Allegro and MPS Shares Are Surging Because AI Is Spreading Beyond Chips-Here's the Real Story

AI is broadening into power, sensing, and interconnect

This rally looks broader than a simple chip rebound. The market is starting to price the enablement layer underneath AI clusters: power delivery, sensing, and interconnect components that matter more as systems scale.

MPS gave that thesis a fresh proof point with record Q1 2026 revenue of $804.2 million, up 26.1% year over year. Its Communications end market also grew 33% sequentially, helped by power solutions for optical modules and switches. That matters because AI is increasingly a systems problem, not just a compute problem.

The backdrop reinforces that point. Strong results from Intel and positive industry-wide forecasts lifted the broader semiconductor group, while Omdia significantly raised its 2026 semiconductor revenue outlook. This looks less like one stock chasing a narrative and more like the AI trade is widening across the infrastructure stack.

That does not mean the move is risk-free. MPS can be volatile, and supply-chain jitters have already hit the sector when a broad-based sell-off hit the semiconductor sector. But if AI spending keeps rising, investors are likely to focus less on short-term noise and more on which suppliers are actually capturing the added demand.

Monolithic Power Systems is already converting AI demand into earnings

MPS is the cleaner test of whether AI power delivery is becoming a real earnings engine rather than just a market story. So far, the numbers support that view.

Scale is showing up in the results

Full-year 2025 revenue reached $2.8 billion, up 26.4%. MPS is not just selling into AI enthusiasm; it is monetizing the infrastructure layer that becomes more valuable as compute density rises.

Q1 2026 strengthened that read-through. The company delivered record quarterly revenue of $804.2 million, up 26.1% year over year. Communications demand stayed strong, Automotive and Enterprise Data pipelines continued to accelerate, and MPS also sampled its first high-speed interface products for DDR5 at major customers. That points to a platform growing across several AI-linked areas rather than relying on a single lane.

The premium valuation is part of the debate

MPWR also trades like a company already in the growth phase of that story. Its shares have ranged from $438.90 to $1,256.20 over the past year, and the stock was hit when sharp selloff behavior spread during the broadest global chip selloff of the year. Bulls view that premium as justified by current earnings power. Bears see an expensive analog name that could be vulnerable if AI capex slows.

For now, the evidence still leans bullish: MPS is one of the clearest listed ways AI infrastructure spending is reaching further down the stack.

Allegro looks earlier on the adoption curve, which changes the risk-reward

Allegro does not look as far along as MPS on the earnings curve. That makes its setup different, and it makes the next few weeks more important.
