Palantir shares fell even as the company reported strong growth, while SanDisk surged on the back of accelerating demand and profitability in data-center memory. Investors appeared to weigh the durability of Palantir’s business model against mounting concerns about how rapidly advancing agentic artificial intelligence could change the economics of software-as-a-service.
The divergence comes as both companies are closely watched through the lens of AI. Palantir provides data unification and analytics for government and commercial clients, whereas SanDisk makes NAND flash used in data-center storage and benefits from a tighter memory market.
Key takeaways
- Palantir shares dropped despite robust reported results as investor focus shifted to whether AI agents could erode parts of the value proposition for software platforms.
- SanDisk shares rose after earnings and further strength tied to surging data-center demand and pricing power for NAND flash.
- AI-agent concerns weighed on Palantir, with market participants questioning how durable the company’s moat remains as AI automation spreads.
- SanDisk benefited from market structure, including high demand and supply constraints that support higher memory pricing and visibility.
- Valuation is a key implication: Palantir trades at a far higher valuation multiple, leaving less room for uncertainty, while SanDisk’s valuation has cooled from its post-earnings peak.
What drove the move in Palantir?
Palantir has built a reputation around a proprietary AI platform designed to unify information from different data silos for government and commercial customers, alongside data analysis and decision support. The company also emphasizes deployment support, including embedding its platform within client organizations and providing trained specialists to help integrate the technology.
Those elements have helped Palantir accumulate long-term contracts and maintain a defensible position, according to the company’s operating approach. In the first quarter, Palantir reported revenue growth of 85% year over year, with a 104% increase in U.S. commercial businesses. Total contract value increased 61%, and adjusted operating margin was 60%.
However, Wall Street’s reaction reflected a separate set of concerns. The report said Palantir was among the most visible casualties of a broader market rotation away from SaaS names. The core worry is that AI agents may be able to handle work traditionally performed by SaaS platforms, which could reduce differentiation or pricing power over time.
Investors also appeared to focus on valuation risk. The article said Palantir’s price-to-earnings multiple rose above 600 at one point last year, making the stock more sensitive to any sign that growth might not be sustained at the level implied by such expectations.
Why SanDisk stock was stronger
SanDisk operates in a different segment of the AI supply chain. The company produces NAND flash memory, a critical component for data-center storage. The article attributed SanDisk’s strength to the combination of demand and supply constraints across the memory market, which has supported pricing power.
In addition, SanDisk changed its business model to include long-term contracts for large customers, a shift designed to bring more stability to a market that has historically been cyclical.
In its fiscal 2026 third quarter, which ended April 3, SanDisk reported revenue up 251% year over year and 97% sequentially. Growth was reported across segments, but the data-center segment drove much of the quarter’s results, with data-center revenue rising 233% sequentially.
The earnings update also highlighted profitability. The article said operating income increased from $2 million in the prior-year period to $4.2 billion in the fiscal third quarter, helped by the intensifying memory shortage and higher product pricing.
Market reaction and what it suggests
The article said SanDisk shares surged following its May 7 earnings report, then later pulled back in late June after reaching a valuation level around 80 times earnings. It added that SanDisk’s valuation subsequently fell to roughly 47 times earnings as the stock gave back most of its post-earnings gains.
By contrast, the article said Palantir continued to trade at a much higher valuation multiple—about 149 times trailing-12-month earnings—leaving the stock more exposed to questions about long-term competitiveness in an environment where AI agents may automate tasks previously associated with software platforms.
For investors, the split underscores how markets can separate fundamentals from narrative. Even with strong reported growth, Palantir’s shares faced a skeptical interpretation centered on whether AI-driven automation could reduce the durability of its platform advantage. SanDisk, meanwhile, was rewarded for supply-chain fundamentals: tight memory conditions, pricing leverage, and a move toward steadier customer commitments.
Bigger picture: what to watch next
Investors will likely monitor whether Palantir can sustain growth while maintaining differentiation as agentic AI adoption accelerates. For SanDisk, attention is likely to turn to whether continued demand and pricing power persist into its fiscal fourth-quarter results on Aug. 5. With AI reshaping both software workflows and the infrastructure that supports them, the next catalysts for both companies may hinge as much on guidance and forward-looking indicators as on the reported quarter itself.
