Singapore’s two sovereign wealth funds, GIC and Temasek, have joined a landmark $65 billion Series H funding round for Anthropic, the AI safety company behind the Claude family of models, valuing the firm at $965 billion post-money.

In a statement on Friday, GIC said it participated as a co-lead investor in the round, alongside Capital Group, Coatue, D1 Capital Partners, ICONIQ, and XN. Temasek joined as a significant investor. The round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital.

The fundraise comes as Anthropic reported its annualized run-rate revenue crossed $47 billion earlier this month, reflecting rapid adoption of Claude across enterprise customers globally. The company’s last major raise was a Series G in February 2026.

Anthropic said the funds will be support safety and interpretability research, expanding compute infrastructure, and scaling its products and partnerships. The round includes $15 billion in previously committed investments from hyperscalers, among them $5 billion from Amazon, which remains Anthropic’s primary cloud and training partner.

To support surging demand, Anthropic has secured major compute agreements in recent weeks, such as one with Amazon for up to five GW of capacity, another with Google and Broadcom for five GW of next-generation TPU capacity, and one with SpaceX for GPU access across its Colossus 1 and 2 facilities. Claude is now available on all three of the world’s largest cloud platforms: AWS, Google Cloud, and Microsoft Azure.

Semiconductor firms Micron, Samsung, and SK hynix also joined the round as strategic infrastructure partners, reflecting Anthropic’s need to secure reliable supply chains for memory, storage, and logic chips as it scales.

The near-trillion-dollar valuation places Anthropic among the most valuable private companies ever, underlining how quickly frontier AI has moved from research curiosity to critical enterprise infrastructure — and how central Singapore’s sovereign capital has become to backing that shift.
