Stablecoin issuer Tether has significantly increased its Bitcoin holdings, transferring 8,888 BTC, valued at approximately $1 billion, to a known reserve wallet, according to on-chain data analyzed by Nansen and Arkham.
The transaction, which took place on the last day of the third quarter of 2025, originated from a hot wallet belonging to Bitfinex.
Bitfinex is a crypto exchange platform that shares a parent company with Tether. This relationship raises questions about whether the transfer represents a new purchase on the market or an internal reorganization of existing assets. Tether has not yet publicly confirmed the transaction.
This move is consistent with Tether's established pattern of accumulating Bitcoins at the end of each quarter.
The company began purchasing Bitcoins in September 2022 and formalized the strategy in May 2023, committing to invest 15% of its quarterly net operating profits in the cryptocurrency as part of a long-term diversification plan.
