Key Takeaways
Speculation has surfaced that the government is reviewing the development of a proprietary artificial intelligence (AI) model — dubbed "Mythos-class" — comparable to top-tier overseas models, funded by the increase in corporate tax revenue stemming from improved earnings at semiconductor companies. The government drew a firm line, stating "nothing has been decided," but given that the very discussion of a sovereign AI budget had already been partly priced in by the expectations of semiconductor- and AI-related listed companies, this denial reads instead as an episode exposing the gap between market expectations and policy reality.
What Happened
According to a Yonhap News report, speculation emerged from within and around the government that a frontier-level AI model development project would be pursued using surplus tax revenue generated by the semiconductor sector. The term "Mythos-class" is interpreted to mean a target performance level comparable to the top-tier foundation models released by overseas Big Tech firms such as OpenAI and Google.
In response, the government officially stated that the matter is "not something that has been decided." Rather than confirming or denying specifics on budget allocation or project launch, it denied the speculation itself.
What stands out is the timing of the denial. With the market already reacting to the sovereign AI theme, the government drawing an official line can also be read as a signal of caution against stock prices getting ahead of policy expectations that have yet to be finalized.
Background and Context
With the recent recovery in the semiconductor industry, earnings at major domestic semiconductor companies such as Samsung Electronics (005930) and SK hynix have reportedly improved, boosting related corporate tax revenue. This is not the first time discussion has arisen over how to use this extra fiscal room. The government has consistently listed the expansion of national AI computing infrastructure and the fostering of sovereign AI — that is, homegrown language models — as national policy priorities.
Overseas, government-led competition in AI investment continues. In the United States, private capital is driving massive data center investment, while Middle Eastern countries are deploying sovereign wealth funds to bet on AI infrastructure. Whether the Korean government will commit fiscal resources to developing a proprietary model will be determined within this broader context of international competition.
Market and Stock (Ticker) Impact
- Naver - As the only listed domestic Big Tech company with its own foundation model, including HyperCLOVA X, Naver could be cited as a preferred partner for public-sector AI adoption projects should a sovereign AI initiative materialize.
- Samsung Electronics (005930) / SK hynix - As both the source of the semiconductor windfall tax revenue behind this discussion and a core link in the HBM and server memory supply chain needed to train domestic AI models, these companies stand at a dual intersection of tax contribution and rising demand should government AI infrastructure investment increase.
- KT - As one of the three telecom carriers pursuing a full-stack AI strategy while operating its own large language model, KT could be considered a candidate for participation in public and government AI project consortiums.
- Small- and mid-cap listed AI solution providers such as Saltlux - Should the government actually allocate a budget, this is a segment where theme-driven buying could flow in on expectations of related service and solution contracts.
Investor Checkpoints
- Whether AI-related line items are separately reflected in the government's budget planning process for next year — watch the typical August–September budget announcement and National Assembly review schedule.
- The timing of official briefings from the Ministry of Science and ICT and other relevant ministries, or any policy announcements related to sovereign AI.
- Corporate tax-related indicators and the continued recovery of the semiconductor industry in Samsung Electronics' and SK hynix's next quarterly earnings.
- How the performance and cost gap with overseas frontier models from OpenAI, Google, and others affects the rationale for pursuing a domestic proprietary model.
Outlook
The optimistic scenario is one in which the government actually allocates a budget, channeling fiscal resources into the domestic AI ecosystem. In that case, foundation model developers along with semiconductor and cloud infrastructure companies could secure a stable revenue source from public-sector demand, providing grounds for a valuation re-rating. The risk, however, is a repeat of episodes like this one, where unsubstantiated speculation accumulates only policy uncertainty. Given that the government has firmly stated nothing has been decided, investors should be mindful of theme-driven volatility in related stocks until a concrete budget and implementing body are confirmed.
