Move over, chipmakers. According to 24/7 Wall St., memory and storage maker Sandisk is outperforming every other stock in the S&P 500 so far in 2026 — and the publication frames the obvious question in its own headline: "Can Anything Stop It?"
The backdrop is the artificial intelligence boom that 24/7 Wall St. says has reshaped the stock market over the past two years. In that stretch, graphics processors — the chips that power AI training and inference — grabbed the headlines first, lifting the companies that design and build them.
But the report makes a broader point: AI infrastructure reaches far beyond those chips. Running AI at scale also requires the supporting hardware around it, and that is where a company like Sandisk, known for data storage, fits into the picture. The piece positions Sandisk's surge as evidence that investor enthusiasm is now spreading from the most famous AI names to the wider ecosystem that keeps AI systems fed with data.
The source items here are limited. Both the Bing News and Google News listings point to the same 24/7 Wall St. article, and the available text does not include specific share-price figures, percentage gains, or analyst targets. What the sources do establish is the central claim — that Sandisk leads the index in 2026 — and the framing that its rise reflects how far the AI trade has broadened.
Why it matters: when a storage company, not just a marquee chipmaker, tops the entire S&P 500, it is a signal that the market increasingly views the entire AI supply chain — not only the headline processors — as the place to bet.
