Blood Sugar Sensor Giant Loses 2 Trillion Won in a Day

Dexcom Inc. (NASDAQ: DXCM), a continuous glucose monitoring device maker, saw its shares plunge 8.14% on March 18, closing at $62.16 on the Nasdaq. Its market capitalization fell to about $23.9 billion (approximately KRW 32 trillion), erasing roughly $1.8 billion (about KRW 2.3 trillion) in a single day.

Since Jake Leach took the helm as CEO on January 1, the company has accelerated its transition to next-generation products by boosting investment in its G7 15-day continuous glucose monitoring system and AI-based features. It has also officially slated the discontinuation of its older G6 system’s production, effective July 1, 2026.

Headquartered in San Diego, Dexcom specializes in continuous glucose monitoring devices and, driven by sensors like the G7, held roughly 40% of the global CGM sensor market in 2024.
