Nvidia Corp. (NVDA) trades at 23 times forward earnings. SanDisk Corp. (SNDK) commands 28 times. The GPU monopoly with a 75% gross margin and a decade of software lock-in is cheaper on next year's numbers than the NAND flash supplier feeding its racks — a divergence Jim Cramer called "insulting" on his July 9 Mad Money broadcast.
"Some of the commodity chip companies like SanDisk now have price earnings multiples that are higher on next year's earnings than Nvidia," Cramer said. "SanDisk is a commodity chip maker. Nvidia is the most proprietary chip company in the history of the world."
The math backs his frustration. Nvidia's fiscal first quarter delivered $81.61 billion in revenue, up 85% from a year earlier, with its Data Center segment alone contributing $75.25 billion — a 92% increase. Networking revenue, spanning InfiniBand, NVLink and Spectrum-X, grew 199% year over year. Non-GAAP gross margin held at 75%, and the board authorized an $80 billion buyback. SanDisk's fiscal third quarter was a different kind of shock: revenue more than tripled to $5.95 billion, beating its own guidance range of $4.4 billion to $4.8 billion. Gross margin exploded to 78.4% from 22.5% a year earlier, and Data Center revenue surged 645%. Non-GAAP earnings per share of $23.41 beat the analyst consensus of $14.36 by more than 60%.
The valuation gap reflects two fundamentally different business models. Nvidia sells software-wrapped compute with a CUDA ecosystem that locks in hyperscaler customers — Amazon, Microsoft, Alphabet and Meta are on allocation, with $119 billion in supply commitments on the books. Its operating margin of 65.6% reflects pricing power that comes from owning the full stack, from silicon to networking to the software layer. SanDisk sells NAND flash memory, a commodity whose pricing has swung by 50% or more in a single quarter across three decades of boom-bust cycles. The company's New Business Model contracts — multi-year supply agreements with fixed or range-bound pricing and $42 billion in remaining performance obligations — reduce spot-market exposure but cover only about one-third of fiscal 2027 production. The remaining two-thirds still faces market pricing.
Why the market is pricing this way
SanDisk shares have surged 707% year to date to $1,915.92, making it the best-performing stock in the S&P 500 by a wide margin. The rally reflects a severe NAND shortage driven by AI data center demand that emerged faster than the industry's production capacity could respond. Building a new NAND fabrication facility costs $15 billion to $20 billion and requires two to three years from investment decision to volume production. Meanwhile, Samsung and SK Hynix have been diverting wafer capacity away from NAND toward High Bandwidth Memory, which commands higher margins for AI accelerators. The result: NAND contract prices rose 55% to 60% quarter over quarter in the first three months of 2026 and accelerated to 70% to 75% in the second quarter, per TrendForce data.
Nvidia shares are up 13% year to date to $210.96, a more modest gain that reflects the law of large numbers — the company is on pace to generate more than $350 billion in annual revenue — and growing investor debate about whether the AI infrastructure buildout can sustain its current trajectory. The analyst consensus target of $301.62 implies roughly 43% upside from current levels, according to data compiled by Bloomberg.
The risk that changes the math
SanDisk's scarcity premium faces its first real test. SK Hynix, the world's dominant producer of High Bandwidth Memory and a major NAND competitor, began trading on Nasdaq on July 10 under the ticker SKHY in what is expected to become the largest foreign-company ADR listing in US market history, raising approximately $28 billion to $29 billion. For the past 16 months, US investors seeking pure-play AI memory exposure had essentially two choices: Micron Technology for DRAM and SanDisk for NAND. SK Hynix offers both, plus HBM leadership, at what multiple analysts describe as a significantly lower price-to-earnings multiple.
SanDisk reports fiscal fourth-quarter results on Aug. 13. The company guided revenue of $7.75 billion to $8.25 billion with gross margin of 79% to 81% and earnings per share of $30 to $33 — all well above what analysts had modeled before the print. The specific catalysts to watch are forward guidance on NAND average selling price trends, the production ramp of the QLC Stargate product (a quad-level cell drive that stores 30% more data per chip at a lower cost per bit), and any additional New Business Model contract signings.
For investors weighing the two, the choice comes down to what they are paying for. Nvidia at 23 times forward earnings offers a realized cash-flow machine with a proprietary moat and hyperscaler customers who cannot easily switch. SanDisk at 28 times forward earnings offers a cyclical commodity business that has temporarily transformed into a structural growth story through an unprecedented supply shortage and a new contracting model. If NAND pricing softens even modestly in 2027, that 78.4% gross margin compresses fast, and the premium multiple has nowhere to hide.
