Analysis of Ketone Sensors and Type 2 Non-Insulin CGM Market

Sector ReportEquitiesHealth Care

This deep dive analysis explores the stable competitive duopoly in the CGM market between Abbott and DexCom, focusing on the massive $4 billion growth opportunity in Type 2 non-insulin patients.

Key Takeaways

  • 1.The continuous glucose monitor (CGM) market share between DexCom and Abbott remains stable, with survey data showing split future prescribing intent and low competitive switching rates.
  • 2.The Type 2 non-insulin (T2 NI) market represents the next major growth leg, potentially becoming a $4 billion market by 2030 if CMS reimbursement is established.
  • 3.Dual-analyte ketone sensors face a mixed outlook; while they address a multi-billion dollar DKA hospitalization burden, clinical data showing CGM effectiveness in reducing DKA without ketone sensing suggests the product may remain niche.
