Isomorphic Labs Closes $2.1B Series B Led by Alphabet and Thrive

Isomorphic Labs, the Google DeepMind drug-discovery spinout, has closed a $2.1 billion Series B co-led by Alphabet and Thrive Capital. The round is the largest non-frontier-lab AI investment of the week, confirming that vertical AI-for-science remains a tier-1 venture category even as horizontal LLM funding concentrates around a small number of frontier labs.

Why It Matters

Capital bifurcation is sharpening: frontier labs attract mega-rounds while vertical AI-for-science captures the largest sectoral investment. Generic horizontal AI-as-a-service plays are conspicuously absent from this week's major deal flow.
