Anthropic Stock: IPO Date, Valuation, and How to Invest (2026)

Is Anthropic Publicly Traded?

No. As of October 20, 2026, Anthropic, PBC is a private company. Its shares do not trade on any exchange, it has no ticker, and no brokerage account can buy its common stock.

On June 1, 2026, Anthropic said it had confidentially submitted a draft registration statement on Form S-1 to the SEC for a proposed IPO of its common stock. It said the number of shares and the price had not been set, and that any offering would depend on the SEC's review, market conditions, and other factors.

A search of the SEC's EDGAR database on October 20, 2026 found no public S-1 from Anthropic. Under SEC staff policy for confidential drafts, a company must file its registration statement publicly at least 15 days before it starts a roadshow. Anthropic's audited financials will therefore be public at least 15 days before formal marketing to investors begins.

The facts on this page come from dated public sources, and this page does not recommend buying or selling any security.

Anthropic IPO Date: What Has Been Reported

Anthropic has not announced an IPO date. Everything beyond the June 1 filing comes from press reports that cite unnamed people, and the reported timing has already moved from October to November.

• • June 3, 2026: Bloomberg reported that Anthropic picked Morgan Stanley and Goldman Sachs to lead the offering, with JPMorgan Chase also working on the deal, and that a listing as soon as October was under consideration.
• • August 20, 2026: Bloomberg reported that Citigroup was set to join the top tier of banks on the deal.
• • September 13 to 14, 2026: Bloomberg and CNBC reported that Anthropic had chosen Nasdaq as its listing venue.
• • Late September 2026: Reuters reported details from a draft prospectus it had reviewed, including 2025 revenue of nearly $4.6 billion and a net loss of about $42 billion.
• • October 1, 2026: Bloomberg reported that Anthropic was aiming to list as soon as mid-November, with marketing possibly starting the week of November 9.
• • October 14 to 15, 2026: Anthropic held an investor day in San Francisco. Reuters reported that it told prospective investors third-quarter revenue rose 45% from the prior quarter to $16.8 billion, and that some attendees discussed a valuation of around $1.5 trillion, below the roughly $2 trillion floated earlier.

What Anthropic Has Not Confirmed

Anthropic has not confirmed the exchange, the banks, the timing, the offering size, or the valuation in any of the reports above. Treat them as reported plans that can change with the SEC review, market conditions, or the company's own decision.

Reports of the amount Anthropic might raise have varied widely and none has been confirmed, so this page leaves that figure out. The public S-1 and its amendments will state the share count, price range, and exchange.

Anthropic Stock Ticker and Stock Price

Anthropic has not announced a ticker symbol. The exchange and ticker normally appear in the public S-1 or a later amendment. Symbols that data sites show for private companies, such as Yahoo Finance's ANTH.PVT page, are tracking labels, not exchange tickers.

There is also no Anthropic stock price. Anthropic's funding announcements state a post-money valuation for each round, not a price per share. Prices quoted on crypto platforms for Anthropic tokens or contracts are prices for those products, covered below, and not for Anthropic shares.

Private-round valuations and an IPO price are not directly comparable. Investors in private rounds, such as Amazon, hold preferred stock with negotiated rights, while the proposed IPO is of common stock.

Anthropic Valuation History

Anthropic's post-money valuation rose from $61.5 billion in March 2025 to $965 billion in May 2026, more than 15 times in about 15 months, across four priced rounds.

The Series H total included $15 billion that hyperscalers had committed earlier, including $5 billion from Amazon, so not all of the $65 billion came from the round's lead investors.

Anthropic's Business and Revenue

Anthropic was founded in 2021 and sells access to its Claude models. It earns revenue from Claude subscriptions for consumers and businesses, Claude Code for software development, and its API, which is also offered through AWS, Google Cloud, and Microsoft Azure. Its newest models as of October 2026 are Claude Opus 5.5 (September 22), Sonnet 5.5 (September 28), and Haiku 5.5 (October 7).

Anthropic reports growth as run-rate revenue, its current revenue pace annualized. The company's own figures:

• • About $1 billion at the start of 2025, rising to over $5 billion by August 2025 (Series F announcement, September 2, 2025).
• • About $9 billion at the end of 2025 (Amazon compute announcement, April 20, 2026).
• • $14 billion on February 12, 2026, when more than 500 customers were spending over $1 million a year with Anthropic (Series G announcement).
• • Above $30 billion by April 20, 2026 (Amazon compute announcement).
• • Above $47 billion in May 2026 (Series H announcement, May 28, 2026).

Anthropic's Reported Financials

Run-rate is not reported revenue. Reuters, citing the draft prospectus and the October investor day, reported revenue of nearly $4.6 billion for 2025, twelve times the prior year. It then reported $4.7 billion in the first quarter of 2026, $11.6 billion in the second, and $16.8 billion in the third.

