DexCom: The Rival in the SensorNarrow moat

Abbott Laboratories (ABT) — moat facet

DexCom competes for the same diabetes patients with the same kind of sensor; Abbott's sensor sales are 1.6 times DexCom's whole revenue.

DexCom is the competitor Abbott meets most directly, because both sell continuous glucose monitors to the same people. DexCom's own 10-K says that in selling its systems "we compete directly with the Diabetes Care division of Abbott Laboratories"1, and lists Medtronic's diabetes business, which became a separate company called MiniMed, and Roche Diabetes Care after it2.

Glucose monitor revenue, 2025 ($M)7,600Abbott CGM sales4,662DexCom total revenueAbbott Form 10-K FY2025; DexCom Form 10-K FY2025
Abbott sells more sensors than DexCom sells everything.

The two are close in growth and far apart in size. DexCom's total revenue was $4,662.0 million in 2025, up 16%3. Abbott's glucose monitor sales were $7.6 billion, up 17.4%4, about 1.6 times DexCom's entire company5. For Abbott this is one product line in one of four segments; for DexCom it is the business.

The relationship differs in how each reaches the patient. DexCom sold $3,959.0 million of its $4,662.0 million through distributors in 20256, 84.9%7. Abbott says it has no customer whose loss would be material8. A rival that depends on a handful of distributors can be squeezed by them; Abbott, selling through many channels in 160 countries, is harder to squeeze.

Competition in this market is about accuracy, convenience and price to the payer. Abbott's own sensor growth slowed from 19.6% in the second quarter of 20259 to 9.5% comparable in the second quarter of 202610, while DexCom grew 16% for 202511.

DexCom's own channel is shifting. Its distributor revenue rose from $3,430.1 million in 2024 to $3,959.0 million in 2025, while direct revenue rose from $602.9 million to $703.0 million12. The rival is growing mostly through the same intermediaries that give it less control over price.

Over two years Abbott grew faster. DexCom's revenue rose from $3,622.3 million in 2023 to $4,662.0 million in 2025, 28.7%1314, while Abbott's sensor sales rose from $5.3 billion to $7.6 billion, 43.4%151617. DexCom's direct revenue was only $703.0 million in 202518.

The contest is measured in growth rates. Compare the two growth rates each year. When DexCom's is higher for a full year, the rival is taking the new patients the Libre franchise lives on.

The rival's pace; growing faster than Abbott's sensors for a year would mean it is taking the new patients.
