I'm LongbridgeAI, I can summarize articles.Bank of America identified Nvidia, Intel, Marvell Technology, Micron Technology, and Lam Research as top AI chip stock picks for Q4, citing strong AI infrastructure spending. BofA raised its 2030 AI data center market forecast to $2.2 trillion, driven by AI agents and cloud provider capital expenditure growth. The firm highlighted specific catalysts for each stock, including Nvidia's accelerator dominance, Intel's server CPU demand, Micron's buybacks, Marvell's custom processors, and Lam Research's equipment exposure. TipRanks data shows Micron with the highest analyst upside potential at 47.12%.
The fourth quarter is about to begin, and AI spending remains a major driver for chip stocks. Bank of America named Nvidia (NVDA), Intel (INTC), Marvell Technology (MRVL), Micron Technology (MU), and Lam Research (LRCX) as its top semiconductor picks for Q4.
BofA also raised its forecast for the AI data center systems market to $2.2 trillion by 2030, up from $1.8 trillion. The firm expects spending to remain strong as AI agents become more common.
Historical trends also support a positive outlook for chip stocks heading into Q4. BofA found that Q4 and Q1 have historically been the best periods to own chip stocks, with median outperformance of 300 to 500 basis points versus the S&P 500 from 2010 through 2025.
Why Is BofA Bullish on AI Chip Stocks in Q4?
BofA expects AI infrastructure spending to stay strong as companies build more computing capacity. The firm sees AI agents as an important next step in the AI cycle.
AI agents can handle multi-step tasks instead of simply responding to one request. This can raise computing needs across data centers and support demand for chips, memory, and related equipment.
Competition among AI labs could also keep spending elevated. Even a slower pace of AI model development may not mean lower infrastructure demand. BofA said additional safety measures for advanced AI models could instead increase computing needs.
The spending outlook is already large. BofA expects combined capital spending by major U.S. and Chinese cloud providers to reach about $1 trillion in 2026 and $1.4 trillion in 2027. It sees that figure rising to $2 trillion to $3 trillion by 2030.
Why Does BofA Like These 5 AI Chip Stocks?
The five stocks offer different ways to benefit from continued investment in AI infrastructure. BofA sees a specific catalyst for each of its five picks as Q4 begins.
Nvidia stands to benefit from its strong position in AI accelerators. BofA pointed to enhanced buybacks and multiple GTC events as potential catalysts. The firm expects Nvidia to retain at least 70% of the AI accelerator market over time. NVDA stock is up 25.44% year-to-date.
Intel could benefit from stronger demand for server CPUs as AI workloads become more complex. BofA also expects a potential foundry customer win to support the stock. The firm sees the server CPU market growing from about $61 billion in 2026 to $210 billion by 2030. INTC stock has gained 223.39% year-to-date.
Micron could benefit from continued demand for memory used in AI data centers. BofA sees the company's planned share buybacks starting December 9 as a potential Q4 catalyst. Micron also recently reported strong fiscal Q4 results and gave above-consensus guidance for fiscal Q1. MU stock is up 276.61% year-to-date.
Marvell has an important near-term event on October 6. Its Analyst Day will give investors more insight into the ramp of its custom XPU processors. BofA sees this business as another way to benefit from rising AI infrastructure demand. MRVL stock has gained 220.42% so far in 2026.
Lam Research gives investors exposure to the equipment side of the chip cycle. BofA sees room for the company to gain share across memory and logic as semiconductor manufacturers expand capacity. The firm expects wafer-fab equipment spending to rise from $156 billion in 2026 to $360 billion by 2030. LRCX stock is already up 103% year-to-date.
Which Is the Best AI Chip Stock, According to Analysts?
TipRanks' Stock Comparison Tool shows Micron with the highest analyst upside potential at 47.12%. Nvidia follows with 38.63% upside, while Lam Research and Marvell offer 14.56% and 9.92%, respectively.
Meanwhile, Intel's average analyst price target of $114.38 implies 4.14% downside, and analysts have a Hold consensus. The other four stocks have Strong Buy ratings.
