CRDO vs MRVL: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
MRVL is the larger of the two ($168.34B market cap): the incumbent the market prices for continued execution (30.05x forward earnings, beta 2.20). CRDO is the smaller challenger ($38.60B), cheaper on forward earnings (22.81x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
CRDO vs MRVL: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | CRDO | MRVL | What it tells you |
|---|---|---|---|
| Market cap | $38.60B | $168.34B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 22.81 | 30.05 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 82.80 | 64.45 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 3.20 | 2.20 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 54% of range | 47% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 18.60 | 9.02 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: CRDO is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how CRDO and MRVL affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CRDO and MRVL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CRDO and MRVL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Credo Technology (CRDO) do?
Credo Technology designs high-speed connectivity products that move data inside and between AI and cloud data centers. Its best-known product is the active electrical cable (AEC), branded ZeroFlap, a copper cable with Credo's own chips built in that carries data over short distances more cheaply and reliably than optical cables; Credo also sells SerDes IP and chiplets, line-card and retimer ICs, optical digital signal processors (DSPs), and OmniConnect memory connectivity. The company makes money by selling these chips and cables, mostly to hyperscale cloud operators and the networking equipment makers that serve them, with AEC and integrated-circuit demand driving the recent ramp.
What does Marvell Technology (MRVL) do?
Marvell Technology designs semiconductors for data infrastructure: networking silicon (Ethernet, optical, switching), storage controllers, custom silicon (ASICs) for hyperscalers, and 5G wireless infrastructure. The company has positioned itself as the second-largest designer of custom AI silicon for hyperscaler customers, behind Broadcom. Marvell's custom silicon revenue from Amazon (Trainium), Microsoft (Azure custom chips), and Meta has grown rapidly through 2024-2025.
CRDO vs MRVL: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- CRDO drivers: AEC adoption inside AI racks; AI bandwidth growth.
- MRVL drivers: Custom AI silicon (ASICs) for hyperscalers; Optical interconnects for AI data centers.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Customer concentration is the central risk: a large share of revenue has come from a few hyperscalers, and in some quarters a single customer has represented the majority of sales, so an order pause or design loss at one account can move results sharply. For MRVL, customer concentration in custom AI silicon (a few hyperscalers dominate revenue).
CRDO or MRVL: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CRDO if you believe its drivers more; MRVL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CRDO and MRVL guides.
CRDO vs MRVL: the full fundamentals
CRDO. Credo trades at a steep premium to its earnings and sales, reflecting the speed of its AI-driven revenue ramp and high margins. The trailing P/E has been well over 90x, with a lower forward multiple as analysts model continued growth. At this valuation the stock is sensitive to any slowdown in hyperscaler AI spending or a stumble at a major customer.
MRVL. Marvell trades at a premium multiple reflecting the AI custom silicon growth story. The valuation depends on continued execution against the AI thesis; multiple compresses quickly if growth disappoints.
Headline figures (approximate, June 2026): CRDO shows revenue (fy2026) ~$1.3 billion, revenue growth (yoy) ~200% (roughly tripled from ~$437M in FY2025), non-gaap gross margin ~68%, net income (fy2026) ~$472 million; MRVL shows revenue (ttm) ~$6 billion, operating margin ~25% (improving as custom silicon mix grows), net income (ttm) ~$1 billion, eps (ttm) ~$1.30.
The bottom line: CRDO vs MRVL
CRDO and MRVL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CRDO and MRVL exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between CRDO and MRVL?
+
Credo Technology designs high-speed connectivity products that move data inside and between AI and cloud data centers. Marvell Technology designs semiconductors for data infrastructure: networking silicon (Ethernet, optical, switching), storage controllers, custom silicon (ASICs) for hyperscalers, and 5G wireless infrastructure. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is CRDO or MRVL the better stock?
+
Neither is universally better. MRVL is the larger incumbent; CRDO is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, CRDO or MRVL?
+
On forward P/E (as of August 2026), CRDO trades at 22.81x and MRVL at 30.05x, so CRDO is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both CRDO and MRVL?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of CRDO vs MRVL?
+
CRDO: Customer concentration is the central risk: a large share of revenue has come from a few hyperscalers, and in some quarters a single customer has represented the majority of sales, so an order pause or design loss at one account can move results sharply. Credo competes with much larger and well-funded rivals, including Broadcom and Marvell, plus newer entrants like Astera Labs, all targeting the same connectivity sockets. Revenue is tied to AI data-center capex, which is cyclical and could slow if hyperscaler spending cools. The stock also carries a premium valuation, which leaves little room for disappointment. MRVL: Customer concentration in custom AI silicon (a few hyperscalers dominate revenue). Competition with Broadcom for custom silicon is intense; losses on individual customer deals would matter materially.
