Key Highlights

  • Monolithic Power beat expectations through 2026, with shares trading at high levels on AI-driven demand.
  • Its power-management chips convert and regulate electricity so AI processors receive exactly the power they need.
  • The company does not own factories, relying on outside manufacturers to stay flexible and capital-light.
  • Growing reliance on the data-center market concentrates risk, since its fortunes are becoming tied to the pace of AI investment.

The chips that power artificial intelligence consume staggering amounts of electricity, and getting that power to them cleanly and efficiently is a serious engineering challenge. Monolithic Power Systems (NASDAQ:MPWR) specialises in solving it, which has made power efficiency a crucial and lucrative part of the Nasdaq 100 AI build-out.

What Monolithic Power Does

Monolithic Power Systems designs power-management chips, the components that convert and regulate electricity so that other chips and electronic systems receive exactly the power they need. It sits in the technology sector. Its products are used across a wide range of markets, including data centres, cars, industrial equipment and consumer devices. Unusually, it does not own factories, instead focusing on chip design and relying on outside manufacturers, which keeps it flexible and capital-light while it concentrates on the engineering that sets its products apart.

AI Lifts Demand for Power Management

Monolithic Power has been a strong beneficiary of the AI boom. Through 2026 it beat expectations and its shares rallied, trading at high levels, as demand for its power-management chips rose with the build-out of AI data centres. The reason is that AI processors draw enormous amounts of power, and delivering that power efficiently, without wasting it as heat, requires sophisticated power-management components. As each generation of AI chips becomes more powerful and power-hungry, the challenge grows, and so does the value of the chips that manage it. This has shifted more of Monolithic Power's Business towards the fast-growing data-centre market, lifting its growth.

Why it Matters for the Nasdaq 100

Monolithic Power offers the index exposure to an essential but often overlooked part of the AI build-out: the power management that keeps AI chips running. Its results reveal how quickly data centres are being built and how demanding the latest AI chips are. As a member of the benchmark with a fast-growing data-centre business, it provides a focused way to participate in the same trend driving the largest chip names, through a specialised, high-margin niche.

Efficiency As a Growing Prize

The importance of power efficiency in AI deserves particular attention, because it is becoming a defining constraint. As AI systems scale, the electricity they consume has emerged as a major cost and a practical limit on how much computing can be packed into a data centre. Delivering power to the chips efficiently, minimising the energy lost as heat, directly affects running costs and how many processors can be housed in a given space. This makes advanced power-management chips increasingly valuable, and it plays to Monolithic Power's strength in efficient, high-performance designs. As AI chips grow ever more power-hungry, the company's addressable market expands, because more sophisticated power management is needed for each system. The risk is concentration: as data centres become a larger share of its business, its fortunes become more tied to the pace of AI investment.

The Risks to Weigh

Monolithic Power's growing reliance on the data-centre market concentrates risk, and AI spending could slow. Its valuation is very high, leaving little room for disappointment. Competition in power-management chips is significant. It depends on outside manufacturers, concentrating Supply risk. Its other markets, including cars and industrial, are cyclical. The shares are volatile, reflecting high expectations and shifts in sentiment about AI.

The Chips That Keep AI From Overheating

Readers should track Revenue from data-centre and AI-related products, the clearest measure of the AI opportunity, and watch the balance between that business and its more established markets. Commentary on demand from AI customers reveals the strength of the trend. Gross margins show the value of its specialised designs. Progress on next-generation power-management products indicates whether it can keep pace with ever-more-powerful AI chips. Finally, watch the pace of AI data-centre investment, because Monolithic Power's growth increasingly depends on the build-out of power-hungry systems its chips are designed to serve.
