Anthropic Stock & IPO 2026: Valuation, How to Invest Pre-IPO

Anthropic raised $65 billion at a $965 billion valuation in its May 2026 Series H round and confidentially filed its S-1 with the SEC on June 1, 2026. The company is targeting an October Nasdaq listing at a debut valuation expected to exceed $1 trillion, which would make it the first pure AI safety company to go public and one of the largest offerings in stock-market history, according to Fortune.

Can you buy Anthropic stock? (Pre-IPO status)

Anthropic stock is not yet publicly traded. The company is in the pre-IPO phase: it filed its confidential S-1 in June 2026 and began scheduling investor meetings for the roadshow in July 2026, according to Bloomberg. Until the offering closes, retail investors cannot buy Anthropic stock through a standard brokerage.

Accredited investors may be able to access pre-IPO shares through secondary markets including Forge Global, EquityZen, and Hiive. These platforms match buyers with employees or early investors who wish to sell before the IPO. Standard risks of secondary market transactions apply: limited liquidity, uncertain pricing, and potential transfer restrictions. This is a factual description of available access routes; it is not an offer or solicitation.

Anthropic valuation history

Anthropic has grown from a $61.5 billion valuation in early 2025 to nearly $1 trillion in a series of back-to-back funding record rounds. The May 2026 Series H raised $65 billion at a $965 billion post-money valuation, the largest private funding round in history, surpassing OpenAI's own prior record, according to TechCrunch.

The company's run-rate revenue has crossed $47 billion, and the Wall Street Journal has reported that analysts project a 130% revenue surge that would bring Anthropic to its first operating profit. Goldman Sachs, JPMorgan, and Morgan Stanley are leading the offering, which is expected to raise more than $60 billion, per Fortune.

How to buy Anthropic stock

Until the IPO closes, Anthropic shares are accessible only through accredited channels. The primary routes are:

• Forge Global: A regulated marketplace connecting buyers with holders of pre-IPO employee and investor shares. Forge lists Anthropic with active buyer demand; supply depends on willing sellers.
• EquityZen and Hiive: Platforms that aggregate share supply from early investors and employees ahead of an IPO. Both require proof of accredited investor status.
• SPVs: Some venture funds pool capital into special purpose vehicles to invest in late-stage private companies. Fees and lock-up terms vary by fund.
• Public IPO: If the October 2026 Nasdaq listing proceeds, Anthropic shares will become available to all investors through standard brokerage accounts. Watch the company investor relations page for final pricing and timing.
