Anthropic launches Claude Science and moves into drug discovery

The company behind Claude now wants to make medicine.

On June 30, 2026, Anthropic launched Claude Science, a research product for drug discovery built the way Claude Code is built for software. Alongside the product, the company announced its own programs to develop treatments for rare and neglected diseases.

A serious bet, not a side project

The moves around the launch signal how seriously Anthropic is taking this. The company hired John Jumper, the Nobel-winning DeepMind scientist behind AlphaFold, who left Google DeepMind to join Anthropic. It acquired AI biotech startup Coefficient Bio, reportedly for around $400 million. And it added Novartis CEO Vas Narasimhan to its board.

Narasimhan has put numbers on the ambition: he says AI could cut drug development from about 12 years to 7 or 8, and roughly double the success rate of drug programs.

Why rare and neglected diseases

The focus is deliberately on diseases big pharma skips, where the biology is understood but the economics do not work. For many rare conditions, the science is not the bottleneck; the cost of a decade-long development program against a small patient population is. If AI genuinely compresses that timeline and cost, the economics of neglected diseases start to change.

It is worth being precise about where this stands. The work is early and preclinical. There is no pill on a shelf, and no guarantee there will be. What is new is the direction: an AI lab building not just tools for scientists but its own therapeutic programs.

The bigger picture

Claude Science follows the same logic as Claude Code. Anthropic built a product around how software engineers actually work, and it became one of the defining tools of the agent era. Now it is applying that playbook to research: a product for drug discovery, plus in-house programs to prove it works.

The ambition is clear. The company that powers the tools now wants to make the discoveries. Whether an AI lab can find your next medicine is a question that will take years to answer, but as of June 30, 2026, Anthropic is officially trying.
