On June 1, 2026, Anthropic quietly filed a confidential draft registration statement with the US Securities and Exchange Commission, setting the stage for one of the most consequential public market debuts in the history of artificial intelligence (source: CNBC). The company is targeting an October 2026 listing, with analysts widely expecting a debut valuation of around $1 trillion.
What makes this IPO unusual is not just the scale, but the contradiction at the heart of it. Anthropic was founded on the belief that advanced AI could pose an existential risk to humanity, and yet now it is preparing to raise the largest sum in AI history to build more of it, and asking the public to come along for the ride.
In this article, we will break down what Anthropic is, how its business actually works, what you need to know before the IPO, and what you should actually be thinking about after it goes live.
What is Anthropic?
Anthropic is an American artificial intelligence safety company founded in 2021 and headquartered in San Francisco, California. Its primary product is Claude, a family of large language models used by developers, businesses, and consumers for tasks ranging from writing and analysis to coding and customer service.
Unlike many AI companies that treat safety as a constraint on capability, Anthropic has built its identity around the idea that making AI safe and making it useful are the same problem. Whether that philosophy translates into a durable competitive advantage is one of the central questions hanging over its IPO.
In May 2026, Anthropic announced that it generated $47 billion in annual revenue, up from $10 billion last year. It is on track to report its first profitable quarter in Q2 2026, with analysts projecting approximately $10.9 billion in revenue (source: CNBC).
The founding story: Why 7 employees left OpenAI
In late 2020 and early 2021, a group of senior researchers at OpenAI grew increasingly uncomfortable with the direction the company was taking. One faction within OpenAI believed that scaling models as fast as possible was both the path to AGI and an acceptable risk to take. Another faction, led by Dario Amodei, who was then OpenAI’s Vice President of Research, believed that the faster you scaled, the more important it became to understand and control what you were building.
That disagreement, combined with concerns about OpenAI’s increasing commercialization and the influence of its investors, led to a rupture. In January 2021, Dario Amodei, his sister Daniela Amodei (then Vice President of Safety), and five other OpenAI colleagues resigned and founded Anthropic (source: Wikipedia). The founding team included Jared Kaplan, the co-author of the neural scaling laws that provide the foundation for modern AI development, and Chris Olah, widely regarded as one of the most foremost researchers in AI interpretability.
They raised $124 million in their first funding round and set out to build an AI lab where safety research was not a department sitting alongside the main work, but the main work itself.
The irony that a company founded on fears about AI’s dangers is now approaching a $1 trillion public listing is not lost on anyone. The working logic, which Dario Amodei has articulated across interviews and public writing, is that powerful AI is coming regardless of what any single company decides to do (source: Dario Amodei). Given that, he argues that it is better to have safety-focused researchers at the frontier than to step back and let others build it without those guardrails. Whether that reasoning holds up under the scrutiny of public markets is one of the more interesting questions the IPO will force into the open.
How Anthropic makes money
Anthropic’s commercial products are built around Claude, its underlying AI model, but they take several distinct forms: Claude.ai, Claude Code, Claude Cowork, and Claude Security. Despite having four products, Anthropic’s revenue comes primarily from enterprise. Over 1,000 customers spend over $1 million a year on Claude. This is an increase from just a dozen two years ago, with that number doubling in under two months as reported in April 2026 (source: Anthropic). Enterprise customers pay on a per-token basis through the Claude API, meaning revenue scales directly with usage.
The standout product is Claude Code, which is Anthropic’s agentic coding tool designed for developers. It generated $2.5 billion in annualized revenue this year alone, with Claude Code accounting for 51% of all enterprise generative AI usage (source: MindStudio).
A large share of that enterprise revenue comes from two relationships. Firstly, Amazon is both an investor and a sales channel. It previously already invested $8 billion in Anthropic, and made a new investment of $5 billion committed in April 2026, with up to $20 billion more pledged (source: Anthropic). Its sales channel has over 100,000 businesses now running Claude through Amazon Bedrock.
