On September 9, Western Digital rose 3.21% in regular trading, trading at $482.55 per share, with turnover of $12.96 billion. The rally was driven by OpenAI's release of its next-generation large language model GPT-6 Astra, which sparked a broad-based surge across the storage sector.

GPT-6 Astra introduces the ability to directly operate computers and software on behalf of users, handling complex tasks such as programming and 3D modeling. The market expects this capability to dramatically increase demand for storage chips and flash memory resources, benefiting companies like Western Digital. The broader storage sector reflected this optimism, with Seagate Technology up 6.51%, SanDisk up 2.52%, and SK Hynix rallying over 6% during the session.

Fundamental tailwinds further supported the move. Global DRAM market revenue reached $147.024 billion in the second quarter, surging 55.9% quarter-over-quarter to a record high, underpinned by robust AI server demand. Additionally, multiple Western Digital executives recently made concentrated insider purchases, reinforcing market confidence in the company's outlook.
