What is Anthropic's new $30 billion funding round?
AI company Anthropic is closing a record-breaking funding round exceeding $30 billion, according to Bloomberg sources, pushing its valuation above $900 billion. This makes Anthropic the most valuable private AI startup in the world, surpassing rival OpenAI's $852 billion valuation from March 2026. The news, reported on May 23, 2026, comes just months after Anthropic closed a separate $30 billion round in February 2026 at a $380 billion valuation, illustrating the staggering pace of growth in the AI sector.
How does this compare to OpenAI?
Anthropic's new valuation of over $900 billion eclipses OpenAI's $852 billion valuation from its March 2026 funding round. OpenAI raised $40 billion in that round, led by SoftBank. However, Anthropic's rapid ascent — from $61.5 billion in March 2025 to over $900 billion in May 2026 — represents roughly a 15-fold increase in just 14 months. Both companies are now preparing for initial public offerings (IPOs), with OpenAI filing confidentially on May 22, 2026, and Anthropic expected to pursue a listing as early as October 2026. The AI startup IPO race is intensifying as these two giants compete for public market dominance.
Key details of the funding round
Investors and terms
The new round is co-led by Sequoia Capital, Dragoneer, Altimeter Capital, and Greenoaks Capital, according to insiders. Amazon and Google have also committed substantial additional investments. This follows Anthropic's February 2026 Series G round of $30 billion at a $380 billion valuation, which was co-led by GIC and Coatue, with participation from Microsoft, Nvidia, D.E. Shaw Ventures, Founders Fund, ICONIQ, and MGX. The largest private tech funding rounds in history now include both Anthropic and OpenAI at the top.
Revenue and growth metrics
Anthropic reports $14 billion in annualized run-rate revenue as of February 2026, growing over 10x annually for three years. The company projects $10.9 billion in Q2 2026 revenue alone. Claude Code, its agentic AI coding tool, has reached $2.5 billion in annualized revenue, with an estimated 4% of all GitHub public commits now authored by Claude Code. Over 500 customers spend more than $1 million annually with Anthropic, and eight of the Fortune 10 use Claude.
Why is Anthropic raising so much capital?
The massive funding rounds are driven by the enormous capital requirements of frontier AI development. Anthropic is investing heavily in:
- Infrastructure expansion: The company recently signed a $1.8 billion cloud computing deal with Akamai Technologies and a deal with xAI for access to its Colossus 1 data center.
- Research and development: Anthropic launched Opus 4.6, its newest frontier model, and introduced over 30 products and features in January 2026 alone.
- AI safety: The company maintains its focus on building reliable, interpretable, and steerable AI systems, a key differentiator from competitors.
- Enterprise growth: Claude's enterprise adoption has surged, with the assistant now used by eight of the ten largest Fortune companies.
IPO plans and market implications
Anthropic is expected to pursue an IPO in New York as early as October 2026, directly competing with OpenAI's targeted Q4 listing. The Anthropic IPO timeline will be closely watched by investors seeking exposure to the AI boom. However, the company faces legal risks, including a $1.5 billion copyright settlement and a separate $3 billion music copyright lawsuit, which could impact its public debut.
What does this mean for the AI industry?
Anthropic's meteoric rise signals an unprecedented concentration of capital in frontier AI. The company's valuation growth from $61.5 billion (March 2025) to $380 billion (February 2026) to over $900 billion (May 2026) reflects investor conviction that AI will reshape the global economy. Dario Amodei, Anthropic's CEO and co-founder, has stated that the company's mission is to build AI systems that are "reliable, interpretable, and steerable" — a safety-first approach that has resonated with enterprise customers and investors alike.
