This Tech Stock Minted a New Wave of Millionaires in Just 1 Year | $25k to $1.13M

So far into 2026, SanDisk (NASDAQ:SNDK | SNDK Price Prediction) has left most other AI companies looking like corporate afterthoughts. The AI infrastructure cycle has been incredibly rewarding for this company and the rewards keep coming. Those who bought even just one year ago are laughing their way to the bank.

The datacenter segment went from rounding error to headline number, posting $1.47 billion in Q3 FY26 revenue, up 645% year over year. Non-GAAP gross margin expanded from 22.5% to 78.4% in twelve months. CEO David Goeckeler called it “a fundamental inflection point”.

Your $25k would have turned into something life-changing

SanDisk has only traded as SNDK since the February 2025 spin, so there is no five-year or ten-year history. Just the one window.

But let’s just look at what happened inside that window. If you invested $25,000 in February 2025, you would have $1.13 million today. $25k is almost trivial for most retirees and people with sensible portfolios, and the returns would certainly make you consider cashing out and retiring.

There were dozens of people who invested more than that when SNDK stock came online and are now fresh millionaires.

A recent Reddit post titled “locked in 228k sndk gains today” hit 658 upvotes. Another person posted on Reddit a screenshot of their portfolio, where they made $333k off of SNDK stock in just one day. Using options, their total return was at $843k, and they said they “bought 1,500 shares two weeks ago… at $1,000/share”. They said they were holding “until $5,000”.

What actually drove the run

Hyperscaler NAND demand exploded while supply stayed disciplined. Goeckeler told investors “demand for our NAND products continued to outpace our supply, a dynamic we expect to persist through the end of calendar year ’26 and beyond”. Fabs are running at 100% utilization. SanDisk signed five multi-year customer commitments under its New Business Model, retired $650 million in debt, and reached zero long-term debt. Q4 FY26 guidance calls for $7.75 billion to $8.25 billion in revenue and $30 to $33 in non-GAAP EPS.

Would I buy SNDK near the highs?

I would put more money into SanDisk today if I believed the memory shortage genuinely runs through 2028 and hyperscaler storage budgets keep compounding. The forward multiple sits at just 9x, which is not stretched for a business whose datacenter line grew triple digits. The consensus price target is below $1,300, but this is mostly because the stock is moving up so fast that analysts are having a hard time keeping up.

Individual investors are looking at far more ambitious targets, through $2k, and sometimes even $5k, such as the Redditor I mentioned earlier.

I would avoid it if I think memory is still memory. NAND has been a boom-bust commodity for three decades, and a run of this magnitude in twelve months tends to pull years of fundamentals forward. Consumer segment revenue already declined 10% sequentially in Q3 FY26. One soft hyperscaler order book changes the entire story.

Anyone holding from the $40s is sitting on a once-in-a-decade outcome. Anyone arriving now is buying into the cyclical reality this business has always had, because the next leg looks nothing like the last one. I would not use risky options here unless you really know what you were doing. The easy money has mostly been made, but you can still make multibagger returns if this stock keeps rallying higher and higher. For now, it seems like this is the case due to the unceasing hyperscaler spending on AI hardware.

But before you buy, I would warn against buying just because others have made money on the stock. This is a stock that is riding entirely on AI spending, and no one has a crystal ball to predict when the spending will pull back.
