If you needed proof that the financial world is moving at breakneck speed, this week delivered it in spades.

We are witnessing an era where “big” numbers are constantly being redefined, driven by an aggressive deployment of strategic capital.

This week’s highlights capture that exact momentum: Singapore’s sovereign wealth funds, GIC and Temasek, just backed a historic, record-breaking fundraise for AI giant Anthropic, while Warren Buffett’s Berkshire Hathaway (NYSE: BRK.B) poured an additional US$10 billion into Alphabet (NASDAQ: GOOGL).

Closer to home, Keppel Ltd (SGX: BN4) massively boosted its power capacity with a future-ready plant, and CapitaLand Ascott Trust (SGX: HMN) unlocked premium value by divesting a prime local hotel.

Anthropic’s record US$65 billion raise

AI safety company Anthropic, the developer behind the Claude family of models, raised US$65 billion in Series H funding on 28 May 2026, valuing the firm at US$965 billion post-money.

The round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, with Singapore’s two sovereign wealth funds prominently involved – GIC co-led the round, while Temasek Holdings joined as a significant investor.

The raise comes just over three months after February 2026’s Series G, which valued Anthropic at US$380 billion.

The company’s annualised run-rate revenue crossed US$47 billion earlier in May, up sharply as enterprise adoption of Claude accelerated.

The financing includes US$15 billion of previously committed hyperscaler investments, among them US$5 billion from Amazon (NASDAQ: AMZN).

Proceeds will fund safety research, compute expansion, and product scaling.

Keppel boosts power capacity by 45%

Keppel Ltd saw its power-generating capacity jump 45% after the Keppel Sakra Cogen Plant, Singapore’s first hydrogen-compatible combined cycle power plant, began commercial operations on 29 May 2026.

The plant is 70% owned by Keppel Asia Infrastructure Fund and 30% owned by Keppel directly.

With a capacity of 600 MW, the facility currently runs on natural gas but can be modified to run entirely on low-carbon hydrogen as supply chains mature.

Notably, its full 600 MW capacity has already been contracted for this year and next, supporting recurring income for the group.

Together with the Keppel Merlimau Cogen Plant, Keppel will now command up to 1,900 MW of power capacity.

Keppel shares closed at S$10.72 on 28 May 2026, down 1.11% for the day but up 4.28% year-to-date.

CapitaLand Ascott Trust divests Robertson House

CapitaLand Ascott Trust, or CLAS, announced on 29 May 2026 that it will divest The Robertson House by The Crest Collection in Singapore for S$360.0 million.
