticker. CNBC discloses that it and Kalshi have a commercial relationship that includes customer acquisition and a minority investment.

The same market has cooled on others, per CNBC: Plaid fell from 50% odds in January to 10%, Deel to 3% and Databricks to 1%, and OpenAI has a 3% chance of going public this year after CEO Sam Altman said last month it didn’t make sense to go public amid concerns over AI safety. CNBC cites Renaissance Capital that the number of US IPOs priced this year is down 33% compared with 2025, even as proceeds are up sharply on megacap debuts, notably SpaceX in June.

22V Research analyst Dauvin Peterson wrote on Sunday, as quoted by CNBC: “At the end of the day, the revised IPO valuation range starting at $1.5T vs the prior expectation of at least $2T was viewed as disappointing and added fuel to the fire for the AI-related equities that were already under pressure.” CNBC’s article carries no comment from Anthropic.

As we read it, traders still expect the listing this year while the price expectation has come down, the same price-not-demand pushback our piece on two $30B AI infrastructure IPOs tracks.

Update, 19 Oct 2026: Luria on CNBC: Anthropic “will end up being a very speculative investment”

D.A. Davidson head of technology research Gil Luria joined CNBC’s Squawk Box on 19 October, and CNBC titled the segment “Anthropic will end up being a very speculative investment, says D.A. Davidson’s Gil Luria”. CNBC says he discussed “Anthropic’s revenue growth, state of the AI trade, and more.” Only the segment’s title and description were readable to us, not a transcript, so we do not quote his reasoning beyond CNBC’s headline.

Four days earlier, a D.A. Davidson note by Luria and Turner Dischinger, as relayed by Walter Bloomberg on X, said Anthropic’s slowing revenue growth should not be interpreted as a broader AI demand slowdown, and pointed to growing competition from OpenAI and open-weight AI models.

As we read it, calling the shares speculative and calling AI demand intact are not in conflict: the open question in this piece is the price, with Reuters’ sources putting discussions near $1.5 trillion, down from roughly $2 trillion.

Update, 17 Oct 2026: Gerstner expects the IPO in “weeks, not months”

Altimeter Capital chief executive Brad Gerstner, an early Anthropic investor, told Scott Wapner on CNBC’s Halftime Report on 15 October that he expects Anthropic to go public in “weeks, not months,” Benzinga reported. “I suspect here you would have over $500 billion demand for this offering,” he said, and he compared it with SpaceX, where a $100 billion offering generated “about $350 billion of demand,” according to Benzinga.

Gerstner argued that “retail investors are going to be excited about this and long only and mutual funds and sovereigns… and they should get the chance to invest in this business.” Sharing data from Anthropic’s investor day, reporter Kate Rooney said the company told investors its revenue was “just shy of 17 billion for the third quarter,” up 45% sequentially, and quoted DA Davidson as saying “the market does appear to be reading the Anthropic update as a negative,” Benzinga reported.

The timing and the demand figure are Gerstner’s expectations, not a company timetable. As we read it, a holder talking up the order book is one signal; the valuation the book actually clears at is the one this piece is about.

Update, 16 Oct 2026: Anthropic’s KBRA credit rating

The Financial Times reported on 16 October, citing documents it reviewed, that Kroll Bond Rating Agency (KBRA) assigned Anthropic a BB+ issuer rating with a stable outlook in June, one notch below investment grade (FT). We could not open the FT article; the details below come from two accounts of it, by TradingKey and The Deep Dive, and we kept only the points both state.

According to those accounts of the FT report, the rating came before the $35 billion chip financing led by Apollo Global Management to support Broadcom’s AI computing platform. About $4.4 billion of that package was junior debt that depends on Anthropic’s own credit, while the rest was backed by Broadcom. The junior debt yielded around 8.5%, against 5.75% on the senior debt.

Anthropic gave KBRA its revenue, adjusted operating income, annualised first-quarter revenue and internal second-quarter projections, but not free cash flow or EBITDA, so KBRA’s analysts estimated the missing measures and used a risk-scoring approach rather than a full financial model, the FT reported. It also reported that Anthropic had no debt on its own balance sheet at the end of June.

A post by @choblin29 summarising the FT report adds that Kroll was not given detailed terms of up to $42 billion in potential convertible notes from Broadcom to finance Anthropic’s chip leases. That point comes from the post’s account of the FT; neither of the two accounts we read states it.

