Isomorphic Labs secures $2.1 billion in funding with backing from Alphabet and UK Sovereign AI Fund

LONDON — Isomorphic Labs raised $2.1 billion in a massive funding round, the London-based artificial intelligence drug discovery company and Google DeepMind spin-out said in a statement on Tuesday. The fresh capital pushes the valuation of Isomorphic Labs significantly higher within the competitive technology sector, where Alphabet and other major stakeholders direct substantial resources toward automated pharmaceutical research.

The UK Sovereign AI Fund participated directly in the $2.1 billion investment, according to corporate disclosures released on Tuesday, prompting parliamentary questions regarding the long-term ownership structure of Isomorphic Labs. Lawmakers and regional competitors examined whether the Isomorphic Labs transaction aligns with broader British technological interests or creates foreign dependencies within the London startup sector.

Alphabet, the parent company of Google, retains a substantial equity stake in Isomorphic Labs following the completion of the $2.1 billion transaction, cementing majority control within the Silicon Valley corporate giant. Company executives at Alphabet declined to provide a breakdown of voting rights or board seats allocated to the UK Sovereign AI Fund during the 14-week negotiation period leading up to Tuesday's announcement.

British technology firms received a record volume of venture capital over the last 12 months, but the Isomorphic Labs financing highlights a heavy reliance on external giants like Alphabet and state-backed vehicles investing $2.1 billion at once. Corporate filings in London showed that Isomorphic Labs remains heavily tethered to Google DeepMind infrastructure despite operating as a legally distinct corporate entity since its founding.

Isomorphic Labs did not disclose specific valuation figures, projected commercial timelines, or exact equity percentages for Alphabet and the UK Sovereign AI Fund in the $2.1 billion filing submitted to regulators on Tuesday. A spokesperson for Isomorphic Labs declined to answer questions regarding whether future fundraising rounds will reduce Alphabet below 50 percent ownership before the end of 2026.
