Lee Chan-jin (이찬진), head of South Korea\'s Financial Supervisory Service, voiced strong concern over overheating in single-stock leveraged exchange-traded funds tied to Samsung Electronics and SK Hynix. He said extreme turnover concentrates gains on brokerages and other intermediaries rather than individual investors, and said the watchdog is considering additional investor safety measures. Lee also criticised a failed SpaceX IPO allocation at Mirae Asset Securities and said inspections of related asset managers will be expanded.

South Korea\'s financial investment industry is facing a test of how it markets overseas blockbuster initial public offerings after failing to secure any SpaceX shares. OpenAI and Anthropic are seen as the next major overseas IPO candidates after each filed confidential S-1 registration statements with the U.S. Securities and Exchange Commission. Regulators are inspecting Mirae Asset Securities over the SpaceX subscription process, and a task force plans advertising rule improvements, potentially tightening disclosure in future IPO-related promotions.
