GIC and Temasek anchor Singapore's stake in Anthropic's $65bn Series H at $965bn valuation

Singapore's two sovereign investors, GIC and Temasek, anchored Singapore's participation in a landmark $65 billion Series H round for AI developer Anthropic that values the company at $965 billion post-money — one of the largest private financings ever and a defining sovereign-wealth-fund move of the window. Per Anthropic's announcement (dated May 28, 2026; the GIC/Temasek SWF angle was reported May 29-June 1, within the window), the round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. GIC participated as a co-lead investor alongside Capital Group, Coatue, D1 Capital Partners, ICONIQ and XN; Temasek was named among the broader significant-investor group, which also included Blackstone, Brookfield, Fidelity, T.

Rowe Price, Baillie Gifford, Lightspeed, General Catalyst, MGX and Jane Street. Critically, the $65 billion figure is not all-new cash: Anthropic states the round 'also includes $15 billion of previously committed investments from hyperscalers,' among them $5 billion from Amazon, Anthropic's primary cloud/training partner — so the $15 billion sits INSIDE the $65 billion total, not on top of it. The raise followed Anthropic's disclosure that annualized run-rate revenue had crossed $47 billion, and a string of compute deals (Amazon up to 5GW; Google/Broadcom 5GW of next-gen TPUs).

For the COFFERS desk, the significance is the deepening tilt of state-owned capital — Gulf and Singapore funds in particular — into frontier-AI equity at near-trillion-dollar valuations, concentrating sovereign balance sheets in a single, fast-moving technology bet and reshaping global allocation of patient capital.
