On the morning of June 16, Metaplanet – a software company listed on the Tokyo Stock Exchange – announced the issuance of 210 million USD in zero-interest bonds to purchase additional Bitcoin.

Specifically, at the Board of Directors meeting on the same day, Metaplanet approved the plan to issue its 18th series of regular bonds with a total value of 210 million USD, an interest rate of 0%, with no collateral or guarantees. Each bond has a face value of 5 million USD and will be repaid in full on the maturity date of December 12, 2025.

All of these bonds are exclusively distributed to the EVO FUND institutional investment fund, which has conducted several large transactions with Metaplanet. According to the agreement, EVO FUND can request Metaplanet to repay all or part of the bonds early, provided that a notice is sent at least 5 working days in advance.

Notably, Metaplanet has also implemented a special mechanism: if the company continues to receive additional capital from EVO FUND in multiples of the bond's face value (i.e., each additional amount of 5 million USD), Metaplanet can use that money to repay part of the issued bonds, even before the payment is due.

According to CEO Simon Gerovich, Metaplanet has spent 117.2 million USD to acquire an additional 1,112 BTC at an average price of about 105,435 USD/BTC on June 16.

This transaction has officially increased the total number of BTC held by the company to 10,000 BTC (over 1 billion USD), surpassing the 9,267 BTC currently held by Coinbase. This information has caused Metaplanet's stock to surge by 21.74%, reaching 1,837 yen/share, increasing the total rise since the beginning of 2025 to over 408%.