Reuters also reported that Anthropic lost more than $8 billion on an operating basis in 2025, and that its net loss of about $42 billion was mostly charges tied to earlier fundraising. It reported that the company described itself as profitable on an adjusted basis in the third quarter of 2026.

Two other reported figures matter for risk. Two customers accounted for nearly a quarter of 2025 revenue, and Anthropic has committed at least $518 billion over about a decade to cloud services, computing, and infrastructure. These numbers are from press reports of a draft document, and the public S-1 may differ.

Who Owns Anthropic: Amazon, Google, and Other Investors

Amazon is the largest disclosed strategic investor. Its 10-Q for the quarter to June 30, 2026 says it invested $8.0 billion in Anthropic convertible notes from 2023 through 2025, then $5.0 billion in Series G and $5.0 billion in Series H nonvoting preferred stock in the second quarter of 2026. Amazon also set up a financing facility of up to $20 billion that becomes available as Anthropic meets compute delivery milestones, with $15 billion still available after the Series H investment.

At June 30, 2026, Amazon put the fair value of its Anthropic convertible notes at about $97.9 billion and the carrying amount of its nonvoting preferred stock at about $92.5 billion. It recorded about $50.5 billion of upward adjustments on the preferred stock in the second quarter alone, in other income rather than operating income.

Google first invested in 2023. On April 24, 2026, TechCrunch reported, citing Bloomberg and Anthropic, that Google committed $10 billion at a $350 billion valuation, with up to $30 billion more if Anthropic hits performance targets. Alphabet does not name Anthropic in its 10-Q. It reported $124.3 billion of non-marketable equity securities under the measurement alternative on June 30, 2026, a figure that covers many private holdings, not only Anthropic.

On November 18, 2025, Microsoft and Nvidia committed to invest up to $5 billion and up to $10 billion respectively. The Series H named financial investors including Capital Group, Fidelity, T. Rowe Price, Baillie Gifford, Blackstone, GIC, and Temasek, plus Micron, Samsung, and SK hynix as strategic infrastructure partners.

On October 18, 2026, Anthropic said that, subject to stockholder approval, 5% of its shares would be committed to a new public benefit fund, with 2% more at the board's discretion for every 50% rise in the company's value above a set baseline.

How to Buy Anthropic Stock Before the IPO

You cannot buy Anthropic shares in a brokerage account until it lists. Every route before then is indirect, partial, or restricted, and each carries risks that a listed share does not.

Anthropic's help center, last updated June 29, 2026, says its bylaws make any sale or transfer of its stock, or of any interest in its stock, void unless its board has approved it. A buyer in an unapproved deal would not be recognized as a stockholder. That rule shapes every option below.

Option 1: Amazon and Alphabet Shares

Amazon and Alphabet are listed companies with large Anthropic positions, so their shares carry some Anthropic exposure. That exposure is diluted by everything else they own, and their results are driven mainly by retail, cloud, and advertising. At Amazon, Anthropic gains are booked in other income, not operating income.

Risks: the stakes are valued using private-round prices and models, which Amazon classifies as Level 3 fair value measurements, and a lower IPO price could reverse recent gains. Both companies also supply Anthropic's computing capacity and compete with it in AI models. Microsoft and Nvidia committed to invest as well, but Anthropic is a small part of either company.

Option 2: Funds That Hold Private Anthropic Shares

Some public funds hold private Anthropic stock. KraneShares says its AGIX ETF invested directly on Anthropic's capitalization table in February 2025 and had a 2.91% allocation as of April 15, 2026. Scottish Mortgage Investment Trust reported on April 27, 2026 that Anthropic made up 2.5% of its total assets after a revaluation.

Large managers that took part in Anthropic's rounds, such as Fidelity, T. Rowe Price, and Capital Group, may hold positions in specific funds. Check a fund's latest holdings report, not its name. Harbor's Anthropic AI Lab Ecosystem ETF (ANTW), launched August 12, 2026, states that it is not affiliated with Anthropic, and its largest holdings on October 19, 2026 were Alphabet, TeraWulf, Amazon, and Microsoft.

Risks: the Anthropic weight in these funds is small, private holdings are valued by estimate rather than market price, and investment trusts can trade at a premium or discount to the value of what they hold.

Option 3: Secondary Markets for Private Shares

Platforms that match buyers and sellers of private company stock are generally limited to accredited investors. For US individuals, that means income above $200,000 ($300,000 with a spouse or spousal equivalent) in each of the last two years, net worth above $1 million excluding a primary residence, or holding a Series 7, 65, or 82 license.

