Something big is brewing in the world of artificial intelligence. A handful of Anthropic’s existing investors have told reporters they expect the company behind Claude to go public as early as October 2026 at a valuation of more than $2 trillion. A few even sketch out a path to $3 trillion. If those numbers hold, the listing would top the recent SpaceX debut and become the largest IPO in history.

 

This is not an official company target. Anthropic’s management has not locked in a specific valuation. The figures come from backers who have watched the company’s revenue climb at a pace almost no one predicted. The conversation raises straightforward questions for anyone following tech markets: How did a five-year-old lab reach this point? What is driving the optimism? And what could still go wrong?

 

By the end of this piece, you will understand the revenue story behind the forecasts, the risks investors themselves flag, and why public markets may soon put the AI boom to its biggest test yet.

Anthropic started in 2021 when a group of researchers left OpenAI to build AI systems with a stronger focus on safety and reliability. The company is best known for its Claude family of models. Claude has found particular traction with businesses that want powerful language tools for coding, analysis, and internal workflows rather than pure consumer chatbots.

 

From the beginning, the founders positioned Anthropic as a lab that would treat careful development and long-term risk management as core priorities, not afterthoughts. That stance helped the company attract talent and capital even as the broader AI race accelerated.

The May 2026 Funding Milestone

In May 2026 the company closed a massive funding round that valued it at $965 billion. That figure already put Anthropic ahead of OpenAI on paper for the first time. Around the same time, Anthropic said its annualized revenue run-rate had crossed $47 billion. Annualized run-rate is simply a way of taking recent monthly performance and multiplying it by twelve to estimate a full-year pace. 

 

It is not the same as actual booked revenue for a calendar year, but it is the metric the company and its investors prefer when talking about growth speed. The jump in valuation reflected both the rapid adoption of Claude inside large organizations and the intense private-market demand for stakes in frontier AI labs. Investors poured in tens of billions of dollars during that round, giving the company substantial resources to expand computing capacity and continue model development.

Investor Expectations for the IPO

Six existing investors later told the Financial Times they believe that same revenue engine can push the company past $2 trillion in a public listing this autumn. One went further, arguing that if the growth rate stays near 800 percent, a conservative 30x revenue multiple on $100 billion to $120 billion in annualized sales could justify a valuation closer to $3 trillion. 

 

Those are investor opinions, not management guidance. Still, the scale of the claims has forced the market to pay attention. The projections rest on the assumption that enterprise demand for Claude will continue to climb at an exceptional pace through the rest of 2026. Backers point to the company’s focus on practical business tools as a key reason they expect the revenue trajectory to continue.

Setting a New IPO Record

SpaceX went public in June 2026 at about $1.77 trillion and raised a record $75 billion. An Anthropic listing at $2 trillion or higher would rewrite the record books again. The comparison is useful because it shows how quickly the ceiling for technology IPOs has risen. Just a few months after SpaceX set the previous high-water mark, Anthropic’s private investors are already discussing numbers that would surpass it.

 

Whether public markets ultimately accept those figures will depend on the detailed financial disclosures that appear in any future registration statement and on the broader appetite for AI stocks at the time of the offering. For now, the conversation itself signals how large the stakes have become in the race among leading AI companies.

The Explosive Run-Rate Climb

The single biggest reason investors are willing to talk in trillion-dollar terms is the speed of Anthropic’s top-line expansion. At the end of 2025, the company’s annualized run rate was near $9 billion. By February 2026, it had reached $14 billion. March brought $19 billion. April hit $30 billion. By mid-May, the figure stood above $47 billion.

 

That sequence of jumps is striking when laid out month by month. In roughly five months, the annualized pace more than quintupled. Few software companies of any size have ever posted this kind of acceleration once they already operated at a multi-billion-dollar scale. The numbers themselves come from Anthropic’s preferred method of describing growth: taking recent monthly performance and multiplying it by 12. While this run rate is not the same as total revenue booked over a full calendar year, it has become the key metric that both the company and its investors use to track momentum.

What’s Driving the Acceleration

That kind of trajectory is rare even in software. Much of the recent acceleration has come from enterprise customers and from Claude Code, the company’s agentic coding tool. Businesses are embedding Claude into their own products and paying for usage at scale. Consumer subscriptions make up a smaller slice of the total.

 

Large organizations appear to be treating Claude less like an experimental chatbot and more like core infrastructure for coding, analysis, and internal workflows. When companies integrate the models deeply into daily operations, usage tends to compound rather than stay flat. 

 

Claude Code, in particular, has helped turn abstract model capability into concrete developer productivity, which in turn drives higher token consumption and larger enterprise contracts. The result is a revenue mix tilted heavily toward high-volume commercial customers rather than individual users.

