Piper Sandler Initiates Coverage on 5 AI Chip Stocks with 'Overweight' Ratings

Piper Sandler has initiated coverage on the artificial intelligence chip sector, assigning "Overweight" ratings to five key semiconductor companies. The firm identifies Nvidia, Broadcom, Advanced Micro Devices, Marvell Technology, and Arm Holdings as prime beneficiaries of what it calls a "step-change in demand" for AI computing power.

Analyst's Top Picks

In a research note, Piper Sandler analyst David O'Connor outlined the firm's bullish case for each company, establishing new price targets based on their strategic positions within the AI ecosystem.

• Nvidia (NVDA): Initiated with a $300 price target. O'Connor described Nvidia as the "outright leader in AI compute with 80% market share" and argued the stock is "among the cheapest in AI universe" based on fiscal 2028 estimates.
• Broadcom (AVGO): Started with a $460 price target. The firm highlighted its leadership in custom ASIC chips, where it holds a 75% share, and noted that current demand is double the available supply.
• Advanced Micro Devices (AMD): Assigned a $600 price target. The analyst sees AMD in an "Agentic AI Sweetspot," projecting a 65% compound annual growth rate for earnings through 2030, driven by its server CPUs and Helios GPUs.
• Marvell Technology (MRVL): Given a $270 price target. Piper Sandler pointed to a transformative $120 billion agreement with Google as a key factor and flagged the company's upcoming Oct. 6 analyst day as a potential catalyst.
• Arm Holdings (ARM): Initiated with a $320 price target. The firm cited Arm's dominance in CPU intellectual property and its expansion into custom silicon, which it said could potentially double earnings.

Surging Demand Meets Supply Constraints

According to Piper Sandler's note, the rapid adoption of agentic AI workloads has created a fundamental shift in computing needs. This surge is creating significant supply chain challenges across the industry.

The firm expects Nvidia's supply to remain constrained for the next two to three years. For Broadcom, securing additional supply is considered a key priority going forward, as the company has visibility into 12 gigawatts of demand for fiscal 2027 but currently faces demand that is twice its production capacity.

Market Context

The comprehensive launch of coverage by a major firm like Piper Sandler underscores the sustained investor focus on the hardware backbone of the artificial intelligence revolution. The analysis provides a framework for evaluating the different players in the ecosystem, from the dominant GPU provider like Nvidia to leaders in custom chips, CPU intellectual property, and emerging competitors.
