Anthropic announced on May 28, 2026, that it had closed a $65 billion Series H funding round, pushing its post-money valuation to $965 billion and making it the most valuable private AI company in the world. The round puts Anthropic above OpenAI’s last reported valuation of approximately $852 billion.
The round was led by Altimeter Capital, Dragoneer Investment Group, Greenoaks Capital, and Sequoia Capital. Beyond the financial backing from those growth investors, the round introduced three strategic partners from the semiconductor and memory hardware space: Micron Technology, Samsung, and SK hynix. Their involvement signals something beyond a bet on AI software. These are the companies that manufacture the memory chips and storage systems that large AI models depend on at training and inference scale. Their investment in Anthropic ties infrastructure supply directly to a specific model ecosystem.
Anthropic was founded in 2021 by former OpenAI researchers, including CEO Dario Amodei and President Daniela Amodei. At $965 billion, the company sits just below the $1 trillion threshold that would place it alongside Apple, Microsoft, Nvidia, and Alphabet. For context, Anthropic’s first major fundraise valued it at under $1 billion. The current figure reflects how dramatically enterprise AI spending has accelerated in less than four years.
The round follows a broader shift in how the AI market is being valued: less on user numbers and more on enterprise revenue, API consumption, and infrastructure relationships. The addition of Micron, Samsung, and SK hynix as strategic investors reinforces that the next competitive frontier in AI is not model capability alone. It is access to compute and memory at scale.
For companies that have built their AI stack on Claude, this round has practical implications. First, Anthropic will have capital to continue model development and infrastructure investment without pressure to monetize aggressively in the near term. Second, the chip maker partnerships suggest a potential path toward more predictable hardware access, which has been a constraint on both training new models and scaling inference for large customers.

For businesses operating in Latin America and other emerging markets, the valuation underscores that Claude is enterprise infrastructure backed by institutional capital at a scale comparable to the largest public tech companies. That stability matters for teams evaluating long-term AI vendor risk.
The question of whether Anthropic can sustain a near-$1 trillion valuation as a private company will depend on its ability to convert the current momentum in enterprise AI adoption into durable, high-margin revenue. With OpenAI and Google as its primary competitors for enterprise contracts, the next 12 to 18 months will test whether the valuation reflects fundamentals or the current appetite for AI bets at any price.
