Dexcom’s Dominance in CGM Market Faces Reality Check

Dexcom Inc’s recent showcase at the ATTD 2025 conference has left no doubt about its leadership in the continuous glucose monitoring (CGM) technology space. The company’s G7 15 Day system has set a new benchmark for accuracy, boasting a mean absolute relative difference (MARD) of 8.0%. This achievement solidifies Dexcom’s position as the most connected CGM brand, but does it translate to real-world success?

The writing is on the wall: healthcare providers are increasingly turning their backs on new medications for Type 2 diabetes care, opting instead for technology-driven solutions. A recent survey reveals a clear preference for CGM technology, a trend that spells trouble for pharmaceutical companies. Dexcom is poised to capitalize on this shift, but can it sustain its momentum?

The company’s stock price has taken a hit, with a moderate decline in value over the past day. However, the question remains: is this a temporary setback or a sign of a deeper issue? The recent sales of substantial amounts of shares by the CEO and other executives have raised eyebrows, and it’s hard to ignore the possibility that these transactions may have contributed to the decline in stock value.

• Key statistics:
  • Dexcom’s G7 15 Day system boasts a MARD of 8.0%, the most accurate CGM sensor available.
  • Healthcare providers prefer CGM technology over new medications for Type 2 diabetes care.
  • Dexcom’s stock price has declined moderately over the past day.
  • The CEO and other executives have sold substantial amounts of shares.
• The question remains: can Dexcom maintain its dominance in the CGM market and translate its technological advancements into real-world success? Only time will tell, but one thing is certain: the stakes are high, and the competition is fierce.
