Broadcom vs. Marvell Technology: 1 Critical Metric Decides the Better Custom AI Chip Stock

August 23, 2026 - 21:59

The race to build custom artificial intelligence chips is heating up, and two companies are leading the pack: Broadcom and Marvell Technology. Both firms design application-specific integrated circuits, or ASICs, for hyperscale cloud providers like Google, Meta, and Microsoft. These chips are tailored for specific AI workloads, offering better performance and lower power use than the general-purpose GPUs from Nvidia. As demand for AI infrastructure explodes, investors are trying to figure out which of these two custom chip designers will come out on top.

The answer may come down to a single critical metric: revenue concentration. Broadcom has a much more diversified revenue base. While its AI chip segment is growing fast, it still makes a large chunk of money from networking, storage, and legacy semiconductor products. That diversity gives Broadcom stability. If one customer pulls back on AI spending, the company can lean on other divisions. Marvell, on the other hand, is far more dependent on a handful of big AI customers. A large portion of its recent growth comes from just two or three hyperscalers. That creates higher risk. If one of those clients delays a project or shifts to an in-house design, Marvell's revenue could take a serious hit.

But there is another side to that coin. Marvell's higher concentration also means more upside if those customers ramp up orders. The company is smaller, so a single big contract can move the needle dramatically. Broadcom's size makes it harder to post the same percentage gains. In the last quarter, Broadcom's AI revenue nearly doubled year over year, but Marvell's AI-related sales grew even faster on a percentage basis. That is the core trade-off: Broadcom offers safety and scale, while Marvell offers explosive growth potential with higher risk.

Looking ahead, the custom AI chip market is projected to grow at a compound annual rate of over 30 percent through 2028. Both companies are well positioned to benefit. But the critical metric to watch is customer concentration. If you want a steadier ride, Broadcom is the pick. If you can stomach volatility for a chance at bigger returns, Marvell might be the play. Either way, the demand for custom silicon is not slowing down, and both stocks are riding that wave. The real question is which one you can sleep with at night.
