South Korea floats AI profit social tax as tech giants boom

SEOUL — South Korea’s top economic policy official has proposed channeling excess profits from the country’s AI and semiconductor boom into a “national dividend” for all citizens. The proposal triggered a sharp sell-off in Seoul’s equity market.

Kim Yong-beom, senior presidential secretary for policy, laid out the framework in a speech on Monday. His remarks came as Samsung Electronics reported a 755 per cent surge in operating profit for the first quarter of 2026, driven by strong global demand for the high-bandwidth memory chips that power AI data centres. SK Hynix, the world’s second-largest memory chipmaker, has posted similar gains from the infrastructure buildout. Together the two firms control roughly 70 per cent of the global memory chip market.

“Using a portion of excess profits to ensure social stability for the current generation and mitigate transition costs is not merely redistribution, but also a type of system maintenance cost,” Kim said.

Markets fell immediately. The benchmark Kospi index dropped as much as 5.1 per cent in intraday trading — its steepest single-day decline in three months — and Samsung shares, which had quadrupled over the past year to push the company’s market value past $1 trillion, faced pressure from investors weighing the cost of a potential new levy on corporate earnings.

“The fruits of the AI infrastructure era are not the result of specific companies alone,” Kim said in a separate interview with the Asia Business Daily. “A portion of those fruits should be structurally returned to all citizens.”

This is among the most direct challenges yet by a senior government official to the concentration of AI-generated wealth in a handful of technology firms. South Korea has struggled to translate its export-led growth model into broad-based prosperity, and the semiconductor super-cycle has widened the gap between the country’s corporate champions and ordinary households. Wage growth has trailed productivity gains for much of the past decade. Housing affordability in the Seoul metropolitan area has become a persistent political issue.

The Alaska model, applied to silicon

The concept echoes resource-dividend frameworks used in jurisdictions such as Alaska and Norway, where revenue from oil and natural gas extraction is partially distributed to citizens through sovereign wealth funds or direct payments. Applying the same logic to AI and semiconductor profits would be novel. Kim offered no specifics on how the mechanism would be implemented — whether through a special corporate tax, a mandatory profit-sharing scheme, or a sovereign wealth fund-style structure funded by levies on the chipmakers.

“Even if the nation becomes wealthier, that wealth does not automatically spread,” Kim said. “South Korea has been strong in growth but weak in socially diffusing its fruits.”

The Blue House later clarified that the remarks reflected Kim’s personal policy vision rather than an immediate legislative proposal. The market’s reaction was clear. Semiconductor stocks across Asia fell: Taiwan’s TSMC dropped 2.8 per cent and Japan’s Tokyo Electron fell 3.1 per cent in afternoon trading. Investors across the region interpret the speech as a sign that governments enriched by the AI supply chain are beginning to ask questions about who captures the gains.

South Korea is not alone. French lawmakers have proposed a digital services levy on AI-training revenues, and policymakers in Brussels are considering whether existing windfall-tax frameworks could apply to the technology sector. What distinguishes Kim’s proposal is its framing: not a penalty on success, he argues, but a structural return to the society that made the success possible.

A divided assembly

The proposal arrives at a delicate political moment. President Lee Jae-myung’s administration is navigating a National Assembly split between his Democratic Party and the conservative People Power Party, and any mechanism that touches corporate taxation would require legislative approval that is not guaranteed. Business groups, including the Federation of Korean Industries, have already expressed opposition. They argue that the chipmakers’ profits are being reinvested in capacity expansion at a moment when the United States, China, and Japan are each pouring billions of dollars into domestic semiconductor manufacturing.

Samsung alone has committed 300 trillion won — roughly $205 billion — to a new semiconductor cluster in Yongin, south of Seoul, designed to secure the country’s competitive position in advanced logic chips as well as memory. A new tax on profits, the company’s allies in the assembly argue, would undercut that investment at a geopolitically sensitive moment.

Whether Kim’s national dividend advances beyond a policy speech depends on how the administration balances its redistributive approach against the reality that Samsung and SK Hynix are, for now, the engines of South Korean growth. The Kospi’s sharp drop shows investors are not waiting for the details to price in the risk.
