Semiconductor rally accelerates amid AI infrastructure bets

Semiconductor stocks have become the defining trade of May 2026, with shares of Micron, SanDisk, AMD, Intel, and Qualcomm surging on the back of sustained enthusiasm for artificial intelligence infrastructure buildout. Retail investors, who largely sat out April's record chip advance, have now jumped in aggressively, pushing valuations to levels that prompt even bullish analysts to question sustainability. The Samsung-Hynix labor deal and new 3D NAND technology announcements from Kioxia have reinforced the narrative that memory supply constraints will persist, justifying premium valuations for producers.

Multiple sources highlight the extreme nature of the current move. Shares of Micron have climbed to levels where they trade at higher multiples than most mega-cap names outside Tesla.

Memory chip stocks like DRAM are trading near $53, with bullish targets toward $60.

The narrative hinges on several structural drivers: Korea's SK Hynix partnership with SanDisk and HBF memory deals; the multi-year backlog for AI burn-in capacity at firms like Aehr Test Systems (41 million orders); and Nvidia's supply-chain lock-up strategy through partnerships with optical and photonics names like Littelfuse, Coherent, and Broadcom. If AI capex slows or data centers prove oversupplied, the rally risks a 20-60% correction.
