The global continuous glucose monitoring (CGM) market is expanding as healthcare providers and patients increasingly adopt real-time glucose tracking technologies for diabetes management. Demand is supported by the rising prevalence of diabetes, improvements in sensor accuracy, growing interest in personalized healthcare, and the integration of glucose-monitoring devices with smartphones and insulin-delivery systems. CGM devices help users monitor glucose fluctuations throughout the day, identify patterns, and make more informed treatment decisions.

For accurate market research, it is important to distinguish the continuous glucose monitoring devices market from the broader blood glucose monitoring market. Grand View Research publishes separate reports for these categories, and their market sizes and growth rates should not be treated as interchangeable.

Market Segmentation: Key Figures

Grand View Research's 2025 segment shares highlight where the market is currently concentrated:

• By product: Sensors led with 62.8% of revenue.

• By connectivity: Bluetooth led with 57.3% of revenue.

• By indication: Type 1 diabetes led with 64.9% of revenue.

• By distribution channel: Pharmacies led with 59.4% of revenue.

• By region: North America led with 63.3% of revenue. 

These figures show the importance of recurring sensor demand, wireless connectivity, diabetes-management needs, and established distribution networks. At the same time, faster adoption among Type 2 diabetes patients and growth in online sales provide additional opportunities for market participants.

Key market factors include:

• Rising diabetes prevalence: Growing numbers of people living with Type 1 and Type 2 diabetes are increasing the need for consistent glucose monitoring.

• Technology improvements: Smaller sensors, simpler application processes, improved connectivity, and more user-friendly interfaces are making CGM systems easier to incorporate into everyday life.

• Digital healthcare adoption: Smartphone applications and remote-monitoring platforms enable users and clinicians to review glucose trends and respond to changes.

• Greater emphasis on preventive care: CGM data can help users understand how meals, exercise, sleep, and medication affect glucose levels.

Grand View Research's country-level research illustrates the expansion of this technology. For example, the China continuous glucose monitoring devices market was estimated at USD 231.4 million in 2024 and is projected to reach USD 1,142.1 million by 2033, growing at a CAGR of 19.4% from 2025 to 2033. These are China-specific figures and should not be presented as global market values. 

Market Competitors & Shares

The global CGM devices market includes established medical technology companies and emerging developers competing through sensor innovation, accuracy, connectivity, wear duration, and integration with diabetes-management systems. The current Grand View Research market summary does not provide comparable market-share percentages for individual companies, so the following overview focuses on their primary strategies rather than presenting unsupported company shares. 

Key Driving Trends in 2026

- Expansion of over-the-counter CGM products: CGM adoption is extending beyond traditional insulin-dependent patient groups. Products such as Dexcom Stelo and Abbott Lingo target eligible consumers interested in glucose patterns, lifestyle changes, and metabolic health. Broader availability may introduce CGM technology to new customer groups, although device indications and suitability differ.

- Sensor innovation and miniaturization: Sensors accounted for 62.8% of global CGM devices market revenue in 2025, making them the leading product segment. Their importance reflects the need for recurring replacement and continuous glucose measurement. Manufacturers are focusing on compact designs, improved accuracy, easier application, and longer wear periods. 

- Bluetooth connectivity and digital integration: Bluetooth held 57.3% of market revenue in 2025. Wireless connectivity enables glucose readings to reach compatible smartphones, receivers, and healthcare platforms. These systems help users review glucose trends, share information with clinicians, and connect monitoring data with broader diabetes-management routines. 

- Growing demand among people with Type 2 diabetes: Type 1 diabetes represented 64.9% of market revenue in 2025, reflecting the importance of continuous monitoring for people who require ongoing insulin management. Meanwhile, the Type 2 diabetes segment is expected to grow as awareness, clinical use, and access expand. The growing availability of devices for selected non-insulin users may also broaden adoption. 

- Integration with automated insulin delivery: CGM systems are increasingly connected with insulin pumps and automated insulin-delivery technologies. This integration allows glucose readings to inform insulin-management decisions and can reduce the need for users to manually coordinate separate devices. Compatibility, clinical indications, and regulatory approvals remain important considerations.

- Online sales and consumer access: Pharmacies accounted for 59.4% of market revenue in 2025, supported by their accessibility and established role in healthcare distribution. E-commerce is also gaining importance, with the channel projected to grow as manufacturers develop direct-to-consumer offerings and online purchasing options.
