As major technology companies gear up to announce their capital spending plans, investors are eyeing semiconductor stocks poised to benefit from the increased investment in data centers and AI infrastructure. Companies like Nvidia (NVDA), Broadcom (AVGO), and Marvell Technology (MRVL) are central to this build-out, with Nvidia emerging as a top pick due to its strong growth and attractive valuation.
The article highlights the significant increase in capital expenditure by tech giants such as Alphabet, Amazon, Meta, and Microsoft, collectively planning over $700 billion in investments. This surge is driving demand for advanced chips and networking solutions provided by these semiconductor firms.
As the fiscal first quarter earnings season approaches for tech giants like Microsoft (reporting Oct. 28), investors in the semiconductor space are keenly focused on capital expenditure. This metric reveals the planned investments in data centers and other significant projects, a crucial indicator for chip stocks.
The trend this year is clear: capital spending is on the rise. Alphabet has revised its 2026 outlook to $195 billion - $205 billion, while Amazon has increased its estimate to approximately $220 billion. Meta Platforms anticipates spending between $130 billion and $145 billion, nearly doubling its 2025 expenditure. Microsoft's projected spending for calendar 2026 is around $175 billion, bringing the combined total for these four tech titans to over $700 billion.
This surge in spending directly benefits chip manufacturers poised to supply the necessary components. Nvidia (NVDA), Broadcom (AVGO), and Marvell Technology (MRVL) each play a vital role in this infrastructure build-out. Despite recent market fluctuations, all three stocks are trading below their record highs, presenting a potentially opportune moment for investors.
1. Nvidia: Dominating the AI Hardware Market
Nvidia is at the forefront of AI development, supplying the complete systems required for training and running artificial intelligence models. Its portfolio includes graphics processing units (GPUs), processors, and networking gear that form the backbone of modern data centers.
Hyperscale customers, comprising the largest cloud and internet companies, accounted for roughly half of Nvidia's $96.2 billion in revenue for its fiscal second quarter of 2027. Demand continues to surge, with Nvidia's data center revenue experiencing a remarkable 117% year-over-year increase in fiscal Q2. The company has forecast approximately $108 billion in revenue for fiscal Q3, signaling continued strong performance.
Despite its dominant position, Nvidia's stock trades at a relatively attractive valuation of about 14 times earnings, based on analysts' fiscal 2028 consensus. Trading near $229, it remains less than 5% below its recent record close.
2. Broadcom: Powering Custom AI Silicon
Broadcom has carved out a significant niche by collaborating with major tech firms to design custom AI chips. Examples include Alphabet's Tensor Processing Units (TPUs) and Meta's AI accelerators (MTIA). Additionally, Broadcom provides the Ethernet switches essential for connecting these powerful processors.
The company's AI semiconductor revenue saw an impressive 221% year-over-year increase, reaching $16.7 billion in fiscal Q3 2026. AI chips now constitute 56% of Broadcom's total revenue, with custom silicon accounting for 73% of that AI segment. Management projects fiscal Q4 AI revenue to climb to $21.7 billion, a 236% increase.
Beyond custom solutions, Broadcom also supplies critical components like Tomahawk 6 switches to these same large customers. The stock, currently trading around $357, is approximately 26% below its June 2 record high, with a P/E ratio of about 19 times fiscal 2027 earnings estimates.
3. Marvell: Connecting the AI Ecosystem
Marvell Technology, the smallest of the three, plays a crucial role in connecting the AI infrastructure. The company specializes in optical digital signal processors, essential for high-speed data transfer between AI servers, as well as switches and custom chips for cloud providers.
Data centers represent a significant 79% of Marvell's revenue. This segment has shown accelerating growth, with a 46% year-over-year increase in fiscal Q2 2027 and a guided 75% growth for fiscal Q3. However, Marvell's stock, trading near $269, reflects this strong performance, trading about three times higher than at the start of 2026 and 15% below its June 4 record close. The stock's P/E ratio is approximately 37 times fiscal 2028 earnings estimates, making it the most expensive of the three on a P/E basis.
Which Stock to Buy First?
All three semiconductor stocks present compelling investment opportunities as Big Tech ramps up its capital expenditures. However, Nvidia stands out as the top pick due to its attractive valuation and accelerating data center growth. Broadcom offers the fastest-growing AI business among the group, while Marvell, despite its higher valuation, shows promising growth in its data center segment and is a potential gradual buy.
While these companies are heavily reliant on a few major clients, and any slowdown in spending could impact their stock prices, the current trend suggests continued investment and growth in the AI infrastructure landscape.