Secondly, Google holds approximately 14% of Anthropic and has plans to invest up to $40 billion in the company, with the first $10 billion already committed, and the remaining $30 billion is tied to specific performance milestones (source: CNBC). As part of the agreement, Anthropic’s flagship models are natively integrated and offered to enterprise users via Vertex AI.
Having the two largest cloud providers simultaneously funding the company and selling its product is a structural advantage that is difficult for any competitor to replicate.
Why is everyone watching the Anthropic IPO?
It could be the first pure AI safety company to go public at a trillion-dollar valuation
Anthropic is not just an AI company. It is the only major AI lab that has placed safety research at the center of its commercial strategy. Going public at or above $1 trillion would send a signal that the market believes responsible AI development is not just a PR stance but a viable and valuable business model.
Its revenue trajectory is extraordinary
Anthropic grew from $1 billion in annualized revenue in December 2024 to $47 billion in May 2026, a 47-fold increase in 18 months (source: SaaStr). Even accounting for the broader AI investment boom, that growth rate is unusual by any measure.
It just overtook OpenAI
Anthropic’s Claude surpassed OpenAI’s ChatGPT in enterprise adoption in early 2026. As of May 2026, 34.4% of businesses use Claude, compared to 32.3% for OpenAI, and Anthropic is winning 70% of new enterprise deals (source: VentureBeat). For a company that was barely second just a year ago, this is significant.
The AI IPO wave is making history
Anthropic is filing alongside SpaceX and ahead of OpenAI’s anticipated listing, making 2025 an unprecedented year for technology public offerings. The combined attention being paid to this IPO class is drawing in a broader pool of investors than any single company could attract alone.
What you need to know before the Anthropic IPO
No price or date has been set yet
Anthropic’s filing is confidential, which means the company has submitted its S-1 to the SEC for review but has not yet published the document or set a share price, share count, or firm listing date. The targeted window is around October 2026, though timelines for listings of this size frequently shift based on the market conditions.
The current valuation is $965 billion
Anthropic’s most recent private valuation, set during its $65 billion Series H funding round, was approximately $965 billion (source: Yahoo Finance). Analysts expect the public debut to push that above $1 trillion, though none have officially confirmed a target.
The Public Benefit Corporation structure
Anthropic is incorporated as a Public Benefit Corporation rather than a standard C-corporation. A PBC is required to balance profit with a defined public benefit, which in Anthropic's case is the responsible development of AI for the long-term benefit of humanity. Anthropic has also established a Long-Term Benefit Trust, designed to protect the company's safety mission even as public shareholders enter the picture (source: Anthropic).
For investors, this structure may pose concerns as it limits how aggressively Anthropic can be pushed to maximise short-term profit at the expense of its stated mission, and it gives the company a legal basis to resist activist shareholder pressure. It also means that public investors are buying into a company where certain decisions may be made on safety grounds that a purely profit-driven company would not make.
Anthropic warned of AI’s own risks in its IPO filing
Anthropic included explicit warnings in its S-1 about the potential dangers of the technology it is building. The company stated that AI development poses risks to society that the company itself may not be able to fully mitigate. This kind of disclosure is rare, and it reflects the tension at the core of the business: Anthropic is asking investors to fund the development of something it openly acknowledges could be dangerous (source: CNBC).
Is the Anthropic IPO overvalued? What the bears are saying
The bull case for Anthropic is straightforward: it is among the fastest-growing software companies in recent history, it is the enterprise AI market leader, and it is about to report its first profitable quarter. The bull case is harder to dismiss.
The AI bubble comparison
Neil Wilson, an analyst from Saxo UK, suggested that the AI bubble is real, and drew a parallel to the late 1990s dotcom boom (source: The Guardian), where companies with extraordinary growth rates and compelling narratives went public at valuations that proved impossible to sustain once growth normalized.