The rating gap already shows up in loan pricing. Semafor reported on 13 October that Volta Infrastructure’s $5 billion debt deal, which funds a Norway data centre where Anthropic is a major compute buyer, includes a provision under which the interest rate charged to Volta will decrease if Anthropic can get an investment-grade credit rating, citing some of the people familiar (Semafor). Bloomberg reported on 15 October that JPMorgan and Goldman Sachs sold the loan at 6.5 percentage points above the benchmark rate and 95 cents on the dollar, pushing yields past the 11% the banks had earlier floated, and that the debt splits into a $1.3 billion term loan and a $3.7 billion chip loan for about 36,000 Nvidia GPUs (Bloomberg). Bloomberg described the rating trigger as a rate change if Volta gets certain ratings; the Anthropic link is Semafor’s reporting.

As we read it, the rating puts a credit number on the same company investors are now pricing for an IPO: one notch from investment grade, rated on the figures Anthropic chose to share.

Update, 17 Oct 2026: a double-digit yield for Blackstone

The Financial Times reported on 16 October, citing people familiar with the matter, that Anthropic is offering Blackstone a yield of more than 10% to finance its latest chip deal. Blackstone funds would invest $9 billion in the debt, which would be backed by Anthropic’s five-year lease payments on the chips, according to Reuters’ summary of the FT report; Reuters said it could not immediately verify it.

Techmeme’s summary of the FT story describes the debt as part of Anthropic’s $60 billion package to buy Google TPUs, and the FT’s subheading says high borrowing costs complicate the lab’s goal of reaching investment-grade status. We have not read the FT article in full. Sources: Reuters (via syndication), Techmeme.

Later on 17 October we read a full account of the FT report and covered the terms in detail, including the $18 billion junior tranche, the 10% coupon and the 8.5% Anthropic paid four months earlier: Anthropic Offers Blackstone 10% on $9B of $60B TPU Debt.

Update, 16 Oct 2026 (markets): pre-IPO perps split OpenAI and Anthropic

CNBC reported on 16 October that, as CoreWeave sold off, OpenAI’s implied valuation on decentralised exchange Hyperliquid fell more than 4% in 24 hours after briefly slipping under $1.5 trillion, while Anthropic perps rose 2.4% to just over $2 trillion. These are thin pre-IPO perpetual-futures markets priced off an oracle that uses private rounds and secondary trades, not share prices: open interest was more than $41 million in Anthropic against less than $7 million in OpenAI, according to CNBC. CNBC tied the bigger OpenAI drop to its closer ties to CoreWeave (a relationship worth at least $22 billion as of September 2025), and said both contracts are about 15% below last month’s highs (CNBC).

What Some Investors Discussed

According to the people Reuters spoke to, “some investors were disappointed by the slowing sequential growth rate in the latest quarter, as Anthropic’s revenue more than doubled from the first quarter to $11.6 billion in the second quarter.”

Reuters says the Q3 numbers “assuaged some concerns about the massive costs of developing AI systems.” The meeting took place at Anthropic’s headquarters in San Francisco, where attendees, mostly the company’s most prominent investors, met with CEO Dario Amodei and finance chief Krishna Rao, according to Reuters.

The people spoke on condition of anonymity because they are not authorized to speak publicly on the matter, Reuters said. The $1.5 trillion figure is a valuation some investors discussed, according to three of the four people; Reuters does not describe it as a price Anthropic has set.

Some Anthropic investors discussed a valuation of around $1.5 trillion for the IPO, against the roughly $2 trillion previously expected for the November share sale, according to people familiar with the matter cited by Reuters on 15 October 2026.

What Was Posted on X

Walter Bloomberg’s 15 October 2026 headline relay of the report this piece is built on: some investors weighing a $1.5 trillion IPO valuation, down from about $2 trillion, alongside the $16.8 billion Q3 revenue figure. The relay adds nothing beyond the Reuters account.

A clip, posted on 16 October 2026, of Altimeter’s Brad Gerstner on CNBC saying the ‘vibe check’ among Anthropic’s largest investors coming out of the meeting was ‘a nine or a 10 out of 10, very bullish’, on a one- to three-year horizon, and that the market’s reaction to what was reported was more negative than the mood in the room. It is an investor’s read, not a statement from Anthropic.

Investor Chamath Palihapitiya wrote on 15 October 2026 that he suspects 70-80% of revenues at AI companies come from other AI companies funded by venture capital, calling it ‘a revenue quality problem’, quoting Social Capital’s post that AI companies captured about 83% of US venture funding through September. Both figures are his and Social Capital’s estimates; neither refers to Anthropic’s disclosed customer mix.

