About Anthropic
Anthropic is an artificial intelligence (A.I.) safety and research company formed by siblings and former OpenAI employees Daniela Amodei and Dario Amodei. The duo left their previous employer due to directional differences in agreement with leadership.
The company aims to build “reliable, interpretable, and steerable A.I. systems,” putting A.I. safety at the forefront of its research.
Its large language model (LLM), Claude, is a competitor to OpenAI’s ChatGPT, Elon Musk’s xAI, and the French startup Mistral AI.
Claude abides by “Constitutional A.I” for oversight and transparency. It uses sources such as the United Nations Universal Declaration of Human Rights to help the tool self-select ethical and harmless responses.
Microsoft invested a significant sum into OpenAI in late January 2023, prompting Google to complete a sizable investment ($300 million/10% stake) in Anthropic just over a week later. The deal included an agreement to use the Google Cloud platform. Anthropic also partners with Scale for generative A.I. applications.
The tech behemoth divergence sets up a long-term rivalry for dominance in A.I. LLMs.
Anthropic is based in San Francisco.
Here’s a recent podcast episode about a potential Anthropic IPO in 2026 or 2027:

Key Anthropic Funding Rounds (2021-2025)

Valuation
The latest confirmed Anthropic valuation is $183 billion based on a Series F funding round that raised $13 billion in September 2025.
However, a November 2025 report revealed the company is raising new money at a $300+ billion valuation.
Secondary marketplace transaction data from Caplight and Hiive indicate the valuation is around $320 billion as of Q4 2025.
IPO Potential
The Anthropic IPO date is currently unknown. But a December 2nd, 2025, report from the Financial Times indicated the company has hired lawyers to lead the deal, and is talking to investment banks.
Internally, it is reported that the company is working through a checklist to prepare for its public debut.
The FT report cited sources who said the Anthropic IPO date could be as early as 2026. However, another source indicated a 2027 IPO is more likely.
Considering the size and complexity of the deal, this analyst thinks a 2027 IPO is more likely.
Anthropic leadership is now pursuing an IPO due to its size and capital needs. An acquisition seems like an unlikely outcome, as does staying private for much longer.
However, if the private AI valuations hit turmoil, one of the Mag 7 companies could allocate capital for an acquisition.
As a public benefit corporation, Anthropic may decide to pursue an IPO to allow retail investors and institutions to join in their mission to harness A.I. to improve humanity in a safe and controlled manner.
Watch for reporting about exploring a possible IPO with investment banks or filing a confidential S-1 filing with the SEC.

How to Invest in Anthropic Stock
Anthropic has become increasingly available to accredited and non-accredited investors on pre-IPO investing platforms. Below you’ll find easy access to Anthropic equity for low or high-dollar investors.
1. Access Anthropic stock via venture capital funds
Anthropic stock is a holding in multiple prominent pre-IPO venture capital funds. Non-accredited investors are welcome to invest.
All U.S-based retail investors 18+ can own these funds to gain investment exposure to Anthropic stock. There’s a $10 minimum investment.
Read more about venture capital funds here.
2. Invest via pre-IPO marketplaces
Accredited investors can monitor pre-IPO platforms, including Hiive, EquityZen, Augment, and Forge Global, for availability.
Perform due diligence before investing, and consider the available valuations against multiple marketplaces for an accurate valuation. Beware of high fees and inflated valuations in secondary markets.
Shares may be offered for sale by early investors or employees before the IPO, especially if the company raises more venture capital.
Minimum investments range from $10,000 to $50,000 or more on these platforms.
Signing up for online access to pre-IPO data, deal alerts, and expressing interest in currently unavailable startups is free.
Check out our list of top pre-IPO investing platforms for current share availability across platforms.
3. Participate in the Anthropic IPO through a broker
Anthropic has conducted multiple private funding rounds over its lifecycle.
Several venture capital firms, corporate venture arms, and individual investors have invested in Anthropic. Though liquidity in the private markets is available, the company’s size will eventually require it to IPO .
IPO access is currently trending in favor of retail investors. We’re seeing more access to IPO shares, so it’s become more possible to invest in the larger deals.
Due to its massive scale, Anthropic IPO shares will likely be available to retail investors.
The following online brokers give customers free access to IPOs, even with low account balances:
Exclusive access to highly sought-after IPOs may be limited based on the type of brokerage accounts you hold and which brokerages have secured exclusive rights.
TradeStation has a longer track record of accessing IPOs and secondary offerings via its partnership with Click Markets.
But Robinhood has the advantage of Silicon Valley networks and a history of getting allocations for high-profile IPOs.
Read the S-1 filings to find mentions of these online brokers to find opportunities.
Check out this list of best brokers for IPO investing to learn more about IPO access for retail investors.
4. Invest indirectly
Alphabet (Google) invested $300 million into Anthropic in February 2023. In October 2023, it committed to an additional $2 billion investment, $500 million up front and another $1.5 billion over time.
Individual investors who own Google stock now own a small portion of Anthropic, albeit a very small amount.
Not to be outdone, Amazon has invested $4 billion in Anthropic. Own either company to indirectly own Anthropic stock.
Other public companies that own a portion of Anthropic include Salesforce, Microsoft, NVIDIA, SAP, and Zoom. However, the ownership percentage of each company is unclear.
5. Buy the stock after the IPO
Most investors will not acquire pre-IPO shares or receive an allocation during the IPO.
Waiting for startups to become publicly traded companies can have advantages. The IPO filing provides investors with access to financial data, and each subsequent quarter paints a more complete picture.
IPO stock prices typically rise with high-demand companies. You can benefit if you’re in early and sell when the price overheats.
Without IPO access, post-IPO investors may be tempted to acquire shares at inflated prices.
Avoid chasing over-inflated share prices right after the IPO. Stock price declines after IPOs can be excellent entry points.
Be selective and patient. The most disruptive companies are likely to experience higher valuations a decade from now.
Investor Takeaways
Anthropic’s path toward a public listing reflects both its explosive growth and the rising expectations placed on companies shaping the future of artificial intelligence.
The firm’s valuation momentum and rapid institutional backing indicate confidence not just in its technology, but in its governance-first approach (similar to Safe Superintelligence) to model development.
Investors evaluating Anthropic’s IPO potential should weigh the company’s unusual public-benefit structure, which may influence how leadership balances commercialization with safety commitments.
The active secondary-market activity underscores strong demand, yet also signals that pricing discipline will matter as private valuations continue to stretch. For individuals seeking early exposure, the expanding pre-IPO access points are a broader democratization of private-market investing, but due diligence remains essential given fast-moving valuations.
If Anthropic proceeds with an S-1, the disclosures will offer the clearest window yet into the sustainability of its revenue model and competitive position against OpenAI, Google, and other LLM rivals. For now, watching the company’s legal, banking, and funding updates provides the best insight into how close it truly is to stepping onto public markets.
Investors considering an investment in the Anthropic IPO should carefully consider the risks and read the SEC filings.
