Aehr Test Systems Shares Surge 35.86% on AI Burn-In Orders as $260M Volume Surges 831% to Rank 355th in Top 500 Trading Activity

On August 25, 2025, Aehr Test Systems (AEHR) surged 35.86% with a trading volume of $0.26 billion, marking an 831.01% increase from the previous day’s volume and ranking 355th in market activity. The stock’s sharp rise followed new orders for six ultra-high-power Sonoma burn-in systems from a leading hyperscaler, a major client developing custom AI processors. These systems will support high-volume production testing and burn-in for advanced AI chips, with deliveries expected from Aehr’s Fremont facility over the next two quarters.

The hyperscaler, a global provider of computing and storage infrastructure, has expanded its initial AI processor production plans and indicated intentions to add more AI devices in the coming year. Aehr’s CEO highlighted the strategic significance of these orders, emphasizing the growing demand for AI-specific Application-Specific Integrated Circuits (ASICs) among hyperscalers. These ASICs are optimized for tasks like large language model inference and image recognition, while reducing reliance on third-party hardware and improving energy efficiency. Aehr’s Sonoma systems, designed for cost-effective, high-density testing, position the company to capitalize on the AI chip market’s projected growth from $60 billion in 2023 to $600 billion by 2032.

Aehr’s technological edge lies in its Sonoma systems’ streamlined architecture, precision power delivery, and individual device handling, which enhance operational efficiency and reduce costs. The company’s ability to transition seamlessly from early-stage reliability testing to full production burn-in strengthens its competitive positioning in a market dominated by reliability demands. With hyperscalers accelerating custom AI chip development, Aehr’s partnership with a key client underscores its potential to expand revenue streams beyond traditional semiconductor testing segments.

The strategy of buying the top 500 stocks by daily trading volume and holding them for one day resulted in a total profit of $2,940 from December 2021 to August 2025, with a maximum drawdown of $-1,960.
