As memory chips become a critical bottleneck in the expansion of AI data centers, technology giants are increasingly seeking stable supply agreements. Recent reports indicate that Samsung Electronics is engaged in advanced negotiations with Alphabet and Microsoft regarding long-term supply contracts. Sources familiar with the matter reveal that discussions with Microsoft involve a prepayment arrangement exceeding $10 billion. Should the actual purchase volume fall short of the agreed-upon amount, the difference would be deducted from this substantial prepayment.
The significance of such an agreement extends beyond a single transaction. Analysts suggest that if finalized, long-term contracts would provide memory manufacturers with demand visibility stretching over three years. This enhanced foresight is expected to help mitigate severe price fluctuations, support stable profit margins, and enable more predictable capital expenditure planning.
The contractual structure under discussion reportedly links volume and price. The most likely model involves locking in purchase volumes for multiple years while tying the pricing mechanism to the spot market. Contract prices would be adjusted if spot market prices deviate from a pre-defined range. Within this framework, the tech giants would make significant prepayments to Samsung. Failure to meet the agreed purchase volumes over the three to five-year contract period would result in deductions from these prepayments. Sources indicate the prepayment being discussed with Microsoft surpasses $10 billion. A key feature of these new agreements is their binding nature, a contrast to some past agreements around 2019 that lacked strong enforcement mechanisms and allowed clients to unilaterally cancel orders. The current prepayment design is intended to ensure contract performance.
Samsung is not alone in this trend. Micron Technology is also pursuing similar arrangements and has disclosed its first five-year Strategic Customer Agreement (SCA) in its Q2 FY2026 earnings report. Industry sources expect memory suppliers to finalize long-term supply agreements with major technology companies in the first half of this year. Micron's capital expenditure plans reflect the direct impact of improved demand visibility on investment decisions. The company has announced a FY2026 CAPEX plan exceeding $25 billion, nearly double the $13.8 billion from the previous fiscal year. Should Samsung's long-term agreements materialize, a similar expansion in its capital expenditure is anticipated.
Market structure evolution is further driving the adoption of long-term contracts. With the introduction of next-generation products like HBM4, the proportion of customized High Bandwidth Memory (HBM) in the overall memory market is set to rise. As clients increasingly collaborate with suppliers from the design phase, the demand for three to five-year contracts is expected to grow. Historically, the memory industry has been plagued by cyclicality, where massive capacity expansions often misalign with demand fluctuations, leading to volatile prices. If this new model of prepayment-backed long-term agreements becomes established, it could provide an unprecedented demand-anchoring mechanism, reducing uncertainty for both supply and demand sides of the market.
