South Korea Tightens KOSDAQ Rules, Threatening Crypto Treasury Companies with Delisting

South Korea's newly revised KOSDAQ listing regulations are casting a long shadow over a growing class of publicly traded companies known as Digital Asset Treasuries, or DATs. Set to take effect on July 1, 2026, the updated rules introduce stricter market capitalization requirements that could force several crypto-heavy firms off the exchange entirely.

A Digital Asset Treasury is a publicly listed company whose core financial strategy revolves around accumulating cryptocurrency — primarily Bitcoin — as a primary balance sheet asset. The concept was pioneered in the United States by Strategy, the firm formerly known as MicroStrategy, and later adopted in Japan by Metaplanet. South Korean companies have now begun replicating this model, but the regulatory environment is shifting beneath their feet.

Under the revised framework issued by the Korea Exchange (KRX), KOSDAQ-listed firms must meet a market capitalization threshold of 200 billion KRW (approximately $145 million) by the end of 2026, rising further to 300 billion KRW (roughly $217 million) starting January 2027. Any company that falls below the required threshold for 30 consecutive trading days will be placed under managed stock status. From that point, firms have a 90-day window to recover, and must maintain the required valuation for at least 45 consecutive days to avoid automatic delisting.

The timing creates a direct problem for DAT companies. Many of these firms reported significant paper gains from Bitcoin holdings during the cryptocurrency's strong rally over the past year. However, those same gains now fall within the scope of the new retention thresholds, meaning regulators may scrutinize whether the underlying business can sustain the required capitalization independently of volatile crypto price movements.

This regulatory move is part of a broader trend. South Korean authorities have been systematically tightening oversight across the digital asset sector, addressing everything from exchange ownership limits to emerging stablecoin frameworks. The KOSDAQ revisions extend this pressure directly into the listed corporate space.

Among the most prominent examples of South Korea's DAT ecosystem is Bitplanet. The company was formed in July 2025 following an acquisition of KOSDAQ-listed SGA by a consortium that included Asia Strategy and Sora Ventures. Currently holding 300 BTC, Bitplanet has announced an ambitious long-term target of accumulating 10,000 BTC. CEO Lee Seong-hoon has publicly acknowledged that Strategy and Metaplanet served as direct inspirations for the company's treasury-focused business model, positioning Bitplanet as Korea's first dedicated listed crypto treasury vehicle.

Bitplanet is also working to diversify its revenue base. The company recently signed a memorandum of understanding with Nasdaq-listed Antalpha to deploy Bitcoin mining equipment worth approximately 15 billion KRW (around $10.8 million) at operational sites in Oman and Paraguay. Plans for AI data center development represent an additional revenue stream intended to complement the firm's core treasury accumulation strategy.

The structural question remains open. South Korea is consistently ranked among the world's largest retail cryptocurrency markets, yet the regulatory path for listed DAT firms is becoming increasingly narrow. How strictly authorities enforce the July 1 thresholds — and whether transparent crypto holdings can be reconciled with formal compliance standards — will largely determine the survival of this emerging corporate model.
