AI Turned Samsung: There is a small, silver-gray chip inside nearly every AI system running on the planet right now. It is called high-bandwidth memory, or HBM, and without it, Nvidia’s most powerful GPUs cannot function.
The company that makes a significant share of the world’s supply of this chip is Samsung Electronics, a South Korean conglomerate whose three fabrication complexes outside Seoul have quietly become among the most consequential facilities in the global economy. On May 21, 2026, roughly 45,000 of the workers who run those facilities are scheduled to walk off the job.
If the strike proceeds as planned, it will be the largest work stoppage in the entire history of semiconductor manufacturing. And it is not happening because conditions at Samsung are uniquely terrible, or because the company is struggling. Quite the opposite. Samsung’s semiconductor division is in the middle of a historic profit surge, driven almost entirely by the explosive global demand for AI infrastructure. The workers want a share of that surge, and they are not getting it without a fight.
The conflict has its roots in a compensation structure that Samsung’s own largest union has called fundamentally broken. In 2024, Samsung paid no performance bonuses at all after its chip division posted operating losses during a period of oversupply in the global memory market. Workers understood that. What they did not expect was what came next.
In the first quarter of 2026, Samsung’s operating profit increased nearly eightfold compared to the same period the year before, reaching a record high on the back of AI chip demand. The workers whose labor produced that result received nothing from the windfall under the existing cap, which limits performance bonuses to 50 percent of an employee’s base salary. That cap was set during a different era of the semiconductor business, before AI transformed memory chips from a low-margin commodity into a product that Apple reportedly agreed to pay double its previous price for in emergency negotiations earlier this year.
Samsung’s largest union has framed the situation plainly. In a statement released last month, the union said the semiconductor industry is now “facing a war to secure global talent,” and that Samsung is losing that war because it refuses to update its compensation structure. The union’s demands include allocating 15 percent of operating profit to a bonus pool, removing the existing cap on bonuses entirely, and a seven percent wage increase across the board.
If the memory division gets 500 million won while the foundry division only gets 80 million won, what motivation would those employees have to keep working?”
Management has countered with roughly 13 percent of operating profit, but only as a one-time payment tied to 2026 performance, with no commitment to permanent structural changes. For the union, that offer misses the point. They are not just asking for more money this year. They are asking Samsung to fundamentally rethink how it compensates the workforce that has made it one of the most valuable technology companies in the world.
The Rival That Changed Everything
No single development has done more to accelerate this labor dispute than the moves made by Samsung’s chief competitor, SK Hynix. Last September, SK Hynix reached a settlement with its own union that allocated 10 percent of annual operating profit directly to employees as performance bonuses, locking in that structure for a decade and removing caps on payouts. Based on 2026 profit forecasts, that arrangement translates to average bonuses of roughly $460,000 to $477,000 per worker this year across SK Hynix’s 35,000 employees, with projections approaching $900,000 per person in 2027.
The numbers are extraordinary by any standard, but they are the product of an extraordinary market. SK Hynix held 62 percent of the global HBM market as recently as last year, when Samsung was still struggling to get its HBM3E chips to meet Nvidia’s qualification standards. The gap has since narrowed, but the talent damage has already begun. Samsung union chairman Choi Seung-ho confirmed that roughly 200 Samsung engineers left for SK Hynix in just the past four months. In a field where institutional knowledge of a specific fabrication line can take years to develop, those defections represent a real competitive wound.
The Stakes for the Global AI Supply Chain
This is not a labor dispute that will stay contained within South Korea. Samsung makes approximately a third of the world’s DRAM, the memory chips inside virtually every phone, laptop, server, and data center on the planet. Its fabrication complexes are among the most difficult manufacturing facilities ever built, and they are essentially irreplaceable in the near term. The tech giants scrambling to build out AI infrastructure — Google, Amazon, Microsoft — depend on Samsung’s output in ways that have no easy backup plan.
A preview of what a full stoppage might look like came in April, when a single-day walkout hit Samsung’s operations. During that affected shift, foundry output reportedly dropped 58 percent and memory fabrication fell 18 percent. Management has already begun what the industry calls “warm-down” procedures — scaling back the flow of new silicon wafers into the fabrication process — because halting chip production mid-cycle means scrapping wafers that cost roughly $20,000 each.
Industry estimates of the potential damage from an 18-day full stoppage range from 30 trillion to 100 trillion Korean won. JPMorgan analyst Jay Kwon has put the operating profit impact at roughly 2.1 trillion to 3.5 trillion won in his base case, with significantly worse outcomes if the strike expands or recovery is slow. KB Securities analyst Kim Dong-won noted that restarting Samsung’s highly automated production lines after an extended stoppage would require an additional two to three weeks of stabilization work, meaning the effective disruption window could stretch to six weeks in total.
Samsung must enable foundries to become self-reliant. The current structure creates internal conflicts of interest and depresses the company’s overall stock valuation.”
A Tentative Resolution: AI Turned Samsung
After a 17-hour negotiation session at South Korea’s National Labor Relations Commission on May 13 failed to produce a deal, both sides remained deadlocked heading into the week of the strike deadline. Samsung sent a letter to union leadership proposing a return to direct dialogue, which the union agreed to on the condition that co-CEO Jun Young-hyun personally attend and present concrete proposals on the key outstanding issues.
On Wednesday, May 20, the two sides announced a tentative deal had been reached. As part of the agreement, Samsung agreed to scrap the existing cap on bonuses and committed to allocating 10.5 percent of business performance profits as the funding source for employee bonuses. In a brief statement, Samsung acknowledged the agreement “came later than expected” and said it would “work to build a more mature and constructive labor management relationship” going forward.
The tentative deal still requires approval through an internal union vote. Whether the rank and file accept the terms — or whether the strike that was scheduled to begin today is ultimately averted — remained uncertain as this article went to publication.
A Broader Question
The Samsung dispute is, in one sense, a straightforward collective bargaining fight over wages and profit-sharing. In another sense, it is something more significant: a visible argument about who owns the gains of the AI economy, and whether the workers who physically build its infrastructure have any legitimate claim to them.
That question surfaced in unexpected places this month. South Korea’s presidential policy chief posted publicly on social media arguing that the country’s citizens should receive a kind of “dividend” from the AI boom, comparing the idea to Alaska’s Permanent Fund, which distributes a share of the state’s oil revenues to residents. The comparison carries weight, because the gains at Samsung and SK Hynix were built on decades of public investment in South Korean industrial infrastructure and engineering education. The two companies are projected to pay more than 100 trillion won in corporate taxes on their 2026 profits alone.
Whether those broader arguments find any traction in policy circles remains to be seen. What is clear is that the workers at the center of the AI boom — the ones in clean rooms and fabrication floors, not in boardrooms or on earnings calls — have decided they are no longer willing to be passive observers of the wealth they help create. For the global technology industry, that shift in expectations may prove to be as consequential as the chips themselves.
