SanDisk's 644% Run Meets a $2,400 Bet on AI Storage
Rosenblatt Securities initiated coverage of SanDisk (SNDK) with a Buy rating and a $2,400 price target on Sept. 22. That call came after SanDisk shares had risen 644% year-to-date in 2026, according to CNBC.
A price target is the analyst's estimate of where the stock could trade. Rosenblatt's case is that AI workloads are repricing NAND flash, the chips used to store large amounts of data, from plain commodity storage into critical AI infrastructure, according to 24/7 Wall St.. The $2,400 target was reported alongside the initiation that same day, according to Invezz. The thesis ties the valuation to AI workloads and storage intensity, meaning how much data AI systems need to save and read.
SanDisk had already been named as a beneficiary of AI-driven demand for memory and storage products in August, according to CNBC. On Jan. 22, Bloomberg reported memory and storage stocks were the market's hottest trade as AI redefined the memory market.
April gives a marker for the scale of the advance. On April 27, CNBC reported SanDisk rose 8.1% on Monday and was up over 3,000% in the past year, with market capitalization, the total value of all its shares, above $157 billion, according to CNBC.
The broader context here is the valuation question behind the infrastructure label. A commodity framework prices NAND on cycle timing, factory use and mean reversion, the tendency for high prices and profits to fall back toward average. An infrastructure framework prices it on duration, data throughput and system-level need. That shift matters for multiples, the number investors pay for each dollar of earnings. It also matters for how investors judge downside. It requires confidence not only in sales volumes but in lasting pricing power. For a trading desk, that distinction shapes holding period, tolerance for drawdowns and how earnings revisions are weighed against a change in the multiple.
In my view, starting coverage after a 644% year-to-date run reframes the target. It is not a call for prices to snap back. It is a call that the earlier repricing was incomplete. For professionals, the test is whether end-demand and contract structures support that extension, or whether spot pricing and inventory behavior still drive the cycle. Coverage initiations late in a sharp move often work as framework notes. They tell large holders how to justify staying invested. Rosenblatt has taken a position. The market had already placed a large bet.
Looking at what this means for risk, the setup is concentrated. Momentum is extreme. Expectations are elevated. The thesis depends on AI workloads sustaining storage intensity at scale. If that holds, investors can justify looking through normal cyclical swings. If it falters, the distance back to a commodity multiple is wide. That does not make the $2,400 target right or wrong. It makes the path dependent on earnings revisions, not rerating alone. Discipline around position sizing and revision risk counts more than the target itself.
