Metaplanet transferred 1,000 Bitcoin, worth approximately $79.77 million, to wallets attributed to Coinbase Prime on Aug. 25, according to blockchain analytics account Lookonchain.
The Transfer
Lookonchain described the transaction as a deposit into Coinbase Prime, which provides institutional trading, financing and custody services. Moving Bitcoin there can precede a sale, but it can also reflect custody management, collateral arrangements or internal account transfers. Neither Metaplanet nor Coinbase had identified the latest movement as a sale when checked.
The transfer follows several large movements involving the Japanese company's 43,000 BTC treasury. Metaplanet has addressed similar speculation before. On Aug. 12, CEO Simon Gerovich said the company moved 5,014 BTC between custodial addresses without selling any coins. Its reported holdings remained unchanged at 43,000 BTC at that time.
43,000 BTC Treasury Context
Metaplanet reported holding 43,000 BTC after acquiring 2,823 BTC during the second quarter. Its disclosed average acquisition price was approximately 15.3 million yen per coin, which Lookonchain converted to an estimated $96,191. At that average, the position's estimated acquisition cost would be approximately $4.14 billion. The latest transfer does not necessarily reduce Metaplanet's holdings, as Bitcoin held through a Coinbase Prime account could remain under the company's beneficial ownership.
The Superplanet Transaction
The transfer comes one week after Metaplanet agreed to contribute 2,100 BTC and $2.5 million to Nasdaq-listed Super League Enterprise. The proposed transaction would turn Super League into a U.S. Bitcoin treasury platform named Superplanet, with Metaplanet receiving 44.86 million common shares, preferred shares and warrants. It expects to own approximately 95.7% of the resulting company.
There is no official evidence connecting the 1,000 BTC transfer with that transaction. The timing permits the possibility, but neither company has identified the transferred coins as part of the pending contribution. The 2,100 BTC contribution would remain within Metaplanet's consolidated group after closing.
Super League ATM Program
Separately, Super League reported selling 475,598 shares for approximately $2.23 million in gross proceeds through its at-the-market program. The company subsequently authorized another $2.27 million of ATM capacity, representing shares available for future sale rather than completed financing. The larger Superplanet transaction still requires Super League shareholder approval, Nasdaq requirements and applicable procedures in the U.S. and Japan, with a fourth-quarter 2026 closing target.
Why Blockchain Transfers Are Not Always Sales
The transfer highlights why blockchain movements should not automatically be treated as disposals. Bitcoin can move between custodial accounts for operational reasons without changing beneficial ownership. An official treasury update or evidence of subsequent asset sales would be needed to confirm a reduction in Metaplanet's holdings. Until Metaplanet issues another treasury disclosure, the verified development is a 1,000 BTC movement to wallets attributed to Coinbase Prime.
