Anthropic’s valuation history is one of the most dramatic stories in modern technology: the maker of Claude has gone from a $124 million Series A round in 2021 to a $965 billion private valuation in May 2026, and is now preparing for one of the largest U.S. IPOs ever. Its proposed Nasdaq listing under the ticker ANT could value the company at roughly $1.02 trillion, depending on where shares price within the announced range.anthropic+1
Anthropic was founded in 2021 by former OpenAI researchers, including siblings Dario Amodei and Daniela Amodei. Dario Amodei remains Anthropic’s co-founder and chief executive officer, leading the company’s research direction and strategy as it positions itself around reliable, interpretable, and steerable AI systems.anthropic+1
Why Anthropic’s Valuation Matters
Anthropic’s rise matters because it is not merely another startup fundraising story. The company is one of the leading developers of frontier AI models and competes directly with OpenAI, Google, Meta, and other major AI labs for enterprise customers, cloud partnerships, talent, and computing capacity.nbcnews+1
Its valuation also reflects a broader shift in U.S. capital markets: investors are assigning enormous value to companies that control advanced AI models, data infrastructure, and enterprise distribution. But Anthropic’s IPO is also a test of whether Wall Street will support trillion-dollar valuations for AI companies whose long-term profitability, capital needs, and competitive position remain uncertain.bloomberg+1

The most striking part of Anthropic’s valuation history is the speed of the final stage. In roughly 14 months, its disclosed post-money valuation rose from $61.5 billion in March 2025 to $965 billion in May 2026—an increase of more than 15 times.rmb.reuters+1
Early Funding: 2021 to 2023
Anthropic began as an AI-safety-focused research company. Its $124 million Series A was announced in May 2021 and was led by investor Jaan Tallinn, with participation from figures including Dustin Moskovitz and Eric Schmidt.anthropic
In April 2022, Anthropic raised $580 million in Series B funding, led by then-FTX CEO Sam Bankman-Fried. The company said the capital would support large-scale experimental infrastructure and research into the safety properties of computationally intensive AI systems.anthropic
By May 2023, Anthropic had raised $450 million in Series C funding led by Spark Capital, with participation from Google, Salesforce Ventures, Sound Ventures, and Zoom Ventures. That round came as Anthropic began expanding Claude and its commercial AI products.anthropic
The 2025 Breakout
Anthropic’s valuation began compounding rapidly in 2025. In March, it raised $3.5 billion at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners.rmb.reuters
Six months later, in September 2025, Anthropic announced a $13 billion Series F round at a $183 billion post-money valuation, led by ICONIQ. The company also said its annualized run-rate revenue had surpassed $5 billion by August 2025, underscoring why investors were willing to pay increasingly high prices for its equity.anthropic
That growth reflected rising demand for Claude among businesses seeking AI assistants, coding tools, document analysis, and enterprise-grade AI deployment. But it also reflected the broader AI investment cycle, in which leading model developers attracted unprecedented amounts of private capital.anthropic+1
2026: From $380 Billion to $965 Billion
In February 2026, Anthropic raised $30 billion in Series G funding led by GIC and Coatue, lifting its post-money valuation to $380 billion.anthropic
Only three months later, in May 2026, the company raised $65 billion in Series H funding led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. That round valued Anthropic at $965 billion post-money, making it one of the most valuable private companies in the world.anthropic
Anthropic said the Series H capital would support safety and interpretability research, expand computing capacity for Claude, and scale products and partnerships. The round also demonstrated how quickly capital had concentrated around a small group of frontier AI companies.anthropic
What the IPO Valuation Means
Anthropic launched its IPO roadshow on November 10, 2026. It is proposing to sell 825 million Class A shares, including 801,351,354 shares from Anthropic and 23,648,646 shares from certain existing stockholders. The company will not receive proceeds from shares sold by selling stockholders.anthropic
The announced IPO price range is $70 to $78 per share. At the top of that range, the offering implies a valuation of about $1.02 trillion, according to reporting based on Anthropic’s filing.anthropic+1
| IPO detail | Current status |
|---|---|
| Ticker | ANT anthropic |
| Exchange | Nasdaq Global Select Market anthropic |
| Proposed price range | $70 to $78 per share anthropic |
| Shares in proposed offering | 825 million Class A shares anthropic |
| Base offering proceeds | Up to $64.4 billion nbcnews+1 |
| Implied valuation at top of range | About $1.02 trillion nbcnews |
| Confirmed trading date | Not yet confirmed anthropic |
Anthropic has also applied to list on Nasdaq under the symbol ANT. Its registration statement has been filed with the U.S. Securities and Exchange Commission, but it had not become effective as of the roadshow announcement, meaning the IPO remains subject to completion of the offering process.anthropic+1
When Is Anthropic Going to IPO?
