Western Digital says 2026 HDD capacity 100% sold out, hyperscaler AI data center cloud 89% of revenue, consumer 5%, long term deals to 2028

HDD capacity from one of the world's largest manufacturers has started to run dry, according to Western Digital's CEO, as major LTAs have been signed out.

Western Digital's Consumer Share Drops to 5%, as Enterprise Demand Gobbles Up the Supply

Well, the ongoing AI supercycle has disrupted supply chains, and we have talked about DRAM and NAND before, but it appears HDDs are also in significant demand: according to WD's CEO, Irving Tan, the manufacturer's entire capacity for this year is booked out. Speaking at the Q2 earnings call, Tan revealed that the focus has been on developing products that cater to the needs of enterprise customers. Given the pace of hyperscaler buildout, it's fair to say demand for HDDs will only increase going forward.

Yeah, thanks, Erik. As we highlighted, we’re pretty much sold out for calendar 2026. We have firm POs with our top seven customers. And we’ve also established LTAs with two of them for calendar 2027 and one of them for calendar 2028. Obviously, these LTAs have a combination of volume of exabytes and price.

– WD's CEO

When we talk about major PC-first manufacturers pivoting towards AI, it is clear that demand is coming from the segment, as WD's VP of Investor Relations noted that the company's cloud revenue accounted for 89% of total revenue. In comparison, consumer revenue accounted for just 5%. When the numbers are too distant, as in WD's case, it makes sense on a business level to pivot towards enterprise demand while sidelining the client segment, as every other manufacturer is currently doing. And, in the case of Western Digital, well, this strategy is working for them.

The demand is primarily driven by the large-scale data center buildout occurring worldwide, with HDD requirements being more prevalent in US-based facilities. For those unaware, AI is nothing without data, and to store large quantities of data, CSPs use HDDs, which are the most cost-effective and efficient storage medium. The data scales to exabytes in data centers, encompassing content such as scraped web data, processed data backups, inference logs, and related data. Like AI memory, HDDs have seen massive adoption in recent years, putting suppliers under pressure.

With the AI frenzy, we have seen major PC components go into short supply, and unfortunately, this trend will persist for quite some time before we witness a meaningful recovery.
