Broadcom or Marvell? Valuation and Growth Math in AI Chips

Money is pouring into artificial intelligence stocks while demand still runs ahead of supply. The host opens with a clear thesis: the chip shortage stretches years out, and two custom-chip makers stand among its biggest winners, Broadcom and Marvell . Both design alternatives to off-the-shelf Nvidia silicon, yet they play at opposite ends of the stack. The question is as simple as the title: which stock is the better buy for the long run?

Every analysis starts with sales, because without sales there is no business. Broadcom shows off here: annual revenue of around 35 billion dollars in early 2024 has grown to nearly 90 billion over the trailing twelve months. Part of the jump comes from AI demand, part from folding in the 61-billion-dollar VMware acquisition. In its own investor release Broadcom reports 29.6 billion dollars of revenue for the third quarter of fiscal 2026 alone and guides to 34.8 billion for the fourth quarter.

Custom chips versus connectivity: two different fronts

Broadcom's story revolves around custom AI accelerators . Giants such as Alphabet co-develop tailored silicon with Broadcom instead of depending on Nvidia, pouring tens of billions into these programs. According to Anthropic, it agreed with Google and Broadcom on multiple gigawatts of next-generation TPU capacity coming online from 2027; on the OpenAI front a 10-gigawatt custom-accelerator collaboration with Broadcom is underway. Broadcom is setting standards on both the compute and the networking side of AI infrastructure.

Marvell plays the connectivity slice: chips that link and switch every data-center component into one giant working cluster. Its Marvell investor page advertises a mid-September AI Infra Summit showcase of the end-to-end connectivity portfolio, complemented by early-August memory and storage announcements on the same theme. No wonder Nvidia chief Jensen Huang named Marvell a trillion-dollar candidate. Still, the scale gap is enormous: Marvell's market value sits below 300 billion dollars while Broadcom exceeds 1.6 trillion.

Converting sales into profit sharpens the picture further. Broadcom's operating margin has climbed to 48.6 percent, up from about 5 percent in 2017. Marvell earns roughly a third of that at 16.8 percent, though the direction is up. The host concedes the smaller Marvell could expand margins through economies of scale as it grows. At Broadcom, the high-margin software arm offsets the lower-margin chip business and keeps the blended margin at the top.

Valuation: expensive growth or cheap quality?

The third yardstick is return on invested capital , what the company earns on each dollar of assets tied up in the business. Both firms outsource manufacturing, so asset-light models limit capital-intensive risk. Broadcom earns 25.75 percent, more than twice its weighted average cost of capital. Marvell manages 12.61 percent, barely covering its own cost of capital at roughly half of Broadcom's level.

And then the price tag: Marvell trades at a forward price-earnings ratio of 39 against 18 for Broadcom on the same basis, more than twice as expensive. The host's own discounted cash flow model puts Broadcom's fair value at 523 dollars versus a 353-dollar market price, implying about 48 percent upside over 12 to 18 months. For Marvell the math flips: 207 dollars of fair value against a 266-dollar quote, a 22 percent downside risk. The SeekReturns comparison shows the same profitability and valuation gap between the two stocks. Micron's September 30 earnings, formally announced on the Micron investor page, will reveal the true state of memory demand just after the video's release. The host states his position openly: he owns Broadcom shares and none of Marvell.