Anthropic restricts these trades tightly. Its help center says it does not permit special purpose vehicles (SPVs) to acquire its stock, that transfers to an SPV are void, and that offers to invest in its past or future rounds through an SPV are prohibited. It warns that funds claiming indirect access likely rely on ways to get around its transfer restrictions.

On October 20, 2026, an EDGAR company search returned 35 entities with Anthropic in their names, mostly series of private funds, and every one had filed only Form D notices of exempt offerings. A vehicle's name says nothing about what it owns or whether Anthropic approved the transfer.

• • Red flags Anthropic lists: unsolicited offers, claims of exclusive or limited-time access, requests for crypto or wire payments, pressure to invest quickly, and no proof of board approval.
• • Anthropic says it does not issue stock certificates to the general public, and it names Unicorns Exchange as not authorized to buy or sell its shares.

Option 4: Tokenized Pre-IPO Products Are Not Shares

Some crypto platforms sell tokens or contracts that track an estimated Anthropic value. PreStocks, which said in April 2026 that its pre-IPO tokens were live in the Binance app, offers an Anthropic token. It says its tokens are backed 1:1 by SPV exposure, confer no ownership, voting, dividend, information, or other legal rights, and are not available to US persons. Binance Futures separately listed a cash-settled Anthropic pre-IPO perpetual contract, a leveraged derivative, in June 2026.

Structure risk: Anthropic says it does not permit SPVs to acquire its stock, and that any third party selling its shares to the public, including through tokenized securities, is likely offering an investment that may have no value. If the vehicle behind a token never validly held shares, the backing may not exist.

Counterparty risk: SEC staff said on January 28, 2026 that third-party tokenized securities may not give holders any rights as holders of the underlying security, and that holders may be exposed to the third party's own risks, such as bankruptcy. A synthetic product or security-based swap gives no equity, voting, or information rights at all.

• • Price gap: token and contract prices reflect trading on that platform, not a transaction in Anthropic stock, and can sit far from any IPO price.
• • Conversion: there is no assurance that a token turns into listed Anthropic shares after an IPO or pays out at the IPO price.
• • Leverage: perpetual futures can be liquidated on short price moves, and funding payments add cost over time.
• • Protections: these products are generally not offered to US persons, and the protections of a regulated US broker may not apply.

What to Watch in Anthropic's S-1

When Anthropic files publicly, the S-1 will replace press reports with audited numbers. Our IPO investing guide, linked below, explains how to read a prospectus section by section. For Anthropic, these items matter most:

• • Revenue quality: the split between API usage and subscriptions, customer concentration (Reuters reported two customers made up nearly a quarter of 2025 revenue), and how much revenue sits under long-term contracts.
• • Compute costs and commitments: what training and serving Claude costs as usage grows, and how much of the reported $518 billion in commitments cannot be cancelled.
• • Profit measures: the gap between GAAP results and the adjusted profit reported for the third quarter of 2026, and what the adjustments are.
• • Share classes and control: Anthropic's Long-Term Benefit Trust holds Class T stock that lets it elect board members, and press reports on the draft describe added share classes that concentrate voting power with the co-founders. The S-1 will show how much say common shareholders get.
• • Related parties: the terms of Amazon's and Google's investments and compute deals, including Amazon's facility, which can be drawn in common stock after an IPO.
• • Offering terms: shares sold, price range, use of proceeds, selling shareholders, and lockup periods for existing holders.
• • Risk factors: Fortune, citing the Financial Times, reported that more than a third of the draft covers risks, including AI safety risks.

Risks of an Anthropic IPO for Investors

The case for Anthropic rests on fast revenue growth and wide enterprise use of Claude. The risks are as large, and they are listed here with the same weight.

• • Valuation: at the reported $1.5 trillion to $2 trillion, Anthropic would be valued at roughly 22 to 30 times its third-quarter 2026 revenue annualized. This is simple arithmetic on reported figures, not a view on fair value.
• • Losses and spending: the reported 2025 operating loss topped $8 billion, and the reported compute commitments of at least $518 billion run for about a decade.
• • Slowing growth: reported quarter-over-quarter revenue growth slowed from about 147% in the second quarter of 2026 to 45% in the third, which Reuters reported disappointed some investors.
• • Competition: OpenAI, Google, and other labs compete on price and model quality, and Fortune reported, citing Reuters, that many large customers do not have long-term contracts.
• • Partner dependence: Amazon and Google are investors, compute suppliers, and competitors at the same time.
• • IPO mechanics: most IPO shares go to institutions, first-day trading can be volatile, and lockup expiries can add supply months after listing.
• • Governance: as a public benefit corporation with a Long-Term Benefit Trust, Anthropic weighs its mission alongside shareholder returns, and outside shareholders may have limited voting power.
• • Timing: the IPO may slip or not happen. Anthropic has said the offering depends on market conditions and other factors.