Anthropic, SpaceX, and OpenAI are together valued at close to $4 trillion, and all three are losing more money than they make (source: Al Jazeera). Critics argue that the offerings could reshape the AI trade in the stock market as new listings may reduce the scarcity value and pull capital away from existing AI beneficiaries (source: Business Insider).
The compute cost problem
Anthropic spends heavily on computing infrastructure to train and run its models. Although its revenue is now growing faster than compute costs, the company's profitability is narrow and depends heavily on maintaining that relationship. Any shifts in the competitive landscape, such as a rival releasing a significantly cheaper or more capable model, could force Anthropic to increase spending to keep pace, which will compress margins quickly.
OpenAI is not going away
Despite falling behind on enterprise adoption, OpenAI retains a massive consumer user base through ChatGPT and is targeting its own public listing in late 2026 or early 2027. The two companies are in a direct race for the same enterprise contracts, and OpenAI has its own deep relationships with Microsoft and a larger brand recognition advantage with the general public. As such, the competitive dynamics could shift again.
The mission and market may eventually conflict
Anthropic's PBC structure protects its safety mission from short-term shareholder pressure. However, once public markets are involved, the pressure to grow faster, reduce costs, and compete more aggressively may intensify. Investors should think carefully about what happens when the market demands growth rates that the Long-Term Benefit Trust would complicate.
What happens after the Anthropic IPO?
S&P 500 inclusion could come earlier than SpaceX
Unlike SpaceX, which posted a $4.94 billion net loss in 2025 and faces a lengthy wait for S&P 500 inclusion (source: Reuters), Anthropic is on track to demonstrate GAAP profitability in Q2 2026. This means that Anthropic has a slight headstart in being included in the S&P 500, though it will still need to complete the 12-month public trading requirement before qualifying. However, if profitability holds, Anthropic could be eligible for S&P 500 consideration as early as late 2027, triggering significant mandatory passive buying from index funds.
The impact of Google and Amazon
Both Google and Amazon hold large stakes in Anthropic that will become publicly tradeable after the IPO lock-up period expires. Google's 14% stake could be worth over $140 billion at a $1 trillion valuation. Amazon's stake, on the other hand, implies a position worth $135 to $160 billion (source: Yahoo Finance). Neither company is likely to sell large quantities immediately, as both depend on Anthropic commercially. But the sheer size of these positions means the eventual lock-up expiry is worth monitoring closely.
OpenAI’s IPO impact on Anthropic
When OpenAI eventually goes live with its IPO, it will create a direct publicly-traded peer comparison for Anthropic. This can result in two different scenarios. On one hand, a successful OpenAI listing could lift the entire AI sector. On the other hand, if OpenAI prices at a valuation that makes Anthropic look expensive by comparison, or if OpenAI's public financials reveal uncomfortable similarities in the economics of training and running frontier AI models, it could put downward pressure on Anthropic's stock.
Revenue growth will be scrutinized quarter by quarter
Anthropic's valuation is almost entirely justified by its growth rate. Going from $1 billion to $47 billion in annualized revenue in 18 months is the core of the bull case (source: SaaStr). The moment that growth rate decelerates meaningfully, the multiple the market is willing to pay may decrease. Public investors will have access to quarterly earnings that private investors did not, which means both the upside and the downside of the growth story become more visible after the IPO.
Are there any alternatives to the Anthropic IPO?
If the valuation or the timing is giving you some hesitation, here are some ways to think about getting exposure to the same themes without buying Anthropic at IPO.
Nvidia (NVDA)
If your view is that AI is going to keep growing but you are unsure which lab wins, Nvidia is the most direct expression of that thesis. Every major AI company, including Anthropic, runs on Nvidia GPUs. Nvidia commands over 90% of the AI accelerator market as of 2026 (source: Introl), with data centre revenue reaching a record $75.2 billion in its Q1 fiscal 2027 (source: Nvidia). The company does not need to pick a winner in the AI lab race to grow. It just needs overall demand for AI infrastructure to keep rising.
