Zacks Analyst Blog Spotlights Alphabet, Microsoft, NVIDIA, Arista Networks and Vertiv in AI Infrastructure Boom
Yahoo Finance ·
On September 14, 2026, Zacks Equity Research highlighted Alphabet, Microsoft, NVIDIA, Arista Networks, and Vertiv as key players in the artificial intelligence infrastructure expansion. The global AI investment cycle has progressed from experimentation to massive infrastructure deployment, with the Bank for International Settlements estimating that the top five technology giants will invest over $1 trillion in AI during 2025-2026. Alphabet raised its 2026 capital spending outlook to $195-$205 billion, while Microsoft plans to expand its data-center footprint to about 38 gigawatts by 2032. NVIDIA reported a 117% year-over-year surge in fiscal second-quarter 2027 data center revenues alongside a trailing 12-month ROIC of 83.5%. Arista Networks posted a 37.7% revenue increase in the second quarter of 2026. As capital expenditures accelerate, market participants are increasingly focusing on whether these heavy investments translate into robust revenues, operating margins, and free cash flow conversion rather than mere capacity expansion at the expense of financial returns.
AI 시장 분석
In the second half of 2026, the AI infrastructure investment cycle of global big tech companies has moved beyond the pilot stage into a phase of massive capital expenditure. According to BIS, AI investments by the top 5 big tech companies exceeded 1 trillion dollars, with Alphabet raising its annual capital expenditure to 195 billion to 205 billion dollars. Investors must now verify investment efficiency based on revenue growth, return on invested capital (ROIC), and free cash flow (FCF) conversion rates, rather than simply looking at the scale of spending.
상승 영향
- AI — AI investments by big tech companies for 2025-2026 exceed 1 trillion dollars, generating massive infrastructure demand and directly accelerating the earnings growth of NVDA, ANET, and others.
- Semiconductors — Explosive earnings growth continues, driven by a surge in accelerated computing demand due to the advancement of AI computing power, including NVIDIA's data center revenue increasing by 117 percent year-over-year.
DYAX 전담 분석
The surge in AI infrastructure investment has triggered cascading demand for semiconductors and infrastructure, directly driving the earnings growth of related companies such as NVDA, ANET, and VRT. NVIDIA's data center revenue soared 117 percent year-over-year, while Arista Networks posted a 37.7 percent revenue increase alongside introducing a 1.6-terabit AI fabric.
The bullish scenario is that AI investment profitability is proven, leading to a sustained rise in stock prices across the related value chain, whereas the bearish scenario is that cash generation capacity deteriorates relative to astronomical capital expenditures, bringing bubble concerns to the fore. Key indicators such as ROIC and FCF conversion rates must be closely monitored going forward.
