Sandisk (NASDAQ: SNDK) has emerged as one of the standout performers on Wall Street in 2026, with its stock surging more than 250% year-to-date.
By press time, SNDK was trading at $851, marking a roughly 2,500% increase over the past year.
The company’s rapid ascent follows its spin-off from Western Digital in early 2025, positioning it as a pure-play NAND storage leader at the center of the artificial intelligence infrastructure boom.
The rally has been driven by strong demand for high-performance NAND flash and enterprise solid-state drives used in hyperscale AI data centers.
A widening supply-demand imbalance has supported pricing, with global NAND supply growth estimated at 15% to 17% this year while data-center demand has surged more than 60% sequentially in recent quarters.
This strength is reflected in Sandisk’s fiscal Q2 2026 results, with revenue rising 61% year over year to $3.03 billion, alongside expanding margins and strong guidance.
Momentum is also supported by the company’s upcoming inclusion in the Nasdaq-100 Index on April 20, 2026, replacing Atlassian.
The move is expected to drive automatic buying from index-tracking funds such as Invesco QQQ Trust, which manages hundreds of billions in assets and typically provides short-term price support through passive inflows and increased institutional visibility.

Against this backdrop, Finbold turned to OpenAI’s ChatGPT for insights on where SNDK stock could trade by the end of 2026.
The forecasts factor in index inclusion effects, the ongoing memory supercycle, elevated valuations after a multi-thousand-percent rally, and typical consolidation patterns following parabolic moves.
In the base-case scenario, ChatGPT projects Sandisk shares at $900 to $1,200 by year-end 2026, implying upside of about 5% to 40% from current levels. This assumes continued earnings growth driven by AI demand, with limited valuation expansion as the stock matures. The Nasdaq-100 inclusion is viewed as a temporary catalyst, with a 60% probability assigned to this outcome.
A more bullish case sees the stock reaching $1,400 to $1,800 if AI demand accelerates, NAND pricing remains tight into late 2026, and institutional capital continues rotating into AI infrastructure. This scenario carries a 25% probability.
On the downside, ChatGPT outlined a bear-case range of $500 to $700, reflecting risks such as a post-inclusion pullback, easing memory conditions, or a broader rotation away from high-valuation tech stocks. Even then, a drop toward $600 would leave the stock structurally higher over the long term, with a 15% probability.
Furthermore, the analysis suggested Nasdaq-100 inclusion is typically a one-off liquidity event, often priced in early and followed by higher volatility.
As a result, Sandisk’s long-term performance is expected to depend more on earnings growth tied to AI infrastructure demand and memory pricing than on index membership.
