Arm vs. Credo Technology Group: Which Tech Stock Is a Better Buy in 2026?
Key Points
Arm provides the energy-efficient compute architecture powering nearly all of the world's smartphones.
Credo Technology Group is experiencing explosive growth by providing high-speed connectivity solutions for AI data centers.
Speed or staying power? Credo and Arm offer two very different ways to own the AI infrastructure build-out.
As artificial intelligence reshapes the global data landscape, infrastructure providers are seeing unprecedented demand. Investors must decide between the widespread architectural reach of Arm (NASDAQ:ARM) and the specialized connectivity of Credo Technology Group (NASDAQ:CRDO).
Arm provides the fundamental blueprint for processors found in billions of devices, while Credo focuses on the high-speed pathways that move data between servers. Both companies are essential to the expansion of modern computing, but they differ significantly in scale, growth rates, and how the market values their future potential.
The case for Arm
Arm designs the fundamental compute platforms that power almost every smartphone on Earth. Instead of manufacturing chips directly, the company licenses its intellectual property to other manufacturers, earning royalties and licensing fees. This capital-light model allows it to maintain a presence in over 350 billion chips worldwide while expanding into data centers and edge computing.
In FY 2026, revenue reached nearly $4.9 billion, representing a year-over-year increase of approximately 22.8%. The company reported net income of roughly $904.0 million for the period, which resulted in a net margin of close to 18.4%. This performance highlights the company's ability to maintain profitability as it gains traction in the semiconductor stocks market.
As of its March 2026 balance sheet, the debt-to-equity ratio is approximately 0.1x, which measures total debt relative to shareholder equity. The current ratio, a measure of a company's ability to pay short-term obligations, stands at nearly 6.0x. For the same fiscal period, free cash flow was close to $979.0 million. Note that stock-based compensation represented roughly 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 Credo Technology Group
Credo Technology Group provides high-speed connectivity solutions that enable data to travel efficiently through modern AI data centers. The company sells specialized products like Active Electrical Cables and optical transceivers to major cloud providers. Key commercial partners include Oracle (NYSE:ORCL) and Microsoft (NASDAQ:MSFT). Customer concentration like this adds a layer of risk to the business, as the top ten customers represent roughly 90% of total revenue.
In FY 2026, revenue reached nearly $1.3 billion, a massive jump of approximately 205.7% from the previous year. The company posted net income of close to $472.3 million, resulting in a net margin of roughly 35.4%. This surge in revenue and profitability reflects the intense demand for high-speed connectivity as hyperscalers scale their artificial intelligence infrastructure.
As of its May 2026 balance sheet, the debt-to-equity ratio is 0.0x, indicating the company has no debt. Its current ratio is approximately 10.2x, suggesting a very strong liquidity position for covering immediate liabilities. Free cash flow for the period was close to $407.0 million. Note that stock-based compensation represented roughly 39.3% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.
Risk profile comparison
Arm faces risks related to its high dependency on the smartphone market, where growth has historically been cyclical. It also faces increasing competition from open-source architectures, which offer royalty-free alternatives to its proprietary designs. Furthermore, geopolitical tensions involving international trade could impact its ability to license technology in key global markets.
Credo Technology Group deals with significant revenue concentration, meaning the loss of a single hyperscale customer could severely impact financial results. The company competes against well-established giants such as Broadcom (NASDAQ:AVGO), Marvell Technology (NASDAQ:MRVL), and Astera Labs (NASDAQ:ALAB). It also relies on a fabless model, depending on Taiwan Semiconductor Manufacturing Company (NYSE:TSM) for manufacturing, which exposes it to potential supply chain disruptions.
Valuation comparison
Credo appears more attractively valued than Arm, as it trades at much lower multiples of sales over the past twelve months and future earnings estimates.
| Metric | Arm | Credo Technology Group |
|---|---|---|
| Forward P/E | 139.3x | 30.5x |
| P/S ratio | 64.3x | 22.5x |

Which stock would I buy in 2026?
I'd go with Credo Technology. The company has strung together one of the most impressive growth streaks in the semiconductor industry, with revenue approaching or exceeding triple digits for several consecutive quarters, gross margins above 70%, and guidance pointing to more than 85% revenue growth for the full year. Its connectivity chips and optical products are becoming essential inside the AI data centers being built by every major hyperscaler.
Arm's royalty model is one of the more durable business models in semiconductors. Its architecture powers virtually every smartphone and is rapidly expanding into AI data centers, with royalty revenue more than doubling in that segment. The business compounds reliably across billions of devices and does not depend on any single product cycle. For investors who value consistency above acceleration, it is a strong long-term hold.
Customer concentration is the one risk worth watching at Credo, since a handful of hyperscalers drive most of its revenue. But the demand behind those relationships keeps growing, and the results keep arriving ahead of expectations. For investors comfortable with that trade-off, Credo's growth trajectory is simply in a different league right now.
