AVGO vs MXL: Which Is the Better Buy in 2026?

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.

Reading it: AVGO 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. AVGO and MXL 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 AVGO and MXL 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.

Broadcom is one of the largest semiconductor companies in the world, plus a major enterprise software business after acquiring VMware in 2023. The semiconductor business has two main pieces. Networking and wireless silicon (Ethernet switches, optical components, custom ASICs for hyperscalers) is critical to AI data centers. Custom silicon (XPUs) for hyperscaler AI accelerators is a major growth driver: Broadcom designs custom AI chips for customers like Google (TPU), Meta (MTIA), and others.

MaxLinear is a fabless semiconductor company, meaning it designs chips and outsources manufacturing to foundries rather than owning fabs. Founded in 2003 and based in Carlsbad, California, it designs radio-frequency, analog, mixed-signal, and digital-signal-processing integrated circuits that go into other companies' equipment rather than being sold to consumers directly. Its products historically clustered in four areas: broadband (cable and fiber access chips, home gateways), connectivity (Wi-Fi and Ethernet), infrastructure (optical interconnect and wireless backhaul), and industrial and multi-market. For years the broadband and connectivity lines were the largest revenue sources, and they went through a deep downturn as customers worked off excess inventory, which pulled total revenue lower and pushed the company into losses.

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

• AVGO drivers: Custom AI accelerators (XPUs) for hyperscalers; AI networking silicon.
• MXL drivers: Optical data center ramp is the growth engine; Legacy broadband and connectivity stabilizing.

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 in custom AI silicon (top customers are Google, Meta, possibly OpenAI). For MXL, the central risk is that MaxLinear is still unprofitable on a GAAP basis, reporting an operating loss of about $17 million and a diluted loss per share of roughly $0.52 in Q1 2026, with trailing twelve-month net income around negative $137 million.

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 AVGO if you believe its drivers more; MXL 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 AVGO and MXL guides.

AVGO. Broadcom's premium valuation reflects the combination of dominant networking semiconductor positions, fast-growing custom AI silicon revenue, and high-margin enterprise software from VMware. P/E of 45x is high but supported by the AI-driven revenue acceleration.

MXL. Figures are approximate and tied to the asOf date; verify live numbers before acting. Because MaxLinear is not currently profitable on a trailing basis, its P/E is negative and the market values it on forward optical-data-center growth rather than current earnings, which is why the shares moved sharply after the Q1 2026 report. The valuation embeds a successful ramp and a manageable legal outcome, so these figures matter most as a gauge of how much optimism is already priced in.

Headline figures (approximate, early 2026): AVGO shows revenue (ttm) ~$60 billion (combined semis and software), operating margin ~50%, net income (ttm) ~$20 billion, eps (ttm) ~$4.30; MXL shows revenue (q1 2026 quarterly) ~$137 million, up 43% year over year, infrastructure revenue (q1 2026) ~$63 million, up ~136% year over year, gaap gross margin (q1 2026) ~57.5%, gaap diluted eps (q1 2026) ~-$0.52 (operating loss ~$17 million).

AVGO and MXL 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.
