Metaplanet Moves 1,000 BTC Into Coinbase Prime Custody

Japanese bitcoin treasury firm Metaplanet transferred 1,000 BTC, valued at approximately $79.77 million, to Coinbase Prime custody on August 25, 2026.

Background on Metaplanet’s Holdings

Earlier in the week, the company disclosed that its total bitcoin balance had risen to 43,000 BTC. The average cost basis for this position is reported near $96,000 per coin, aligning with an aggregate cost of about $4.09 billion.

Recent Accumulation Pace

Metaplanet’s bitcoin stack grew from 1,761 BTC at the end of Q4 2024 to over 40,000 BTC within two years. The most recent purchase added 2,823 BTC for $225 million, cementing its status as Asia’s largest publicly traded bitcoin holder.

Purpose of the Custody Transfer

The move to Coinbase Prime is not identified as a sale. Potential reasons include securing regulated custody, enabling over‑the‑counter execution for future purchases, or supporting corporate transactions such as a recent contribution of 2,100 BTC to a Nasdaq‑listed venture.

Future Accumulation Goal

Metaplanet has set a target of 210,000 BTC by the end of 2027, funded primarily through equity issuances and structured products linked to its share price.
