What Happened?
Shares of semiconductor designer Power Integrations (NASDAQ: POWI) jumped 6.3% in the morning session after macroeconomic relief from declining Treasury yields and lower oil prices, coupled with robust artificial intelligence demand projections, boosted sentiment across the chip industry.
Per TipRanks, Nvidia CEO Jensen Huang reaffirmed long-term projections of $3 trillion to $4 trillion in global AI infrastructure spending by 2030, reinforcing structural growth expectations for hardware providers. This sentiment was further supported by solid AI cloud performance reported by Oracle, which signaled sustained enterprise appetite for data center expansion. Meanwhile, macroeconomic tailwinds offered additional momentum as falling Treasury yields and lower energy costs eased broader market pressures following a recent pullback. Together, these factors lifted optimism for key chipmakers, including Nvidia, Advanced Micro Devices, Micron Technology, and Intel, highlighting how broader economic signals and sustained cloud computing investments continue to drive sector-wide valuations.

What Is The Market Telling Us
Power Integrations’s shares are extremely volatile and have had 39 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The biggest move we wrote about over the last year was 11 months ago when the stock gained 20.2% on the news that the company detailed its collaboration with NVIDIA to advance its PowiGaN gallium-nitride technology for next-generation AI data centers. The partnership aimed to accelerate the transition to more powerful 800 VDC systems designed for megawatt-scale computer racks that power artificial intelligence. Power Integrations published a white paper at the 2025 OCP Global Summit explaining the benefits of its technology. According to the company, its new chips delivered greater power density and efficiency compared to competing devices. The announcement was significant as the demand for power in AI data centers has been rising rapidly, and this technology helped address that need by simplifying rack design and making more efficient use of space.
Power Integrations is up 41.8% since the beginning of the year, but at $52.90 per share, it is still trading 39.4% below its 52-week high of $87.35 from June 2026. Despite the year-to-date gain, investors who bought $1,000 worth of Power Integrations’s shares 5 years ago would now be looking at only $484.02.
