ALAB vs CRDO: How Astera Labs and Credo Technology Compare (2026)

Same yardstick, side by side (as of July 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.

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.

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. ALAB and CRDO 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 ALAB and CRDO 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.

Astera Labs makes purpose-built connectivity hardware and software for AI and cloud infrastructure. Its core products are Aries PCIe and CXL smart DSP retimers (which preserve signal integrity so data can travel farther and faster inside a server), Taurus Ethernet smart cable modules (for high-speed 400G and 800G links between racks), Leo CXL memory controllers (which enable memory expansion and pooling), and the newer Scorpio fabric switches (P-Series PCIe switches and the X-Series AI fabric switch for connecting large GPU clusters). The company makes money by selling these chips and modules to hyperscalers, AI accelerator vendors, and system builders, and pairs them with a software layer for diagnostics and fleet management, positioning itself as a connectivity platform rather than a single-chip supplier.

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.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• ALAB drivers: Rising connectivity content per AI cluster; The Scorpio fabric switch ramp.
• CRDO drivers: AEC adoption inside AI racks; AI bandwidth growth.

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 significant, with a large share of revenue tied to a handful of hyperscalers and AI accelerator vendors, so the loss or slowdown of one large customer would be material. For 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.

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 ALAB if you believe its drivers more; CRDO 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 ALAB and CRDO guides.

ALAB. Astera Labs trades at a steep premium on both sales and earnings, reflecting expectations of sustained rapid growth in AI connectivity. The valuation depends on continued hyperscaler capex and successful product ramps like Scorpio. A high multiple compresses quickly if growth decelerates or a key customer relationship changes, which is the central tension for prospective investors weighing the stock.

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.

Headline figures (approximate, June 2026): ALAB shows revenue (ttm) ~$1.0 billion (FY2025 was ~$852 million), revenue growth (q1 2026 yoy) ~93% (FY2025 was ~115%), gross margin (non-gaap) ~76% (Q1 2026), market cap ~$65 billion; 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.

ALAB and CRDO 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.
