Metaplanet Transfers 1,000 BTC to Coinbase Prime
Japanese investment firm Metaplanet transferred 1,000 Bitcoin, worth approximately $79.77 million, to Coinbase Prime on Aug. 25, according to blockchain analytics account Lookonchain. The destination was attributed to wallets tied to Coinbase Prime, though neither Metaplanet nor Coinbase had identified the latest movement as a sale when checked Tuesday.

- Reported Metaplanet holdings: 43,000 BTC
Why the transfer alone does not prove a sale
Custody and institutional services
Coinbase Prime is an institutional platform offering trading, financing and custody services. Moving Bitcoin to Prime can precede a sale, but it can also reflect custody management, collateral arrangements or internal account transfers.
Lookonchain described the transaction as a deposit: “Metaplanet deposited another 1,000 BTC into Coinbase Prime 1 hour ago.” The analytics firm also noted that Metaplanet bought 43,000 BTC at an average price of $96,191, and that the latest deposit was worth $79.77 million. The destination attribution is an on-chain analyst’s assessment, not confirmation that Coinbase executed a sale.
Earlier movement: 5,014 BTC between custodial addresses
On Aug. 12, Metaplanet CEO Simon Gerovich said the company moved 5,014 BTC between custodial addresses without selling any coins. Analysts had initially observed 3,881 BTC leaving Metaplanet-linked wallets during that earlier movement. Subsequent company clarification showed why a blockchain transfer should not automatically be treated as a disposal. Metaplanet’s reported holdings remained unchanged at 43,000 BTC.
Metaplanet’s 43,000 BTC requires price 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. Lookonchain’s separate $3.48 billion figure represents an approximate market valuation near current prices, rather than the amount Metaplanet originally paid. At the time of the report, Bitcoin traded around $79,772.
The latest transfer also does not necessarily reduce Metaplanet’s holdings. Bitcoin held through a Coinbase Prime account could remain under the company’s beneficial ownership. An official treasury update or evidence of subsequent asset sales would be needed to confirm a reduction.
Pending U.S. Bitcoin treasury 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.
Metaplanet would receive 44.86 million common shares, preferred shares and warrants. It expects to own approximately 95.7% of the resulting company, with the planned Nasdaq ticker SUPA. The 2,100 BTC contribution would remain within Metaplanet’s consolidated group after closing, and the companies valued the initial investment at about $134.6 million.
There is no official evidence connecting the Aug. 25 transfer of 1,000 BTC with that transaction. The timing permits the possibility, but neither company has identified the transferred coins as part of the pending contribution.
Super League completes first ATM allocation
Separately, Super League reported selling 475,598 shares for approximately $2.23 million in gross proceeds through its at-the-market (ATM) program. The completed sales followed an Aug. 18 agreement with Benchmark and StoneX.
The company subsequently authorized another $2.27 million of ATM capacity. That additional amount represents shares available for future sale, not completed financing. Agents receive a 1% commission on gross proceeds from each sale.
The larger Superplanet transaction still requires Super League shareholder approval, Nasdaq requirements and applicable procedures in the U.S. and Japan. The companies are targeting a fourth-quarter 2026 closing.
Bottom line
Until Metaplanet issues another treasury disclosure, the verified development is a 1,000 BTC movement to wallets attributed to Coinbase Prime. Describing it as a confirmed sale would go beyond the available evidence.
