<div id="readability-page-1">If it wasn't clear before, there's no denying it now: we're in the middle of an AI memory chip gold rush. Two of the biggest beneficiaries so far are Micron (NASDAQ:MU) and SanDisk (NASDAQ:SNDK), both of which have seen revenue surge, profitability expand, and their stocks shoot to the heavens as demand for AI infrastructure continues accelerating.<h3>Claim 55% Off TipRanks</h3>Trade SNDK with leverage Micron blew expectations out of the water with its latest fiscal Q2 2026 report, delivering revenue of $23.9 billion – up 75% sequentially and 196% year-over-year. Not only did that mark the largest sequential quarterly revenue increase in company history (+$10.2 billion), but the company's guidance of $33.5 billion for the current quarter came in more than $10 billion above Wall Street's expectations. And it's not just about revenue growth. As Micron's high-bandwidth memory (HBM) technology becomes increasingly essential for AI workloads, demand has far outpaced supply. That imbalance has handed the company enormous pricing power, with Micron now expecting a gross margin of 81% for fiscal Q3 2026. In response, MU shares have soared 777% over the past twelve months. As remarkable as that run has been, it still trails the staggering 4,162% rally posted by SNDK over the same time period.</div>

The global semiconductor sector experienced a strong surge, with the chip index jumping over 4%, outperforming the broader market and hitting a new all-time high! AMD, the computing power giant, saw its data center business grow by 57% in the first quarter and its second-quarter guidance significantly exceeded expectations, leading to a post-market surge of over 10%. Intel's stock price rose nearly 13% in a single day, boosted by rumors of Apple's contract manufacturing talks. Micron Technology and SanDisk, two major memory manufacturers, both hit new all-time highs overnight, driven by strong AI demand and expectations of locked-in long-term contracts. The "supercycle" in the semiconductor industry chain has not only not peaked, but is accelerating in a deeper and broader dimension.
