The case for owning Marvell almost always opens with custom AI chips, and that is the part of the story where Marvell is structurally second. The company and Broadcom are the two names that turn hyperscaler in-house silicon designs into manufacturable chips, the application-specific processors that Amazon, Microsoft, Google and Meta increasingly favor over off-the-shelf GPUs for inference. But Marvell holds roughly 15 percent of that market against Broadcom’s 55 to 60 percent, and Counterpoint expects Broadcom to command about 60 percent of custom AI silicon by 2027.
