Anthropic Stock in 2026: $380 Billion Valuation, Record Funding, and an IPO on the Horizon
Anthropic, the AI safety company behind the Claude family of large language models, does not yet have a publicly traded stock. There is no ticker symbol, no share price on any exchange, and no direct purchase pathway for retail investors today. What exists instead is one of the fastest-rising private valuations in technology history — and a credible IPO process already underway.
Anthropic's $380 Billion Valuation and Record Series G Funding Round
In February 2026, Anthropic raised $30 billion at a $380 billion valuation, more than doubling its valuation in just five months. Initially seeking $10 billion, the round was six times oversubscribed, prompting the company to triple the size of the raise.
Nvidia invested $10 billion and Microsoft invested $5 billion in the round, joining existing investors Google and Amazon on the cap table. Eight out of the Fortune 10 companies now count themselves as Anthropic enterprise customers.
The revenue trajectory underpinning this valuation is striking. Anthropic's annualized revenue reached $14 billion by the time the Series G closed, up from just $1 billion at the start of 2025. The company expects sales to reach $40 billion by 2028, with a bull-case estimate of $70 billion.
Anthropic IPO Timeline — What Is Actually Known
In December 2025, Anthropic hired law firm Wilson Sonsini to begin IPO preparations, and the company later clarified that discussions remained informal with no final decisions made. No S-1 registration has been filed with the SEC as of March 1, 2026.
Betting platform Kalshi places Anthropic at a 72% probability of going public before OpenAI. Some insiders have told the Financial Times that a 2027 timeline is more realistic given the complexity of preparing a company of this size for public markets.
Anthropic is one of three historic IPOs potentially arriving in the same cycle, alongside OpenAI and SpaceX, representing a combined estimated market cap of approximately $2.9 trillion — an unprecedented volume for public markets to absorb in a single period.
How to Buy Anthropic Stock Today — Options for Different Investors
Secondary marketplace Hiive shows an estimated Anthropic share price of $417.38 as of February 28, 2026, with 88 live orders active on the platform. Access on secondary markets is restricted to accredited investors and requires Anthropic's approval of any share transfer, making it illiquid and high-risk compared to public market investing.
For retail investors seeking indirect exposure, several publicly traded companies hold meaningful Anthropic stakes. Google holds approximately 10 to 14% of Anthropic, Amazon has invested up to $8 billion, Microsoft committed $5 billion in November 2025, and Nvidia has committed $10 billion.
Zoom made an early investment of $51 million in Anthropic in 2023. Wall Street analysts now estimate that stake could be worth $2 billion to $4 billion, potentially representing close to 20% of Zoom's current market cap — a figure not yet reflected on the balance sheet.
The KraneShares AGIX ETF is currently the only publicly listed ETF with direct ownership exposure to Anthropic. The firm established its Anthropic position in early 2025, and by year-end the position had appreciated to an estimated fair value approximately four times its initial cost. The Fundrise Innovation Fund also holds an Anthropic stake with a minimum investment of $10, accessible to non-accredited investors.
Key Risks Every Investor Should Understand
Anthropic stock remains entirely pre-IPO. The safest and simplest approach for most retail investors remains waiting for the Anthropic IPO, which could arrive as early as late 2026 but may not come until 2027.
The latest valuation of $380 billion implies a price-to-sales ratio of approximately 78, making Anthropic more expensive than OpenAI on a revenue multiple basis. Regulatory uncertainty, competitive pressure from OpenAI and Google DeepMind, and the sheer structural complexity of a potential listing at this scale are material risks any prospective investor must weigh carefully. Anthropic anticipates positive free cash flow in 2027 and its first profitable year in 2028.
