Anthropic has filed plans for an initial public offering that could raise as much as $64 billion and value the artificial intelligence company at up to $1.4 trillion. The proposed listing would make the Claude developer the first major AI model company to enter public markets.
The filing gives investors a detailed look at Anthropic’s rapid revenue growth, enormous computing commitments and warnings about the regulatory and societal risks associated with advanced AI. It also places the company’s public debut at the centre of a wider debate over whether spending on artificial intelligence can continue at its current pace.
Anthropic sets out proposed IPO terms
According to the company’s filing with the US Securities and Exchange Commission, Anthropic plans to offer 825 million shares at between $70 and $78 each. The shares are expected to trade under the ticker “ANT”, although the proposed timetable remains subject to the normal regulatory and market processes.
Seven technology companies, including Google, Nvidia, AMD and Microsoft, have agreed to purchase $26 billion of non-voting shares at the IPO price through a separate private placement. Those companies are either investors in Anthropic or important suppliers of the computing infrastructure needed to train and operate its AI systems.
Anthropic had previously been expected to seek as much as $100 billion, which would have surpassed the largest initial public offerings on record. Even at the top of its stated range, however, the proposed transaction would remain below the $86 billion raised by SpaceX in its June IPO at a reported valuation of $1.77 trillion.
Why the Anthropic IPO matters to AI investors
The planned listing is being watched as a test of investor confidence in the artificial intelligence sector. Anthropic is one of the leading developers of foundation models, and its Claude products compete in a market requiring substantial investment in data centres, specialised chips and electricity.
A public listing would give investors access to a company whose growth has been closely linked to the broader AI infrastructure boom. It would also expose Anthropic to quarterly scrutiny over revenue, cash requirements, profitability and the cost of securing future computing capacity.
Market strategist Art Hogan described the offering as another stage in investor concerns about how the AI buildout is financed. That question has become more prominent as technology shares have experienced periods of volatility and analysts have reassessed the valuations assigned to AI companies.
Key details in the filing
- Company: Anthropic, developer of the Claude AI models
- Proposed offering: Up to $64 billion
- Shares offered: 825 million
- Indicative price range: $70 to $78 per share
- Proposed ticker: ANT
- Potential valuation: Up to $1.4 trillion
- Additional private placement: $26 billion in non-voting shares
Revenue is rising, but so are computing costs
Anthropic reported revenue of $17 billion in the third quarter, compared with $1.4 billion a year earlier, according to the filing. Its annualised run-rate revenue was approximately $81 billion on 31 October, an increase of $10 billion from the end of September.
An annualised run rate is an estimate of what revenue could reach over a full year if current performance continued. It is not the same as confirmed annual revenue, and investors will be watching whether Anthropic can maintain that pace as competition intensifies and customers assess the cost of AI services.
The filing also highlights the company’s unusually large spending obligations. Anthropic has committed hundreds of billions of dollars to computing capacity and warned that it may still have to make many of those payments if demand falls below expectations. That creates a central investment risk: strong demand may support rapid growth, but weaker demand could leave the company carrying substantial fixed costs.
AI safety and regulatory risks disclosed
Anthropic’s filing devotes significant attention to the potential dangers of advanced AI systems. The company says such systems could create catastrophic or existential risks if they are not developed and deployed responsibly.
It also warns that its positions on AI safety and regulation could expose it to political backlash or disproportionate regulatory action. Those disclosures reflect the increasingly contested policy environment surrounding artificial intelligence, particularly where commercial AI tools overlap with national security, defence and public-sector use.
The filing refers to tensions with the administration of President Donald Trump after the Pentagon labelled Anthropic a national security risk. The company had refused to remove restrictions on military use of its technology. The issue illustrates the difficult balance facing AI developers that must serve commercial customers while setting limits on potentially sensitive applications.
Founders to retain voting control
Anthropic’s proposed governance arrangements would leave its seven co-founders with just over half of shareholder voting power after the listing. The group is led by chief executive Dario Amodei and president Daniela Amodei.
Because the founders would retain majority voting control, outside shareholders would not be able to outvote them on company decisions. Such structures can allow a technology company’s leadership to pursue long-term strategies, but they also limit the influence of public investors.
What happens next?
The proposed IPO is not yet a completed transaction. Anthropic must proceed through the US securities-registration and offering process, while the final price, number of shares and trading timetable may change in response to regulatory review and market conditions.
The company has been aiming to list during the week of 16 November, with reports indicating that trading could begin on 19 November. Those dates should be treated as proposed targets until confirmed through official filings or an exchange announcement.
For European investors, policymakers and technology companies, the listing will offer a closely watched public-market reference point for the value of advanced AI businesses. It may also sharpen discussion around AI regulation, computing supply chains, competition and the financial sustainability of the sector.
Conclusion
The Anthropic IPO could become one of the most significant technology listings in years, with a potential valuation of $1.4 trillion and an offering of up to $64 billion. Its filing shows both sides of the AI investment story: exceptional revenue growth alongside enormous infrastructure costs, governance questions and acknowledged safety risks. The next decisive step will be the completion of the regulatory process and confirmation of the final terms before trading begins.