Forward Projections and the $3 Trillion Math

Looking ahead, the same investors who spoke to the Financial Times expect the annualized run-rate to land between $100 billion and $120 billion by the end of 2026. That would represent more than a tenfold increase across a single calendar year. One backer put the growth rate at roughly 800 percent and suggested that such momentum could support a 30-times revenue multiple, producing a $3 trillion valuation at the high end of the revenue range.

 

The arithmetic is straightforward. If the company reaches the upper end of those projections and public investors are willing to pay thirty times that revenue figure, the implied market value lands near $3 trillion. Even the more modest $2 trillion target that several investors discussed would still require the market to assign a rich multiple to a business that is still private today. These projections remain the views of existing shareholders rather than official company guidance, yet they illustrate how tightly the valuation conversation is tied to the continuation of the current growth curve.

How the Multiples Compare

Public-market comparisons are imperfect because Anthropic has no direct U.S.-listed peer. Investors have looked at companies that benefit from AI spending, such as Palantir and Nebius, which have traded around 55 times revenue this year. On that basis, a $2 trillion valuation against the May $47 billion run-rate works out to roughly 43 times sales, below the multiples some AI-linked stocks already command.

 

The comparison is useful mainly as a reference point. It shows that the $2 trillion figure some backers discuss is not wildly out of line with how certain public AI-related names have been priced in 2026. At the same time, the absence of a true peer means any multiple applied to Anthropic remains more art than science until the company trades publicly and reports full financial results.

The Critical Assumption

Of course, multiples shrink when growth slows. The entire bull case rests on the assumption that the current pace continues long enough for the IPO to price on those elevated numbers. 

 

If the run-rate expansion moderates before a public listing, the valuation math that supports $2 trillion or $3 trillion would need to be revised downward. For now, the revenue trajectory remains the central pillar of the optimistic case.

Several factors make the optimistic case feel plausible to the people already holding Anthropic equity. These advantages do not guarantee a $2 trillion or $3 trillion outcome, but they help explain why some existing shareholders remain willing to project valuations well above the company’s most recent private mark.

Product-Market Fit Inside Enterprises

First is product-market fit inside enterprises. Claude has carved out a reputation for reliability and coding strength. When large companies start spending serious money on AI tools, they tend to stick with the systems that solve real workflow problems. That stickiness shows up in the revenue numbers.

 

Enterprises rarely switch core tools lightly once they have trained staff, integrated systems, and built internal processes around a particular model. Claude’s strength in coding and practical business tasks has helped it move beyond experimental pilots into more permanent deployments. 

 

For investors, this kind of embedded usage is valuable because it suggests revenue is more durable than the short-term spikes sometimes seen in pure consumer applications. The deeper Claude is embedded in daily operations, the harder it becomes for competitors to displace it quickly, even if newer models appear with lower prices or different features.

A Deep Funding Base

Second is the funding base itself. Nearly $100 billion flowed into Anthropic in 2026 alone from venture firms, sovereign wealth funds, and strategic partners. Amazon has committed large sums in exchange for cloud usage. Chip and infrastructure partners have also taken stakes. The capital gives the company room to keep training bigger models and expanding data-center capacity.

 

Access to this level of capital matters for a frontier AI company. Training advanced models and running them at scale requires enormous computing resources. Having committed partners and large cash reserves reduces the risk that Anthropic will be forced to slow development simply because it cannot afford the next training run or the next wave of servers. 

 

Strategic investors who also supply cloud capacity or chips create additional alignment: their success is partly tied to Anthropic’s continued growth. For existing shareholders, this deep funding base provides both a financial buffer and a signal that sophisticated institutions continue to see long-term potential.

Favorable Timing for a Public Listing

Third is timing. Anthropic filed confidentially with the SEC in early June 2026. Banks including Goldman Sachs, JPMorgan, and Morgan Stanley are said to be involved. Early investor meetings are already underway. An October window remains possible if market conditions hold.

 

The confidential filing gives the company flexibility. It allows Anthropic to prepare the necessary paperwork and begin conversations with potential public investors without committing to a firm date. Having three of the largest investment banks involved adds credibility and distribution power for any eventual offering.

 

Early meetings also let the company test appetite and refine its story before a formal roadshow. While no listing is certain until it happens, the combination of a completed confidential filing, experienced underwriters, and ongoing investor outreach makes an autumn debut more than theoretical. For current shareholders, this preparation reduces some of the execution risk that can surround large IPOs.

A Still-Supportive AI Spending Environment

Finally, the broader AI spending environment has not yet shown clear signs of exhaustion. Corporations continue to experiment with and adopt frontier models even as they become more cost-conscious. Anthropic’s focus on enterprise rather than pure consumer volume may help it weather any slowdown in lighter usage.

 

Many companies are still in the phase of discovering where AI delivers measurable productivity gains. Even as finance teams scrutinize budgets more closely, demand for tools that clearly improve coding speed, analysis quality, or internal efficiency has remained solid. 

