Wall Street rewrites its own narrative in a quiet rhythm, and last Friday’s Nasdaq announcement was one of those occasions that seemed minor on paper but loud on the inside. On Monday, April 20, before the opening bell, SanDisk, the storage chip company that most people still associate with the SD cards hidden inside outdated cameras, will formally join the Nasdaq 100. Jira and Confluence are powered by the Australian-born collaboration software company Atlassian. More about 2026 can be inferred from this swap than from any analyst note.
Here, the mechanics are fairly straightforward. Since over 200 investment products with over $600 billion in assets track the Nasdaq 100, passive funds will need to purchase SNDK in order to match the new benchmark. Shares were already rising 6% to 7% in Monday trading, hovering around $905 to $915 after Friday’s close of $851.77. This alone tends to create what traders refer to as an index-inclusion rally. However, the mechanical purchasing isn’t the true story. That’s the reason this swap is taking place at all.

It has been interesting to observe how SanDisk has changed. It was hardly noticed by most institutions a year ago. The company’s stock has increased 2,439% in the last 12 months, its market capitalization is currently close to $125.7 billion, and CEO David Goeckeler has been publicly redefining the company as an AI infrastructure play rather than a consumer storage brand. He described the data center push as the single biggest structural shift in the NAND flash industry when he spoke at the Morgan Stanley Technology, Media, and Telecom Conference back in March. He predicted that by 2026, data center customers would overtake PC and smartphone manufacturers as the biggest NAND buyers. It used to take ten years to make that kind of change. It appears that SanDisk completed the task in about eighteen months.
The narrative is supported by the numbers, which is important because stories without numbers often fall apart. According to all accounts, hyperscalers and AI infrastructure builders racing to increase storage capacity drove data center revenue’s 64% sequential growth in the most recent quarter. $3.03 billion was the total revenue for the quarter.

Asiya Merchant, a Citi analyst, increased her price target to $980. Mizuho increased to $1,000 from $710. The most optimistic of the group, Bernstein, raised its goal to $1,250. Even the optimists seem to be struggling to keep up with these numbers.
The removal of Atlassian has a subtle sting of its own. The business isn’t even close to being broken. Due to enterprise software resilience and customers integrating AI tools into their workflows, it recently increased its fiscal 2026 revenue growth forecast. However, the market’s attitude toward SaaS has cooled. According to Reuters, investors are agitated due to new worries that Anthropic’s more recent models might upend conventional software pricing. TEAM was caught in the downturn as software stocks generally declined. Automatic passive inflows are lost if the index seat is lost. It is not a fundamental penalty; rather, it is a style penalty. The company continues to operate. There simply isn’t the patience for valuation.
It’s difficult to ignore the pattern. Slowly but surely, the Nasdaq 100 is evolving from a software-as-a-service index to one based on AI infrastructure. Picks and shovels, networking, storage, and semiconductors. It’s genuinely unclear if that will continue during the next cycle. For the time being, however, SanDisk has its moment and the index has a business that is appropriate for the time period it is attempting to depict.
