Key Takeaways
- JPX is tightening listing rules for firms with large crypto treasuries.
- Three companies have already been blocked from listing as scrutiny grows.
- More than 50 firms now sit on unrealized crypto losses, signaling the end of the DAT boom.
Japan Exchange Group (JPX), operator of the Tokyo Stock Exchange (TSE) and Osaka Exchange (OSE), is taking a hard look at companies holding large cryptocurrency reserves, signaling that the Digital Asset Treasury (DAT) trend may have finally gone too far.
According to industry sources, JPX has halted the listing of three firms with large crypto holdings while it reconsiders new compliance and disclosure standards.
The exchange operator has also warned that future listings could face tighter reviews, particularly for companies whose primary business model revolves around acquiring or holding Bitcoin.
The move comes as dozens of publicly traded DAT firms face mounting unrealized losses — the first real test for a strategy that once promised to make corporate balance sheets more “digital-age ready.”
JPX Tightens Listing Rules
JPX’s new stance marks a major policy shift for Japan’s public markets.
The exchange group, which oversees roughly 90% of listings in Japan, said it is concerned that new issuers are using crypto accumulation as a backdoor listing tactic, raising both governance and investor-protection red flags.
Sources familiar with the matter said three potential DAT listings have been blocked while the exchange considers additional auditing, disclosure, and fundraising restrictions.
JPX officials reportedly warned that companies overly reliant on speculative crypto holdings may face financing limits or additional listing scrutiny.
Metaplanet CEO Simon Gerovich, whose company is among Japan’s largest corporate Bitcoin holders, defended his firm’s compliance record on X:
“JPX’s concerns are with companies suspected of backdoor listings or pivoting without approvals. Metaplanet held five shareholder meetings over two years for all changes—governance is our foundation.”
Japan leads Asia with 14 Bitcoin treasury firms, but the DAT sector’s steep price drops have rattled investors.
Metaplanet shares, once a retail favorite, have plunged over 75% since May, spurring the exchange to reconsider how DAT firms are regulated and audited.
The DAT Bubble Is Deflating
What began as an exciting experiment in corporate treasury management has turned into a cautionary tale.
The Digital Asset Treasury boom exploded in 2025 as companies sought to mimic MicroStrategy’s success with Bitcoin reserves.
Hundreds of firms worldwide raised funds to buy cryptocurrencies like BTC, ETH, and SOL, touting them as long-term balance-sheet assets.
Now, that narrative is showing cracks.
Bitcoin’s decline from $125,000 to below $105,000 has left many DATs in the red.
Analysts estimate over 50 crypto treasury firms are nursing unrealized losses, with ETH and SOL-heavy portfolios hit the hardest.
Stock prices of DAT firms, which soared alongside Bitcoin in May, have since cratered, with some losing more than 80% of their value.
Who’s Hurting the Most
- Metaplanet Inc. — Dubbed Japan’s MicroStrategy, the company holds more than 30,000 BTC but now faces $120 million in unrealized losses. Its stock has plunged 82% from a May peak of ¥15.35 to ¥2.66.
- BitMine Immersion Technologies — The largest corporate ETH holder, BitMine is down 20% year-to-date, with $2 billion in unrealized losses as ETH slips below $3,500.
- SharpLink Gaming — Another major ETH treasury holder, down over 20%, despite freezing new crypto purchases for the last three months.
- Nakamoto Holdings — Once a high-flyer, its stock has fallen 95% since May amid Bitcoin’s decline.
Across the board, DATs holding BTC, ETH, SOL, and XRP report paper losses between 4% and 15%, reflecting a market that may have overextended itself.
A Familiar Pattern
Every crypto cycle seems to produce its own bubble.
In 2017, it was ICOs.
In 2021, NFTs and the metaverse.
Now, in 2025, it’s crypto treasuries or DATs.
JPX’s move may mark the start of that correction in Japan.