 

Because Anthropic’s revenue mix leans toward these practical enterprise uses rather than high-volume consumer chat, some investors believe the company is better positioned than pure consumer-oriented players if overall spending growth moderates. The absence of an obvious spending cliff so far gives the optimistic case room to breathe.

Putting the Advantages Together

Taken together, these points explain why some existing shareholders are comfortable projecting valuations that more than double the May private mark. Strong product adoption inside businesses, substantial capital resources, concrete steps toward a public listing, and continued corporate interest in frontier models form a coherent set of supporting arguments. 

 

None of them removes the risks that still surround any high-valuation IPO, but they help show why the people already invested remain willing to discuss numbers in the $2 trillion to $3 trillion range.

Optimism is not the whole story. The same investors who talk about $2 trillion also list several concrete worries.

 

Competition from lower-priced models is real. Chinese labs have released capable open-weight systems that undercut Western pricing. If more customers decide that “good enough” is sufficient, Anthropic’s premium positioning could come under pressure.

 

Corporate AI budgets are another soft spot. After two years of rapid experimentation, finance teams are starting to ask harder questions about return on investment. High token prices or heavy infrastructure costs can become sticking points.

 

Regulatory and political friction also matters. Anthropic has had public disagreements with the current U.S. administration over export controls and other policy issues. Ongoing litigation and shifting rules around advanced models create uncertainty that public-market investors dislike.

 

Secondary-market prices have cooled a bit. After the May funding round at $965 billion, implied valuations on platforms tracking private share trades later slipped toward the low $800 billion range, roughly 14 percent below the last official mark. That does not mean the company is in trouble, but it shows that not every buyer is willing to pay the peak private price.

 

Internal culture has also drawn attention. As the company scaled past 2,500 employees, some reports described rising tension around the intensity of its original safety-and-values focus. CEO Dario Amodei has long said he spends a large share of his time protecting that culture through regular all-hands discussions. Growth always tests cohesion; whether the current strain is temporary or structural remains an open question for outsiders.

 

None of these risks automatically kills a high valuation. They do mean the IPO will be a genuine test of whether public markets share the private investors’ confidence.

The next few months will clarify how much of the $2 trillion–$3 trillion talk survives contact with the roadshow. Anthropic’s management has not committed to a number. Revenue will keep rolling in, competitors will keep shipping models, and political winds can shift quickly.

What is already clear is that Anthropic has turned Claude into one of the fastest-growing enterprise software businesses in recent memory. Whether that growth can justify the largest IPO valuation ever attempted is the question public investors will answer this autumn.

 

For anyone watching the AI sector, the episode is a useful reminder: private-market enthusiasm can run far ahead of public-market reality, and the gap between the two is where both the biggest gains and the sharpest corrections tend to appear.

 

If you follow technology markets, keep an eye on the actual S-1 disclosures when they become public and on the quarterly revenue updates that will accompany any listing. Those numbers, more than any investor quote, will decide whether $2 trillion was ambitious or simply the new normal.

When might Anthropic go public?

Investors interviewed in August 2026 pointed to as early as October of that year. The company filed confidentially in June and has been holding early meetings with potential investors. Timing still depends on market conditions.

What is Anthropic’s current private valuation?

The last official funding round in May 2026 valued the company at $965 billion. Secondary-market implied prices have since fluctuated, with some platforms showing figures in the low-to-mid $800 billion range as of mid-August.

How much revenue is Anthropic generating?

In May 2026, the company said its annualized revenue run-rate had exceeded $47 billion. Some investors expect that figure to reach $100 billion to $120 billion by year-end.

Could the IPO really reach $3 trillion?

One investor suggested that a 30x revenue multiple on $100 billion-plus in annualized sales could produce a $3 trillion valuation if growth remains extremely high. That remains a private-investor projection, not a company target.

How does this compare with SpaceX’s IPO?

SpaceX was listed in June 2026 at roughly $1.77 trillion and raised about $75 billion, setting a new record. A $2 trillion debut for Anthropic would surpass it.

What are the main risks to the high valuation?

Investors themselves cite competition from cheaper Chinese models, potential limits on corporate AI spending, regulatory friction with the U.S. government, and the usual challenges of scaling culture and infrastructure at high speed.

Is Anthropic more valuable than OpenAI right now?

In the May 2026 private round, Anthropic’s $965 billion valuation moved ahead of OpenAI’s then-reported figure. Secondary markets have shown similar flips at different points in 2026. Rankings can shift quickly.

Should ordinary investors try to buy Anthropic shares before the IPO?

Pre-IPO shares trade only on private secondary markets restricted to accredited investors and usually require company approval. Most people will have to wait for a public listing if and when it occurs.
