Marvell Technology (MRVL) Stock Jumps 5.7% as Micron’s Blowout Signals AI Chip Supply Shortage

Shares of Marvell Technology (MRVL) surged 5.7% on May 27, 2026, after Micron Technology’s strong results signaled that demand for artificial intelligence chips remains structurally undersupplied, a bullish signal for equipment makers and foundries that build capacity. Micron’s plan to spend more than $50 billion on capacity over the next five years implies billions of dollars in equipment orders, benefiting the entire semiconductor supply chain. Marvell, a networking chip designer, has rallied 134% this year to a new 52-week high of $209.43. The move follows recent analyst upgrades ahead of Marvell’s earnings report. Citigroup, Oppenheimer, Wells Fargo and Melius Research cited accelerating AI infrastructure demand and strong sales of Marvell’s custom Trainium chips to Amazon. Oppenheimer forecast custom chip sales could reach $2 billion this year.
