Better Artificial Intelligence Stock: Arm vs. Marvell Technology

As the artificial intelligence revolution matures, investors are scrutinizing infrastructure providers. Choosing between Arm Holdings (NASDAQ:ARM) and Marvell Technology (NASDAQ:MRVL) involves weighing architectural dominance against high-speed data center connectivity leadership.

Arm provides the energy-efficient processor blueprints used in nearly every smartphone and an increasing number of cloud servers. Marvell specializes in data infrastructure silicon, helping move and store massive amounts of information. Both are critical to modern computing, but their financial profiles and market roles offer distinct paths for growth in the tech sector.

The case for Arm

Arm functions as the foundation of modern computing by licensing its energy-efficient processor designs to other chipmakers. This licensing and royalty model allows the company to reach vast markets, including mobile, automotive, and data centers, without the high costs of manufacturing. The company does not disclose individual customer names in its latest annual report, but its blueprints are fundamental to the global smartphone supply chain.

In its 2026 fiscal year (FY), ended March 31, revenue reached $4.9 billion, representing 22.8% growth compared to the $4.0 billion reported in the prior year. This expansion was accompanied by net income of $904.0 million, yielding a net margin of 18.4%. While this net margin is slightly lower than the 19.8% seen in FY 2025, it remains significantly higher than the 9.5% recorded in FY 2024.

Arm maintains a debt-to-equity ratio of 0.1x, which means total debt is a small fraction of shareholder equity. Its current ratio is 6.0x, indicating a strong ability to cover short-term debts with current assets. Free cash flow reached $979.0 million, though note that stock-based compensation (SBC) represented 69% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.

The case for Marvell Technology

Marvell is a dominant force among semiconductor stocks, providing the infrastructure needed for high-performance AI networking. The company focuses on high-speed connectivity and storage solutions for the data center market, which accounted for roughly 74% of revenue in FY 2026, ended Jan. 31. Customer concentration like this adds a layer of risk to the business, as two customers each account for more than 10% of total revenue.

In FY 2026, revenue reached $8.2 billion, a significant jump of nearly 42.1% from the $5.8 billion generated in FY 2025. This growth resulted in a net income of $2.7 billion, a massive improvement from the net losses reported in the previous two years. The net margin for this period reached 32.6%, showcasing the high profitability of its data center silicon portfolio.

Marvell carries a debt-to-equity ratio of 0.3x, showing a relatively conservative use of debt. The current ratio is 2.0x, which measures how well the company can meet short-term obligations using its current assets. Free cash flow for the year was $1.4 billion, but note that stock-based compensation represented roughly 33.8% of operating cash flow.

Risk profile comparison

Arm faces risks from the rise of open-source architectures that could eventually challenge its proprietary designs. Furthermore, as large technology companies like Nvidia (NASDAQ:NVDA) and Qualcomm (NASDAQ:QCOM) develop more of their own custom silicon, they may seek to reduce their reliance on external blueprints. Arm also competes against Intel (NASDAQ:INTC) in the server market, where the transition to energy-efficient chips is still in its middle stages.

Marvell deals with extreme revenue concentration, as its ten largest customers represent roughly 82% of its total sales. This makes the company vulnerable to any design changes or spending cuts from a few major hyperscalers. Geopolitical risks also loom large, as Marvell depends on third-party manufacturing in Taiwan and faces potential export restrictions that could limit sales to China. Additionally, it faces stiff competition in the networking space from Broadcom (NASDAQ:AVGO) and Cisco Systems (NASDAQ:CSCO).

Valuation comparison

Marvell looks cheaper than Arm using the Forward P/E, based on future earnings estimates, and the P/S ratio, which tracks sales over the past twelve months.

Which stock would I buy in 2026?

Arm and Marvell Technology are experiencing robust revenue growth, making both compelling semiconductor companies to invest in. While Arm is known for its dominance in the smartphone sector, it has expanded into AI central processing units (CPUs) for data center infrastructure. The company introduced its Arm AGI CPU in March.

While Arm is doing well, Marvell is the stock I would buy right now. Its AI business is expanding at a rapid pace, as evidenced by its record revenue of $2.7 billion in its fiscal second quarter, ended Aug. 1. The sum represents outstanding 37% year-on-year growth. That's just the start.

Marvell produced revenue of $8.2 billion in FY 2026, but on Oct. 6, it announced that it expects to hit $20 billion by FY 2028. The company even set a FY 2031 target of $70 billion to $90 billion in sales. That kind of incredible growth in the coming years points to the outsized demand it's seeing for its AI solutions.

I anticipated Marvell would do well amid the AI revolution, which is why I bought shares, but the revenue forecasts it shared recently showed just how much of a boost artificial intelligence demand is delivering, and the company is successfully capturing its share of this massive market. Adding to this, its share price valuation is far superior to Arm’s, making Marvell the no-brainer stock to buy between these two semiconductor giants.
