ON Semiconductor Corp. (onsemi) reached an all-time high of $127.00. The stock hit this record on May 27, 2026. Investor enthusiasm for artificial intelligence and next-generation automotive technology drove the rally. Heavy institutional capital is flowing into the essential hardware sector.

High demand for silicon carbide (SiC) power modules fueled the milestone. These modules provide critical energy efficiency for data centers and electric vehicles. An industry-wide supply crunch further bolstered stock prices as chip demand outpaces production.

The broader semiconductor sector experienced a significant lift from the surge. This movement helped push the S&P 500 and Nasdaq Composite to new record highs.
