AI Power Semiconductor Stocks Plummet... $400 Million Vanished in a Day

Navitas Semiconductor Corp. (NASDAQ: NVTS) shares plunged more than 9% on June 24 on the Nasdaq, closing at $19.38 and wiping out roughly $400 million (₩500 billion) in market value in a single day. Trading volume surged to over 24.39 million shares—well above its average—while market capitalization fell to about $4.5 billion (₩6 trillion).

The stock had also fallen nearly 9% the previous day as sales declined by over 30% year-over-year and losses persisted. Analysts point to insider share sales and mixed ratings as contributing to a correction after a prior rally (MarketBeat).

In its 2025 results, the company reported nearly a 50% drop in annual revenue and widening losses. Nevertheless, Navitas is accelerating its strategic shift toward AI data centers and power infrastructure—securing designation as NVIDIA’s 800 V AI data-center power-architecture partner and entering a long-term GaN production agreement with GlobalFoundries (Navitas IR).

Navitas Semiconductor, a next-generation power-semiconductor specialist, develops GaN power ICs and SiC devices targeting high-power markets such as AI data centers, power grids, high-performance computing, and industrial electrification (Navitas IR).

By reducing its exposure to low-power consumer products like mobile chargers and refocusing on AI and energy infrastructure, the company—still modest in revenue scale and unprofitable—is viewed as a high-growth opportunity with valuation pressures (Navitas IR).
