Anthropic’s valuation has reportedly surged past $600 billion in the secondary (unlisted) market, according to the latest trades on private exchanges like Forge Global and Hiive. This unlisted rally follows a monumental $30 billion Series G round in February that officially pegged the company at $380 billion.
The massive “secondary premium” reflects intense investor FOMO (Fear Of Missing Out) ahead of a rumored October 2026 IPO, which some analysts believe could target a public valuation of nearly $1 trillion.
1. The Secondary Market Surge
While Anthropic’s last “official” primary valuation was $380 billion, the private market is currently pricing shares at a significant markup.
- Implied Valuation: Recent blocks of employee and early-investor shares have traded at prices implying a $600B+ total valuation.
- Demand-to-Supply Ratio: For every share available for sale in the secondary market, there are currently an estimated 14 active bids, one of the highest liquidity ratios in private tech history.
- The “OpenAI Halo”: The rally is partially driven by OpenAI’s recent $852 billion valuation; investors are betting that Anthropic, with its superior enterprise revenue mix, should trade at a similar or even higher multiple.
2. Financial Fundamentals (FY26)
Anthropic’s valuation isn’t just hype; it is supported by the fastest revenue growth ever seen in the software sector.
| Metric | Performance Status |
| Annualized Revenue Run-Rate | $14 Billion (as of Feb 2026) |
| Revenue Growth | 7x to 10x Year-on-Year |
| Claude Code Revenue | $2.5 Billion (The fastest-growing product in company history) |
| Enterprise Mix | 80% of revenue comes from Fortune 500 business customers. |
3. The “October 2026” IPO Roadmap
Anthropic has reportedly engaged the law firm Wilson Sonsini and added former Microsoft CFO Chris Liddell to its board, signals that usually precede a public listing.
- Target Raise: The company is reportedly looking to raise $60 billion in its IPO, which would make it one of the largest public debuts in history.
- Strategic War Chest: The IPO proceeds are intended to fund a $50 billion infrastructure expansion, including a massive proprietary data center cluster to compete with OpenAI’s “Stargate.”
- Market Significance: Analysts at GO Markets suggest that an Anthropic IPO would be a “defining moment,” potentially resetting the valuation of the entire software-as-a-service (SaaS) industry.
4. Competitive Context: Anthropic vs. The World
Anthropic’s $600B+ unlisted valuation now makes it more valuable than the combined market capitalization of India’s top five IT firms (TCS, Infosys, HCLTech, Wipro, and Tech Mahindra).
- The Disruption Factor: Investors are moving capital away from traditional IT services and into Anthropic because tools like Claude Code are now authoring an estimated 4% of all public GitHub commits globally.
- The “Safe” Alternative: Anthropic’s “Constitutional AI” branding continues to win over enterprise clients who are wary of the more “consumer-first” or “unpredictable” nature of rivals.
5. Risk Factors for Investors
Despite the euphoria, secondary market experts warn of several “red flags”:
- Concentration Risk: Anthropic is heavily dependent on the continued “compute supply” from partners like Amazon and Google.
- Profitability Gap: While revenue is $14B, the company is still burning over $5 billion annually due to infrastructure and R&D costs.
- Regulatory Scrutiny: Increased attention on “Sovereign AI” and export restrictions could impact Anthropic’s ability to sell its most advanced models in key global markets.
