by | Jun 24, 2025 | Business of Biotech

If biotech were baseball, these five U.S. regions would be the major league teams. They dominate the field with the most life science companies, and they’re not just winning on numbers. These hubs offer brainpower, funding, lab space, and major players that keep the biotech innovation game strong.

Boston-Cambridge: The Biotech Brain Trust

  • Why it rules: Home to MIT, Harvard, and a swarm of VC firms with deep pockets, Boston is the undisputed biotech champ.
  • What draws companies: 1. Talent fresh from elite universities 2. Funding floodgates 3. Kendall Square: the densest biotech cluster on Earth
  • Top tenants: Moderna, Biogen, Vertex, Dana-Farber Cancer Institute