Anthropic has not confirmed an official first day of trading. The company launched its roadshow on November 10, 2026, and reports indicate it is targeting a Nasdaq debut around November 19 or 20, before the U.S. Thanksgiving holiday. Those dates remain expectations rather than confirmed company announcements.news.bloomberglaw+1
Before shares can begin trading, Anthropic and its underwriters must complete the investor roadshow, set a final IPO price, and complete the offering process. The company’s own announcement says the proposed offering will be made only through a prospectus, and its registration statement had not yet become effective.anthropic
For U.S. investors, the practical takeaway is straightforward: Anthropic could begin trading as soon as mid-to-late November 2026, but no date is guaranteed. Market conditions, investor demand, pricing discussions, and regulatory completion can all affect the final timetable.anthropic+1
Dario Amodei’s Role
Dario Amodei is Anthropic’s co-founder and CEO. He leads the company’s research direction and strategic vision, with a focus on building AI systems that are reliable, interpretable, and steerable.anthropic
Amodei co-founded Anthropic with Daniela Amodei, who serves as president, after both previously worked at OpenAI. Anthropic was created around concerns about AI governance and safety, and it operates as a public benefit corporation—a structure that requires management to balance financial objectives with broader public interests.nbcnews+1
Amodei’s leadership will be closely watched after the IPO because Anthropic’s valuation depends not only on Claude adoption but also on its ability to manage AI safety, regulatory scrutiny, infrastructure costs, and competition from OpenAI, Google, and other major AI developers.nbcnews+1
What Could Change the Valuation
A trillion-dollar IPO valuation is not guaranteed. The final valuation will depend on the ultimate IPO price, the number of shares sold, overall demand from institutional investors, and market conditions during the offering.anthropic+1
Several factors could pressure Anthropic’s valuation:
- AI market volatility: Recent selloffs in AI-related stocks have made investors more cautious about high valuations across the sector.biz.heraldcorp+1
- Capital intensity: Frontier AI development requires enormous spending on computing power, data centers, chips, and research.
- Competition: Anthropic faces intense competition from OpenAI and other AI companies for customers, talent, and market share.nbcnews
- Profitability questions: Investors will scrutinize whether Anthropic can convert rapid revenue growth into durable profits after heavy infrastructure spending.
- IPO pricing: A price below the proposed $70-to-$78 range would reduce the implied valuation; a strong oversubscribed offering could support pricing at or above the range.anthropic
What U.S. Investors Should Watch
For investors considering Anthropic stock, the most important near-term milestone is the final pricing of the IPO. The announced range provides a reference point, but it is not a guaranteed valuation or a promise of where shares will trade after the debut.anthropic
Investors should also watch Anthropic’s prospectus for details on revenue growth, cash burn, compute commitments, customer concentration, governance structure, and dilution. Those disclosures will help determine whether the market views Anthropic as a durable software-and-infrastructure business or as a highly capitalized AI research company still proving its economics.anthropic+1
Anthropic’s journey from a $124 million Series A to a potential trillion-dollar public company is extraordinary, but its next valuation will be decided not by private-market enthusiasm—it will be decided by public-market investors.anthropic+1