A post on 16 October 2026 summarising the FT’s report: Anthropic secured a previously undisclosed BB+ rating from Kroll Bond Rating Agency in June without providing free cash flow or EBITDA figures, and KBRA rated $4.4 billion of junior debt in the $35 billion Apollo-led chip financing BB+, at 8.5% against 5.75% for the Broadcom-backed senior debt. The post also says Kroll was not given detailed terms of up to $42 billion in potential Broadcom convertible notes; that point is the post’s account of the FT, which we could not open.

The Bg2 podcast account posted “Anthropic IPO.” on 16 October, quoting Fireside Alpha’s relay of Altimeter’s Brad Gerstner: he predicts an Anthropic IPO could draw more than $500 billion in demand, compares it with what he recalls as about $350 billion of demand for a roughly $100 billion SpaceX offering, and says he does not care whether it prices at $1.5 trillion or $2 trillion. These are Gerstner’s predictions as relayed, not offering terms.

Milk Road AI, on 16 October, summarised the Financial Times report that Kroll Bond Rating Agency gave Anthropic a BB+ issuer rating with a stable outlook in June, ahead of the $35 billion Apollo-led chip financing, and that about $4.4 billion of junior debt rides on Anthropic’s own credit at roughly 8.5% against 5.75% on the senior debt. The figures are the poster’s relay of the FT.

Techmeme relayed the Financial Times report on 17 October that Anthropic is offering Blackstone a yield above 10% to help finance a $60 billion debt package to buy Google TPUs, with Blackstone investing $9 billion of the debt, according to people familiar.

The Information posted on 17 October 2026, linking its 16 October Briefing newsletter ‘Did Anthropic Miss Its Peak IPO Moment?’, that Anthropic’s slowing revenue growth is raising questions about whether it missed its best window to go public, and that investors now see its IPO valuation closer to $1.5 trillion than the $2 trillion bankers had floated. That is The Information’s account; the newsletter is paywalled and we could not read it in full.

The Information re-promoted its 11 Oct report on 17 Oct: investor and analyst estimates say a single Louisiana data center could bring Anthropic $1.3 billion a month in revenue, which it links to Anthropic’s rush to bring about $530 billion of leased computing online. The $1.3 billion is an estimate, not a revenue figure Anthropic has reported.

The Information posted on 17 October that Anthropic’s slowing revenue growth is raising questions about its potential $2 trillion IPO valuation, while private investors remain eager to back AI startups such as Fireworks AI, Baseten and Fal AI. The contrast between public and private appetite is The Information’s.

Prediction market Kalshi posted on 17 October Anthropic’s line that AI could push US GDP to $44 trillion by 2030, alongside its own market reading of a 70% chance of an Anthropic IPO this year. The 70% is a Kalshi market price at the time of the post, not a forecast by Anthropic or by us.

Freda Duan, who writes the Robonomics Substack, posted this on 18 October as game theory between the two labs. In her reading, OpenAI raising at $1.4 trillion (she cites Bloomberg) puts pressure on Anthropic to list at $1.5-1.6 trillion or more, and with run rates she puts at about $50 billion for OpenAI and $70 billion-plus for Anthropic, Anthropic would need to guide to $100 billion-plus to adjust for gross versus net revenue. The figures and the arithmetic are hers.

Walter Bloomberg’s 15 October 2026 relay of a D.A. Davidson note by analysts Gil Luria and Turner Dischinger, which said Anthropic’s slowing revenue growth should not be read as a broader AI demand slowdown and pointed to competition from OpenAI and open-weight models. It is Luria’s earlier read on the same growth figures this piece is built on; his 19 October CNBC segment, which CNBC titled ‘Anthropic will end up being a very speculative investment’, is summarised in the Update above.

CNBC’s 19 October 2026 post of its article casting Anthropic as the AI trade’s last big hope for a major IPO this year. The Update above summarises it: Kalshi traders’ 75% odds of an official Anthropic IPO announcement in 2026, Renaissance Capital’s count of US IPOs down 33% from 2025, and a 22V Research analyst’s quote on the $1.5 trillion valuation range.

The Arithmetic of the Step Down

By our arithmetic, the gap between the roughly $2 trillion previously expected and the around $1.5 trillion some investors discussed is about $500 billion, or 25%.

