TLDR
- Metaplanet transferred 1,000 BTC worth roughly $79.77 million to Coinbase Prime on Aug. 25, but neither company has confirmed a sale.
- Coinbase Prime offers institutional custody, financing, and trading services, meaning the transfer does not confirm a disposal.
- Metaplanet holds 43,000 BTC valued at approximately $3.4 billion at current prices.
- Separately, Metaplanet agreed to contribute 2,100 BTC and $2.5 million to Nasdaq-listed Super League Enterprise, which will be renamed Superplanet with ticker SUPA.
- The Superplanet deal still requires shareholder approval and is targeting a Q4 2026 close.
Metaplanet moved 1,000 Bitcoin to wallets linked to Coinbase Prime on Aug. 25, according to blockchain analytics account Lookonchain. The transferred coins were worth approximately $79.77 million at the time.

Neither Metaplanet nor Coinbase has confirmed a sale took place.
Lookonchain described the transaction as a deposit into Coinbase Prime. The platform provides institutional custody, financing, and trading services. A deposit there can precede a sale, but it can also reflect standard treasury operations, collateral arrangements, or internal account management.
This is not the first time the company has faced this kind of attention. On Aug. 12, CEO Simon Gerovich clarified that Metaplanet had moved 5,014 BTC between custodial addresses without selling any coins. Analysts had initially flagged 3,881 BTC leaving Metaplanet-linked wallets during that episode. The company’s total holdings stayed at 43,000 BTC throughout.
Metaplanet’s Bitcoin Holdings
Metaplanet reported holding 43,000 BTC after acquiring 2,823 BTC during the second quarter. Its average acquisition price was roughly 15.3 million yen per coin, which Lookonchain converted to approximately $96,191.
At that average, the total acquisition cost comes to around $4.14 billion. The current market value sits near $3.4 billion, reflecting Bitcoin’s price movements rather than any change in the company’s coin count.
A transfer into Coinbase Prime does not automatically reduce Metaplanet’s beneficial ownership. The coins could remain fully under the company’s control through a different custodial arrangement. Confirming an actual reduction would require an explicit treasury disclosure or documented evidence of a sale.
Superplanet Deal Still Pending
Separately, Metaplanet agreed last week to contribute 2,100 BTC and $2.5 million in cash to Super League Enterprise. The Nasdaq-listed company would be renamed Superplanet and trade under the ticker SUPA.
In exchange, Metaplanet would receive 44.86 million common shares, preferred shares, and warrants. The company expects to own approximately 95.7% of the resulting entity after closing.
The 2,100 BTC contribution is expected to remain within Metaplanet’s consolidated group after the deal closes.
There is no official evidence connecting Tuesday’s 1,000 BTC transfer to the pending Super League transaction. The timing, one week apart, invites the question, but neither company has made that link.
Ahead of the larger deal, Super League sold 475,598 shares for approximately $2.23 million in gross proceeds through an at-the-market offering. It subsequently authorized another $2.27 million in ATM capacity for future sales. Agents in the program collect a 1% commission on gross proceeds.
The Superplanet transaction still requires Super League shareholder approval, Nasdaq compliance, and regulatory procedures in both the U.S. and Japan. Both companies are targeting a Q4 2026 closing.
Until Metaplanet issues a fresh treasury disclosure, the confirmed fact is a 1,000 BTC movement to Coinbase Prime custody.
