Metaplanet moves $108 million in Bitcoin to Coinbase Prime

Metaplanet transferred 1,350 BTC, valued at roughly $108 million, to a Coinbase Prime wallet. The move follows a separate transfer of 1,000 BTC on August 25, bringing the total moved to Coinbase Prime to 2,350 BTC within four days.

Purpose of the transfer

Coinbase Prime supports trading, custody, financing and collateral services. The deposit does not confirm a sale; it could simply place the coins under institutional custody or make them available for collateral.

Company’s reported holdings

Metaplanet officially reports a treasury of 43,000 BTC. On‑chain analytics attribute about 38,650 BTC to its tracked wallets, a difference that reflects undisclosed custodial addresses rather than a sale.

Historical context

Previous large movements from Metaplanet‑linked wallets have been clarified as custody re‑allocations. In August, the firm moved 3,881 BTC between custodial addresses without reducing its reported balance.

Financial backdrop

The company acquired its Bitcoin at an average cost of about ¥15.3 million per coin (≈ $96,200). At that cost, the 43,000 BTC treasury represents an estimated investment of roughly $4.14 billion. Recent market prices value the same amount at about $3.4 billion.

Related corporate activity

Metaplanet has announced a planned contribution of 2,100 BTC and $2.5 million cash to Nasdaq‑listed Super League Enterprise, a transaction that would give it a majority equity stake in the renamed entity.
