While Nvidia (NASDAQ: NVDA) has dominated headlines over the past three years with staggering gains, another player, Seagate Technology (NASDAQ: STX), quietly stole the spotlight in 2025. Specialising in digital storage solutions, including hard-disk drives (HDDs) and solid-state drives (SSDs), Seagate achieved a remarkable 225% share price increase in 2025, far surpassing Nvidia’s 39% gain for the year. This strong performance reflects not only the company’s operational excellence but also the surging demand for data storage driven by artificial intelligence (AI) adoption across cloud and enterprise environments.
Rising Demand for Data Center Storage
Seagate Technology generates approximately 80% of its revenue from data center storage products, sold to cloud computing companies and large enterprises. Management has indicated that AI-driven demand for HDD storage is so robust that production capacity for 2026 is nearly sold out. CEO William Mosley highlighted during the October earnings call that longer-term agreements with global data center customers provide revenue visibility through calendar 2027, signaling sustained demand.
Market research from IDC estimates that global data generation could increase more than fivefold between 2020 and 2028 due to expanding AI applications. This growth trajectory implies that the data center storage market could more than double between 2024 and 2028, expanding Seagate’s addressable market from $13 billion in 2024 to approximately $23 billion by the end of the forecast period.
The current industrywide memory shortage has created a favorable pricing environment, with the contract price of HDDs rising an estimated 4% in Q4 2025, as reported by Tom’s Hardware. This price pressure is likely to continue into 2026, offering further upside to Seagate’s revenue and profitability.
Financial Performance Highlight
Seagate Technology’s fiscal results illustrate the tangible benefits of these market dynamics. In the first quarter of fiscal 2026 (ending October 3, 2025), the company reported a 21% year-over-year revenue increase to $2.63 billion. Non-GAAP operating margins jumped nearly nine percentage points to 29%, while earnings per share soared 65% year-over-year to $2.61. Analysts forecast a 42% increase in earnings for the current fiscal year to $11.52 per share, followed by sustained double-digit growth in subsequent years. These figures underscore the company’s strong earnings quality and its ability to capitalize on AI-driven storage demand.
Strategic Drivers and Competitive Edge
Seagate’s competitive advantage lies in its scale, long-term contracts, and technological expertise in both HDD and SSD products. Unlike some smaller peers, the company benefits from multi-year agreements with hyperscale cloud providers, offering predictable revenue streams and reducing exposure to short-term volatility. Additionally, Seagate’s diversified customer base, ranging from enterprise IT departments to global cloud operators, mitigates concentration risk and provides resilience against market shocks.
Analysts also note that the broader AI boom has created secondary tailwinds for Seagate Technology. Enterprises adopting AI workloads require extensive storage infrastructure, driving recurring demand for upgrades and expansions. Coupled with ongoing supply constraints, this dynamic has propelled both sales and pricing power.
Risks and Market Considerations
Despite strong fundamentals, potential risks remain. The data storage market is competitive, with players like Western Digital and Micron vying for market share. Seagate Technology’s reliance on HDDs for a significant portion of revenue could be a vulnerability if SSD adoption accelerates faster than anticipated. Additionally, any slowdown in global cloud spending or a correction in technology equity valuations could temper investor enthusiasm. Currency fluctuations, particularly between the U.S. dollar and key international markets, may also affect profitability.
From a macroeconomic perspective, central bank policy and interest rates are relevant. Higher borrowing costs could reduce enterprise IT investment or slow capital spending for data centers. Conversely, if global rates stabilize or decline, financing for infrastructure expansion may support continued growth in storage demand.
Valuation Outlook
Seagate Technology trades at roughly 25 times forward earnings, aligning with the tech-heavy Nasdaq-100 index. However, given its above-average earnings growth trajectory, the stock could command a premium in the future. If Seagate achieves projected earnings of $15.15 per share in the next fiscal year and trades at a 30x multiple, its stock price could reach $455, representing a potential 48% upside from current levels.
Implications for Investors and the Broader Economy
Seagate Technology’s performance highlights how AI adoption is reshaping hardware markets, providing opportunities beyond headline-grabbing semiconductor companies. For investors, the stock illustrates the value of targeting companies positioned to benefit from structural trends rather than relying solely on popular megacaps.
On a broader scale, surging demand for storage infrastructure reflects the accelerating digital transformation of global businesses. Enterprises and cloud operators expanding AI workloads are likely to increase capital spending, supporting equipment manufacturers and generating positive spillovers in technology services and logistics. This, in turn, may influence lending trends, as financial institutions consider technology infrastructure investments as a sector of strategic importance.
Seagate Technology’s impressive 2025 performance demonstrates that strong fundamentals combined with favourable macro and sectoral dynamics can outpace even high-profile AI leaders like Nvidia. While risks remain, the company’s revenue visibility, pricing power, and market positioning suggest that it could continue to deliver significant returns in 2026. For investors seeking to leverage the AI-driven expansion of data infrastructure, Seagate Technology represents a compelling opportunity in the global technology landscape.
