Samsung Electronics is facing one of the most challenging weeks in recent history. Over 45,000 of the company’s workers in South Korea are preparing for an 18-day strike starting May 21, amid a rising cycle of memory demand driven by artificial intelligence (AI). If it materializes, the strike could disrupt the production of DRAM and NAND, two essential components for AI servers, computers, smartphones, and SSD units.
The timing couldn’t be worse. The memory market is experiencing unusual tension after months of rising prices, tight inventories, and capacity reallocation toward higher-margin products like HBM for AI accelerators and server memory. Against this backdrop, a labor stoppage at the world’s largest memory manufacturer adds pressure to an already strained supply chain.
The upcoming strike is primarily driven by a dispute over wages and bonuses within Samsung. According to Reuters, discontent has increased due to differences in incentives offered to workers in various semiconductor divisions. The memory division, benefiting from the AI surge, reportedly received bonus proposals far surpassing those for areas like logic and chip fabrication, fueling an internal division within the company that is uncommon.
A strike with impacts beyond South Korea
The union demands a bigger share of the profits generated by the booming semiconductor cycle. Their key requests include eliminating the 50% cap on certain bonuses and linking part of their compensation to annual operating profits. The core issue is clear: workers want a larger share of the prosperity that AI has brought to the memory business.
Samsung has attempted to contain the conflict, and the South Korean government has also stepped in to prevent a large-scale clash. Reuters reported on May 17 that Prime Minister Kim Min-seok has proposed using “all options” to prevent the strike, including possible emergency mediation that would impose a 30-day pause on industrial action while negotiations continue. Samsung and the union plan to resume talks with a government mediator on Monday, May 18.
The political dimension is straightforward. Samsung is not just another company in South Korea. Reuters estimates it accounts for 22.8% of the country’s exports and around 26% of the market capitalization of the South Korean stock market. Halting critical semiconductor lines would not only impact the company’s finances but also have broader consequences for the national economy, international clients, and the confidence of major tech buyers.
Some estimates already indicate a significant impact on global supply. TrendForce, at the end of April, suggested that a prolonged strike could affect 3-4% of global DRAM production and 2-3% of NAND, based on analyses linked to the production facilities in Pyeongtaek and Hwaseong. While these figures may seem small, even a few percentage points of reduced supply can influence prices, delivery times, and purchasing strategies in a tight market.
Memory prices were high even before the strike
The upward pressure on RAM and SSD prices predates the labor dispute. AI has shifted the market dynamics. Major cloud providers, server manufacturers, and companies deploying AI clusters are absorbing large volumes of high-performance memory. This primarily impacts HBM and server DRAM but also displaces capacity and adds tension to segments like PC, laptop, and consumer SSD modules.
TrendForce had already increased its price forecasts for the first quarter of 2026 due to strong AI and datacenter demand. Recent reports indicate inventories are declining among suppliers and high-end applications are consolidating profits. In NAND, demand from AI servers and enterprise SSDs is also prompting manufacturers to prioritize higher-value products.
Therefore, the risk of a strike comes at a critical time for consumers and OEMs. Throughout 2025 and early 2026, many users have already experienced rising costs for PC upgrades, especially high-capacity DDR5 memory and SSDs. If Samsung reduces production or shifts focus to strategic lines like HBM, the pressure could quickly transfer to other segments.
Tom’s Hardware, citing South Korean media and market analyses, reported that Samsung has already taken preventive measures ahead of the strike, such as reducing new wafer inputs and adjusting processes on some lines to mitigate risks. TrendForce also mentioned cautious measures and possible prioritization of higher-value products like advanced DRAM and HBM, due to potential disruptions.
This matters because a semiconductor factory doesn’t turn on and off like an office. The lines operate continuously, processes are lengthy, and any stoppage can cause delays that extend beyond the formal strike period. Even if the strike lasts 18 days, recovery could take additional weeks in certain manufacturing stages.
SK Hynix and Micron may benefit but won’t solve the problem
Samsung’s rivals are watching closely. SK Hynix and Micron already have strong positions due to demand for AI memory, especially HBM and server DRAM. An interruption at Samsung could lead some clients to seek more volume from other suppliers, although available capacity is limited.
TrendForce warned on May 13 that Samsung’s revenue impact might be partially contained if lower supply drives up the average selling prices (ASPs) of DRAM and NAND. However, large buyers may also shift orders to SK Hynix and Micron to reduce supply risk. This highlights a paradox: while a strike could harm Samsung’s output, the upward trend in memory prices might cushion some financial losses if prices continue to rise.
For end-users, the outlook is less optimistic. If uncertainty persists, PC, laptop, server, and SSD manufacturers may accelerate purchases, increase inventories, or frontload orders. Such defensive behavior often fuels further price hikes, especially in a market already under pressure.
Memory has regained its status as a strategic component. Once a cyclical market with sharp price drops after periods of oversupply, AI has changed this dynamic. Demand for HBM, enterprise servers, SSDs, and large data centers is absorbing capacity previously available to other segments. This creates a less flexible supply chain more vulnerable to labor, geopolitical, or energy shocks.
Samsung enters this situation with a complex position. On one hand, it benefits from an extended demand cycle for memory not seen in years. On the other, its workforce demands that these gains are reflected more fairly in wages and bonuses. The strike scheduled for May 21 is not just an internal dispute; it signals how wealth generated by AI is starting to cause tensions within the very factories that support the digital infrastructure.
Next week will be decisive. If mediation prevents the strike, the market will breathe a sigh of relief, though memory prices will likely remain under pressure from AI demand. Conversely, if the strike begins and continues, the effects could ripple through the global DRAM and NAND supply chain—from high-performance servers to consumer SSDs. The industry has learned that demand, clients, and technology are not enough; stable labor conditions in the factories producing the most fundamental and critical chips are equally essential.
Frequently Asked Questions
When is Samsung’s strike expected to begin?
The strike is scheduled to start on May 21, 2026, and could last 18 days, though the South Korean government is trying to mediate to prevent it.
How many workers would participate?
Reuters reports over 45,000 employees involved in the threat of strike, as part of a dispute over wages and bonuses at Samsung Electronics.
Could RAM and SSD prices rise?
Yes. Memory was already under upward pressure due to AI demand. An interruption at Samsung could reduce DRAM and NAND supply and trigger further price increases.
Which products might be affected?
Primarily DRAM, NAND, server memory, enterprise SSDs, and indirectly consumer RAM modules and SSDs if supply disruptions escalate in the broader market.