Microsoft (MSFT)
Microsoft's relationship with OpenAI gives it the most direct exposure to Anthropic's primary competitor, but the broader point is that Microsoft has already embedded AI into products that hundreds of millions of people use every day. Its AI business has reached an annual revenue run rate of $37 billion, an increase of 123% year over year (source: Microsoft), with Copilot paid seats now exceeding 20 million (source: GeekWire). For investors who are looking for enterprise AI exposure at a lower valuation risk, Microsoft is worth considering.
Amazon (AMZN) and Alphabet (GOOG)
If you’re looking to still have some exposure to Anthropic, Amazon and Google are worth considering. Amazon holds a stake in Anthropic estimated at $135 to $160 billion and serves as its primary cloud partner. Google holds approximately 14% of Anthropic and has committed up to $40 billion in additional investment. Buying either stock does give you indirect Anthropic exposure at a lower valuation multiple. However, both companies are also Anthropic's cloud infrastructure providers, which means that their financial health is partially tied to Anthropic's continued growth. It is less a hedge than a correlated bet, which is worth understanding before assuming you are getting diversified exposure.
Waiting for the OpenAI IPO
The most direct alternative for investors who specifically want AI lab exposure is OpenAI, which is targeting a public listing in late 2026. OpenAI has a larger consumer audience, a deeper Microsoft partnership, and a different philosophy about the relationship between capability and safety. Anthropic is the enterprise leader, the safety-first brand, and the more recently profitable company. If you are unsure which AI lab approach you believe in more, waiting for both to be publicly listed before committing capital to either would be more reasonable.
What should you actually do after the Anthropic IPO?
If you are a trader
Anthropic's IPO is not happening until around October 2026, and no pricing details have been confirmed. The trading opportunity around the listing will depend heavily on how the broader AI market is performing by that point, and whether the SpaceX and OpenAI listings before it have gone well or badly. Before making a move, you may want to observe how the AI IPO class as a whole is received. If SpaceX has pulled back significantly from its June listing and sentiment toward AI valuations has cooled, Anthropic's opening could be more volatile than currently expected. If the sector remains hot, momentum traders will likely have a narrow but real window on listing day.
If you are a long-term investor
Anthropic has not set a price, which means you have more time to evaluate the numbers before making a decision. When the S-1 is made public, you should read it carefully. Pay specific attention to compute costs as a percentage of revenue over time, customer concentration, and any disclosures about the relationship between the PBC structure and shareholder rights.
There are three things worth watching in the months following the IPO:
Whether Anthropic sustains profitability beyond its first profitable quarter in Q2 2026
How Google’s and Amazon’s stakes are disclosed and what the lock-up timelines look like
Whether OpenAI's listing creates a cleaner peer comparison that either validates or challenges Anthropic's valuation
In the long term, it is possible for Anthropic to do well: Enterprise AI is not going away, safety-focused AI development may prove to be a durable differentiator as regulation increases, and the company has a revenue trajectory that is genuinely remarkable. The concern is not whether Anthropic is building something valuable, but rather whether the IPO price reflects what it is worth today, or what its most optimistic supporters hope it becomes.
Closing thoughts
Anthropic's IPO is unlike anything that has come before it in the technology sector: a company that openly warns about the risks of its own products, structured legally to resist short-term profit pressure, run by researchers who left the most famous AI lab in the world because they thought it was moving too fast. The fact that it is now heading toward a $1 trillion public listing is either the ultimate validation of that philosophy or the ultimate irony of it.
As the listing is still months away, you can spend the time to do your own research so that you don’t get swept up in the narrative. Look out for the S-1 as well as the first few quarterly earnings after the IPO, both of which will tell you more than any analyst note.
