Western Digital Corporation (NASDAQ:WDC) is one of the 10 Best Performing Growth Stocks So Far in 2026. On June 8, Mizuho raised its price target on Western Digital Corporation (NASDAQ:WDC) from $550 to $685 and maintained its Outperform rating on the stock.
The research firm raised its estimates for the company after its quarterly AI application-specific integrated circuit roadmap call. Mizuho believes there is potential for tensor processing unit demand to reach 35 million units by 2028, which would be eight times higher than the 4.3 million units in 2026.
Earlier, on June 2, Citi also raised its price target for Western Digital Corporation (NASDAQ:WDC) from $500 to $685 while keeping its Buy rating on the stock.
The research firm lifted its estimates for the hard disk drive sector, pointing to strong AI-driven demand strength and disciplined supply across the industry. Citi’s analyst told investors in a research note that this is expected to support sustainable pricing power.
As of June 8, analysts are bullish on Western Digital Corporation (NASDAQ:WDC) with a consensus Buy rating. The 12-month median price target of $545 set by analysts indicates a potential upside of 6.50% from the current stock price.
Western Digital Corporation (NASDAQ:WDC) is an American company that manufactures hard disk drives and other data storage products.

Four leading AI models discuss this article
"Upgrades embed aggressive AI-HDD assumptions that overlook WDC's product mix and enterprise SSD substitution risks."
Mizuho and Citi lifting WDC targets to $685 cite AI-driven tensor demand scaling to 35 million units by 2028 and HDD pricing power. Yet the article provides no breakdown of WDC revenue split between HDD and higher-margin NAND, nor does it address how enterprise SSD adoption in AI clusters could cap HDD upside. The 6.5% median upside to $545 already embeds much of this optimism, while the piece pivots to pitching unrelated AI names, signaling limited conviction in WDC's own trajectory.
If AI training clusters truly require 8x more storage capacity than modeled and supply discipline holds, the $685 targets could be reached within 12 months regardless of NAND exposure.
"The key risk is that AI storage demand does not scale as fast as implied, so the stock could underperform if HDD/SSD demand softens and margins compress."
Raising price targets by Mizuho and Citi signals optimism on AI-driven storage demand, but it rests on an extrapolation: TPU demand could reach 35 million by 2028 (8x 2026's 4.3 million baseline). WDC is still exposed to HDD-cycle risk and stiff flash/SSD competition, and the article glosses over margins, capital expenditure needs, customer concentration, and macro/tariff risks. Upside may be priced in, and a check on data-center capex or onshoring delays could undermine the bull case. Missing context on WDC's mix and cash flow makes the thesis fragile in a downturn.
The bullish upgrades could prove prescient if AI data-center budgets accelerate and WDC wins meaningful HDD/SSD share; with execution, the 685 target could be surpassed.
"The current price targets over-index on speculative 2028 AI demand while underestimating the volatility inherent in the cyclical storage hardware market."
The Mizuho and Citi upgrades for WDC reflect a classic cyclical pivot masked as structural AI growth. While the projected 8x increase in tensor processing unit demand by 2028 is eye-catching, it relies on WDC successfully transitioning from legacy storage to high-margin specialized hardware. At a $685 price target, the market is pricing in near-perfect execution of their AI roadmap. However, the hard disk drive sector remains notoriously capital-intensive with high fixed costs. If the industry’s 'disciplined supply' breaks—a common occurrence when incumbents chase growth—margin expansion will evaporate. Investors are currently ignoring the risk of a supply glut if NAND flash pricing softens unexpectedly.
The bullish case assumes WDC maintains pricing power, but if hyperscalers develop proprietary storage solutions to bypass traditional vendors, WDC’s margins could face secular compression rather than cyclical expansion.
"Analyst enthusiasm for WDC's AI HDD opportunity is real, but the 27% gap between new targets and consensus median reveals deep skepticism about durability of demand and pricing that the bullish narrative doesn't address."
Two major analysts raising WDC to $685 on AI-driven HDD demand looks bullish on the surface, but the median target of $545 — $140 below the new calls — signals the Street remains skeptical. Mizuho's 35M TPU unit forecast by 2028 (8x growth) is speculative; it assumes sustained AI capex without accounting for potential flash storage substitution or margin compression from supply discipline. Citi's 'pricing power' thesis contradicts the 'disciplined supply' narrative — oversupply typically erodes pricing. The article also omits WDC's exposure to legacy datacenter HDDs, which face secular decline as SSDs penetrate. The 6.5% upside from current price is modest given the volatility implied by the $140 target spread.
If Mizuho and Citi are right on TPU demand and pricing power, why hasn't the consensus moved closer to $685? The median target gap suggests either information asymmetry (unlikely for mega-cap) or that the Street sees execution risk or demand sustainability issues these two firms are underweighting.
"Custom silicon by hyperscalers threatens WDC margins more than any HDD supply glut."
Claude notes the wide target dispersion correctly signals lingering doubts, but the bigger unmentioned risk is hyperscalers accelerating custom silicon that displaces both HDD and merchant NAND. If Google and others internalize more storage designs to cut costs, WDC's supposed pricing power evaporates faster than the 2028 TPU forecasts imply. That vertical-integration path would compress margins across cycles regardless of supply discipline.
"Margin risk from hyperscaler custom silicon and NAND pricing dynamics could erase AI-driven upside for WDC even if unit demand rises."
Responding to Grok: Hyperscaler custom silicon could compress storage economics faster than TPU demand grows. But even if hyperscalers go private, WDC still earns from NAND and enterprise-scale HDD/SSDs used outside those silos, and could win via diversified firmware/licensing or services. My concern is not demand but margin risk under accelerated capex; if NAND pricing softens or supply is disciplined, the AI upside may never translate into durable margin expansion.
"The rapid decline in NAND costs will trigger an SSD-for-HDD substitution cycle that destroys WDC's legacy margin base before AI demand can compensate."
Grok and ChatGPT are over-indexing on hyperscaler vertical integration. The real risk is the 'HDD-to-SSD' crossover point. As NAND costs per TB drop, enterprise SSDs will cannibalize high-capacity HDDs faster than AI demand can backfill the volume. WDC’s reliance on legacy HDD margins makes them uniquely vulnerable to this substitution. If the 'pricing power' thesis relies on HDD scarcity, it ignores the inevitable commoditization of NAND that will render those legacy assets obsolete.
"The bull case hinges on whether AI storage demand growth exceeds SSD substitution speed—a testable metric the article never provides."
Gemini's HDD-to-SSD crossover risk is the sharpest point here, but it conflates two timelines. NAND cost curves have flattened since 2020; enterprise SSD adoption is already accelerating, yet WDC's HDD revenue hasn't collapsed—it's stabilized. The real question: does AI's 8x storage capacity demand (if real) outpace SSD substitution velocity? If yes, HDD scarcity props margins. If no, Gemini wins. Nobody's quantified the crossover rate.
