Anthropic Valuation Hits $965B, Surpassing OpenAI with $65B Series H
On May 28, 2026, Anthropic announced the completion of its Series H funding round, securing $65 billion at a $965 billion post-money valuation. This figure means Anthropic has officially surpassed OpenAI to become the world’s highest-valued AI company.
Funding Structure and Key Metrics
| Item | Data |
|---|---|
| Funding Round | Series H |
| Amount Raised | $65 billion |
| Post-Money Valuation | $965 billion |
| Lead Investors | Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital |
| Annualized Revenue | Over $47 billion (as of May 2026) |
| Revenue Three Years Ago | ~$1.4 billion (annualized) |
Revenue growth is the core driver of this valuation. Over the past three years, Anthropic’s annualized revenue has grown more than 10x each year. From $1.4B to $47B, that curve is more convincing than any pitch deck.
The Significance of Surpassing OpenAI
OpenAI completed its latest funding round on March 31, 2026, at an $852 billion post-money valuation. Anthropic overtook it just two months later.
This is not a coincidence.
- Anthropic’s focus on coding: Since the launch of Claude Code, annualized revenue has reached $1 billion, and the AI agent product Cowork further expands use cases
- Faster revenue growth: While OpenAI’s revenue growth is strong, Anthropic’s multiples are higher
- Chip giant backing: Micron, Samsung, and SK Hynix participated, creating vertical supply-chain alignment
Claude Opus 4.8 Launched the Same Day
On the day of the funding announcement, Anthropic simultaneously released Claude Opus 4.8. Key upgrades include:
- Comprehensive benchmark improvements: All test scores improved over Opus 4.7
- Speed mode: 2.5x faster execution at one-third the cost of the previous generation
- Dynamic workflows: New capability in Claude Code for handling ultra-large-scale complex problems
- Effort control: Users can manually adjust how much compute Claude dedicates to a single task
More importantly, pricing remains unchanged. Against the backdrop of rising compute costs, this is a direct competitive advantage.
The Reality of Compute Scarcity
Anthropic also faces an industry-wide problem: AI compute shortage. Surging demand sometimes forces the model to “dumb down” to conserve resources. A significant portion of the $65B raised will go toward compute expansion.
This explains why chip giants participated. This is not purely financial investment; it is supply-chain binding.
Industry Impact
- Valuation ceiling shattered: $965B sets a new benchmark for subsequent AI company fundraising
- Coding AI becomes the main battleground: Anthropic’s path proves that vertical use cases deliver more commercial value than general chat
- Compute becomes the bottleneck: Where the raised capital goes will reveal the true cost structure of AI companies
- Competitive landscape solidifies: The gap between the top two (Anthropic/OpenAI) and other players widens further
