Micron, SanDisk stocks rise as investors boost AI spending confidence Micron Technology and SanDisk shares climbed 7-9% in July 2026 trading sessions, recovering after a correction, as renewed investor confidence in AI infrastructure spending and analyst upgrades from Bank of America restored bullish sentiment. Micron announced plans to raise its US investment commitment to $250 billion through 2035, while SanDisk, which spun off from Western Digital in February 2025, has gained over 570% year-to-date. Via purepng.com Micron, SanDisk stocks rise as investors boost AI spending confidence Memory chip stocks rebound sharply in July 2026 as AI infrastructure demand and analyst upgrades restore bullish sentiment after a rough patch. The memory chip trade is back on. Micron Technology and SanDisk shares climbed 7-9% in recent July 2026 trading sessions, recovering ground after a bruising correction that had left both stocks well below their 2026 peaks. The catalyst: renewed investor confidence that AI infrastructure spending isn’t slowing down anytime soon, backed by a round of analyst upgrades and Micron’s eye-catching commitment to dramatically expand its US manufacturing footprint. A year of extremes To understand why a 7-9% bounce matters, consider where these stocks have been in 2026. SanDisk, which only began trading independently on Nasdaq in February 2025 after completing its spin-off from Western Digital, has gained more than 570% year-to-date as of late July 2026. Micron’s run was less stratospheric but still substantial, with triple-digit percentage returns earlier in the year before volatility set in. Both stocks then hit turbulence, with Micron pulling back roughly 25% from its 2026 highs and SanDisk facing steeper declines from its peak. Mixed results from peers like South Korea’s SK Hynix added to the anxiety. SK Hynix’s performance matters here because the global memory market is effectively a three-legged stool: Micron, SK Hynix, and Samsung. When one of those legs wobbles, investors tend to reassess the whole structure. Why AI memory is the center of gravity Micron specializes in DRAM, the high-speed memory that sits close to a processor and handles data in real time. SanDisk’s focus sits more in NAND flash storage and enterprise solid-state drives, which store the vast datasets AI systems need to learn from. Bank of America was among the institutions that issued upgrades contributing to the July rebound. The upgrades landed at a useful moment, and a 7-9% single-session bounce suggests the pent-up demand for entry points was real. Micron’s $250 billion bet The bigger strategic story running alongside the stock price action is Micron’s announcement of plans to raise its US investment commitment to $250 billion through 2035. The timing connects directly to two converging pressures. First, AI model builders want memory produced closer to home, partly for supply chain security and partly because government incentive programs have made domestic production more economically attractive. Second, Micron faces genuine competitive pressure from Samsung and SK Hynix, both of which benefit from significant South Korean government support. Micron’s commitment also arrives in a policy environment shaped by the Chips and Science Act, passed in 2022, which created a framework of grants and tax incentives designed to pull exactly this kind of investment onto American soil. For SanDisk, having only recently established its identity as an independent company after separating from Western Digital in February 2025, the 570% year-to-date gain suggests the market has formed a fairly optimistic view of its prospects. SanDisk’s focus on high-performance enterprise SSDs positions it squarely in the data center build-out narrative, and the spin-off gave SanDisk the freedom to pursue that focus without being bundled into a broader hard-drive and consumer-storage business with very different growth dynamics. What investors are watching next The near-term variables worth tracking include whether hyperscaler capital expenditure guidance holds up through the rest of 2026, how SK Hynix’s next earnings report lands relative to expectations, and whether Micron’s own upcoming results confirm that AI memory demand is translating into revenue at the pace the stock price implies. Bank of America’s upgrades and Micron’s $250 billion capital commitment have given the bulls something to work with heading into August, but both Micron and SanDisk are priced for a prolonged, steep upward demand curve in AI memory—valuations that become uncomfortable quickly if AI spending growth decelerates from its current pace.