By our arithmetic, annualising the $16.8 billion third quarter gives $67.2 billion; on that simple annualisation, $2 trillion would be about 29.8 times and $1.5 trillion about 22.3 times. That is our calculation on one quarter, not a metric Anthropic or Reuters gives.

By our arithmetic from the figures Reuters gives, quarter-on-quarter growth went from more than 100% in the second quarter to 45% in the third.

The Market Around the IPO

Reuters frames the concerns against a tech selloff that is roiling global financial markets. Shares and bonds of Nvidia-backed CoreWeave tumbled on Thursday, Reuters noted, “reflecting growing investor concern about an AI buildout that is increasingly being financed with borrowed money.”

“A cooler reception for Anthropic’s IPO could weigh on the wider AI market, whose near-term prospects investors see as hinging largely on the share sale’s success, followed by OpenAI’s potential listing next year,” Reuters wrote.

Reuters also lists recent IPO setbacks: data center operator SB Energy decided to delay its listing last month, while nuclear technology company Holtec Nuclear pulled its plans to go public. Earlier on 15 October, New York City’s comptroller asked Anthropic to delay the IPO over safety and governance concerns, as we reported.

What Anthropic Has Already Disclosed

Last year Anthropic’s revenue surged twelvefold to nearly $4.6 billion, even as the company lost more than $8 billion on an operating basis, excluding writedowns of various liabilities mostly tied to previous fundraising, Reuters reported last month.

In its IPO prospectus, seen by Reuters in September, Anthropic reported a loss of $42 billion in 2025, Reuters says. The company has committed to spending at least $518 billion over a decade for cloud services, computing and infrastructure, according to Reuters.

Reuters notes that Anthropic’s growth has been underpinned by Alphabet’s Google and Amazon, which it describes as simultaneously investors, suppliers of computing power and important distribution partners, as well as AI competitors.

The Structural Read

As we read it, the step down is about the multiple, not the business shrinking: by our arithmetic, on a simple annualisation of the $16.8 billion quarter, $2 trillion is about 29.8 times and $1.5 trillion about 22.3 times that figure, while Reuters reports revenue still rose 45% in the quarter.

As we read it, the financing backdrop is part of the price: Reuters ties the investor caution to a selloff in which shares and bonds of Nvidia-backed CoreWeave tumbled, reflecting concern about an AI buildout increasingly financed with borrowed money.

As we read it, the commitments Reuters lists explain why the growth rate matters: Anthropic has committed to spending at least $518 billion over a decade for cloud services, computing and infrastructure, according to Reuters, against revenue of nearly $4.6 billion last year.

Three Implications

ANTHROPIC Reuters says Anthropic did not immediately respond to requests for comment; the November share sale and its terms have not been set out in anything we read.

IPO INVESTORS Some investors who attended the investor day discussed a valuation of around $1.5 trillion, three of the people told Reuters, down from the roughly $2 trillion previously expected.

THE AI MARKET Reuters reports that investors see the wider AI market’s near-term prospects as hinging largely on the share sale’s success, followed by OpenAI’s potential listing next year.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Capex Map & The State of AI Hyperscalers.

The framework sets out to explain “How the money flows, where it cracks, what it buys, who can absorb it, and what happens when revenue can’t catch up.”

As we read it, an IPO valuation is where that question gets a price: the $1.5 trillion some investors discussed, per Reuters, is a market read on whether revenue growing 45% a quarter keeps pace with at least $518 billion of commitments. The framework predates the report and does not discuss Anthropic’s IPO.

Anthropic quarterly revenue per Reuters: Q2 2026 $11.6 billion, Q3 2026 $16.8 billion
Anthropic’s revenue rose 45% to $16.8 billion in the third quarter, after more than doubling from the first quarter to $11.6 billion in the second, according to people familiar with the matter cited by Reuters on 15 October 2026.

What Is Not Established

Nothing we read sets an IPO price or valuation range from Anthropic itself. The $1.5 trillion and $2 trillion figures come from people familiar with the matter, as reported by Reuters, and are both approximate.

Reuters says some investors discussed the lower figure; it does not say how many, or whether Anthropic or its underwriters have changed the terms of the November share sale. Anthropic had not responded to Reuters at the time of its report.

The Bottom Line

Some Anthropic investors discussed a valuation of around $1.5 trillion for the IPO, down from the roughly $2 trillion previously expected, after Anthropic told them third-quarter revenue rose 45% to $16.8 billion, Reuters reported, citing people familiar with the matter.

By our arithmetic, the step down is about $500 billion, or 25%.
