3 US Semiconductor Stocks Tied To Federal R&D Spending Investors Should Watch

The US government is writing real checks to semiconductor R&D, not just policy speeches, and that kind of money often reshapes which stocks matter. Fresh funding for fusion projects, power chips and high purity materials is pulling a spotlight onto a tight group of US listed players that sit close to this capital. This article walks through three such stocks exposed to this news and explains why their stories now demand your attention.

The three examples below are a starting sample only, and the full screen surfaced 20 more US power semiconductor and materials stocks with equally compelling stories that are not covered here. To identify and analyze the highest conviction ideas in this theme, head straight into the US Power Semiconductor & Materials Beneficiaries of Federal R&D Support screener.

Texas Instruments (TXN)

Overview: Texas Instruments is a large US-based analog and power semiconductor manufacturer supplying power-management and embedded chips into industrial, automotive and energy-related equipment.

Operations: Texas Instruments generates about US$15.6b from Analog and US$2.9b from Embedded Processing, with around US$7.5b coming from customers in the United States.

Market Cap: US$253.7b

Texas Instruments matters for this screen because its power-management portfolio and sizable US manufacturing footprint align closely with the federal push into domestic chip and energy technologies, which is where new R&D dollars are flowing.

"The buildout of U.S.-based 300mm analog manufacturing is expected to structurally improve cost efficiency, support higher gross margins, and increase supply-chain resilience. As these assets ramp and utilization normalizes, TXN should regain its historical free-cash-flow profile, supported by diversified end-market exposure across industrial, automotive, aerospace/defense, and energy infrastructure."

How that capital build interacts with an unresolved pressure on future returns will likely be central to how investors judge Texas Instruments.

That tension is exactly what the full narrative for Texas Instruments unpacks, separating temporary margin pressure from long term potential as federal R&D accelerates around Texas Instruments.

AXT (AXTI)

Overview: AXT supplies compound semiconductor substrates like indium phosphide and gallium arsenide that underpin high speed data, RF and power related electronics.

Operations: AXT generates about US$125.5 million from semiconductor equipment and services, with most revenue tied to compound substrate and related material sales.

Market Cap: US$3.7b

AXT fits this R&D driven screen as a pure play materials specialist, plugging directly into US efforts to secure advanced power and photonics supply chains and giving investors exposure to the substrate layer of the AI and energy transition build out.

"Accelerating global demand for high-speed data center connectivity and AI infrastructure is driving increased adoption of indium phosphide substrates, where AXT is a top supplier with 40% share; as export permit headwinds ease, this pent-up demand is expected to produce sharp revenue growth and improved utilization of manufacturing capacity."

The key swing factor is how one pressure on pricing power eventually feeds through to the margins investors are watching most closely.

That pricing squeeze is exactly what the full narrative for AXT breaks down, showing where pressure might be masking AXT’s upside as substrate demand accelerates.

Power Integrations (POWI)

Overview: Power Integrations designs high-voltage power-conversion chips used in AI data centers, electric vehicles, renewables, and energy-efficient industrial equipment.

Operations: Power Integrations generates about US$449 million from integrated circuits and related components, with sales spread across the Americas, wider Asia-Pacific, and Hong Kong/China.

Market Cap: US$2.6b

Power Integrations matters in this screen because its high-voltage GaN and mixed-signal IC portfolio sits directly in the power electronics stack that federal R&D money is targeting to accelerate AI data centers, clean energy, and grid infrastructure.

"Although Power Integrations reports healthier recent quarters with improving margins, the 4.2% annual revenue decline and 10.7% annual EPS decrease over the past five years indicate that efforts to pivot toward higher voltage architectures in AI data centers, EVs, and energy infrastructure may not fully offset legacy weakness, which could limit long term revenue and earnings."

What happens to Power Integrations margins if a single assumption about how quickly high-voltage GaN wins AI power sockets proves too optimistic?

If that GaN adoption curve matters to you, read the full narrative for Power Integrations to see how Power Integrations risk could be masking accelerating upside potential.
