Singapore’s investment in Anthropic’s $65 Bn Series H financing anchored by GIC and Temasek

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

Temasek joined as a major investor, and GIC joined Capital Group, Coatue, D1 Capital Partners, ICONIQ, and XN as co-lead investors in the round, according to a statement released on Friday. Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital led the round.

The fundraiser coincides with Anthropic’s announcement earlier last month that its annualized run-rate revenue exceeded $47 billion, demonstrating the quick uptake of Claude among business clients worldwide. A Series G in February 2026 was the company’s most recent significant funding round.

According to Anthropic, the money will be used to grow computational infrastructure, scale its partnerships and products, and support safety and interpretability research. Amazon, which continues to be Anthropic’s principal cloud and training partner, contributed $5 billion of the $15 billion in hyperscalers’ already pledged investments.

Anthropic has acquired significant computing agreements in recent weeks to meet the increasing demand, including one with SpaceX for GPU access across its Colossus 1 and 2 facilities, one with Amazon for up to five GW of capacity, and another with Google and Broadcom for five GW of next-generation TPU capacity. All three of the biggest cloud platforms in the world—AWS, Google Cloud, and Microsoft Azure—now provide Claude.

In keeping with Anthropic’s desire to establish dependable supply chains for memory, storage, and logic chips as it grows, semiconductor companies Micron, Samsung, and SK Hynix all joined the round as key infrastructure partners.

The valuation of almost $1 trillion places Anthropic is one of the most valuable private companies ever, demonstrating the speed at which frontier AI has transitioned from research curiosity to essential enterprise infrastructure and the importance of Singapore’s sovereign money in supporting that transition.
