AI demand drives rating revision

S&P Global lifted its outlook on Western Digital from stable to positive, pointing to the surge in AI-related demand for data storage infrastructure. The agency's move reflects expectations that AI workloads — from training large language models (LLM) to data center operations — are boosting orders for the company's hard drive and storage products.

The upgrade does not constitute an immediate rating change but indicates that a future increase is more likely if the company's performance continues to improve in line with the agency's expectations.

Implications for the storage market

Western Digital is a major supplier of hard disk drives used in data centers worldwide. The company's Korea-linked ecosystem includes partnerships across the memory and semiconductor supply chain, where suppliers such as Samsung Electronics and SK hynix monitor storage demand as a proxy for broader AI infrastructure spending.

The positive outlook adds to signals that AI investment is flowing beyond GPUs and HBM into the wider hardware ecosystem, including storage components.

The claim that S&P Global raised its outlook on Western Digital to 'positive' on surging AI demand is True.
