We recently published a list of 20 Best Data Center Stocks to Buy According to Billionaires. In this article, we are going to take a look at where Western Digital Corp. (NASDAQ:WDC) stands against other best data center stocks to buy according to billionaires.

Data centers have become the foundation of the digital economy, facilitating the storage, processing, and distribution of vast amounts of data that drive industries worldwide. According to McKinsey & Company, the global data center market is set for significant expansion through 2030, fueled by enterprise digital transformation and hyperscale cloud growth. Their analysis projects that global demand for data center capacity could grow annually by 19% to 22% between 2023 and 2030, ultimately reaching between 171 and 219 gigawatts (GW) of annual capacity (compared to 60 GW currently). As per McKinsey, at least double the data center capacity built since 2000 would have to be built in less than one-fourth of the time, to avoid a capacity shortfall.

At the start of the year, investor sentiment toward data centers soared following the high-profile announcement of Project Stargate, a landmark $500 billion initiative aimed at revolutionizing data center infrastructure. However, enthusiasm has tempered later in the first quarter as discussions have emerged over potential repealing of the CHIPS Act. This legislation was originally designed to strengthen U.S. semiconductor manufacturing and reduce reliance on foreign suppliers, and it has played a key role in reshaping domestic production capabilities. The ongoing debate over its future has introduced uncertainty into the market, influencing investor outlooks.

Amid these discussions, a February 2025 PwC report underscores the strategic importance of expanding data center infrastructure—not only for technological advancement but also for geopolitical stability. Nations are increasingly wary of relying on critical infrastructure in high-risk regions. Geopolitical tensions and trade restrictions continue to expose vulnerabilities in global supply chains, prompting companies to implement contingency strategies. PwC further adds that expanding into new markets introduces additional challenges, including strict security and data privacy regulations, particularly in non-U.S. jurisdictions with stringent compliance frameworks. As a result, data center operators must carefully balance regulatory requirements, infrastructure investments, and market demand while navigating an evolving global landscape.

In a March 10 interview with CNBC, Charlie Sanchez, President of Infrastructure Advisory at Black & Veatch, discussed the ongoing surge in AI-driven infrastructure investment, particularly within data centers. He emphasized that despite trade tariffs, the commitment to data center development remains robust, both in the U.S. and globally. Companies recognize AI’s potential to optimize supply chains, enhance energy efficiency, and unlock new value streams. Sanchez also highlighted that AI not only drives demand for infrastructure but also serves as a key enabler for future efficiencies. Moreover, advancements in AI and processing power are already being incorporated into the design of next-generation data centers, reinforcing the necessity for continued development and investment in the sector.

In summary, data centers play a crucial role in the modern digital economy, supporting innovation and global connectivity. Their sustained growth trajectory, driven by AI, cloud computing, and enterprise digitalization, presents a strong investment opportunity. With backing from both corporate and government stakeholders, data centers will remain at the core of economic transformation, serving as vital infrastructure for the data-driven future.

The company’s long-standing relationships with major cloud providers and enterprises position the company well to capitalize on the ongoing AI-driven data surge. Looking ahead, although demand from data centers and mobile markets is expected to remain robust in Q3, the company expects that overall bit shipments may decline due to weaker demand in PC OEM and consumer markets. The first half of 2025 is anticipated to experience inventory adjustments, but a recovery is expected in the second half, fueled by AI-driven PC adoption during the Windows refresh cycle.

On March 7, a Cantor Fitzgerald analyst lowered its price target on Western Digital (NASDAQ:WDC) to $65 from $95 while maintaining an Overweight rating.

Overall, WDC ranks 9th on our list of best data center stocks to buy according to billionaires. While we acknowledge the potential of WDC to grow, our conviction lies in the belief that AI stocks hold greater promise for delivering higher returns and doing so within a shorter time frame.
