Metaplanet shares dropped 9.9 percent to 244 yen on Tuesday, bringing the two-day decline to about 17 percent, after a public note from CEO Simon Gerovich failed to reassure investors worried about dilution and insider dealings. The Tokyo-listed bitcoin treasury company fell 7.5 percent on Monday and another notch on Tuesday, and traders show no sign of letting the matter rest.
What triggered the selloff
The flashpoint is the company’s Series 10 stock acquisition rights, a plan that dates back to December 2022, long before Metaplanet became a bitcoin treasury firm. As the company issued new equity to fund bitcoin purchases, the pool of acquisition rights expanded with it. Critics argue insiders’ potential holdings grew while ordinary shareholders were diluted.
The board has frozen the pool at just over 319 million shares and added a lock-up, but that has not satisfied investors. They want the expanded rights cancelled outright and replaced with a new plan tied to the size of the pool at the moment the company pivoted to bitcoin.
Gerovich’s own moves feed the skepticism. Ten days after the cap was set, he exercised 92,000 units and received 64,032,000 shares. His direct holding rose to 79,587,500 shares, roughly 6.2 percent of the company.
The MMXX question
A second dispute involves MMXX Ventures, a disclosed Metaplanet shareholder whose structure investors say has never been properly explained. In his September 6 post on X, Gerovich conceded the company had not explained the subscription rights plan or MMXX’s organization well enough. He described himself as an important but non-controlling shareholder of MMXX’s parent company who does not take part in its transaction decisions.
Investors treated the statement as incomplete rather than reassuring. CoinDesk reported that shareholders say the hard questions remain unanswered, and the stock kept falling through both sessions.
| Session | Move | Close |
|---|---|---|
| Monday, Sept 8 | -7.5% | 271 yen area |
| Tuesday, Sept 9 | -9.9% | 244 yen ($1.56) |
| Two days combined | -17% | – |
Why the structure matters more than the coin
Metaplanet holds 43,000 BTC, making it the third-largest publicly traded bitcoin holder behind Strategy and Twenty One Capital. It bought 2,823 BTC for about $170.7 million in July, and its bitcoin income generation business earned roughly 4.72 billion yen, about $29.3 million, in the first half of fiscal 2026 through options-based strategies.
The treasury has also been building out new funding channels. In August, Metaplanet agreed to contribute 2,100 BTC to a Nasdaq-listed vehicle, Super League, which will be renamed Superplanet and act as its US treasury platform. This month it launched a continuous bond program, BitBonds, with the first private sale of about 200 million yen in four series carrying 4 to 4.3 percent annual interest.
None of that insulates the equity story from the current dispute. A company that funds itself through repeated equity issues depends on outside holders believing management’s incentives match theirs. Until the frozen pool, MMXX’s economics, and the August exercise are addressed in more detail, the market is likely to keep treating the CEO’s note as unfinished business.
The next test comes at the follow-up council of shareholders and analysts watching whether Gerovich offers concrete changes rather than another apology. Japanese disclosure rules give the company room to restructure the rights plan, but doing so would require board action and, in practice, cooperation from the same insiders who benefit from the current setup.
Bitcoin itself has been a sideshow in this selloff. BTC traded near $78,000 to $80,000 through the two sessions, so the slide is almost entirely a governance repricing rather than a crypto move. That distinction matters for anyone using Metaplanet as a listed proxy for bitcoin exposure: the proxy has developed its own risk factor.
For now, holders of the stock face a choice between waiting for a concrete plan and exiting into a falling tape. The company has given no date for further announcements.
