Metaplanet moves 1,000 BTC to Coinbase Prime

Metaplanet transferred 1,000 Bitcoin, valued at roughly $80 million, to wallets attributed to Coinbase Prime on August 25, according to blockchain analytics from Lookonchain. The move does not confirm a sale, as Coinbase Prime offers institutional custody, trading and financing services.

Background on Metaplanet’s Bitcoin holdings

The company officially holds about 43,000 BTC, a position valued near $3.4 billion at current market prices. Earlier in the quarter, Metaplanet acquired an additional 2,823 BTC, reporting an average acquisition price of approximately ¥15.3 million per coin (about $96,191). This suggests an estimated acquisition cost of roughly $4.14 billion for the total treasury.

Nature of the Coinbase Prime transfer

Lookonchain described the transaction as a deposit into Coinbase Prime. Because Coinbase Prime serves as a custodial platform, moving Bitcoin there can be part of custody management, collateral arrangements, or internal account transfers, and does not necessarily indicate a disposition.

Relation to the Super League transaction

Metaplanet recently agreed to contribute 2,100 BTC and $2.5 million to Nasdaq‑listed Super League Enterprise, which aims to become a U.S. Bitcoin treasury platform named Superplanet. The contribution would remain within Metaplanet’s consolidated group after closing, and the larger transaction still requires shareholder approval and regulatory clearance, with a target closing in Q4 2026. No official link has been made between the 1,000 BTC transfer and this pending contribution.

Super League’s recent financing activity

Super League sold 475,598 shares for approximately $2.23 million in gross proceeds through an at‑the‑market (ATM) program, following an agreement with Benchmark and StoneX on August 18. An additional $2.27 million of ATM capacity was authorized for future sales.
