Broadcom Vs. Micron: Which Semiconductor Stock Wins the AI Sell-Off?

• Broadcom's custom AI silicon offers a more durable moat than Micron's cyclical memory business • Broadcom AI semiconductor revenue rose 143% YoY to $10.8B, guided to $16B next quarter • Micron's cheap P/E masks cyclical memory risk and rising Chinese competition The AI sell-off has investors weighing two different ways to play the boom: Broadcom's custom AI silicon versus Micron's memory exposure. Broadcom (AVGO) has fallen over 35% from its peak, while Micron (MU) trades at a seemingly cheap earnings multiple — but cheaper isn't necessarily safer. Broadcom's edge comes from designing custom AI accelerators and networking chips with major tech customers, a harder-to-replicate business than standard chip cycles. AI semiconductor revenue hit $10.8 billion in fiscal Q2 2026, up 143% year over year, with CEO Hock Tan guiding to $16 billion next quarter. Still, Tan's comparison of AI investment enthusiasm to a casino has fueled concerns about speculative spending. Micron's high-bandwidth memory is essential to AI accelerators, and fiscal 2026 revenue reached $133.19 billion versus $37.38 billion the prior year. At an 11.82 P/E and forward multiple of 5, Micron looks cheap — but memory is cyclical, and today's tight supply could normalize. Chinese competitor ChangXin Memory Technologies also threatens Micron's position. Broadcom looks like the stronger long-term business; Micron could offer more upside if memory pricing stays strong. Upcoming earnings will test whether AI spending holds up for both.
