Chipmakers Face Valuation Tests as AI Spending Peaks
Nvidia, Broadcom, Micron, and Marvell report record revenues, but valuation gaps widen as supply constraints and customer concentration risks define the path to 2030.
The four largest U.S. semiconductor firms reported explosive revenue growth in their latest quarters, driven by insatiable AI infrastructure demand. Nvidia posted a 106% year-over-year increase to $96.2 billion, while Broadcom and Micron saw gains of 86% and over 300%, respectively. According to data from GN stocks/chips, these results reflect a supply-constrained market where production capacity, not customer interest, dictates earnings ceilings.
Management teams at these companies are projecting continued expansion, though the pace is moderating. Nvidia expects roughly 70% growth in fiscal 2028, a figure it attributes to manufacturing limits. Broadcom has secured supply to double its AI revenue to $115 billion next year, while Marvell targets $18 billion in fiscal 2028. The key distinction for investors is that these figures represent current momentum, not guaranteed long-term stability, as AI spending cycles begin to mature.
Nvidia and Broadcom Lead Growth
Nvidia’s data center segment generated $89 billion in its latest quarter, forming the backbone of global AI computing. With shares trading at approximately 14 times estimated fiscal 2028 earnings, the market is pricing in a plateau in growth after the current cycle. The company’s challenge remains maintaining its platform dominance against custom silicon alternatives.
Broadcom is capturing significant market share through custom accelerators, which accounted for 73% of its $16.7 billion AI revenue in the last quarter. CEO Hock Tan confirmed that the company has locked in the manufacturing supply required to reach $230 billion in AI revenue by fiscal 2028. At 18 times forward earnings, Broadcom’s valuation relies on consistent delivery to a concentrated group of hyperscale clients.
Micron and Marvell Face Risks
Micron Technology benefits from the memory bottleneck, reporting an 84.9% non-GAAP gross margin in its most recent quarter, nearly double the year-earlier figure. Despite revenue quadrupling to $41.5 billion, the stock trades at just 6 times fiscal 2027 estimates. This low multiple suggests the market assumes current record profits are temporary and cyclical rather than structural.
Marvell Technology presents the highest risk-reward profile, with revenue of $2.7 billion and a target of $18 billion by fiscal 2028. However, its valuation at 33 times expected earnings leaves little room for execution errors. Unlike its larger peers, Marvell’s business model depends heavily on winning new design contracts, making its forecast highly sensitive to competitive shifts in the custom chip market.
Valuation Diverges Across Supply Chain
The spread in price-to-earnings multiples across these four firms highlights differing investor confidence in their business models. Nvidia and Broadcom command premiums based on platform and custom chip dominance, while Micron trades at a discount due to its cyclical nature. Marvell’s high multiple reflects a bet on aggressive scaling, a strategy that requires flawless execution over the next four years to justify the cost.
